Hey Josh, I’ve had good luck using a little White Diamond Metal Polish or whatever metal polish I happen to having laying around on journals, after sanding. That kinda fills those grooves in. Not sure how long it lasts, it’s probably overkill but, if you put some time into it, you can really get scratched up journals looking nice before tossing the bearings in.
My factory apprenticeship began over 50 years ago. In unit repair the men used 50/50 STP and engine oil for assembly lube. They taught me to use white lithium sparingly on threaded parts after thoroughly cleaning the threads or sparingly on new threads such as spark plugs. I have been working on alloy engines as an occupation or second job ever since. Never had a problem if I took my time and never heard of using white lithium on rods or anything else internal.
Josh never apologize for the long format videos . Many of us don’t watch Television anymore more and these are our new shows . So instead of you apologizing for it myself and many others would like to say thank you for the longer ones.
Not sure if it’s worth a court battle. Yes it’s a financial loss, but taken time off from the road and probably paying at least a 10,000 Dollar retainer for a good attorney is even more money spent. I had a trucking business and bad service gets written off as a business expense. Just learn from it and do your research before the rebuild.
I agree with you on that, it would be a different story if he charged for cat parts and used aftermarket. This is just a ram jam mechanic who put this motor together, and you’ve got to write it off and know next time put forth due diligence in picking a good shop and mechanic to do quality work.
Thanks Josh, I will be rebuilding a 1998 Cummins N14 - considering its age, I've decided to pull it from the (diesel pusher) motorhome, strip it down to the bare block & build it back up on an engine stand. I've saved a lot of your videos for reference, this one's getting filed under "how NOT To build an engine." My poor German Shepherd jumped up & came over to render aid & emotional support, I was moaning & groaning so much after seeing the damage done to that beautiful truck. Love the longer, more in depth videos shot while you work - the "here's how I do it & here's why..." is tremendously helpful. Thank you!!

I'm currently doing an inframe on a 8.3 Cummins. It's also a 1998. It was supposedly rebuilt 40K miles before I bought it. I'm finding a lot of crap work was done on it, but nothing as idiotic as what we've seen here today. I've been watching Josh's videos and he definitely has great advice and it's helped me a ton, even though I don't own a CAT engine.
FCbrants, Is there any chance you'd be willing to film your rebuild for those of us who enjoy watching engine rebuilds for entertainment? I'm not a mechanic, but I play one at home. 👍😁
On N14s check the oil pump gear end clearance. 0.008" is max. And brand new pumps. Come at max clearance resulting in low pressure running. Have the housing lapped to bring the clearance to 0.0045" to 0.005"
@@Fucktard2 That's a definite possibility - we haven't dropped the engine yet, still building the "jack stands" to hold the motorhome Very, Very steady, 6 feet in the air, so we can actually drop the engine, Vs. paying $45k + for a column lift system, or cutting the fiberglass rear cap off to get the engine out. So, you haven't missed anything exiting yet. P.S., I'm not a mechanic either, but Cummins has a great service manual & there's tons of info online, so fingers crossed.
You josh have built a reputation of doing it right. I actually like watching long videos of people doing the job correctly it teaches us to be patient and pay attention.
Learned that one the hard but yet forgiveable way. In high school mechanics class we tore down a bunch of junk engines and put them back together. I got this old dodge 6 cylinder swather engine that had been dusted. Mixed up the caps when taking them back and forth to the parts washer. Threw the engine back together. Go to try and turn the crank to start putting rods in and it’s locked up solid. That was over 15 years ago and I never forgot that moment.
Having rebuilt a lot of Cat engines successfully I think attention to detail, cleanliness and organization are three major keys. It has always amazed me how tolerant engines are to improper assembly. It is not rocket science. If the OEM doesn't do you probably do not need to. If they tell you to do things a certain way they probably have a good reason. Great video! RFTB!
longer videos, shorter videos...makes no difference. Keep 'em coming. Great job Josh. Feel sorry for the truck owner though, hope he has some recourse against the previous shop.
Modern machining has a high rate of repeatability, yet having said that would you trust your life on it? Also name and shame let them sue you, See how far they get with that!
Yes and you have the problems of scale. My rebuilds were with Volvo red-block engines of 1800 or 2000 cc displacement. Still lots going on, but much easier for a skinny kid to handle. @@AdeptApe
@@AdeptApe I rebuilt one several years ago and started it up. Had a tapping noise when I revved it up. Finally I had enough of the guy who was tapping the engine with the hammer. I went around to the other side to make him stop. Nobody was over there, I beat the "Flash" back to the key switch.
Didn’t feel like it was a long video, it was great! I love watching and learning from a true professional as someone who wrenches on my own equipment but not a professional mechanic. Thank you!
Back in my day we would loosen all the main bearing bolts slightly. This would allow a small amount of crank drop and make bearing installation easier. Good video Josh, thank you.
That doesn’t really work when the engine has one piece (circle type) front and rear main oil seals. Additionally doing that on engines with one piece (circle type) oil seals has a very good chance of damaging one or both oil seals.
