Step 1: Axle

Align the axle’s socket with the motor’s square drive shaft and press-fit it into place.

Although the axle is precision machined to fit with the motor shaft, sometimes the axles will slide on

effortlessly, or they may require a very gentle tap from a non-steel hammer to seat them as shown

below. This is due to manufacturing tolerances on the motors.

When you first put the axle on the shaft it may seem loose and wiggle around a bit…this is normal. Once

you install the block and screws the wiggle will almost entirely disappear. This is well within the drive

system and encoder’s resolution design parameters.

When the drive shaft is all the way on the motor drive pin, it should look like this. The distance between

the motor housing and the large end of the axle should be approximately one-tenth of an inch.

Gap should be

0.1 inch

(2.5 mm) wide
