Removing and Installing the PTO Shaft
IMPORTANT
To maintain correct shaft balance, clearly mark the PTO shaft across
the slip shaft and the slip tube prior to disassembly.
1. Remove the cutting unit from the machine; refer to the cutting unit Operator’s
Manual .
2. Remove the 6 cap screws from the PTO shaft flange at the PTO clutch and
remove the shaft from the machine.
3. When installing the PTO shaft flange at the PTO clutch, apply medium
strength thread locking compound to the cap screws and tighten from 18 to
21 N·m (155 to 185 in-lb) in a star pattern.
4. Install the cutting unit to the machine; refer to the cutting unit Operator’s
Manual .
5. Lubricate the PTO shaft grease fittings before returning the machine to
service; refer to the Traction Unit Operator’s Manual .
IMPORTANT
Ensure that the markings on the slip shaft and slip tube are aligned
when the PTO shaft is assembled. Misalignment of the shaft and
tube will result in shortened shaft bearing life and may cause
unnecessary vibration during cutting unit (or implement) operation.
