Step 4: Insert FR8ZZ Bearing into Shaft Plate.
Step 5: Slide the Shaft Plate and FR8ZZ Bearing onto the Output Shaft. This will be a
tight slip fit. The four locating nubs on the Housing will line up with the four location
holes on the Shaft Plate.
Step 6: One at a time, install 4 Nylock Nuts in the hex pockets on the back side of the
Housing. Screw a 10-32 x 5/8” screw into each nut.
Tip:
Use an arbor press, or tap
lightly with a wood block (to
a oid damage to the bearing).
Tip:
Be sure that the FR8ZZ flange is
inside of the housing. If it is on
the outside of the plate, this
bearing will e entually fall out.
Tip:
You won’t need a wrench to
hold the nut. Just hold it into
the pocket with your finger as
you are dri ing the screw with
a 5/32” allen dri er.

Step 7: Insert the 2x2x10mm Machine Key onto the CIM Motor keyway. Then, slide on
the 12x520 CIM Gear so that it almost touches the motor. Lastly, press on the 5/16”
Retaining Ring onto the motor shaft to keep the CIM Gear in place.
Step 8: Slide the CIM Motor into one of the two motor locations on the back side of the
Housing. Use two 10-32x5/8” Screws to fasten the motor in place.
Step 9: Place the 1/8x1/8x0.7” Machine Key into the 1/8” wide keyway on the Output
Shaft. Don’t keep it there, since you won’t really install this machine key until you put
the sprocket on the Output Shaft. Use the ¼” Washer and Button Head Screw to
capture the sprocket on this shaft (eventually).
Tips:
The retaining clip has small tongs on its interior.
Line up one of these tongs to fit into the keyway,
and the machine key won’t back out.
Use a 3/8” socket dri er to push the retaining
ring into position.
