FRICTION CLUTCH MAINTENANCE
Friction Clutch Adjustment Procedure
To re-set the clutch to 1200 Nm, the gap between the Belleville Spring and the driveplate should be between
6.5 mm and 6.0 mm.
If a higher torque setting is needed, then tighten each bolt a 1/16 of a turn. One revolution of the nut will
compress the spring 175mm. Do not set the gap smaller than 5.5 mm. Measurements are approximate since
variations in spring force and friction materials may cause some differences in torque values. The clutch can
be adjusted with two 19 mm wrenches
Friction Clutch Seasonal Maintenance
To ensure proper clutch function after long periods of 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 following
procedure will provide the most accurate torque setting
Procedure:
1. Tighten the four nuts on inner bolt circle with either a 13 mm wrench or a 1/2” wrench. The nuts should
compress the Belleville Spring and relieve pressure off of the friction discs in the clutch.
2. Rotate clutch hub for at least one full rotation. This can be done either manually or by operating the
machine.
3. Return four nuts to the original location and allow the clutch to cool if necessary.
NOTE: The threads on the end of th studs are deformed to prevent the nuts from being removed.
