Backlash Pad (Thrust Pad) Adjustment

1. Lay the gearcase on the side with the output cover facing
up.
2. The backlash screw has Loctite applied to it. Use a heat gun
to lightly heat up the Loctite on the screw (A).
3. Using a hex wrench, turn the back-lash screw out 3-4 turns.
Re-apply red Loctite onto the bottom screw threads.
4. Turn the screw in until it is lightly seated, then turn the
screw out 1/4 turn.
5. Set the gearcase upright. Rotate the pinion shaft at least 4
times. This ensures the ring gear completes one full
rotation.
