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.

Use a 12 mm wrench to release the black block
set bolt and then remove the black block from
the threaded section of the Raxis ball spline.
9
Move the Raxis ball spline down and then
remove the old timing belt.

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.

15
a. After the timing belt is fastened and all
cables are reconnected, release the two (2)
screws that attach the Raxis ball screw and
the Raxis motor shaft.
b. Power on the robot and adjust Sensor V and
Sensor R until their sensor lights are blocked
simultaneously.
c. In that position, re‑tighten the two (2) screws
that secure the Raxis ball screw and the
Raxis motor shaft.

Switch off the robot power before continuing to the next procedure.
Replace the ZAxis Motor (R / RV Series Only)
17
Go to “Replace the ZAxis Motor (All Units Except E2 / E2V and R / RV Series)” on page27 to
replace the Zaxis motor. Return here to continue.
NOTE: The only difference for the R / RV series is that the timing belt is angled as it exits the timing
pulley; this does not alter the motor replacement process.

18
Complete steps 5–7 of “Replace the RAxis Timing Belt (R / RV Series Only)” on page30 to release
the Raxis module. Return here to continue.
19
Release the two (2) screws that attach the
Raxis ball screw and the Raxis motor shaft
and push the coupling up.
