Instructions
- Press bearings in to plates so that flange is always on the the with out counter sinks.
- Using RC-2008-03-13 and RC-2008-03-11 attach the base attachment to the inner drive module plate (inner plate).
- Using RC-2008-03-12 fasten top stand off (RC-2008-03-11) to the inner plate.
- Mount motor with RC-2008-03-14. Position motor so that the wiring is coming out of the smaller removed corner.
- Place input gear on motor such that the hub is closer to the motor.
- Put output shaft in outer plate's bearing with hex side on the side with counter sinks.
- Place an e-clip on the groove outside the outer plate and immediately inside the outer plate.
- Put output gear on the output shaft (now in the inner plate) with the hub facing away from the outer plate.
- Add an e-clip to the last groove.
- Align the outer plate and then fasten it to the standoffs (already on inner plate) using RC-2008-03-12.
