Detroit 4-53TIB Pulling The Liners And Pistons

Pulling the liners and pistons to correct the low compression issue I'm having. Found a few issues with the coatings on the bearings as well as the pistons.

You never see anybody hone liners any more, nobody wants to save useable parts when they can just buy new and I’m loving your videos showing how to do things right and not throw money away.

Glad to see your positive :) and the diagnostic is always interesting

[akfarmboy]

I’ll make that tool also.
I like the light hone, new rings, clean pistons plan.
I’m not so concerned about the bearings. Maybe I’d think different if I saw them in my hand.
Good video and information thank you.
I guess I’d get good look to see if the ceramic is imbedded skirts of pistons. Might need micro scope.

Catching this early may be a blessing, Could be a lot worse. Good Luck and Thanks

Already subscribed but just now seeing this….grrr YouTube. Even though it is a pain I’m so glad you caught this before truly bad things happened. Also, that liner tool you made seems pretty awesome. I wonder if others like the Bus Grease Monkey could use something like that.

Cavitation....you probably meant detonation!...or I do not understand! Thanks for sharing.

You ever use aircraft paint,
It's called calguard spray it on bake in oven to cure😀😀😀😀you must try.

Those witness marks may be where they held the part while coating them. I guess they tried everything before their final design. Check that top ring land for wear from the coating dusting it. Thanks!!!

I think the crap...sorry, coating ;) flaking off the piston got into the bearings a bit. Not sure about on a Detroit but I think a bypass filter sees less than 3% of engine volume at best, I'd imagine a fair amount got through the system as it were.

As always, you've got a plan in action that will take care of that and get Jimmy screaming up the BC mountains again

Great tool ! Unusual bearing shell, haven't seen that colour before only on over heated motors , almost as if it's firing to advance, my guess if it's possible, thanks for the update !

As for the bearings coated bearings they have to remove Material off of the bearing to put the coating the coating is a Molly graphite coating moly graphite coated bearings it's designed for an engine that is going to be tore apart a lot it is designed for more like drag racing application it serves two purposes protect the crank and show a clear where where pattern that the engine builders can keep an eye on the make sure the bearing is wearing properly for a high RPM high demand motor a bi bearing or a tri metal bearing is the best bearings for the application I prefer trimetal bearings as for the coating coming off and getting into the Rings I've never seen a crosshead piston what coating on the head of the piston only on the skirt and why it's coming off with only 16000 miles I am not sure I don't know the manufacturer of the liner kits that you used either great job catching it early so it didn't create any more damage than it already did

[lukestrasser]

I’m disappointed by the coating, but I wouldn’t discount the ingestion of crankcase gasses as a cause for some of the deposits as well. That oil vapor is sure to leave behind ash deposits that Detroit’s hate.

[joemaser]

The easy way to get the pistons out of the liners is stand the liner on the floor put a foot on each side of the and hold the flange down and pull out the piston

[ronfrance]

That’s an awesome liner removal tool! Not sure if anyone makes those to sell but if not you should think about

[gaetanbolduc]

Good that you decided to take it apart! Could have damaged all liners and pistons! Would the carbon deposits coming from lack of compression creating improper combustion....and light duty cycle?

[prevost]

When it rains it pours around my place. Hopefully this will be the final time that the cab comes off for a while.

[rdukes]

Great work, thanks for sharing.
looking forward to seeing what your main shells are now like.
what about the gudgeons?

[Peter-V_]

I wonder how much of that swill ended up on the valves and

[pulsenpal]

greetings--you indicated crankshaft was "new"--is it factory oem or aftermarket?

[rickbrockhouse]

How are you going to remove the old coating off the pistons?
