Spring cartridge adjustment:
- Measure dimension L (Using a vernier caliper).
- Note : On first removal of the slip clutch, use Graph
below to determine measurement L. The measure L
will usually be found to be between 48.9 and 49.7 mm
(1.92’’ - 1.95’’).
- Adjust measure L to the required length.
By increasing the dimension L, the release effort
is reduced and vice versa.
