a) Clean the contact surfaces with solvent.
b) Apply a thin layer of grease to the plastic stop.
c) Loosely secure the contact group and the end of the connecting wire with two screws.
d) Check with a feeler gauge and adjust the clearance between the cam and the stop. Clearance: 0.45 mm.
7. Install and adjust the damper spring.
a) Apply grease to the damper spring bearing pad.
b) Loosely tighten the damper spring with the screw.
c) Check with a feeler gauge and adjust the clearance between the back of the cam and the spring.
- Gap: 0.05 - 0.45 mm.
8. Secure the connecting wire and terminal (connector).
a) Install the terminal and insulator.
