Driveline – clutch-adjustment. Bondioli
1. 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. Or slip it using the tractor for it. (On 730, first
slip the outer clutch, then the inner). Adjust the spring compression to the
original setting.
2. Following seasonal use, unload the spring tension and store clutch
assembly in a dry place. Check condition of friction linings and reset
spring compression to original height before use.
3. Before season. See issue 1.
4. Should the assembly overheat due to frequent or prolonged clutch
slipping, dismantle for inspection.
The original thickness of the lining is 3.2 mm, replace them when worn to 2.5mm
or when overheated. Clean up all contact surfaces and replace any damaged
components before assembly.
