Was on the side of road got out to fix my load then when I got back truck wouldn’t turn on, I figured something with fuel since it cranked but no start, so got on TH-cam to see and followed this video, swapped it and now we are running! Thanks to God!!! The old owner had a spare part and n the truck 🙏
Very informative! I think I just found my low power problem! Thanks bud 👍🏼
Always enjoy the videos. Thanks Josh,
Your the diesel guru
Another great video from my favorite diesel TH-camr
Thanks, Josh. Just what I was looking for. Please keep up the great work on your channel.
I like this channel too much
Carry on sir
Wish more success for you
Great video as always
Thanks for the videoes you are a great mechanic
I imagine finding OTR trucks with CAT motors are becoming rare these days since CAT stopped making engines for OTR trucks for awhile now. Plus, with all these new emission standards.
They aren't rare yet, Cat made a lot of engines for a lot of years and many people don't want to get the heavily emission restricted engines. Of course there are a few less of them every year on the road, so sooner or later there won't be many.
@@AdeptApe I heard they are making a new c-13 Is that true ?
Still doing a great video. Had watched your videos in a few months. Medicineman 10-4 but I retired from trucking. But still got the old Percculator. 99 w9
Quick question I’m a mechanic in the marine corps I work on these engines all the time and just did a transfer pump the other day on a c-12, I’m curious as to why mine has a gasket but no O-Ring, seems a bit odd because just looking at it seems like it would require an O-Ring such as the steering pump which is directly behind it on our engines. Either way it’s a CAT gasket and ended up doing the trick. And also on all our c-12s there isn’t 12 point bolts they are Allen keys which is a pain in the ass to get in there, same as the steering pump.
Thanks, you the man . Help a lot with my problems.
Before removing the pump is there a shutoff valve on the main fuel line to keep the tanks from emptying when the line is removed? I have C13 that Im doing a transfer pump on. I don't see any valve on the engine side so kind of curious what keeps the fuel in the tanks ones those fuel lines are removed.
Thanks for the videos!!
I have a question for you to see if you have any answer, I have a cat c15 with conversion to a single turbo PDI. Every morning I have to drain the first oil filter a bit because if the truck doesn't have power, the turbo doesn't go up to 25, after I do this it usually goes up to 45 and on many occasions when I'm going up a slope it happens the same the force ends and the turbo lowers the pressure to 25, I have already changed the oil pump but the problem continues, if you could give me an answer it would be of great help. Thank you
If i run my c15 with a bad oil ring for the fuel pump..can that cause any other problems besides it leaking oil and making a mess
I put a new pump on and now I'm getting a whine and high pitch vibration hrough my fuel pressure gauge line that runs into the cab. Could this be a faulty new fuel pump?
So I mn having fuel filter vacuum issues if I changed the pump would that help that or is there something else I should check out?
What should the fuel pressure be on a 3306b
Cant you jus stretch the spring in the relief valve and in the housing and get increased fuel pressure also?..thats if of course your trucks fuel pump in working properly?
I'm curious if the C-10 transfer pump needs the upgraded spring, thx in advance.
Awesome, thanks!! Help a lot
Thank you sir
Question, does a new pump come with updated spring?
Adept, my troke broke down coming off the highway(C15 3406 engine). The ignition wire on the breaker corroded and broke off. I had the vehicle towed about 3 miles out of traffic but the truck was left in gear while being towed. I replaced the breaker and was able to get the truck to crank but now it wont get fuel in the lines. As if the pump isn't working. I have refilled the filter and prime the pump on the filter. I have used some starting fluid but once the filter runs out of disel it shuts off. Could the tow in gear ruin the fuel/transfer pump
What was the remedy?
Nice video.
with all respect thanks for great teaching
I have these symptoms, but why would the truck de rate itself? I have a 1991 so there are no fault codes
Helpful thanks
I can't tell you , how you helped me but you are great, okay I will share my stupidity I was shiming pump and plunger fall down after 2 hours priming scratching ☄️ I found plunger fall out with spring , now I don't know how to insert means which side goes first and at 3:20 you shared picture , wallah!!!! You are great guy...
Glad I could help by accident.
Nice👍
Hey Bro. I'm from guyana I have a c12 engine in a foden it does break injector. what can I do about it?
A theory on that radiator. If it is only degrading on the engine side it may be caused by debris striking the fins. Gets to be like a sand blaster inside the fan shroud area, especially for ag and construction operations.
