Install Drive Sheave
1. When gear stand is installed on mower, dimension
A (from the top of the mower deck to the center line
of the drive pulley) must be 2-1/16" (±1/32"). This is
a critical dimension and must be carefully adjusted
for proper belt life. Add or subtract shim washers
under idler pulley to align with drive pulley.
2. Tighten gear stand hardware.
3. Fill gearbox half full with SAE 90W gear lube.
4. Check level after waiting five minutes to permit
lube to work through bearings. Add lube, if
necessary, until gearbox is half full.
5. Replace driveline shield. Attach driveline to
gearbox.
