The gear change pedal, which is also spring loaded by a similar type spring returns the
pedal to the central position, after a gear has been selected, upon foot pressure being
released. An upward movement of the pedal engages first gear, a downward movement
causes engagement of higher gears.
Only a light, but deliberate pressure on the pedal is necessary, a jabbing or stamping
action on the pedal will result in damage to the operating mechanism.
When the gear pedal is moved the spring loaded pawl engages with the ratchet plate,
connected to the quadrant, by means of a large steel roller. Teeth on the quadrant
engage with teeth on the cam plate spindle, rotating cam plate in the direction desired.
The selector forks on a spindle are engaged in a profiled groove machined in the cam
plate causing the gears to shift, when cam plate is rotated.
The outer periphery of the cam plate, has notches machined in it, which engage with a
spring loaded plunger, thus positively indexing the gears when selected.
An indicator plate is mounted on the end of the quadrant spindle, to enable the gear
selected or neutral position to be identified.
TO REMOVE GEAR B O X OUTER COVER
Remove oil drain plug and drain off oil contents of the gear box.
Take off filler cap plate, disconnect clutch cable inner wire from operating lever, unscrew
cable adjuster and take out the cable.
Remove kick-starter crank, by releasing pinch bolt.
Remove foot change indicator plate by unscrewing bolt in foot change ratchet plate
spindle, leave the foot change pedal in position.
Remove five cheese headed screws securing outer cover.
The gear change pedal can be used to pull gently away the outer cover with care, to
avoid damage to the paper gasket. Should this gasket partly adhere to the outer and
inner cover during this process, separate the washer from the outer cover with the aid
of a penknife or similar tool
TO REPLACE GEAR B O X
OUTER COVER
Ensure paper gasket is undamaged, before
fitting cover. If foot change pawl spring is
removed, or displaced, it must be refitted
correctly as this spring is not reversible.
It will be observed that one leg on this
spring is straight, the other is cranked.
Correct location is with the straight leg o
the spring in the uppermost position.
Place the spring legs on each edge of
rocking pawl (see illustration 24), offer
up cover and replace parts in reverse
order described for removal.
TO REMOVE GEAR B O X
INNER COVER
Remove ratchet plate, with its spindle.
Remove clutch actuating arm and roller.
Remove lock ring securing clutch opera-
ting body, the body can be taken out—
watch for ½" steel ball.
Remove mainshaft nut, exposed when clutch operating body is removed.
Remove seven nuts securing inner cover to gear box shell.
The cover can now be removed with kick-starter axle in position, by gently tapping
behind the front end of the cover with care, to avoid damage to the paper gasket.