Just talked with a guy that just had injector cups done and a bearing roll in done at a cat dealership . Never made it home engine started labouring , stopped to check things out , engine stalled when he disengaged clutch to stop and wouldn't turn over any more engine locked up . Had it towed back and they told him their mechanic put a rod bearing in backwards . 😮 And told him good news absolutely no damage to crank . 😅😅 I've been building cat engines for a lot of years and my question is how much Emery cloth and cocus cloth was used on crank shaft to cover their butts on that one ..lol As far as using genuine cat only parts is far over rated . Common sense tells me a core on parts means parts are being rebuilt ,and that's fine in most cases , but tell me what's better a welded reground camshaft , or a brand new quality jobber cam shaft ? Im finding a quality jobber cam lasting just as long as cat cams . Usually the cam itself is never the root problem of a bad cam in the first place . And what is better quality a head that has had cracks repaired in it , or a brand new head casting ? I've put jobber heads on C15 out on hard service jobs haven't had an issue yet , but once of many reman cat head on a C15 and could hear a slight ticking after firing it up after about 20 minutes of running the hard to hear slight ticking developed , and I found two Broken valve springs both broken at exactly same height / positioning on the coil so obviously a bad batch can show up in OEM as well I've been doing this for 40 yrs and I can honestly say with good conscience. There is good quality jobber parts and many time genuine OEM parts is just an expensive name your buying . But I will say there is some parts I insist on genuine OEM parts as well , because there is some junk jobber garbage out there . But there is also good quality jobber out there as well . So only OEM only is far over rated and myself when there is a core on cylinder liners that almost creeps me out .
You can take a cotter pin and flatten the eye. Then, stick it in an oil hole. You can roll the main in without damage. The pin falls back out on its own. That used to be an acceptable practice and was in Ford manufacture service manuals in the 1960's and 70's. I was in your line of work in the 70's and used that method. Snap-On used to make a tool that worked the same way.
Cummins actually makes a tool for rolling main bearings in, it's a brass piece that goes into the oil galley hole on the journal and will assist in rolling upper bearings in, and because it's brass it is a softer metal than the bearing and when used properly will not damage the bearing. On Cummins, there is no oil hole on the #1 main journal, though, so that one is still by hand. The part # for the Cummins tool is 3823818. This tool can be used on almost any of the Heavy Duty sized Diesel engines. It even works on smaller mid-range Cummins too.
Maybe the bearings was hard and had to be ground because he hammered numbers into the caps in a press 😂 That’s obviously where he got them out of order.
There is absolutely no excuse for not installing the main caps in proper sequence whether they are numbered or not! It is the responsibility of the mechanic to have a disciplined work methodology.
Great video. Not the most pleasurable job in the shop for sure. In top fuel that's the job of the "diver", swimming in the oil! If you take the belt off the tensioner, you get the bearing clearance more to roll in the top upper main shells. Sometimes it makes it slightly easier. It's the finer points of the repair job that seperates the parts changer's from the actual mechanics. Great quality work, keep it up!
I work in south FL on volvo heavy equipment, I'm curious who did this job. A 5 year old could have done better. Great job Josh, love the channel. Always look forward to your videos
I would have liked to do it myself, I think it would be better than what I paid for. The best of all is that I would have saved $50k+ and I'm still not done, sad but true.🤷🏻
@@geauxtigers70714I seriously doubt the owner of this truck did the butcher job on this truck because how meticulously clean as the truck is whereas whoever did the engine work had a very low amount of attention to detail comparatively.
Whats shameful and scary is that the 1st technician has been screwing over hundreds of people. A truck owner like this, only takes their baby to shops that should be trusted. This isn't ignorance we're seeing. We're seeing criminal neglect. They literally said fuck it and went to town. They knew this job was over their head. They knew they weren't doing it right. They knew this engine would likely fail sometime soon. I want to see the first mechanic called out! We don't owe them professionalism if they don't show any themselves.
I've always preferred longer videos; more educational content, especially from someone I believe is extremely competent and knowledgeable. Keep up the awesome work...and keep those long videos coming 🙂
Can’t stand a tech that takes short cuts and gives zero f’S about people’s livelihood. Great video always the right way, there is literally literature from cat.
Replacing the Rod bolts was a most excellent idea, and you explained why as well, good for you, great vid, thank you for sharing with us we all learn more together!
Great job when you showed the thrust bearing I went OMG really. When I was in the Navy I worked on Detroit’s and Fairbanks Morse. I love your Videos. Keep up the great work.
Unbelievable this truck driver spent time down to only turn around and drive to you to only have more time down, it's a tough business adding a mechanic ineptness, thank God there are professionals like you Josh great job,!!!
Him and I planned his repair out a few weeks ago and luckily we were able to get him back up on the road again in only 4 days. Not a productive 4 days for him, but at least he had it planned out and now he knows the condition his truck is in. He is a very nice guy too, bought pizza for the whole shop and was very thankful.
@@AdeptApe Good people are hard to come by these days. Your a good honest professional and that is very rare today, Happy Holidays to you and your family God bless all...
99% of truck drivers that own equipment, Don't have this extra money to throw around, Nobody seems to be talking about that. So he probably spent between 20 and 30000 dollars for the initial rebuild And then you probably charged another $5000 for your time just to go over it. And he had a nice attitude the whole time, Bought pizza, Most guys aren't in the position to do this, So I'm sure this guy probably had an extra 6 figures to play around with And the extra time of not making any money Nobody ever wants to point that out.
