RWD Lawn Mower Gear

thingiverse

Rear wheel drive gear for Toro lawnmower model 20332.Replaces the gear on P/N 138-3216 or 115-4695, not sure which (maybe both?).To remove the existing (old) drive gear, I used a 3/8" drill to partially drill out the heads of the studs (don't completely drill out the head!). Stop once the the stud gets a bit warm and starts spinning. Then pry up on the gear.The new gear was fastened in place with three 1/4"x1" lag screws. There will be a slight interference with the socket and the rib of the hub; either file this down or just push through with the socket.Update 9/1/2024 : Gear did hold up for a few mows. but ultimately stripped out. Not sure if the OD of gear is still maybe a little small or could have been that the metal drive gear this mates with was also worn and I did not replace that.
