Refer to Figure 3-10., Swing Motor Removal and Installation.
1. Thoroughly clean the area around the swing motor to
prevent any dirt from entering the system.
2. Tag and disconnect the hydraulic lines running to the
swing motor. Cap or plug all openings.

when removing the swing motor. Failure to do so could
damage the worm gear seals.
