- Broach a 3/32" keyway in the worm rear ID
- Drill the output shaft bushing holes on the worm gearbox to 3/8" (from 8mm)
- Replace output shaft bushings with 0.25" ID bronze flange bushings (1/2" long)
- Cut (3) 3/32" keys: for worm gear and (2) for Hubs
- Assemble output worm gear and shaft w/ key
- Re-assemble input shaft with dual motors and worm
- Bore (2) driven Hubs to 0.250" ID and broach 3/32" keyways
- Reassemble arm drive shaft (including tubing portion)
