Removal
CAUTION
If the Process Drive is being reinstalled, pin the gears using the holes provided in the Process
Drive frame (Figure 1) to maintain gear alignment. Use a paper clip or similar object to pin the
gears before removing the drive. Replacement drives have pins installed. Do not remove these
pins until the drive has been installed. Installation of the Process Drive with misaligned gears
can damage the system. See Figure 1 to verify proper gear position before replacing the
screws.

Wiper Assembly in the home position.
CAUTION
Seat all 3 mounting screws before torquing the screws to final tightness (12 in-lbs.). Tightening
the screws individually before seating all three can put undue strain on the mounting bosses.