I've been a diesel mechanics since 1978 and i'd never seen some of the things you experienced on that motor my dad was a mechanic. Also, he taught me it's like you always said. You get what you pay for and some places will charge you. A premium price For a f minus job on workmanship or just playing on ripping. You off thank god there's people like you that are conscientious God-fearing men. God bless you and have a blessed evening.
Gotta take my hat off to the owner / operator of this unit. Amazing condition, inside and out! And credit for knowing his unit well enough, to know that something is "off" about his motor. Being a driver myself, as well as the son of a heavy duty mechanic. Cases like this, amaze, astonish, scare, and infuriate me. Shortly after the start of the tear down, had me going "WTF!" Though I am pleased to see this beautiful unit, is now in capable hands for a proper repair.
This video showed up and I just started watching and ended up watching til the end... I'm not a trucker, nor do I own a Diesel, but a lot of the procedure is the same as a gasoline... Very nice video. Thank you!
Im currently rebuilding a c15 NSX acert and i watch your videos for knowledge on how to do certain things. I've done alot of pickup diesel stuff and have alot of knowledge, but one can never have enough or should quit learning. Im fairly new to in depth heavy diesel, but enjoy it more. Long videos allow you to go into more depth on certain procedures. Thank you!!
Wow.. this is wild. We were having a discussion in the shop last week where I'm at about how bad some workmanship is out there these days. Like some of the stuff guys are okay with sending down the road is mind blowing some days..
Hi Josh, Jamie from Newcastle Australia, another very good video on our beloved C15s and no the video was not to long, I'm fairly certain everyone watching could watch you doing what your doing for hours, its very informative, please more C15 stuff, thanks for the video's they are excellent Sir, all the best from Australia🇺🇸🇭🇲🤝👍
Fantastic video. The owner 's intuition was correct. Glad it worked out. Hopefully the previous mechanic will give hime some if not all his money back.
My two cents worth. As picky about the interior of the cab, the driver/owner should be doing oil analysis, especially after major engine repairs. Oil analysis will monitor the level of different metals, (babbitt, brass, copper, bronze, etc) floating in the oil and can give early warning as to levels that are excessively out of normal range.
Your comment deserves a response. I am the owner of the truck and I am very picky inside and out. I paid for a complete repair including the head. The truck left with many problems from the beginning. And yes, I have been solving them little by little. examples (I had to change the thermostats, full of silicone I had to change all the brake housing too,they never calibrated the truck or they were incorrectly calibrated, (maybe because of the paint or dirt ,low oil code, overheating, code of all the vva valves etc. The truck went from dealer to dealer before seeing Josh. Since June I had been writing to Josh to see where he was working but making appointment with him and going from Florida to Idaho didn't bother me. It wasn’t so easy. When there and I waited almost a week just to talk to the best ,plan everything and make an appointment again in time. (believe me it was worth it, in my opinion great mechanic) cat in Florida no longer serves trucks and many dealers don't have cat specialists, it's a shame but it is what it is . $20k+ after rebuilt sound right to you,there are many things that you don't know and I can't give many details. That's my sad but true story.
@@adonisbatistaibanez4053I don't think many people can blame you for your actions honestly. You spent good money on a rebuild and as a result you expected good results. You should however consider opening a civil case against the guy who rebuilt your engine, this video is fantastic evidence in your favor
@@panzerfaus8459Even though I don't think it is always as to start a civil case easy in real life (besides it would cost more money ahead of only a chance to win and get that back as well) but of course for starters he could lay his consideration of starting such a case in front of the mechanic(s) / shop that did him wrong, maybe threatening that is sufficient to get at least part of the pay back
I work in construction as a supervisor of many jobs. I drive my truck about 65,000 miles a Year and have black stone laboratories analyze my oil about every three changes (15-18,000 miles). This has given me great insight about my engine, the oil I use and the effects of my extended oil change intervals. I pay for the better analysis
I'd be so pissed at the previous shop if I were the customer and would be shown those damages done to brand new parts which I still had to pay for.. In the end.. engineers honor.. you can't send a customer on the road like that if you value your work at all.. good thing he got to the right person who got it fixed properly, well done.
I used to work for Cat building 3600s. This video is crazy from an assembly perspective. On the washers if it’s on to cast no washer if it’s to a machined surface it gets a washer. We should all be impressed it made it nearly 2000 miles to Idaho with how poorly it was assembled.
Details make or break a job, thank you Josh for taking the time to put the video together demonstrating what was done incorrectly, I especially appreciate the way you give the benefit of the doubt to the guy "not there". Although I'm retired these days it keeps my hope alive there will be another generation of real live "mechanics", you know the how and why of what you work on, makes a huge difference in the quality of the video and the job ay hand.
I don’t think there could be an adept ape video that is too long. Look forward to these the most every week. You and Powerstroke tech talk w/a-rod haha. And watch Wes work if he comes out with a new vidya…more minutes the merrier .
Josh, I just found your channel. What a great video new subscriber here. In my younger days I used to rebuild my own engines. You just can’t start slapping an engine back together again without paying attention to the details of the stampings of the internal parts. It doesn’t matter whether it’s a little engine or big engine. I like watching, the forensic tear down of engines as well to see what killed them.
