Timing Belt and Motor Replacement: YAxis (continued)
14
Remove the two (2) set screws on the timing
pulley and then pull the timing pulley away from
the motor.
15
a. Assemble the timing pulley onto the shaft of
the new motor; align the timing pulley such
that the two (2) set screws contact the two
flat surfaces of the motor shaft.
b. Ensure that the distance from the base of
the timing pulley to the top of the motor is
4mm (0.16").

Place the new Yaxis motor into position and secure it with the four (4) screws removed previously.
17
Place the Yaxis timing belt around the timing pulley.
18
Repeat steps 9 and 10 of this procedure to
measure the tension on the timing belt and
observe the measurement displayed on the
meter:
• If the tension is within 50–70 N•m (37–
52ft‑lb), the tension is correct
• If the tension is outside 50–70 N•m (37–
52ft‑lb), adjust the timing belt adjusting kit
base screw again and repeat the tension
measurement. Repeat as needed until the
tension measures 50–70 N•m (37–52ft‑lb).
Reinstall the YAxis and Control Assembly Covers
19
Move the control assembly back into its position underneath the robot stage.
20
Place the control assembly cover on the back of the robot and secure it with the perimeter screws
removed previously.
21
Secure the control assembly to the control assembly cover with the screws removed previously.
NOTE: The quantity and location of the screws that secure the control assembly to the control
assembly cover differs for each robot model. Refer to “Control Assembly Cleaning” on page14 for
the control assembly cover screw locations.
22
Reinstall the Yaxis cover. Refer to “Reinstall the YAxis Cover” on page7 for detailed instructions.
23
Place the fixture plate on the Yaxis linear guideway plate and secure it with the four (4) screws
removed previously.

Timing Belt and Motor Replacement: ZAxis
NOTE: This procedure does not apply to R / RV Series units.
CAUTION
Risk of injury or equipment damage. Before performing any service procedure, complete the steps under
“Preparation for all Service Procedures” on page3.
Remove the ZAxis Cover
1
a. Remove the four (4) screws that secure the
Zaxis cover to the Zaxis module.
b. Pull up vertically to remove the Zaxis cover.

a. Release the four (4) screws on the motor
fixing base. This loosens the timing belt
enough to remove it from the idler and
timing pulleys.
NOTE: The screw only needs to be
loosened, not completely removed.
b. Remove the old timing belt from the idler
and timing pulleys.

Secure the motor fixing base to the Zaxis
module as follows:
a. Tighten the two (2) horizontal screws to
secure the timing belt.
b. Tighten the two (2) vertical screws to secure
the motor fixing base to the Zaxis module.
NOTE: The tension is not measured for this
belt.

With the sawtooth sides of the new timing belt
facing one another, loop the belt around the
idler and timing pulleys.
Align the sawtooth pattern of the timing belt so
it matches the pattern on the Zaxis module that
is covered by the timing belt fixing plate.

Adjust the motor to the upright position and
tighten the four (4) screws that fasten the motor
to the robot.
NOTE: The tension is not measured for this
belt.