Where are you getting that, out of curiosity?
lee c13. truck always starts perfect. runs good till it's ran for 1/2 hour or so. going over 55 mph for 10 min or so, the truck starts to miss and lose power. we are running 85 psi fuel pressure. the needle bounces a bit and it is a fluid filled gauge. we have done everything we know of. all new lines. new primer valve. we finally installed a clear hose on the suction side. it starts perfect. runs perfect. until heavy loads and all the way warm. when we shut the truck off, the clear tube sucks and fills with air from the line going to the transfer pump. where do you think this air is coming from? it does not come from the tank. is it possible the seal in the transfer pump will allow vacuum when not operating to allow air to enter back into the return line?
Adept Ape I’m having a hell of a time trying to get my pump with the new gasket to seat flush so that I can bolt it down. Is there some trick to this? Gasket seems a little too thick.
Oring most of the time.
Man I got no fuel coming to the first filter but second one has fuel what gives got plenty of fuel in tanks I replaced the second hose going from the first filter to pump please help
I would like to know if you recommend the conversion on cat c15 from twin turbo to single turbo ???
Idk what adept would say but....I have a friend with a 6nz single turbo and an accert c15 with duals. Both are hot rodded to the hilt. Regardless of the hot rodding...no matter what has been done to both trucks....the accert pyro stays several hundred degrees lower than the 6nz single turbo and always out pulls it. The accert has stock dual turbos and the 6nz has has big dog turbo...pdi....etc...and now a Blalock. My friend swears to god he will never buy anything else but an accert twin motor truck. Of course...the accert cylinder decompression system is disabled and so those accert failures are void. I drive both trucks every week...back to back. The accert always wins on power and pyro temps. One trick is to lower the compression on the accert to 16:1 pistons (from factory 18:1). They learned this the hard way with failure over and over.... the 16:1 pistons with accert delete was the winning ticket.
Also that was a reman part for around $185.00 bucks with out core charge. New ones are around $265.00. Don't forget the new O-ring $6.00. Both new and reman come with 1yr warranty I was told!👍
Got a part number for that o ring? I ordered a new pump from cat today for 300 even
@@marioq3792 Sorry I don't have that part number for the O-ring but they know which one you will need to match up with the pump. WoW, you paid $300.00 for a new one? Phew that's steep! The Cat dealership where I bought my pump was salivating for some reason over my original pump and they were like, yeah man please make sure you bring your core back! But I kept it because it's the original and I'll get it rebuilt at Turbo here in Atlanta. It was a really well made pump from 1995 and I can get them to increase the flow. Plus it really looks good on the front of the motor like when you see a yellow Cat air compressor with the red tag, it just looks right hanging on the side of the Big Kitty. But that yellow pump is pricey...lol. Long live the Large Cars🤟
I have a question for you to see if you have any answers, I have a cat c15 with PDI single turbo conversion. Every morning I have to empty the first fuel filter a little because if the truck does not have power the turbo does not go up to 25, after doing this it usually goes up to 45 and on many occasions when I go up a hill the force passes the same and The turbo lowers the pressure to 25, I have already changed the fuel pump but the problem remains, if you could give me an answer it would be helpful. Thank you
Did you ever find out what the problem was?
Adept Ape i get fine metal filings in my fuel filter,also truck is not getting enough power and boost 16psi max on c12,please help
I’m having that issue now but the mechanic is saying that the fuel transfer is working . So what else should we check?
Funny u posted this.
I just inspected a truck I wanted to buy and rebuild.
2004 w900 with a c15. Had a engine fire due to leaky fuel filter housing squirting fuel and started a engine fire.
Seller changed all electrical lines and decided to forget to mention the engine fire. But didn’t bother to clean all the burn marks on the engine.
I asked why the engine stickers were burned off and what’s all the black stuff on the engine.
He said the head was charged and they used a junk yard head and didn’t clean it. Lol
I couldn’t make this shit up if I tried.
See the pics for yourself.
It’s a blue 2004 w900 being sold by a dealer in Ogden Utah for 24999$.
Some people don’t think your stupid but if u are they sure don’t wanna miss you. So they will try anything to make a sale.
I'd estimate the fire was started by something other than a fuel leak. I've had a line crack spraying fuel directly on the exhaust manifold. Lots of white smoke, but uneventful otherwise. Electrical short on the other hand... those will take out equipment in short order. Sounds like the truck owner wasn't much for maintenance in the first place, so getting a straight answer is probably not happening.
truck was running good before fueling at a road ranger gas station. after fueling about 30-45 mins later I started loosing power. so when I got home changed both fuel filters and air filters. but today still same problem. cant go over 55mph when loaded and in uphills it struggles and starts slowing down any help? it's a CAT C15 6NZ model
Hi, Leo
What ended up being the issue for you ?