They’re getting harder to find now that everything has gone PEX, but I had an old buddy teach me to take about an 8” piece of 1/2-3/4 copper pipe and hammer one end flat, give it a little curve as well, the remaining round end makes a perfect striking surface for your ball peen hammer, this homemade tool is perfect for rolling in mains as the copper won’t scratch the hardened crank surfaces. You can get the hammered end flat on the edge providing better surface area against the edge of the bearing too. I have the same 8” piece of copper pipe in my toolbox that I made 15 years ago. Also comes in clutch when you forget your utensil for lunch.
I like the way most of the CAT techs work, always clean and by the book. Had the great opportunity of working with few folks on a 3500s and 3600s and everything was outstanding. Super clean, organized and fun!!!
I truly enjoy the longer videos, and learn so much through your methodical, and maticulous attention to detail. Your patience as well as confidence in what and how you do everything is truly wonderful. Thank you sir for anotjer amazing video.🙏💜
This is my first visit and I'm now a subscriber. Very interesting- normally bearings seem non-critical as to how they are installed. I now know differently.
i was a diesel roadside mechanic i could do the hydraulics, air system, brakes and pretty much anything out side of internal engine but i join the uscg and went the mechanic route finally got to rebuild a 2 stroke Detroit in A school. ive learned so much on attention to detail i.e matching numbers like on bearing caps and con rods. small things can cause big issues but i cant wait to get out to possibly start a shop. love the video
Ah, the Florida swindle…as common as cock roaches down here. I’m a Florida trucker and have found the same kind of swindle here, but not quite as severe as this one. There is a saying here as old as the state itself. “ The pirates that discovered Florida centuries ago never left. They are alive and well living in spirit in their great, great, great, grandchildren still living here”.
Thanks for taking the time and your company allowing you to film this great content. I’m in texas and hopefully I can bring my motor to you for an overhaul. I have a c-15 6nz with less than 800k and starting to get done good blow by.
I used the tiniest brass punch I had to roll mine out. I also used the pocket screwdriver, but only to realign the new top bearings when they started to go a bit sideways.
I stumbled on your channel and instantly gained respect. It’s so rare anymore that ‘mechanics’ take the time to do repairs correctly, most videos simply show how to do it either faster or cheaper. A few I’ve found that appear to do it right aren’t the cleanest ‘mechanics’ I’ve ever seen. I keep ‘marking’ the term mechanic because there are so few left. Most are technicians that throw parts at a problem, very few are thorough with each step, hence I’m reluctant to call them ‘mechanics’ It was a pleasure to watch you work, as you face credit where credit was due, but also spoke the truth when needed. (in other words, you were kind with your critiques) It’s was nice to see a real, old school mechanic at work.
Anyone on here know anyone like this guy except for ISX Cummins instead of Cat? Love this guys passion to do the job right and I learn a lot by what he says. I own ISX cummins though and would love to find a channel for those. Thank yall
My C-15 "6NZ" also drops oil pressure just slightly under full load. It always has. 2-3 PSI if I had to guess. I just choked that up to being normal and it makes sense to me when you think about what's going on inside of the engine. I'd say as long as the oil pressure is within CAT spec, I see no reason to worry about it. Great video Josh, thanks for sharing with us! Long or short, I watch them all and love learning from you.
After watching this video and cruising my Freightliner down the highway you never notice the oil pressure drop as the power and boost come on fairly slow but if I'm in a hard pull and let off the oil gauge jumps that 2.5 psi, funny how all my years of driving and I never noticed that, learn something every day, I'm personally not going to worry about it at this point
Great vid Josh! Loved how you showed all the steps and very detailed. I prefer this kind of vid besides the shorter ones where you edit to make them shorter. I'd love to see more vids with some 3/4" or 1" impact action!
Some of the nastiest, skunkiest, oil that you will ever find! I have to change my shirt after it soaks through. It will stain your skin for a week too!
Those grooves in the crank are the reason for oil pressure loss, unfortunately. But you done all you could without removing the entire assembly and machining or replacing the crank. Damn good, top notch professional repair. If all shops and the technicians who work there were this good these videos wouldnt even exist. Thanks again man. Just subbed, liked and commented. 4 or 5 times, not sure exactly,but had much to say😊
Cat makes a tool to remove/install the upper main bearings. It's a round pin that slips in the crank oil hole and has a little hinged flat bar attached to the end. Slip it in, roll the crank around, and it pushes the bearing in/out. Worked good on my old 3306. Found the p/n... 2p-5518
I have a small bolt with the head ground down that performs the same function. Made it in Mexico and down there they called it the campeón (champion) 😂

Just push pause and come back to it later.

Grinding the bearings... My heart's breaking for that poor customer.
This video is really going to help this guy in civil court. Its a tough hit financially
Can he sue? It would be amazing if he could recoup the loss because from what I hear, the maintenance cost of these engines is expensive.
@JuniorJunison u can 100% sue
Plat rebuild from cat on a c15 is 33k out the door ( i just paid it)

The first rebuild was also uploaded to TH-cam. I saw it being rebuilt in India on a dirt floor.
They would probably do a better job to be honest
Sadly I think those Indians would have done better. Not perfect, but better. This is horrible work.
Wow that last guy beat those bearings like a red headed step child! Great job unassing that job Josh!!
