- Loosen over-center preload adjuster. Tighten worm bearing adjuster until all end play has been removed; then loosen 1/4 turn and tighten lock nut. Turn worm shaft carefully to either stop. Do not jam into stop as damage to gear could result. Rotate worm shaft back from stop about 1/2 turn.
- Using an INCH lbs. torque wrench, measure the torque required to keep worm shaft in motion about one revolution. Adjust rotating torque with worm bearing adjuster. Tighten lock nut, and recheck turning torque. Adjust as necessary. Perform over-center preload adjustment procedure.
