From what I can tell, I would need to remove the hubs in order to check the bull pinions?

 its a big job. you need to remove the diff. housing from the axle housing. remove brakes. the brg. cage is then removed as one unit. . but check on bull pinion shaft for movement once you get brakes off. if no up and down movement they might still be ok. i know this is common on these tractors. do you have a  shop manual ?

Finally decided to start a thread on this board. As some of you know, I'm restoring a 1949 McCormick WD-9. I bought it as a tractor which shouldn't have needed all too much work. Tractor r

I have service manuals for the tractor. The brakes need to come off anyways so I will check for shaft movement when I have them off. If I notice excessive movement, I will then replace the bearings. But I hope I won't have to, because it sounds like a huge job.

Well your almost there now may as well check, note that Sam said his felt good and when he pulled it out witnessed accelerated inner race wear

Time for a small update.

Haven't been able to do too much because I had school exams over the last month. Got some small things done like putting the transmission cover back on and reconnect the steering. I also took the brakes off to check the bull pinion shaft. Movement is absolutely minimal, barely noticeable. So I will not change it for the time being, but I might do in the future as I'm still not completely confident because of the pictures I saw.

I have started on the parts block this week. Cleaned it with the high pressure washer first and took the oil pan off. Block wasn't supposed to be stuck, but it was. Got it loose with a large chunck of wood and a big sledgehammer. One sleeve is completely filled with rust and that piston is shot too it seems. I will try to get all pistons out this week and post some photos too.

Worked on the parts block tonight and got a lot done. All the pistons are out and the crankshaft too. 2 pistons look great and 3 sleeves too. The other pistons and sleeve are not usable, but I was lucky because the previous owner of the tractor had 2 good pistons and 1 good sleeve laying around. Also pulled the first sleeve, to see how hard it would be. It turned out to be pretty easy actually.

I am planning on swapping the crank, because the one in the parts block is much better. The main bearings seem almost new! Rod bearings are much better too. If the crank is the same, this shouldn't be an issue right?

This is the sleeve I can't use anymore. There are chuncks missing from it. The piston is garbage too.

These are all the parts I got out tonight

on these engines you have to do what you have to do... parts are scarce and expensive.  long as things look god and clearances ok it will run. those 2 pistons look like almost new.

Worked on the tractor again last week. Cleaned all parts up; bearings, sleeves and pistons.

I will bring the sleeves and pistons to the so called "Zuigerverenfabriek". Translated the "Piston ring Factory". They make a lot of piston rings. They will custom make my rings to fit the pistons and sleeves.

Further, does anyone know a place where they sell rebuild kits for delco starters? I have number 1108925 but I'm not able to find a rebuild kit for this starter

Thanks!
