Spring cartridge adjusment:
- Measure dimension L (Using a vernier caliper).
- Note measure L in the box (only when removing clutch
for the first time). The measure L is generally
comprised between 51.7 and 52.5 mm (2.03’’ - 2.06’’).
- Adjust measure L to the required length.
By increasing the dimension L, the release effort
is reduced and vice versa.
