NOTE:
The stop should not bind against the spring
clutch when the adjustment is made.
CAUTION:
Be sure the cam is detented at the time the
stop adjustment is checked.

Shift Cam Brake Adjustment
Excessive braking action could prevent the cam from
reaching the detented position in the lower case. Insuf-
ficient braking action would result in a noisy shift oper-
ati on and expose the mechanism to possible parts break-
age.

With the shift interlock on the high point of the cam,
adjust the interlock by its adjusting screw so that the
tip just bottoms between two teeth on the shift clutch
ratchet (Fig.

Shift Interlock Cam - With the cycle clutch latched at
rest and the backlash of the cycle shaft and fi Iter shaft
removed in the operating direction, advance the cam
until a clearance of .040

to .060" exists between the
tip of the interlock and the top of a tooth on the shift
clutch ratchet (Fig. 33).

This clearance insures free operation of the armature.
With no clearance and oi
