Tearing Down the Marketplace Big Cam Cummins (Is It Salvagable?) 

Does the radiator have cooling power to cool this engine

Hey my man just wondering did you look if you can open the washer door from the inside before you went in.

Well you got it all torn down you might as well paint the block and make it look good

if you actually manage to put this engine back together - hats off to you, man!

Your store only has small hoodies, can't order if you don't have any.

Thanks! You too!

Yup, that’s my plan. I’ve got a list of stuff to sell

That's what I wound up doing. I had a string of half a dozen sales where idiots bid things up over retail cost and then never paid. I never put anything up for auction anymore, I just put a price on it and wait for it to sell. I usually underprice things because honestly I just want things to go away.

I click 👍on *all* videos I watch as that is the only way I am able to show my appreciation for the entertaining and education content provided to my rapidly declining old brain. If you look at the number of Views and then the number of 👍is is a disappointing 5% to 10% of the view numbers. I don't understand why a single mouse click is so hard for those who watch the videos to provide the Content Creator a small token of their appreciation for their work. 🤷‍♂ Um @Mark_I_Am, do you like Green Eggs and Ham? 🤦‍♂ (Sorry but my primitive brain couldn't resist.) I enjoyed Mr Geisel's books 63 years ago and I got to relive that enjoyment again when I read those same books to my daughter before bed time. My only regret was that she absolutely loved _Fox in Socks_ which was a bas-turd of a tongue twister to read almost every night. Apologies for going off topic and babbling but it was some happy memories for me. I hope sir that you have a great day, week, month, year and life. 👍

That’s what I was thinking too.

You are correct. But it could also be exactly what Matt said. Only way to tell is assemble them and check spring pressure rates.

I was thinking much the same line but, spring height has something to do with it also. Regardless, these big cam engines are pretty close to bullet proof as long as you’ve got some oil pressure and compression, and in this case not being turned up too much.

Great lesson for the shop and for life in general: just because somebody "less experienced" comes along and points out a mistake you made, doesn't mean you're being personally indicted as a trades or craftsperson--it just means you're human and you messed up. "Hey, good one new guy. Thanks!" would've led to a turbo *not* blowing up in this case. But hey, then we'd have been deprived a valuable workshop parable, so where's the fun in that? I bet that "master" mechanic paid a bit more attention to procedure after that... I'd hope so, anyway.

How is a valve having slightly less tension than specified gonna blow a turbo? Like, was it bad enough that it had basically no force and got hammered by the piston on each rev?

He’s gonna wish He had installed that crane Before he filled that shop with projects …..

My dad’s a great man but he didn’t teach me hardly any of this. I’m mostly self taught.

@user-fz6vs4de9m 😮Was that engine out of a tugboat, destroyer, or a submarine?

Measure gaskets/shims for lifters covers . You need to reassemble with the same thickness

probably best to start from the beginning again anyway.

OOPS!!!

Good machine shop that goes the extra mile to make it right!

Yes sir I have a tendency to gravitate towards these You Tube videos that give a good narrative of the project. Yes there are some that have some humor but also give a good presentation and yes there are some that are downright silly. This channel I like to watch as Matt gives a good presentation, and he knows how to talk to the camera which is a good point.

LMAO

I'm torn....I'd say there isnt ANY good part about being up at 0500 on a SATURDAY. But you didnt say good you said best. I just really dont know what to do with that. 🤔

@Dildo_Baggins. I mean if I have to be up,no better way of waking up and enjoying the start of the day. I agree,though,waking up at 5 isn't top choice. Haha

I thought I was the only one with a cup of coffee at 5am waiting on Matt to drop a new video. You know I enjoy his channel more than anyone else cuz he’s just a humble guy that knows what he’s talkin bout!! Here’s ya ya Matt!!

You got that right

Do you burn those pig mats after they’ve been used?

Many people don't know this is the only way to set the proper injector timing on an 855 Cummings. I've seen people put the wrong thickness gaskets on not knowing and can't figure out why the engine runs like crap.

hope he has a timming tool or mic the gaskets.

