Bolens 800 Transmisson Repair

4823 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 i remember -that is a splined shaft? at least i though so on my 1050`s if it was mine- i would try to put a roll pin thru it- if that shaft is super hard- try it with a small end mill
i think if it was mine- i would disassemble the trans and get that shaft out- have someone run across it with a 3/8 end mill and fit up a step key take the driveshaft with you so you make sure it fits good- you could weld it up and recut a 1/4" keyway but the machine shop with need to check run out for straightness
on second thought- if that relatively soft key mushed the shaft over like that it must not be that hard- it would save you expense if you still got that shaft out- and installed a couple roll pins- that would keep it nice and snug and you could easily disassemble it again if need be