Didn’t feel like it was a long video, it was great! I love watching and learning from a true professional as someone who wrenches on my own equipment but not a professional mechanic. Thank you!
Its a miracle it got there under its own power.
As someone who builds a lot of engines I literally and aggravated watching this, this is insane but happens all the time…
You could make every video 1hr we would still watch them all
Yep definitely agree.
True
I would watch any actual authority on something no matter how long. Keep up the great work sir.
Wow! This guy really got taken. Thanks for being a great mechanic and also for a awesome video..
nice save boss! buddy who slammed that minty ol cat together was all the stunned! hahaha
I wonder if the mechanic will watch it, who knows.
@@AdeptApe So Florida ? truck repair Anything and I mean anything goes !
Reminds me of that commercial." You can pay me now ,....or you can pay me later"
Love your videos .Glad to see you put the music back in them.
Back in my day we would loosen all the main bearing bolts slightly. This would allow a small amount of crank drop and make bearing installation easier.
Good video Josh, thank you.
That's also how I do it.
That doesn’t really work when the engine has one piece (circle type) front and rear main oil seals. Additionally doing that on engines with one piece (circle type) oil seals has a very good chance of damaging one or both oil seals.
Just talked with a guy that just had injector cups done and a bearing roll in done at a cat dealership . Never made it home engine started labouring , stopped to check things out , engine stalled when he disengaged clutch to stop and wouldn't turn over any more engine locked up . Had it towed back and they told him their mechanic put a rod bearing in backwards . 😮 And told him good news absolutely no damage to crank . 😅😅 I've been building cat engines for a lot of years and my question is how much Emery cloth and cocus cloth was used on crank shaft to cover their butts on that one ..lol
As far as using genuine cat only parts is far over rated . Common sense tells me a core on parts means parts are being rebuilt ,and that's fine in most cases , but tell me what's better a welded reground camshaft , or a brand new quality jobber cam shaft ? Im finding a quality jobber cam lasting just as long as cat cams . Usually the cam itself is never the root problem of a bad cam in the first place . And what is better quality a head that has had cracks repaired in it , or a brand new head casting ? I've put jobber heads on C15 out on hard service jobs haven't had an issue yet , but once of many reman cat head on a C15 and could hear a slight ticking after firing it up after about 20 minutes of running the hard to hear slight ticking developed , and I found two Broken valve springs both broken at exactly same height / positioning on the coil so obviously a bad batch can show up in OEM as well I've been doing this for 40 yrs and I can honestly say with good conscience. There is good quality jobber parts and many time genuine OEM parts is just an expensive name your buying . But I will say there is some parts I insist on genuine OEM parts as well , because there is some junk jobber garbage out there . But there is also good quality jobber out there as well . So only OEM only is far over rated and myself when there is a core on cylinder liners that almost creeps me out .
You can take a cotter pin and flatten the eye. Then, stick it in an oil hole. You can roll the main in without damage. The pin falls back out on its own. That used to be an acceptable practice and was in Ford manufacture service manuals in the 1960's and 70's. I was in your line of work in the 70's and used that method. Snap-On used to make a tool that worked the same way.
Not all main journals have an oil gallery to use the guide tool with, I always push on the tang on those
In the book for a Cummins ISM they suggest that method. After I read that I was amazed and always do it that way so much easier!
Cummins actually makes a tool for rolling main bearings in, it's a brass piece that goes into the oil galley hole on the journal and will assist in rolling upper bearings in, and because it's brass it is a softer metal than the bearing and when used properly will not damage the bearing. On Cummins, there is no oil hole on the #1 main journal, though, so that one is still by hand. The part # for the Cummins tool is 3823818. This tool can be used on almost any of the Heavy Duty sized Diesel engines. It even works on smaller mid-range Cummins too.
Cat makes a tool for that. I have one
Always used a new unused brass brake shoe rivet to roll main bearings. Fit perfectly in the crankshaft oil hole.
Video was NOT too long. Thoroughly enjoyed it.
Those stamps were either done by an old timer who is really good at it, or some type of press. Love watching you work and hearing your knowledge.
Not by the same kind of person who puts together an engine this way
Maybe the bearings was hard and had to be ground because he hammered numbers into the caps in a press 😂
That’s obviously where he got them out of order.
There is absolutely no excuse for not installing the main caps in proper sequence whether they are numbered or not! It is the responsibility of the mechanic to have a disciplined work methodology.
Great video. Not the most pleasurable job in the shop for sure. In top fuel that's the job of the "diver", swimming in the oil! If you take the belt off the tensioner, you get the bearing clearance more to roll in the top upper main shells. Sometimes it makes it slightly easier. It's the finer points of the repair job that seperates the parts changer's from the actual mechanics. Great quality work, keep it up!
Great repair job! You saved him from having to pull the crank out and replace it adding to the costs.
I work in south FL on volvo heavy equipment, I'm curious who did this job. A 5 year old could have done better.
Great job Josh, love the channel. Always look forward to your videos
This has owner operator finger prints all over it guy who owns a truck as meticulous as that is doing his own rebuild
@@geauxtigers70714I would think that a guy that keeps a truck as nice as that wouldn't screw himself on an engine job.
@@geauxtigers70714 I thought the same.
