This Pinion Kit is used to allow NEO Motors to interface with the SDS MK4 Modules with the L1, L2, and L3 gear ratios.
If this kit is out of stock the following parts can be used as a substitute:
- One - am-0034
- One - am-0033
- One - am-1121
- A few - am-1009 (in sufficient quantity to put the pinion in mesh with the mating gear)
- One - am-3482
Pinion Installation:
The 15 Tooth 32DP pinion gear does not use a key for torque transfer. There are two possible methods of installation of this pinion on a CIM or NEO style motor.
- If the tolerances of both the motor shaft and the pinion are in your favor an arbor press (possibly up to 3 tons) is required to install this pinion due to the intended interference fit (0.001 - 0.002")
- If using an original NEO motor Please follow the NEO Press Fit Pinion Guide.
- If using a NEO 1.1 Motor insert a #10-32 x 3/8in long socket head screw into the hole in the back of the motor to support the internal shaft while pressing pinions
- If using a CIM or MiniCIM simply place the motor vertical on the arbor press taking care not to crush the wires, and press the pinion down the the desired location on the shaft.
- If the tolerances are not in your favor and the pinions slip on the shaft, or you feel that the press fit it too weak, an adhesive is required to transfer torque. The procedure is the same for all motors.
- Apply a few rings of red Loctite 271 to the shaft, and the bore of the pinion, then slip the pinion onto the shaft down the the desired location.
- Red Loctite 271 has been tested to a factor of safety of 4x the stall torque of a CIM when let to cure for 24 hours.
- Apply a few rings of red Loctite 271 to the shaft, and the bore of the pinion, then slip the pinion onto the shaft down the the desired location.
If you are are unable or uncomfortable performing these procedures, we recommend purchasing a motor with the pinion pre-installed. They are available as am-4258a_15T for the NEO.
