WARNING
The secondary clutch helix is equipped with a spring. For
safety use the tool indicated above when dismantling.
CLEANING
Large bushing and small bushing
During the break-in period (about 10 hours of use) the teflon of
the bushing moves toward the surface of the helix or of the
shaft. The result is a light, constant friction of teflon against
Teflon, so it is normal to note a coating of grey teflon on the cam
or on the shaft. Do not remove this coating; it is not dust.
When it is necessary to remove a coating of dust from the cam
or from the shaft, use a dry cloth to avoid removing the teflon
that has been deposited there.
Cleaning the sheaves
Use Loctite Safety Solvent (P/N 413 7082 00).
INSPECTION
Bushings
Make sure there are no cracks or scratches on the bushings and
that they can move freely when installed on the fixed sheave.
Using a bore dial gauge, measure the diameter of the bushing.
These measures must be taken at least 5mm (1/4 in) from the
edge of the bushing.
