460 Slip Clutch Maintenance & Settings
BONDIOLI 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
stationary. Adjust the spring compression to the original setting.
Following seasonal use, unload the spring tension and stone clutch assembly in a dry
place. Check condition of friction linings and reset spring compression to original
height before use.
Should the assembly overheat due to frequent or prolonged clutch slipping, dismantle
for inspection. The original thickness of the lining is 3.2mm, replace them when worn
to 2.5mm. Clean up all contact surfaces and replace any damaged components
before assembly.
