Rear Chain Adjustment
Adjustment of the rear chain involves moving the rear wheel and is described on
page 27.
Clutch Control
The clutch adjustment will be found at the left-hand end of the gearbox mainshaft
(see Fig. 7) and it consists of an adjusting pin
C
screwed into the clutch withdrawal
sleeve and a locknut
B
to secure it in position. These items are accessible through an
aperture in the outer cover, after removal of the rubber cap, or by removal of the
complete outer cover. The adjusting pin presses against the clutch withdrawal rod
with a steel ball interposed and the withdrawal mechanism must at all times be so
adjusted that there is a slight amount of play between the pin, the steel ball, and the
operating rod, in order to ensure that the clutch springs may exert their full pressure
on the driving and driven plates. If there is not sufficient play there will be a
tendency for the clutch to slip continually owing to reduced spring pressure, and this
in turn will cause over-heating and serious damage to the clutch itself.