I would have liked to do it myself, I think it would be better than what I paid for. The best of all is that I would have saved $50k+ and I'm still not done, sad but true.🤷🏻
@@geauxtigers70714I seriously doubt the owner of this truck did the butcher job on this truck because how meticulously clean as the truck is whereas whoever did the engine work had a very low amount of attention to detail comparatively.
Whats shameful and scary is that the 1st technician has been screwing over hundreds of people. A truck owner like this, only takes their baby to shops that should be trusted. This isn't ignorance we're seeing. We're seeing criminal neglect. They literally said fuck it and went to town. They knew this job was over their head. They knew they weren't doing it right. They knew this engine would likely fail sometime soon. I want to see the first mechanic called out! We don't owe them professionalism if they don't show any themselves.
I've always preferred longer videos; more educational content, especially from someone I believe is extremely competent and knowledgeable. Keep up the awesome work...and keep those long videos coming 🙂
The longer the format the better. The more we get to learn and understand. Thanks for the great video.
Can’t stand a tech that takes short cuts and gives zero f’S about people’s livelihood. Great video always the right way, there is literally literature from cat.
Replacing the Rod bolts was a most excellent idea, and you explained why as well, good for you, great vid, thank you for sharing with us we all learn more together!
This video is telling the story about what NOT to do and how to fix someone’s life choices. Thanks Josh. Excellent as always.
Great job when you showed the thrust bearing I went OMG really. When I was in the Navy I worked on Detroit’s and Fairbanks Morse. I love your Videos.
Keep up the great work.
Unbelievable this truck driver spent time down to only turn around and drive to you to only have more time down, it's a tough business adding a mechanic ineptness, thank God there are professionals like you Josh great job,!!!
Him and I planned his repair out a few weeks ago and luckily we were able to get him back up on the road again in only 4 days. Not a productive 4 days for him, but at least he had it planned out and now he knows the condition his truck is in. He is a very nice guy too, bought pizza for the whole shop and was very thankful.
@@AdeptApe Good people are hard to come by these days. Your a good honest professional and that is very rare today, Happy Holidays to you and your family God bless all...
99% of truck drivers that own equipment, Don't have this extra money to throw around, Nobody seems to be talking about that.
So he probably spent between 20 and 30000 dollars for the initial rebuild
And then you probably charged another $5000 for your time just to go over it.
And he had a nice attitude the whole time, Bought pizza,
Most guys aren't in the position to do this, So I'm sure this guy probably had an extra 6 figures to play around with
And the extra time of not making any money
Nobody ever wants to point that out.
Thank you for taking care of this truck. Practically a miracle it didn't develop knock
The longer the better more information is always good in my opinion at least.
As a former trucker this channel brings back good memories. I ran the same truck and the 3406 cat 425 . thank you.
I've been a diesel mechanics since 1978 and i'd never seen some of the things you experienced on that motor my dad was a mechanic. Also, he taught me it's like you always said. You get what you pay for and some places will charge you. A premium price For a f minus job on workmanship or just playing on ripping. You off thank god there's people like you that are conscientious God-fearing men. God bless you and have a blessed evening.
The owner sure does a great job keeping it clean, got to respect a man that takes excellent care of his equipment.
Appreciate you work on youtube your professionalism harkens to a bygone era which is sadly missing in todays business culture.
Gotta take my hat off to the owner / operator of this unit.
Amazing condition, inside and out!
And credit for knowing his unit well enough, to know that something is "off" about his motor.
Being a driver myself, as well as the son of a heavy duty mechanic. Cases like this, amaze, astonish, scare, and infuriate me.
Shortly after the start of the tear down, had me going "WTF!"
Though I am pleased to see this beautiful unit, is now in capable hands for a proper repair.
Thats huge respect if the guy drove that long distance to have you wrench on his rig joshua.
Keep it real bro
This video showed up and I just started watching and ended up watching til the end... I'm not a trucker, nor do I own a Diesel, but a lot of the procedure is the same as a gasoline... Very nice video. Thank you!
Im currently rebuilding a c15 NSX acert and i watch your videos for knowledge on how to do certain things. I've done alot of pickup diesel stuff and have alot of knowledge, but one can never have enough or should quit learning. Im fairly new to in depth heavy diesel, but enjoy it more.
Long videos allow you to go into more depth on certain procedures.
Thank you!!
The commentary is so good. It almost sounds like a voiceover!! Awesome video!
it is voiceover. he use two audio clip stacked.
Wow.. this is wild. We were having a discussion in the shop last week where I'm at about how bad some workmanship is out there these days. Like some of the stuff guys are okay with sending down the road is mind blowing some days..
Its a miracle that it made it to you under its own power.
Hi Josh, Jamie from Newcastle Australia, another very good video on our beloved C15s and no the video was not to long, I'm fairly certain everyone watching could watch you doing what your doing for hours, its very informative, please more C15 stuff, thanks for the video's they are excellent Sir, all the best from Australia🇺🇸🇭🇲🤝👍
I like the longer detailed videos !
Great job , so much to learn
Thank you
Fantastic video. The owner 's intuition was correct. Glad it worked out. Hopefully the previous mechanic will give hime some if not all his money back.
In this case I’m pretty sure the court is going to make the mechanic give a full refund. That job was not done right.
Anyone who assembles an engine like that isn’t going to cover any costs “willingly”.
