Thats very common for rod end bolts , so mains and head bolts .

Re: Case 680E
The piston didn't come out easy. Pounded the skirt from below with mallet and a piece of rebar. Fought me every 1/4" of the way. Worked up a sweat!
Eventually it came out. Now we know why there was no compression in this one.
The sleeve though isn't budging. And I'm done for today, beat.

Re: Case 680E
A little JB weld on the piston and a quick hone and your all set .

Watch this . I have some of the material need to make it . You will need to get the threaded rod . I can machine the pieces you need for the bottom if you get me sizes .
There is a reason they make these pullers .

Great progress Eugen. Two pistons I took out of my tea20 Ferguson tractor, four years ago, were like that. Not as bad, but similar.

@Eugen Holy crap those last couple of pictures are ugly! I guess we all knew it would be. On the plus side it’s lucky that engine didn’t have a catastrophic failure.
I would bet you can knock those sleeves out eventually with a lot of pounding and cussing I think Mr. Dave has the idea on making a puller, much easier and hopefully less busted knuckles!
You made some great progress! I can almost hear that rebuilt engine humming along…..

Re: Case 680E
Thsnks for coming along on this ride guys. Your suggestions and ideas are appreciated, it helps me.
Yes, I got to make that puller. I'll see what I can come up with and reach out to @DavidBarkey if I get stuck, thanks Dave!
Yesterday was family day, a fairly new provincial holiday in Ontario, so I didn't have to go to work, that's how I was able to put some hours in wrenching. But after 5 o'clock I was happy to be with the kids. Then I made some sausages on the grill and had a well deserved dinner, then more playing with the boys. After they were asleep and the night chores were over I was burning with curiosity if the crankshaft connecting rod journal was standard size or oversize, and what condition the piston pin is in.
Was glad to see that the connecting rod inner diameter was 2.75" and therefore STD. The piston pin is in great shape and measured almost 1.625 as per spec.

Re: Case 680E
The sleeve puller is the priority atm. Found a 7/8 threaded rod and cut a 5x5 piece of 1/4 inch plate. Will try to turn the plate on the lathe to fit the bottom of the sleeve. Will have to look around for a top bracket of some sort.

Re: Case 680E
Good start . Based on what I saw and have heard from heavy equipment mechanics it need some sort of back up material . Once you have it down to just under outside diameter of bottom diameter of sleeve and you hole in centre. Tack some pieces on the face of it you can turn down to the ID of the sleeve to keep it centred . As for the top plate and uprights . I have some heavy bar that you can have . It was given to me , so come get it and make some use of it . I will send you pic.sEugen wrote: ↑Tue Feb 21, 2023 12:25 pm The sleeve puller is the priority atm.

Re: Case 680E
Thanks Dave, I just found a bracket made a 3/8 plate in my empire of junk, already welded and about the right size. Needed a one inch hole. I'll see if I can finish the bottom plate later this evening. Good point about making it beefier, I was thinking myself that 1/4" might be a little flimsy.
