5.4.2 Drive Shaft Maintenance

Refer to the Model 6042 Legacy Owners/Operators

Manual for information regarding the lubrication of the

grease fittings on the drive shafts.

5.4.3 Drive Shaft Removal

IMPORTANT: To help ensure optimum performance, the

drive shaft assemblies are specially balanced as a unit at

the factory. When servicing any flange yoke, slip yoke or

drive shaft tube, order a complete assembly if compo-

nents are bent or damaged. Refer to the appropriate Parts

Manual for ordering information.

Note: The drive shaft assemblies are balanced

assemblies. Mark the yoke and axle, transmission,

transfer case, and the shaft and slip yoke so that these

components can be returned to their original positions

when reinstalled. Yokes at both ends of the drive shaft

must be in the same plane to help prevent excessive

vibration.

1. Level the vehicle, ground the carriage, place the travel

select lever in the (N) NEUTRAL position, place the

neutral lock lever in the (N) NEUTRAL LOCK

position, engage the parking brake switch and shut

the engine OFF.

2. Place an Accident Prevention Tag on both the

ignition key switch and steering wheel, stating that

the vehicle should not be operated. (Refer to Section