@@markm0000not only the cost of the job, the legal fees too he'll be broke after that
Its amazing how he drove the truck from Florida to Idaho
My two cents worth. As picky about the interior of the cab, the driver/owner should be doing oil analysis, especially after major engine repairs. Oil analysis will monitor the level of different metals, (babbitt, brass, copper, bronze, etc) floating in the oil and can give early warning as to levels that are excessively out of normal range.
Your comment deserves a response. I am the owner of the truck and I am very picky inside and out. I paid for a complete repair including the head. The truck left with many problems from the beginning. And yes, I have been solving them little by little. examples (I had to change the thermostats, full of silicone I had to change all the brake housing too,they never calibrated the truck or they were incorrectly calibrated, (maybe because of the paint or dirt ,low oil code, overheating, code of all the vva valves etc. The truck went from dealer to dealer before seeing Josh. Since June I had been writing to Josh to see where he was working but making appointment with him and going from Florida to Idaho didn't bother me. It wasn’t so easy. When there and I waited almost a week just to talk to the best ,plan everything and make an appointment again in time. (believe me it was worth it, in my opinion great mechanic) cat in Florida no longer serves trucks and many dealers don't have cat specialists, it's a shame but it is what it is . $20k+ after rebuilt sound right to you,there are many things that you don't know and I can't give many details. That's my sad but true story.
@@adonisbatistaibanez4053I don't think many people can blame you for your actions honestly. You spent good money on a rebuild and as a result you expected good results. You should however consider opening a civil case against the guy who rebuilt your engine, this video is fantastic evidence in your favor
I feel for you the thoughts and doubts when you were finding out these problems would drive some to drink.@@adonisbatistaibanez4053
@@panzerfaus8459Even though I don't think it is always as to start a civil case easy in real life (besides it would cost more money ahead of only a chance to win and get that back as well) but of course for starters he could lay his consideration of starting such a case in front of the mechanic(s) / shop that did him wrong, maybe threatening that is sufficient to get at least part of the pay back
I work in construction as a supervisor of many jobs. I drive my truck about 65,000 miles a Year and have black stone laboratories analyze my oil about every three changes (15-18,000 miles). This has given me great insight about my engine, the oil I use and the effects of my extended oil change intervals. I pay for the better analysis
Enjoy watching your videos no matter how long it is. Thanks for sharing 👍🏽.
I'd be so pissed at the previous shop if I were the customer and would be shown those damages done to brand new parts which I still had to pay for.. In the end.. engineers honor.. you can't send a customer on the road like that if you value your work at all.. good thing he got to the right person who got it fixed properly, well done.
I used to work for Cat building 3600s. This video is crazy from an assembly perspective. On the washers if it’s on to cast no washer if it’s to a machined surface it gets a washer. We should all be impressed it made it nearly 2000 miles to Idaho with how poorly it was assembled.
Details make or break a job, thank you Josh for taking the time to put the video together demonstrating what was done incorrectly, I especially appreciate the way you give the benefit of the doubt to the guy "not there".
Although I'm retired these days it keeps my hope alive there will be another generation of real live "mechanics", you know the how and why of what you work on, makes a huge difference in the quality of the video and the job ay hand.
I made it to 13 minutes before I felt like throwing up. That is disgusting work. Glad it's now in the hands of a competent mechanic.
I don’t think there could be an adept ape video that is too long. Look forward to these the most every week. You and Powerstroke tech talk w/a-rod haha. And watch Wes work if he comes out with a new vidya…more minutes the merrier .
I enjoy long format videos. Theyre great to listen to when working and the depth of knowledge shared is valuable.
Josh, I just found your channel. What a great video new subscriber here. In my younger days I used to rebuild my own engines. You just can’t start slapping an engine back together again without paying attention to the details of the stampings of the internal parts. It doesn’t matter whether it’s a little engine or big engine. I like watching, the forensic tear down of engines as well to see what killed them.
Dawg I learned how to fix my diesel engines after watching this channel. love your first person view of these repair and inspections.
They’re getting harder to find now that everything has gone PEX, but I had an old buddy teach me to take about an 8” piece of 1/2-3/4 copper pipe and hammer one end flat, give it a little curve as well, the remaining round end makes a perfect striking surface for your ball peen hammer, this homemade tool is perfect for rolling in mains as the copper won’t scratch the hardened crank surfaces. You can get the hammered end flat on the edge providing better surface area against the edge of the bearing too. I have the same 8” piece of copper pipe in my toolbox that I made 15 years ago. Also comes in clutch when you forget your utensil for lunch.
Well done you saved that truck driver alot of money and you saved the engine !! all the best from the uk
I like the way most of the CAT techs work, always clean and by the book. Had the great opportunity of working with few folks on a 3500s and 3600s and everything was outstanding. Super clean, organized and fun!!!
Yeah Bro...Honesty is key in this trade...good job
I truly enjoy the longer videos, and learn so much through your methodical, and maticulous attention to detail. Your patience as well as confidence in what and how you do everything is truly wonderful. Thank you sir for anotjer amazing video.🙏💜
This is my first visit and I'm now a subscriber. Very interesting- normally bearings seem non-critical as to how they are installed. I now know differently.
