You have to remove the drive gear and adjustment plate to get to the retainer bushing. Because it is probably rusted on, you will need to use a very large wrench or a vise and hammer if you do not have the right size wrench. After you get it part reassembly is very easy.

Drive wheels sloppy causing premature drive & pinion gear wear
Stephen - June 9, 2020
Tool Type
Lawn Mower
Difficulty
Easy
Time

Tools Used
Socket set, Snap ring Pliers
The original bearings were totally worn out, the plastic sleeves were gone completely, the rear wheels were moving around and causing the gears inside the wheel to misalign and grind and wear out quick. I replaced the bearings and bushings to get rid of the slop, the bearing retainer just made the job easier so I could replace the assembly and did not have to remove the old bearing. It goes together just like the parts drawings on the website. I had already replaced the wheels/drive gears and pinion gears prior and that did not solve my problem. Mower is 9 years old and now nice and smooth just like new for around $45 (I have to give youtube a little credit)

Socket set, Wrench Set, Snap ring pliers.
Removed the wheel and the pinion and bearing housing. Pressed the new bearing into the new bearing housing and then then pressed in the fiber sleeve into the bearing housing. Install the new bearing housing into the wheel bracket. Installed the pinion spacer washer and then the pinon gear. and installed the snap ring retainer.
Installed new wheel and axle bolt with the new spacer washer. Note: I had just installed a new pinion gear a few days before.
Works ok so far. No pinion gear jumping on the wheel gear. Suspect the bearing and the fiber sleeve for the drive shaft from the transmission was worn causing the skipping problem on my Toro personal pace mower.

I pulled the rear wheels of and the handle mount to expose the bearings and sleeves.
I unscrewed the old retainer bushings.
I pressed the bearing and bush sleeve into the retainer bushing using the bench vise. this made it very easy.
I put the retainer bushings back in place and put it back together.
The mowers self-propels quietly and quickly.