I’m having the same exact problem as you …
I got fuel at Road Ranger and ever since then the truck has had a lack of power and won’t
Go over 55mph. Already spent over $2,000 at the shop and they can’t figure it out.
I got a Cat C15 MBN Engine. Please let me know.
How do you determine whether to replace the spring kit or the entire pump? I changed the regulator in the filter base but the truck still doesn't seem right. When I use the hand pump I can hear a clicking in the transfer pump. Is that normal? I need to find a gauge instead of guessing.
Need to check PSI under load. Spring kit only works on the newer pumps. Pumps do have a check valve in them. I have stretched the spring to compensate for wear. Again you need a gauge to make sure what you did is correct.
@@johngoldsmith6629 thank you for your reply. I agree i need to put a gauge on it. I installed the spring kit and it was almost an inch longer than the old spring. So far it seems to run a little better.
3:19 is there a upgrade spring kit for a 2006 C13 “KCB38042”? My local CAT has no idea about this spring kit.
Hey Josh,
I have a 2005 C15 BXS that sometimes just takes off like a shotgun, however, after sitting for, say, maybe a week or more, it just cranks and cranks forever before it finally fires. Could that be my fuel lift pump, or is something else causing all the fuel to drain back into the tank?
Thanks In Advance.
More than likely your fuel is running out of the cylinder head. Can leak onto the piston. Which when you start, cranks up and dies. Black smoke out the exhaust as it burns this fuel off. Or leaking out supply or return. You can replaced the 75LB regulator. Make sure you torque it. It will distort and change psi. I put a one way flow check after base. Take fitting out and install it, reinstall fitting and hook hose back up. If on supply side you can make a P-trap in line to prevent fuel from draining back from fuel transfer pump. You can also put a one way flow check in supply side. I like to put my check at splitter. So fuel is trapped all the way to fuel transfer pump. You could put a check on each supply line at tank.
If you have the tooling you need to install sight glasses at return hose before 75 regulator. Between cylinder head and secondary fuel filter. Another one between primary fuel filter and fuel transfer pump. See which one(s) go empty after setting. If it's leaking on the piston you have to pull exhaust manifold. Plug turbo oil psi line and let it set. Usually the next day or so have someone start engine and see which cylinder has the black smoke out the exhaust.
@@johngoldsmith6629
Thank you very much for your reply. I forgot to mention in my original question that intermittantly at low idle, the engine sounds lopey, but when I speed the RPM up to 1000 with the cruise, it seems to go away. Engine is in a 2005 Kenworth T800.
Libertarian Philosophy Have you done a cylinder cut out test?
@@johngoldsmith6629
No. I don't have any electronic service tools for Cat engines. Owner operator unit.
Libertarian Philosophy I would check fuel psi, air in the return and a cylinder cut out test. Two types of cut out test. The four cylinder Cat has. And the one I came up with, data log RPM's. Set to 2120, no fan, no A/C, air compressor not pumping, operating temp. Cut five cylinders out let it run one minute and go to two, kill one and so forth until all are completed. Should have 8 data points to look at. First and last all cylinders firing, middle each cylinder. Looking for balance that cylinders are holding about the same RPM's.
My interview with CAT for ThinkBIG is on Monday the 18th any tips?
and love destruction of the week.
brian hoffman all the best mate
Showing a positive attitude and strong willingness to learn is key.
thanks @HAMM3R and @Muchie

CAT motor question not on a vehicle, but rather an CAT motor used to turn a large irrigation motor.
Between the motor and the top of the aboveground fuel tank the owner has plumbed in a ball valve. Mechanic installed newly rebuild fuel transfer pump.
System ran for a minute, then it stopped. Mechanic traced the return line and found the return line ball valve in the closed position. If the diesel return line is capped what would happen? Would the gears in the pump break, the pressure regulator spring break, or would the system flood out because there was no where for the fuel to go?
Can you please a part # for that fuel line adapter that you used to check for a fuel supply? Thank you
Did U find it? I need it too!
Can diesel get in your oil due to bad pump.?
I have a new pump p/n388-7286 . The pump calls for p/n 316-6865. The pump is pumping in the wrong direction is this possible or am I missing something. C12 s/n 2ks75456. The engine turns clockwise (standing front of engine)I hooked the pump to my power drill and it seams to go the wrong way. I have a video I would share tks
Hey Ape i have a 98 pete 379 with a Cat c12. i have a small issue with the engine fan, the fan won't automatically come on at all. Check engine light comes on due to high coolant temperature. The fan light on dash is constantly on (which apparently should come on when i manually switch the fan into manual mode). The fan does engage when i switch it on manually. It started all this when i took the fan blade off and installed a A/C compressor belt but at the same time i replaced the oil temp gauge. Checked all the wires from ECM to cab and they all in good condition. please help. thank you and thank you for posting all these GREAT videos!
