1. Park the machine on a level surface, lower the cutting deck (or implement),
shut off the engine, set the parking brake, and remove the key from the
key switch.
Note: Because the clutch pulley and PTO pulley have different thicknesses,
check the pulley alignment at the pulley grooves.
2. Measure at the bottom of the pulleys, check that the clutch and PTO pulley
grooves are aligned within 1.5 mm (0.06 inch).
3. If the pulley grooves are not aligned within 1.5 mm (0.06 inch), loosen the
PTO bearing locking collars and move the PTO shaft to get proper pulley
alignment.
1. With the PTO belt installed, adjust the belt tension bolt until the compression
spring starts to compress.
2. Loosen and remove the set screws that secure the front and rear flange
bearing locking collars to the PTO shaft. Use the blind hole in each bearing
collar as a striking point, unlock the collars from the PTO shaft with a punch
by rotating the collars clockwise as viewed while facing forward.
3. Shift the position of the PTO shaft and pulley until the PTO pulley groove is
aligned with the clutch pulley groove.
4. Use the blind hole in each bearing collar as a striking point, lock the collars
to the PTO shaft with a punch by rotating the collars counterclockwise as
viewed while facing forward.
5. After you tighten the locking collars on the PTO flange bearings, check the
pulley alignment again to ensure that the alignment did not change.
6. Apply Loctite #242 to the locking collar set screws, install the set screws into
the collars, and torque the set screws to 9.6 to 11.3 N∙m (85 to 100 in-lb).
7. Adjust the PTO drive belt tension; refer to the Traction Unit Operator's
Manual.
