110. Camshaft.
The camshaft is shown in Fig. 69. If it is required
to remove one of the operating forks the operating peg
must first be withdrawn after removal of the split
cotter which secures it. When refitting the forks, note
that the one with the small forked end is fitted at the
end of the camshaft furthest from the operating gear.
Note also that the operating forks are assembled with
their forked ends next to each other. When replacing
the operating pegs make sure that they are the correct
way round as they are chamfered to clear the inside of
the gearbox casing.
111. Foot Change Mechanism.
This mechanism, though apparently complicated,
is actually quite simple in operation. The details of the
mechanism are shown in Fig. 70. The foot control
lever is mounted on the ratchet sleeve (5) and
movement of the lever turns the ratchet sleeve and
with it the control quadrant (4). During the first part
of the movement the pawl spindle (15) tips the
footchange pawl (16) until it engages in one of the
teeth in the ratchet (17). At the same time one of the
pawl springs (12) in the spring box (6) is compressed.