Sounds like you have a OEM problem. First who is driving the fan, Pete or Cat? If Cat you need a test light know which wire is coming out of the J1 connector. Use ET turn the fan on and see if the test light comes on. Best to use a pin puller and remove the wire and insert a test wire. You don't want to damage your wire. Also you have a fuse put in by Pete. You need to contact them to see if they will tell you location. Could be in fuse panel (sometimes not marked as fan), behind speedo. The fan light on all the time tells me you got a wiring problem. Some use a relay to turn fan on. You need to know if you have a N.O. system or a N.C. system. Air to engage or disengage. The more you know how your system is wired the easier it is to fix. Engine prefix would help and is always helpful when asking a Cat mech. a question. If push comes to shoved you could rewire the fan circuit system. Make sure you put a fuse in the system. You want to protect that ECM.
moldcos21 it’s the temp sensor most likely, because if it was the fan clutch it wouldn’t work manually
awesome i always go with the fuel regulator first.. if i can i put the vise grip on the hose to tank only if its flexible.. and if it starts its the regulator.. old trick
Wait can you explain that better?
More information
Love your videos. Well done and informative.
Have a question, on a 2006 Cat C13 in a Kenworth is there a fuel rail side pressure sensor that would indicate a low pressure condition? Having a situation where it seems the engine is a little starved for fuel when the fuel is hot and the tank is less than half full.
How can a twin gear pump start to put out less pressure..?
Are the gears worn out ?
Basically the gaps between everything get larger lowering the pressure.
whats the part number for the pump and the pressure spring guage
Where is your mechanic shop located?
Nice work
Whats the part number for that gauge and the coupler for the test port??
A hydraulic shop can get you straight you can also use their psi gauge
Where is this shop located?
Hey Josh ! Is there any way I can donate to you in some form of way at all.? As much as you have done for me and you don’t even know it.. I’d Really like to show my gratitude and appreciation.... thanks man !!! 🙏🏻
Hi TJ, you can buy stuff through Amazon that use my affiliate links on many of my videos. I also have a PayPal that I use AdeptApe@yahoo.com if you would like. I greatly appreciate it sir, but you don't have to.
Do you have contact info I have questions, first time cat owner here.
Fuel transfer pump can it repair it is for a c13
I have a c13 motor and trying to figure out what is going on with it was rebuilt by peterbilt 100,000 miles ago year and half and I am getting light water coming from heat side of head along with light oil what can i do to stop this ?
How oil can get in the fuel?
Injector O Rings
my fuel transfer pump exploded, blew metal and oil everywhere days before it happened had low boost, low power but truck kept running, even after it blew apart. anyone ever seen this issue before?
Has anyone ever heard of a diagnostic tool "DIESEL LAPTOPS TEXA KIT" can anyone tell me anything good about this diagnostic scanner tool?
Hey I'm an owner operator based in North CA. It's been a pretty slow winter till now which is always when the rig throws out it's most costly repairs..... Problem, inner timing cover engine oil leak id rank between moderate and severe. Oil is dripping from the area just forward of my power steering pump on the inner timing cover side seems to be a weep hole there. My wallet is quivering already any info would be greatly appreciated.
C13 acert KCB 2007
I don't understand why these fans aren't stationary until operating temperature (say 183-190 degrees
Are they a 700 hp cat maybe 3506
No, a C-18 is capable of over 1000 HP with the correct arrangement.
There is no 3506, the 3500 series engine starts at 3508 then goes 3512, 3516,3520,&3524.
There IS a 3501 engine, but it's used primarily for verification/testing of components and not available for purchase to my knowledge.
Bro please ineed a vid of 3412 blocks pls
I havea 3406e after a few days it doesn't fire right up. A few pumps on primer and its fine.
Things that have been changed
All fuel lines motor and to tank
Transfer pump
Bouth fuel filter housing s
And the fuel manifold as well as the fuel preasure regulator.
I do oil analysis reg and shows no sign of fuel in oil . Does it mean i have a leaky injector if so how do i know which one
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Can someone please help me I have a C15 on my Freightliner Columbia and I bought the truck about a year-and-a-half ago been running 300 miles a day local run had no problems with it at all just recently I just noticed that there's white smoke coming out of my muffler should I be worried
You lied the bigger side is a 1in crows foot not 7/8.
