Greetings all,

does anyone know if 2 different size bearings were used on the first motion shaft where the clutch housing fits? I seem to have an inner race that is too big for the outer shell in the housing! The housing won't push onto the engine/box! Any comments appreciated.

Yes, the later outrigger bearings are different bore in the outer ring. You MUST replace the ring with the one in the box, to fit these bearings.

Thanks Doc. Is there an easy way to remove the ring from the housing, or is heat the only way? Thanx

There are various ways. Proper puller is nice but no... I don't have one.
I weld a big flat washer onto a bolt, sit the washer & bolt inside the bearing and lightly tack weld in 6 places with the MIG.
Then I put a piece of exhaust tube on the housing over the bearing, with a THICK washer, put nut on bolt and wind it out. Easy peasy.

Make sure you remove the little snap ring/circlip, first!

Hot tip - while trying to think of a quick and easy way to remove the shell, i spotted my heat gun paint stripper. Gave the housing a quick blast with that, turned it over, hit it with a BFH and bingo - bearing shell dropped out onto floor. Took all of 2 minutes, including getting new one in. Better than using oxy-acetylene!!!

Wow thats a good one and Quick also

Just be careful using heat on cast items like the gearbox housing. Too much, and you'll change the metal structure causing stress raisers, and embrittlement.
