Timing Belt and Motor Replacement: R / RV Series Z and R Axes
NOTE: This procedure applies only 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 page3.
Remove the ZAxis Cover (R / RV Series Only)
1
a. Remove the 10 screws that secure the
Zaxis cover to the Zaxis module.
b. Carefully pull up vertically to remove the
Zaxis cover.
NOTE: Removing the four (4) screws near
the bottom of the Zaxis cover releases
the Zaxis bottom plate; place your hand
underneath the plate to catch it.
NOTE: The Zaxis module can be in
any position along the Xaxis during
maintenance.

2
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 screws only needs to be
loosened, not completely removed.
b. Remove the old timing belt from the idler
and timing pulley.

With the sawtooth sides of the new timing belt
facing one another, loop the belt around the
idler and timing pulleys.

Secure the motor fixing base to the Zaxis
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 Zaxis module.
NOTE: The tension is not measured for this
belt.

Replace the RAxis Timing Belt (R / RV Series Only)
5
Disconnect the following cables:
• Motor Z
• Motor R
• Sensor V (Raxis reversal optical switch)
• Sensor R
• Sensor Z
NOTE: All sensors must be disconnected to
allow sufficient movement of the Zaxis module
in future steps.

CAUTION
Risk of equipment damage or personal injury. The
Zaxis module is heavy and will fall if not held. A
second technician should hold the Zaxis module
during disassembly.
Release the four (4) screws that fasten the
Zaxis module to the robot assembly.
NOTE: If the wires for Sensor R, Sensor V, and
Motor R are connected to the Zaxis module,
the mobility of the module will be limited and
the following steps will have to be performed
with the module near the robot.

Tightly grasp the Raxis module and then
release the two (2) screws on the back side of
the Zaxis module to release the Raxis module.
NOTES:
• Releasing the Raxis module provides enough
mobility so the Raxis timing belt can be
removed from the pulley on the Raxis motor.
• The Raxis timing belt will be free but
constrained around the Raxis ball spline.

a. Slip the new timing belt around the Raxis
ball spline.
b. Move the ball spline back into position and
then tighten the black block set bolt to
secure it.
11
With the sawtooth sides of the new timing belt facing one another, loop the belt around the Raxis idler
and timing pulleys.
NOTE: The tension is not measured for this belt.
12
Secure the Raxis module to the Zaxis module with the two (2) screws removed previously.
13
Secure the Zaxis module to the robot with the four (4) screws previously removed.
14
Reconnect the Motor Z, Motor R, Sensor V (Raxis Reversal Optical Switch), Sensor R, and Sensor Z
cables.
