Rp241441 is reliance number.

bearings at stamped 

mb1409p mb1410p mb1411p mb1412p

im sure someone has them on a shelf somewhere.they made them up to 1990s so surely people haven’t replaced that many main bearings?

If you have taken the pistons out, you are already aware that they have to come out the BOTTOM of the block.

(rod ends are too big to go up the hole)

There is a special ring compressor, IH made for putting them back in. Rarer than hen's teeth, I'm sure.

Sneaky re-assembly tip is to put just the bottom oil ring on the piston, compress it with a large hose clamp, install it up in the sleeve, push it up as far as it will go, then install the upper rings on the piston, and install with a normal ring compressor.

(It took more than a 20 minute stare to get that done 😉)

Good luck

Mike

I managed to come across z machine out of Iowa that had bearings.Extremely expensive!

now the head shop says head is full of cracks.so back to parts searching for a head. This thing is a nightmare to find parts for. Now my list consists of head ,head gasket ,and rear oil seal quill that takes the rubber seal because new crank has no groove.

so much for a quick rebuild.

I hope your U/C is in good shape. There are likely no parts available whatsoever.

Undercarriage parts are pretty easy they are all just cast no precision really.luckily mine came with new tracks rollers and sprockets 👍

when you get a machine this old I’m sure everyone that has one has a cracked head or bad undercarriage or uses a quart of oil an hour.I’m just looking to fix mine cheaper than someone else’s wore out machine.not saying his isn’t in perfect shape.

A lot of the old IH gas starts here in the old days, but good head for any is near impossible.  A never repaired one is like looking for a unicorn.

So I finally got everything put back together on the engine. Run’s good with around 60psi oil pressure.Does that seem high to anyone? Also noticed it seems to shake the firewall a bit. Has anyone had problems with the d461 shaking or is that normal?Not as bad as a Johnny popper but not as smooth as a dt466.

Glad you got it back together. Can't answer your questions. The crawler guys hang out more on the construction page. Maybe somebody already suggested that. I didn't go back and reread your whole topic. Good to see somebody saving these old machines.

If I forget to put the bolts that go through firewall behind air cleaner in the firewall rattles a lot. Mine doesn’t run smooth though, she likes to only hit on 3 of the 4 cylinders. As far as oil pressure mine has the original no number gauge. It’s being borrowed by my H

So first start of the day gas is 80psi oil pressure and stays there on diesel until 180f water temp then is 50-60 .

low idle is around 30 when hot.

it seems I have #2 cylinder not hitting solid. I crack injectors and all stumble except #2 does not. Good flow when cracked and I can blow through injector when removed.Little stumped.
