ADJUSTING CLUTCH RELEASE MECHANISM
Loosen clutch release rod adjusting screw locknut (6) and
back off (counterclockwise) clutch release rod adjusting
screw (7). Clutch release worm (4) inside transmission
sprocket cover (2) should seat against its stop (13) when
clutch hand lever is in its fully extended position. If lever
does not fully seat, check to see if cable is binding in housing.
Adjust cable length byturning clutch cable adjusting sleeve
(hand lever end of cable housing) so that clutch releasing
worm does not quite return against its stop. This will hold
clutch hand lever in its fully extended position at all times.
Turn clutch release rod adjusting screw (7) inward until
clutch hand lever has 1/8 of its full movement free before
clutch starts to release. This can be checked by a slight in-
crease in tension on the clutch hand lever as it is being
moved to the released position. Tighten clutch release rod
adjusting screw locknut (6), without disturbing the setting
of the adjusting screw.

will not be oil-tight when reassembled.

and sixspring adjusting nuts are in view. Three of the spring
tension adjusting nuts (5) have 7/16 in. hex heads and
three nuts (6) have 1/2 in. hex heads. All spring tension ad-
justing nuts are recessed to conform to raised portion of
spring tension adjusting plate which provides a lock for the
Tighten each of the six nuts one half turn at a time. The nuts
must always remain in their locked positions after adjustment is made.
Tightening the spring tension adjusting nuts moves the
spring tension adjusting plate (7) closer to the outside surface
of the clutch releasing plate (10). The inner surface of
the spring tension adjusting plate should measure 3/16 in.
