Setting Ring Gear Backlash

NOTE: Ring gear backlash is set at the factory. No
adjustment is required, unless the front cover is
replaced or the back lash pad screw is removed.
1. The backlash screw has locking agent that holds it into
place. Use a heat gun to lightly heat up the locking agent
on the screw.
2. Using a 3/32 hex wrench, turn the back-lash screw out 3-4
turns. Re-apply Loctite 262

3. Turn the screw in until it is lightly seated, then turn the
screw out 1/4 turn.
4. Set the gearcase upright. Rotate the input shaft at least 4
times. This ensures the ring gear completes one full
rotation.
5. If a tight spot is felt during rotation, loosen the backlash
screw another 1/8 turn. Perform the step 16 again. Repeat
this procedure until the pinion shaft rotates smoothly 4
times (1 revolution of ring gear).
