mowerman Posted November 13, 2022 Share Posted November 13, 2022 I don’t think your sleeves are going to pop out but who knows I freed up a Chrysler slant six years ago just with mystery oil at typing the Pistons real light with a chunk of wood and I hammer again patience don’t get in a hurry but If the rings are rusted to the cylinder walls you’re better off to punch them out and at least clean everything and reassemble .. Good luck Bob 1 Quote Link to comment Share on other sites More sharing options...
mowerman Posted November 13, 2022 Share Posted November 13, 2022 At that point you might as well just do a full in frame.. bob Quote Link to comment Share on other sites More sharing options...
The Rubber Duck 006 Posted November 13, 2022 Share Posted November 13, 2022 You Guys talking about putting gaskets on brought back memories of my Grandpa. He worked on trucks back before he owned them and even after he owned them of course lol. He always used thin sewing thread to hold any type of gaskets on while setting them.

I didn’t realize they had all this for these still. I hope I don’t have to get into sleeving this motor, but if I have to, good to know they still make parts. Do you know if there’s room to drop the oil pan with the motor still in? I’ll get under there tomorrow to look. There’s a good machine shop close that could do the crank if need be. Man, I really hope not. I’m really hoping for a nice clean up and breaking it free without busting anything. Would be nice if all I needed was a gasket kit!!

mowerman Posted November 14, 2022 Share Posted November 14, 2022 I have only done one and that was in 1986 or as I remember everything was like 1200 but that included all six holes But that included sleeves pistons wrist pins bearings gaskets frankly up I was going through the urge of that was what I would do especially on a clean up keeper … bob Quote Link to comment Share on other sites More sharing options...

Man, I wish I would’ve paid more attention to some of the stuff my grandparents were doing when I was a kid. He would run the thread through the Stud holes or bolt holes and basically loosely tie the gasket to whatever he was putting on ( Water pump,intake manifold, exhaust manifold, heads etc.) The thread doesn't hurt the gaskets and once you set whatever it may be in place it easily cuts the thread and he could easily pull the thread out and the gasket was set. 1 Quote Link to comment Share on other sites More sharing options...
BOBWhite Posted November 14, 2022 Share Posted November 14, 2022 Wow that's cheap! No good reason to have a rough running engine with that price! Will an E6 kit work on an END675 series engine? Ive never seen a kit available for one of them. Also did they go to wet sleeve with the E7? Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted November 14, 2022 Share Posted November 14, 2022 12 hours ago, BOBWhite said: Are these dry sleeve or wet sleeve motors? And if they do pop out why could't you just reseal it and pop them back in? You can check the condition of the cylinders and check for cavitation if they're out. Also do Mack's have problems with dropping or sinking liners like Cats do? I'd imagine sleeve shims would not be easy to find for one of these. If someone is putting a lot of force on a crank to move a seized engine then pushing as sleeve out is well with in a possibility Then as Joey suggested these are a press fit or freeze and get back This is all gunna be a challenge with a pistion still stuck in a sleeve Anyway thats how I would deal with it Paul Quote Link to comment Share on other sites More sharing options...
mowerman Posted November 14, 2022 Share Posted November 14, 2022 I know you’re probably not ready to spend that kind of dough and it’s probably more than what you paid for the truck … but everything on these trucks are a fortune ….

Joey Mack Posted November 14, 2022 Share Posted November 14, 2022 If you end up having to re-build this engine, before you buy the kit,. Specify if you have a turbo or not, and head bolt count for the gasket kit. I'm sure there is a few other things to ask about. They may ask for the current piston part number on the piston.. no biggie, just be prepared.. jojo Quote Link to comment Share on other sites More sharing options...

Freightrain Posted November 14, 2022 Share Posted November 14, 2022 Before I would start buying engine kits, I would look around for a 237. Find a running engine for the cost of a rebuild and have more power to boot. Granted, even a 237 is getting hard to find in decent shape. I was REAL lucky when I walked into mine for $300! Even if I did have to do a bit of work on it. 2 Quote Larry 1959 B61 Liv'n Large...................... Charter member of the "MACK PACK" Link to comment Share on other sites More sharing options...

Even if I did have to do a bit of work on it. I put this up in Craig's other thread about if a 350 Cummins would fit under the hood of a B42. I have this R model with a super healthy 237, 6 speed lo hole trans and Mack rears if someone needs a powertrain. Truck is crusty but the powertrain components are great. And it has jakes on it. $2500 in Pittsburgh, PA. 1 Quote Link to comment Share on other sites More sharing options...

In my mind, open it up and see what's there pulling liners on this old stuff can be a nightmare I have had it where the whole weight of the truck was on a jack and a plate before the liner would move back when we had nothing! We had a porta power at work to do this job ! Just saying ! Let's see what you got bro! as Joe mentioned welding the liner can shrink it however myself I would opt for a quick hone and new rings at most! if the liners are not scored up! Just stuff to think on! 2 Quote Link to comment Share on other sites More sharing options...
Craig N Posted November 14, 2022 Author Share Posted November 14, 2022 I’m really hoping that the liners are in nice enough shape along with the rings. This is just a toy and I don’t really want to rebuild the motor. I’m going to see what I have when I get the heads off and go from there I guess. I would probably go for 67R models Mack listed above before I rebuilt the 673 I have. A running 237 would sure be nice. That seems like a good deal as long as I can get it here cheap enough. A running truck to pull the motor out of is is a big plus for sure too. I’d probably just swap the whole drive train at that point. It would be easier to pull the cab and nose off and do it all at once I imagine. Here’s to hoping that the engine I have is clean enough to re-gasket and put back together. 1 Quote Link to comment Share on other sites More sharing options...
Freightrain Posted November 14, 2022 Share Posted November 14, 2022 The one thing you would have to do IF you swapped the whole drivetrain is hang the R clutch pedal in your cab. It's a cable pull clutch so it would not work with your existing pedal arrangement(push style). If you have the baby quad in your truck I would recommend swapping the drivetrain. I do fine with my Triplex but it is much stronger(though still limiting). 1 Quote Larry 1959 B61 Liv'n Large......................
