Removal (Fig. 60)
1. Park machine on a level surface, lower cutting deck
(or implement), stop engine, engage parking brake and
remove key from the ignition switch.
2. Support drive shaft to prevent it from falling.
3. Disconnect front yoke flange of drive shaft from front
axle flange by removing six (6) socket head screws and
lock washers.
4. Disconnect rear yoke flange of drive shaft from bi-
directional clutch by removing six (6) socket head

Installation (Fig. 60)
IMPORTANT: If the drive shaft tube and shaft were
separated, make sure that the drive shaft yokes are
aligned when the tube and shaft are assembled (Fig.
60). Misalignment of the yokes will result in short-
ened drive shaft life and will cause unnecessary
vibration.
1. Position rear axle drive shaft to machine. Make sure
that drive shaft tube (item 10) is toward rear axle.
2. Secure yokes of drive shaft to front axle flange and
bidirectional clutch with removed fasteners.
3. Lubricate drive shaft grease fittings (see Traction
Unit Operator’s Manual).
