1. Insert Tool A as a spacer that defines the distance to

the mounting surface.

2. Slide appropriate sized Sleeve over shaft all the way down to Tool A.

3. Slide Shaft Adaptor over Sleeve.

4. Use Tool C to press Shaft Adaptor over Sleeve (ensure Shaft Adapter

and Tool C spline alignment) until flush with Tool A.

1. Remove Tools A and C.

2. Place Base on motor, with Tool C used as a centering tool.

1. Fasten the Base on the motor (Tool C may need to be

rotated to allow for some mounting configurations).

2. Remove Tool C.

1. Make sure the snaps are fully engaged by pressing

on the Hub with the reverse side of Tool C.

2. When assembly is finished, the Shaft Adaptor, Sleeve

and Rotor Hub should all be flush with the Motor

Shaft rotating freely.

1. Snap the Top Cover onto the Base, carefully observing that the

teeth of the Shaft Adaptor align with the grooves in the hub. *

* We recommend no more than three cycles of mounting and

removal of the AMT top cover base. Multiple cycles of mounting

and removing the top cover can cause base fatigue over time and

affect encoder performance.

1. Align Tool C with flange on Base.

2. Slide Base and Tool C onto motor, centering onto

the Shaft Adapter.