You will need to find the correct setting for the cam follower plates based on the engine number, the tool and proceedure will challenge you, its not easy without the manual to explain it, get a cummins one, it can be a right pain, trial and error! Check liner counterbores as the liners can and do move and wear the block, machine shop can repair back to standard, i worked for cummins for 12 years, these are good engines if done right

@@prowler2358 data plate won't do him much good here, since the engine is supposedly set up to 600+ hp. In stock configuration you are absolutely correct, but as you modify these engines you have to consider things like compression ratio and injector timing to keep from melting them down.

Reorder the gaskets/shim as per part number of each gasket/shim and you can install them with out having to reset the base timing Don’t measure the gasket/shim as they have been compressed I have rebuilt many different versions of the 855

Need a timing tool and shim gaskets 3 sizes of them

Yes sir the crankshaft in that engine can be as heavy as a complete automotive engine, and of course everything is larger. If your tool infrastructure is geared towards automotive engines then you can be in for a shock when you fool with these big diesels.

Little does he know…

Agree.

Repairs to the old beaters, I enjoyed the battle, the savings and the education. Now I pay n pay lol

I just let the apprentice swing the hammer. "Bet you can't get this pin out". Works every time😂😂

Matt needs to hire a Pakistani to swing that hammer…

🤣🤣 I'm a retired diesel mech and I also used to change Sunstrand pumps and motors alone in confined spaces usually underground . I can't believe how strong I was as a young man because I certainly cannot do any heavy work any more

I was going to ask Matt about that glad you gave the explanation here.

You and me both!

That sounds sketchy. I get it, but the impact shock from hammer strikes helps to break thing loose better than brute force. Not to mention if something binds up you won’t really know it.

Ex​@@erikcourtney1834

@@erikcourtney1834 Industry standard is pretty much 'beat them out w/a hammer', otherwise my actual comment as a machinist would be "never use a hammer unless you have no other option". I've never witnessed a sleeve being mechanically or hydraulically pressed/pulled be ruined. I have however had to condemn more than one block because someone w/the best of intentions had a bad day while swinging a large hammer. IMHO, all involve real pros/cons, I've never 'mucked' one up using a forklift or supported crane boom but I'm still young.

​@@adf360Thank you. Sketchy, SMDH. It's a popular internet insult word these days for people that don't have experience.

Using hand tools is the best way to know how much force is necessary. Forklifts don't give any feedback to you! 😂

It does!

For sure!

I’m hoping he has a dial to check and a hold down plate 😊

I love your “do-dad parts” and your tear down chaos.

yup, he has a heavy-duty table

Yep was thinking the same thing. I picked up a heavy duty industrial scissor lift table at auction cheap since it was old and 3 phase operation. Sometimes that stuff can be had way cheaper than the smaller single phase ones since Joe Homeowner will pass on it. Run it with a Chinesium drive with single phase 240V input and converts to 3 phase output. Works great. If a unit was 480V will also have to move some wiring on the internal controls transformer(s) and pump wiring to low voltage setting and maybe a fuse change but easy enough to do.

As a silicone user, it's pretty amazing how a few mistakes in application can show up in pickup screens. A former employer taught me how to apply silicone "correctly". Dab it on your finger and Thompson and apply to the gasket by pulling it between the 2 fingers. Generally less is more.

They're a plastic tube that goes in through the block side on these. When he was beating out the liners, you could see the white plastic. Very much with you on it being wise to change them, and very much agree that a poor sprayer can create scoring. Especially in a turned-up engine.

Thanks so much!

Thanks for watching!

Check out kt3406e he does cat engines

Yeah, you've been around awhile. The H was a 2-Valve head engine with5-1/8" bore and this one is an NH, or 4-valve head and 5-1/2" bore. The single and double disc pumps were gone by the time I started.

I appreciate that! I like to re invest in the channel and things that help me work faster and make better content

Now he can clean himself up at work!

Just because puddins fab shop cleaned that way, does not mean everyone else should.

Matt should be careful about doing that. It might give Miss Eva ideas about how to stop him coming home covered in who knows what....

😂

Lol

100%👍

Already in the works 😎

@@DieselCreek Glad to know! Just finished the episode and am already ready for the next! enjoying the series alot lol
