43. CLUTCH WORM LEVER,
ADJUSTMENT.
When further adjustment of the clutch
cable
is impossible or brings the clutch worm
lever into an unsuitable position, further
adjustment may
be obtained at the clutch
worm lever accessible through the oval cover
attached to the gearbox outer cover
by two
screws. This oval cover also forms an out-
rigger bearing for the clutch worm and is a
good fit in the outer cover. Should it be diffi-
cult to remove after the screws have been
withdrawn, it should be tapped round until
the ends stand away from the outer cover
and thus provide two lips beneath which
suitable levers may be inserted, but care
should be taken to avoid overstraining the
small cover. After slackening the cable adjuster
right down, the lever may be rotated on the
shank of the worm by releasing the pinch bolt
and holding the shank by means of the slot
machined across its end, whilst rotating the
lever in an anti-clockwise direction until it is
about 45° below the horizontal. Re-adjust the
cable as necessary and check that when the
clutch is withdrawn the angle between the
cable and the worm lever
is approximately a
right angle.
44. OUTER COVER, REMOVAL AND
FIT'flNG.
Remove the kick starter crank by releasing
its pinch bolt and pulling off the
crank.
