bryananddarla , Info from Replacement parts link below, on changing the gear..

Use 13mm socket to remove wheel. Determine it the gear on the mower is worn. Check both wheels to determine if you need to replace the gear on both sides! If you don't you'll end up ordering twice and paying for shipping twice. Also the same gear works on both sides and is marked with an R and L so you will know how to put it on.

Remove c clamp with screwdriver and pliers. Don't bend it. Just press down on the clamp until you can get a grip on it with the pliers and then pull it off.

Remove the washer

Remove the worn out gear. Don't let the little free moving metal tab that engages the gear slip out of its slot or the wheel will not engage when you finish.

Put the new gear on. It has an R on one side and an L on the other. The R goes on the right side as you stand behind the mower, L on the left side.

Reverse the process for the washer and c clamp.

Replace the wheel.

Many Thanks - the part took about 3 minutes to install thanks to these clear directions. The personal pace system now works much better.

Please answer this question. When looking at the pinion gear on the right rear and you have the gear on the axle should the R be visible?

Dino Jacovides, I believe the R should be visible on gear(facing out) for right side pinion gear install.
