Greetings friends.......Ted's posts on looking for a powershift inspired me to work on a few I had in stock. It has been 2 years since I tore any down and rebuilt the trannies...so it was a trip down memory lane...and a few trips to the service manual! I just tore down a 8-24 that had shifting issues, and the several I did a few years ago had the same issues. I love the powershift platform...so I'm not knocking it....and the only ones I see have shifting issues..cause I only buy broken blowers. what I see is the weakness of these fine machines, is that after a number of years, ....20 ? ....the grease in the trannies get contaminated with water or moisture....maybe condensation.......but the end result is rusty grease and gears. they bind up and the machine is junked, because no shop I know of will fix them. It is a few hours work, but a half hour to pull the tranny ...and several hours cleaning, wire brushing on the grinding wheel each gear, shaft, thrust washer...etc. and reassembling all parts with new grease usually makes it new again. Please don't give up on these old warriors...they can be saved!
