Bolens 800 Transmisson Repair

4826 Views 14 Replies 7 Participants Last post by  Frustrated Farmer
I have a Bolens Husky 800 tractor with a 3 speed transmission. The input shaft to the transmission needs to be replaceed. The keyway in the shaft has become worn down probably due to the jarring from plowing snow. I have tried a new key but it eventually slips. The tractor moves, stops, then moves again.
My question is how hard is it to replace the input shaft? I consider myself fairly good in mechanical aptitude. Do I need special tools? Would it be better to find a repair shop? Just wondering what I might be getting into. I have the Bolens manual but it only talks about putting the transmission together not disassembly.
Any advice would be appreciated.
Thank you

if you are using it for plowing, I would recomend getting a rear/trans out of a 1050 or simler with the hi/low gears. I have seen 1050's for a couple hundred bucks that ran and worked, so you could get something like that to plow and use the 800 for cutting grass or other work that is not that hard on the gears. I have a 750 that I tried using for tilling...I was constantly clutching it and stripped the gears in the rear. I bought a 1050 with the hi/low trans, what a differance. if you wanted to fix it, I would grind the key way a bit bigger and put a bigger key in it, of course you would have to grind the other part to fit, if you drill out a hole in the part the key that holds the key in you could put a set screw in there to hold the key in tight. you could also drill the shaft if it isn't to hard of steel and put a bolt through it. ggod luck dt
