Slip Clutch Settings
WALTERSCHEID Manufacture (Belleville Spring)
Check the condition of the friction discs before use and following periods of storage.
Release the tension from the spring, turn the clutch while holding the P.T.O to ensure
hub is not seized to linings. (SEE BELOW):
Warning
The slip clutch is there to protect the gearbox. If the
blades strike a large obstacle they may get damaged or
break - avoid these conditions.
TO ENSURE PROPER CLUTCH FUNCTION AFTER LONG PERIODS ON INACTIVITY,
FRICTION CLUTCHES SHOULD BE RUN-IN TO PREVENT OXIDATION BUILD UP. THE
CLUTCHES ARE SET TO THE PROPER TORQUE SETTING FROM THE FACTORY, USING
THE FOLOWING PROCEDURE WILL PROVIDE THE MOST ACCURATE TORQUE SETTING:
1).
TIGHTEN THE FOUR NUTS ON THE INNER CIRCLE WITH A 13MM SPANNER. THE
NUTS SHOULD COMPRESS THE BELLEVILLE SPRING AND RELIEVE THE PRESSURE OFF
THE FRICTION DISCS IN THE CLUTCH.
2).
ROTATE THE SHAFTS BY ONE REVOLUTION, THIS CAN BE DONE BY RUNNING
THE MACHINE.
3).
RETURN THE FOUR NUTS TO THEIR ORIGINAL LOCATION AND ALLOW THE
CLUTCH TO COOL IF NECESSARY. NOTE: THE THREADS ON THE END OF THE STUDS
ARE DEFORMED TO PREVENT THE NUTS FROM BEING REMOVED.
