Shaft Removal
1. Level the vehicle, ground the attachment, place the
travel select lever in NEUTRAL (N) and engage the
neutral lock lever, engage the parking brake switch
and shut off the engine.
2. Remove the ignition key. Secure accident prevention
tags to the steering wheel and ignition key switch.
Refer to Section 1.5, “Accident Prevention Tags.”
3. Disconnect the negative (-) battery cable (1).
4. Remove the drive shaft (3) from between the engine

drive shaft, remove the capscrews (4) and straps (5)
holding the drive shaft to the transmission yoke (6).
Discard both straps and capscrews.
5. Remove the capscrews and lockwashers (7) holding
the access cover plate (8) to the bell housing of
engine. Discard the capscrews and lockwashers. Let
the cover plate rest on the tube of the drive shaft (9).

removed, thread two of the capscrews into the two

Remove the bushing with the drive shaft attached
