REPAIR INSTRUCTIONS

Disassemble:

1. Remove all bearing locknuts using spanner wrench.
2. Remove driveshaft. Due to cavity between the two bearing support areas, care should be taken to maintain alignment while removing.
3. Remove driven shaft in the same manner as above.

Reassemble:

1. Thoroughly clean all internal bearing locknut threads in housing.
2. Insert driven shaft.
3. Insert driveshaft. Note: Bottom front bearing on shoulder.
4. Thoroughly clean all bearing locknut threads.
5. Assemble bearing locknut on drive leg using Loctite screw lock #242 or equivalent. Note: Excessive sealant in threads may migrate to and cause bearings to seize. Snug bearing locknuts – DO NOT force. Excessive force will preload bearings and reduce life expectancy.
6. Assemble bearing locknuts to driven leg using thread sealant as above. Use locknuts to adjust and properly mesh gears.
7. Allow sufficient time for locknuts to seal then check using spanner wrench.
