Place the mower on a pair of work stands so the the wheels are free to spin.
(I took pictures of all assemblies prior to removing for reassembly reference)
Remove the spark plug for safety.
Remove the blade from underneath using a socket or wrench.
Remove drive belt guard bolts from underneath and on top, remove g uard.
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.

Remove old axle assy. remove and install rear wheels on the correct side being sure to take a picture of the order of washers and thrust washers. You have to be sure to get the slip parts in the wheels on the right side. The biggest problem I encountered was a bolt broke on the belt guide. This is also one of the bolts securing the engine to the frame.Tried several eze-outs and managed to break a couple. Finally went ahead and drilled the hole out and installed a 3/8 bolt with a nylon lock nut. Start and test ran mower. Trans worked as designed.
