trouble-free operation.
Put the machine in
Safe Condition
before working on this machine:
•
disengage the PTO
•
shut off the engine
•
ensure all components have stopped moving
•
remove and pocket the ignition key
•
block & chock the wheels
•
set rotor lock if required
7�2�1 DRIVELINE MAINTENANCE
The PTO drive line is designed to telescope to allow for dimensional changes as the machine goes through
its operational range.
A heavy duty plastic tubular guard encloses the driving components and is designed to turn relative to the
driving components.
The drive line should telescope easily and the guard turn freely on the shaft at all times. Annual disassembly,
cleaning and lubrication is recommended to insure that all components function as intended.
Ensure that the universal joints are lubricated, inspect and lubricate every 8 hours.
When reassembling the driveline, ensure that the driveline is assembled "in phase", to avoid unnecessary
vibration when the machine is running.
7�2�2 SHEAR PIN:
The PTO drive line is designed with a shear pin at the input yoke to prevent overloading the drive system.
Remove the broken parts from the yoke when the pin shears and replace with genuine Wallenstein parts.
The drive system is designed to function well without failing the shear pin. If it does fail, generally it is
being fed too fast or something very hard has been jammed into the rotor or between the blades. Always
unplug the system and determine the cause of the problem and correct it before resuming work. Shear pin
replacements are available from your dealer
