Had to remove wheels,belt cover and blade to replace key springs, new belt and lube rear wheels after cleaning said parts.
I would never do this job as shown in tutorial and feel it's necessary to remove both wheels ,blade belt shroud and rear wheel holders and use new washers and bearings to give the job more/longer service.

Time

Tools Used
Screwdriver, Pliers, Socket set, Gloves
1. Disconnected spark plug. Removed grass bag. Raised mower up on wooden 2x4s to access back wheels (did not tilt mower).
2. Removed left wheel with a socket set.
3. Removed ring clip with screw driver and needle nose pliers.
4. Removed pinion gear and thrust washer while holding down key on shaft. Quickly examined condition of key and didn't replace.
5. Replaced with new pinion gear, new thrust washer and new ring clip. Slid pinion gear on with L on outside (facing direction you would be standing to use mower), thrust washer and put on gloves to push ring clip onto shaft. The pinion gears have L and R engraved on them and are interchangeable.
6. Replaced old wheel with new wheel. Gears on old wheel were worn too. Used socket set to reinstall wheel.
7. Repeated for the right side.
8. Tested and self propelled worked. Although the left wheel would not move when I backed up. I had the tension too tight on the self propelled cable. Loosen nut near handle and eased back on the tension in the cable. Mower backs up and self propelled works like new. Mower is about 12-14 years old and is a Toro Personal Pace.
2. Removed left wheel with a socket set.
3. Removed ring clip with screw driver and needle nose pliers.
4. Removed pinion gear and thrust washer while holding down key on shaft. Quickly examined condition of key and didn't replace.
5. Replaced with new pinion gear, new thrust washer and new ring clip. Slid pinion gear on with L on outside (facing direction you would be standing to use mower), thrust washer and put on gloves to push ring clip onto shaft. The pinion gears have L and R engraved on them and are interchangeable.
6. Replaced old wheel with new wheel. Gears on old wheel were worn too. Used socket set to reinstall wheel.
