control quadrant (4) causes the ratchet (17) to move,
carrying with it the control sector quadrant (18) and
gear sector (19) which thus turns the gear on the end
of the camshaft (see Fig. 69). At the same time the
spring box (6) itself pivots, compressing one of the
main springs (11) until further movement of the
control lever is prevented by one of the stops formed
on the spring box. On releasing the control lever the
springs in the spring box return the box, control
quadrant and pawl to their normal positions, but
movement of the ratchet, control sector quadrant, gear
sector and camshaft is prevented by the gear indexing
pawl which engages with grooves cut in the camshaft
(Fig. 69). Thus on the return of the pedal the pawl (16)
slides over one of the ratchet teeth and is ready to pick
up the next tooth when the control lever is operated
again.
The sector spindle (3) moves with the control
sector quadrant (18) and carries on its outer end the
gear indicator, the position of which thus indicates
which gear is engaged. Note that this gear indicator is
in line with the small fixed indicator when the gears
are in neutral.
112. Kickstarter Mechanism.
This is shown in Fig. 71. Operation of the lever
(6) rotates the quadrant (10) which engages with the
ratchet pinion (20 in Fig. 66) and rotates the engine
through the driving ratchet, mainshaft, clutch and
primary chain. When the engine starts, the ratchet
pinion over-runs the driving ratchet until the kickstart
lever is returned to its normal position, when the
quadrant disengages from the ratchet pinion and
allows the pinion to rotate with the mainshaft and
driving ratchet.
It is important to make sure that the kickstart
lever is returned fully home so that the quadrant is
disengaged from the ratchet pinion, otherwise the
latter may seize on the mainshaft and do a
considerable amount of damage. If the kickstart
spring is broken or weak, pick the lever up by hand
and place it in position so that the kickstart lever
spring clip (5) will hold it in place. Early boxes were
not fitted with this spring clip, but should have been
modified in service.
