Transmission drive failure.

Tool Type
Lawn Mower
Difficulty
Medium
Time
1-2 hours
Tools Used
Screwdriver, Pliers, Socket set, Wrench Set, Bench vice, punches, snap ring pliers, axle grease
Parts Used
Remove belt cover and cable and drive belt. Remove front wheels. Remove gear drives from each wheel by removing snap ring and washers. Remove height adjuster and wheel bearing. Remove belt pulley. Remove transmission cover and housing. Recommend careful inspection of bushing. Bearings and all hardware. Best to have a full tear down before placing parts order. Will probably need bushing and bearings when replacing ring and pinion. Remove axle, place in a vice and drive out pin using a punch. Do the same for the pinion bearing and wheel bearing if replacing. Be sure to pack new bearing with grease. Reverse everything to reassemble. Be sure to grease the transmission. Each wheel gear is stamped with a L and R. Pay attention or you get the drive direction reversed and you'll be taking it apart again.

Grinding noise in left wheel, loss of self propel function
Jim - July 24, 2016
Tool Type
Lawn Mower
Difficulty
Medium
Time
More than 2 hours
Tools Used
Screwdriver, Pliers, Socket set, Nutdriver, Adjustable Wrench
Removed back wheels, gears and axel.
Removed mower blade and belt.
Rebuilt transmission and repackaged with grease.
Reassembled and found an extra spacer. Eventually found it went in between the main engine shaft and the blade's shaft-bracket. If you leave this off then the engine won't turn due to clamping friction of the bracket against the engine's bottom.
After reassembling with all new parts and testing, the left wheel gears still sounded bad (grinding). Read different website forums from 2010-now where some people fixed this design/tolerance issue by adding spacers between the left wheel mount and the mower body. I added those and the grinding went away.
