I pulled the front housing out of the transmission on an H I mentioned a couple of days ago.

The good news is, disconnecting the clutch shaft and pulling the front housing all came apart easily and was easier to do than I anticipated.

The bad news is, per the photo, all that is left of the pilot bearing is the inner race and part of the cage. Using a slim magnet inserted into various fill and drain holes, I fished out seven rollers and the one side of the cage. The ?lump? on the bottom right is what?s left of the bolt that holds the pilot bearing onto the main shaft.

I?m assuming pieces of the outer race, the rest of the cage, and the rest of the rollers from the pilot bearing are still somewhere in the bottom of the trans housing. The other two bearings on the input shaft are a bit rough, but intact. The gears look OK.

If I can flush the rest of the pieces out of the main housing by using either diesel fuel in a hand sprayer or shooting a power washer into the various drain and fill holes, and from the top where the belt pulley was removed, I?ll just replace the three bearings and put it back together. If it comes to it, I?ll pull the top cover to flush it out. I?d hate to have pieces of debris circulate in the gear oil and cause mayhem after the fact.

So far, this project has been easier than I thought it would be. For some history on the tractor, it had a growl in the trans but I was running my log splitter with it. Then last fall I was driving it and something made a ?cracking? noise in the trans, and it locked up and killed the engine. It would roll with the clutch blocked so I pulled it over to my shop with a tow bar. Just found time to start working on it a few days ago.

Diesel in a sprayer is good. Catch it in a 5 gallon bucket under the drain, filter through a rag and re-use.

Also you can take a heavier rag material, denim or old towels, and tie a piece of wire good on one corner and then thread the wire under the countershaft and pull the rag through it will rake a lot of the debris up to where you can fish it out with a magnet on a stick. Tiny magnet on a stick can be used to fish around underneath and through the drain hole.

Probably all the big pieces stayed in the transmission low spots. You might consider pulling the PTO where you can get a visual inside the rear case.

When I have one apart and clean it I buy a package of magnets at the hardware store and put them in strategic locations to act as "filters".
 
Pulling the PTO is a good idea. I hadn't thought of that. That will give a good view through the arse end.
 
On the inside of the trans there are shelves/channels on the sides to direct oil to bearings. Don't forget to run your magnet there too when cleaning. That's where I found pieces of that little bearing when I did mine.

The rollers have their normal type retainer a flat roller bearing uses and the outer diameter of bearing rollers is same as inside diameter of gear. The bearing used in a M has a same style retainer and the outer race is totally separate from bearing. Goes in gear and held in with a snap ring. None of the larger or later tractor ever use a outer race on the pilot bearing as they fit into the matching gear.
 
What does it take to replace the bearing? Also, what's a good source? An IH dealer or aftermarket?

I mail ordered mine from Messicks, had it in stock.
Check your tractor serial number. There are 2 different ones depending on serial number.
and as said, don't lose that washer, it is needed.
