Working on a engine with them tools sure will bust the hell out of your knuckles. I lost a lot of blood that way not to mention a few choice words that came to mind. Makes me want to jump in and help. Can’t wait to see your next video. Thank you
The Cummins 855 big cam is an awesome old school reliable engine my Boss had one in his racing truck it was a Leyland roadtrain he raced in the B.T.R.A British truck racing association. Here in the uk and in Europe with it . He managed to get 850 hp from the engine with a lot bigger turbo i think the turbo came off a k19 he also advanced the timing and fitted steel topped pistons to it so he could put more fuel in without burning the tops through on the pistons he literally did everything you could to the engine to get as much power as he could out of it opened the fuel pump right up . It was a very competitive truck in its day he now races a MAN 12 liter. But it doesn't sound a patch on the old cummins the cummins had a noise of its own there a great engine more reliable than any of the new crap in modern trucks of today. Keep up the hard work my man love the videos respect from the UK brother. 🇬🇧.
One thing I learned the hard way when working on engines, steam clean the life out of it before you start. Steam clean it good, then spray the rust eater on every bolt your gonna touch. Let it sit over night then steam clean it again and then take it apart. Your life will be some much easier while you work on it. I also learned a old trick from my old mech who died last month (rip Benny), if the engine starts or even cranks, drop the oil and load it with diesel. Let it run for a few minutes and work the diesel in the engine. Then drain it and take it all apart. You will be able to see much better what’s going on in the engine while your pulling it apart. If it don’t crank just load the oil fill with diesel till it over flows. Let it sit a day and then when u go to pull the pan and get the bottom end, you will have a much easier time pulling everything apart and better chance you will not snap a bolt on these old trucks that been sitting for years. And once your done with the rebuild, you need to “pig the block” it’s a method used to clean the oil gallies out (you need to speak to a machine shop or master tech and they will explain it to you better then me) and all the oil channels. It will make sure you didn’t leave any dirt in the engine that could ruin your new bearings or crank and cam. Good luck sir.
I work on a fishing boat with a 855 big cam cummins I sure wish I had all ur knowledge. Your a big deal to be that guy on a fishing boat. And do deck work! Guess I gotta keep watching videos like this. Thanks for making them
Just bought my dream truck, cool to me anyways but it’s an 88 IH Cab Over and she is rocking a big cam in her, bout to do an in frame some time next year, really nice motor to work with, thanks for the video man and I’m subscribed! 😎
Wow for sitting for awhile Jake's rocker boxes and pushrods and heads look good but definitely you decided to pull the head off and inspected it further but thank God it wasn't a real big crack and you can probably get if your Pistons and liner from Peterbilt but yeah like you said it's better to do an in-frame that way you know what you got when you get done and you know it's going to last.. Buddy did you ever come up where is a motor for the 75 Pete but yeah I would Focus on getting the 84 up and running and driving before I would stick money into the 75 just because the 75 needs more work then the 84 does but really happy everything looks good for setting for a long time besides that one piston really happy it wasn't as bad as you was told it was... catch you on the next one brother have you found an in-frame kit yet buddy catch you on the next one
Dude, your going about this the hard way. Remove the Jake, rocker boxes, back of the jam nuts while they are still on the heads, then remove the water manifold. When your taking off the intake manifold leave the three bottom cap screws in the heads with the gaskets in place when you go to install the aftercooler.
Beside the cracked piston the three- four cylinder head gasket looked to be blown. Doesn’t explain why she wouldn’t roll over. Pull the main bearing caps while your there may have a spun a bearing. Those engines are very easy to build however you will need a liner puller and a torque wrench capable of 600 lb/ft to reinstall the heads/bolts.
Nice video brother...I need your honest opinion on this: i was looking to but a truck and I came across two 1989 kenworth T600 one have Cat 3406B engines with head gasket problems the owner said it overheats and the second truck from a different owner 1989 kenworth T600 with 350 Cummins engine , according to him the truck is ready for work , it have 35,000 miles since the inframe job. I have never owned or driven any truck either engines. Since that you own Cummins what would you recommend?
Both engines are good engines, I would say it depends do you want cat or cummins I like both but if the price is the same I would go with the running truck. Does the owner have proof of the inframe? The cat is a great engine but if you cant do the work yourself the shop will charge you alot, the cat is said to have an head gasket problem but it also could be the head itself, If i was to pull the head i would probably inframe it as well. I would say go for the running truck. If you can get that cat truck for a lower price and have it fixed it would be the better engine. Im guessing that cat is a 425.
Keep up the good worK! There are a lot of guy out there that don’t know shit about turning wrenches. Be careful with the wrenches. They tend to slip often making you bang up your fingers and everything connected to them as well as making up new foul language. Lol! I have come up with quite a few doozies in m time. Lol! Hope everything works out for you.
A bro just so you those harbor freight meatal stamps work good it's a kit with letters and numbers in it so you can hammer in the number on each head and jake box or maybe I'm just too anal

nothing but respect for you. watching do that without an impact driver was painful, but I've been there.

Thank you for making this video, and putting it on TH-cam
Awesome to see. I got 79 kw with a big cam. I’m literally doing this myself thank you 🙏 for the vid
I messed my crank up though

Love to see that you are showing most of the steps for us who are not mechanics thanks for that boss
Great video! Got some really helpful shots of breaking the cummins down. You're getting there!👍🚛

Back again my favorite TH-cam channel

Keep up the the good work bro im with your channel until this bad boy runs💪
I hope your old truck works well for you.
Like your videos keep them coming great work I hope to do my 85 359 one day

Good job and good video 👍🏽👍🏽
I have to get back to work so I'll pick up the rest of you after work

I don’t have this truck anymore
An upload on my Birthday, Awesome👍
Happy Birthday
@@MR75PETE Cheers! keep up the awesome videos👍
Great video
How much does a rebuild kit cost for the Big Cam Cummings?
Beside the cracked piston the three- four cylinder head gasket looked to be blown. Doesn’t explain why she wouldn’t roll over. Pull the main bearing caps while your there may have a spun a bearing. Those engines are very easy to build however you will need a liner puller and a torque wrench capable of 600 lb/ft to reinstall the heads/bolts.
It was a couple bad rod bearings ate one up and already have liner puller and big torque wrench
Great job, wish you had some help with those heads!
To put the heads back on the a 5" 1/2 13 bolt and weld a round rod on it and screw it into the center rocker box bolt hole makes it much easier
Explain again?
@@outlawdiesel5221 use a 6" 1/2-13 bolt cut a 6" piece of 1 in. rod to make T handle to make it easier tohandle the heads
Yea that center head should have 4 pipe plug in it some time all the heads do but I know the center head dose for sure

What are some things I need to look out for or upgrade to with this motor
Hey bro I need to talk to you I got a 1988 Freightliner FLC with a big cam 400 I need some ideas and questions answered

I have come up with quite a few doozies in m time. Lol!
Hope everything works out for you.
I'd would try to find a building to rebuild that engine
have you figured out why it was locked up yet?
What's up
Hi
A bro just so you those harbor freight meatal stamps work good it's a kit with letters and numbers in it so you can hammer in the number on each head and jake box or maybe I'm just too anal
They were already marked and i didnt notice till today.
@@MR75PETE nice
You look like you've done this before.
I better heads weigh over 100 pounds
Close to it im sure
If your going to do a newer truck cut off put it on the newer truck the newer truck is a better truck
Awesome video
