Snapper LT125 - Drive Belt Replacement

Your mower has a Tufftorq K46 hydro transmission. These are known for early failures. Sure hope I'm wrong but I suspect the drive belt is not the problem unless it's totally shot.

I should find out in the next 48 hours. the pulleys and belt shoud be here tomorrow... Crossing my fingers that it's these maintenance items and not the transmission.

I've found several resources on these transmissions - from tutorials on DIY rebuilds - to folks that will do a rebuild and ship it back.. so there's options... Just - none of them look fun.

(edit - later this evening after some more googling. Yeah - looks like my experienced symptoms are typical for a K46 that's worn out. I'm okay with doing a rebuild if I have to... - just not looking forward to it. )

Getting things put back together - and ready to torque down the bolt holding the electric clutch (55 ft lbs). How do you hold the flywheel to keep it from turning the engine while trying to torque that bolt? I'm not seeing a convenient (or any) place to jam a screwdriver or wrench - where I'm not going to risk breaking a flywheel tooth or something.

Maybe a few ugga-duggas with my air-impact and call it good? (I'd rather make sure it's torqued correctly)

EDIT - I found an old crescent wrench that I fed through the fan fins to hold the top bolt while torquing underneath.

The new belt & pulleys help. They'll buy me time to see about a rebuild kit later for the TuffTorq. About to put the deck back on - and clear up the space on my driveway before the city sends me a love letter about projects being left on the driveway. lol
