This authentic item is supplied directly from the original equipment manufacturer for use with lawn mowers made by Toro and Lawn Boy. The transmission is made of metal and attaches to the bearing ball and the pivot bracket. When replacing this part a screwdriver, a set of pliers, a socket set, and a wrench set, may all be needed. This part is priced individually.
Place the mower on a pair of work stands so the the wheels are free to spin.

Remove the mulching door assembly from the mower deck.
Remove plastic grass clipping shield from the back of mower.
Remove the rear wheel assemblies using a socket.
Disassemble the rear drive gears from the axles, (Take pictures!) retaining all clips and shims in correct order. Drive gears are marked with an \"R\" on one side and are reversed from left and right side. Note the direction of free rotation and locked rotation!
Capture the ratchet pawl and spring from the axle as the gear is slid off.
Clean and re-grease all parts.
Remove 3 bolts each side that hold the rear drive axle side plates and slide off.
Lower the drive transmission/axle assembly and remove the metal belt retainer bolts from the transmission case after removing the torque spring. Remove belt and pull the transmission off of mower.
The tricky part now is to remove the pulley from the old transmission drive pinion. Its a self-locking nut and there is no easy place to grab the shaft to keep it from turning as the nut is removed. I removed the gearbox cover and held the drive gear.
Reverse the assembly procedure after cleaning and re-greasing all components.
This is also a great time to change oil, air filter and grease the front wheel axles.
