The other point of adjustment is behind the
lower inspection cover on the front of the
gearbox and is for compensating for wear on the
clutch plate inserts. To make the adjustment,
remove the inspection cover, slacken the locknut
and turn the
Section E1 Page 4
and turn the central screw. Tighten the locknut
after adjustment has been made.
The reason for the two points of adjustment is
to enable the lever behind the cover to be kept in
its proper position whether the need for
adjustment is caused by plate wear or cable
stretch.
Owing to initial bedding down of the clutch
plate inserts, the clutch control may require
adjustment after the first few hundred miles with
a new machine. This point should therefore be
examined soon after delivery and adjustment
made if necessary.
On earlier models the clutch operating
mechanism is exposed on the front of the
gearbox, but the adjustments are, however, the
same in principle as those described above.
The cable adjustment is at the bottom of the
front of the gearbox just in front of the kickstart
lever. The collar is screwed in or out of a lug on
the gearbox cover and is secured by a locknut as
before.
The other adjustment is made by slackening
the clamping bolt in the horizontal lever and
turning the lever on its spindle, which is the end
of the operating worm in the gearbox cover.
When correctly adjusted, the lever should be
approximately square with the cable when the
clutch is fully lifted.
The position of the lever endwise on the
worm spindle is important and it should be
positioned so that it does not foul the kickstart
lever.
8. Adjustment of the Neutral Finder
The neutral finder is adjusted by means of an
eccentric stop secured to the front of the gearbox
cover by a bolt which limits the travel of the
operating pedal. Slacken the bolt and turn the
eccentric stop until the correct movement of the
pedal is obtained.
9. Gearbox Oil Level
The gearbox is replenished with oil by
removing a plug in the top and the correct level
can be checked by removing a second plug lower
down on the right hand side looking at the cover.
On earlier models a dip-stick is attached to the
filler plug for measuring the level of the oil or
was provided loose in the tool kit.
On some models the filler plug is on the side
of the gearbox and in such cases the oil should be
level with the plug hole and no dip-stick is
required. The oil will be found to run into the box
more easily on these models if the engine is
started up and allowed to tick over so that the
gears and shafts rotate.
