Earlier this year I picked up a B112 in pieces. It had been split at the Bevel gear box. The bevel gear box was blown and missing it's guts. It came with the hydraulic lift and a 48" original B series mower deck. Missing from it are a gas tank, starter generator, rear wheels, seat, seat pan and the BGB guts. Last year I had bought the 42" snowblower from the same seller as well as the original AC rear moldboard plow. Just this past monday I picked up another B112 in a trade. I was lucky and stumbled across this. This one is missing the gas tank and starter generator and someone had welded some cross braces to the frame under the area of the shifter. My goal now is to make 1 decent AC B112 with Hydraulic lift from the two machines. It looks like they are both parts tractors but between the two it will be worth it to make one. So far I pulled one of the transmissions apart and found I need the pinion gears. ( if you can't find them grind them ) obviously years of grinding the gears does wear them out to the point where their in need of being replaced. I started to buy the tranny parts ( except gears, hoping to find a good used set ) and look forward to rebuilding it. The guy at the Simplicity dealer said if I do it right the tranny will out live me. That kind of made me think a little ? After the tranny I will do the bevel gear box and then bolt the frame to that. Hopefully I can do it all this winter.

I've seen many 3 speed trannys sold for $50-$75. I'm not sure you can rebuild it for that. In fact I have even seen them listed as free if you pay the shipping or pick up. Think I would look for a complete unit.

Yeah, The parts can be expensive. I want to rebuild a tranny to learn how and it's worth it to me if I can learn this skill. If so I will go through all my tranny's on the tractors I want to keep for some time. It seems that they all leak at the axle seals and gasket and like the dealer told me , if done right it will out last me.

Hello, Check the axle tube in the housings. My B-10 saw ground engagement duty all of it's life. When I got it from my grandmother in-law, it was leaking at the axle seals. Jacked it up and the axle tube was sloppy in the gear case. Enough that the seals would not hold back the oil. There are bronze bushings in the gear case halves that were worn. These are not available. Instead they sell a roller bearing that naturally is not a direct replacement. Had to take it to the machine shop to have the case halves bored out to accept the roller bearings. Much better set-up but wish it would have fit in the standard bores. Also replace all of the key's in the gear case. You will find a lot of wear in these. Good luck. Andy "It seems that they all leak at the axle seals and gasket and like the dealer told me"