To help get the uppers set, I’ve been using a poly trim tool, it’s basically very hard to break plastic mini crowbar.
i was a diesel roadside mechanic i could do the hydraulics, air system, brakes and pretty much anything out side of internal engine but i join the uscg and went the mechanic route finally got to rebuild a 2 stroke Detroit in A school. ive learned so much on attention to detail i.e matching numbers like on bearing caps and con rods. small things can cause big issues but i cant wait to get out to possibly start a shop. love the video
🙏🏻USCG🏁
Ah, the Florida swindle…as common as cock roaches down here. I’m a Florida trucker and have found the same kind of swindle here, but not quite as severe as this one.
There is a saying here as old as the state itself. “ The pirates that discovered Florida centuries ago never left. They are alive and well living in spirit in their great, great, great, grandchildren still living here”.
First thing came to my mind.
Anyone would be money ahead to be towed out of that area and get the work done somewhere else.
I moved to Florida for a year got fired from a job because I wouldn't do crap work and swindle customers.
What a great job and so clear video
Thanks for taking the time and your company allowing you to film this great content. I’m in texas and hopefully I can bring my motor to you for an overhaul. I have a c-15 6nz with less than 800k and starting to get done good blow by.
Dude, you have many miles left in that engine. You're only a little over half way to an overhaul.
Barely run in.😇@@boogieman3165
Thanks for letting me tag along. Making videos is a lot of extra work for you, I am grateful.
When I rebuilt my old 3406 cat I used a flexible scraper to push the upper mains out and it worked great
I used the tiniest brass punch I had to roll mine out. I also used the pocket screwdriver, but only to realign the new top bearings when they started to go a bit sideways.
Think of it this way, this guy has rebuilt other motors too. Gives me the shivers!
Josh I've had trouble rolling in upper main bearings in the past and found that loosening the fan belts helps quite considerably.
Yes it is very good to loosen fan belts, it helps !!👍👍
I stumbled on your channel and instantly gained respect. It’s so rare anymore that ‘mechanics’ take the time to do repairs correctly, most videos simply show how to do it either faster or cheaper. A few I’ve found that appear to do it right aren’t the cleanest ‘mechanics’ I’ve ever seen.
I keep ‘marking’ the term mechanic because there are so few left. Most are technicians that throw parts at a problem, very few are thorough with each step, hence I’m reluctant to call them ‘mechanics’
It was a pleasure to watch you work, as you face credit where credit was due, but also spoke the truth when needed. (in other words, you were kind with your critiques)
It’s was nice to see a real, old school mechanic at work.
Love your videos Josh long or short. Keep up the right way to build engines.
Anyone on here know anyone like this guy except for ISX Cummins instead of Cat? Love this guys passion to do the job right and I learn a lot by what he says. I own ISX cummins though and would love to find a channel for those. Thank yall
Looks like a lot of rookie mistakes and that's putting it politely. That's a very nice KW great job as always
love the long form format. This is probably the best sales video for your shop on TH-cam!!! Fantastic Work!!!!
This is amazing video thanks Josh.
We had a n14 that had to be "re rebuilt" 4 time because of shady work like this.
Love the longer in shop vid! I enjoy the story that goes along with the job
The video was absolutely great and very informative. Very professionally done.
My C-15 "6NZ" also drops oil pressure just slightly under full load. It always has. 2-3 PSI if I had to guess. I just choked that up to being normal and it makes sense to me when you think about what's going on inside of the engine. I'd say as long as the oil pressure is within CAT spec, I see no reason to worry about it. Great video Josh, thanks for sharing with us! Long or short, I watch them all and love learning from you.
After watching this video and cruising my Freightliner down the highway you never notice the oil pressure drop as the power and boost come on fairly slow but if I'm in a hard pull and let off the oil gauge jumps that 2.5 psi, funny how all my years of driving and I never noticed that, learn something every day, I'm personally not going to worry about it at this point
Lucky he didn't lose the crankshaft
I am really liking the video. Thanks for being very descriptive.
Great vid Josh! Loved how you showed all the steps and very detailed. I prefer this kind of vid besides the shorter ones where you edit to make them shorter. I'd love to see more vids with some 3/4" or 1" impact action!
Nothing wrong with a long video. A person can always skip ahead if they want. Lots of good info here. Thanks for the knowledge!
There is a unique aroma associated with main bolts
Some of the nastiest, skunkiest, oil that you will ever find! I have to change my shirt after it soaks through. It will stain your skin for a week too!
Great to watch someone who takes pride in his work
Those grooves in the crank are the reason for oil pressure loss, unfortunately. But you done all you could without removing the entire assembly and machining or replacing the crank. Damn good, top notch professional repair. If all shops and the technicians who work there were this good these videos wouldnt even exist. Thanks again man. Just subbed, liked and commented. 4 or 5 times, not sure exactly,but had much to say😊
I’d love to see more long videos like this!! You have no idea how much knowledge this has given me! Love your videos brother!
Cat makes a tool to remove/install the upper main bearings. It's a round pin that slips in the crank oil hole and has a little hinged flat bar attached to the end. Slip it in, roll the crank around, and it pushes the bearing in/out. Worked good on my old 3306. Found the p/n... 2p-5518
I have a small bolt with the head ground down that performs the same function. Made it in Mexico and down there they called it the campeón (champion) 😂
Still have mine!!
