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 backlash screw has been tampered
with.
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 an Allen wrench, turn the backlash screw out 3-4
turns. Re-apply Loctite 262
threads.

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 and perform step 4 again. Repeat
this procedure until the pinion shaft rotates smoothly 4
times (1 revolution of ring gear).
