FIG. B12.
The pegs in the cam plate and quadrant should be
secure and the dogs on the quadrant and the
corresponding claws on the selector plate should be in
good condition.
ATTENTION TO FLYWHEELS
Whilst at this stage it is advisable to check the big-end
for signs of wear. Hold the connecting rod at its
highest point of travel and try gently but firmly to
push and pull the rod in the direction of travel. If the
big-end is sound there should be no play in this
direction though it may be possible to rock the rod
sideways. The sideways play is permissible provided
the connecting rod does not catch on the flywheels at
any point, but if any vertical play is detected it must be
decided if the amount is permissible or not.
The bearing is of ample dimensions for the work it
has to do and, provided that the engine has been
carefully used and adequately lubricated, the bearing
is unlikely to need replacement.
If the bearing has noticeably deteriorated as the result
of neglect or abuse, the flywheels must be parted to
gain access to the bearing.
The flywheels are a press-fit on to the ends of the
crankpin and no attempt should be made to part them
unless the services of an expert mechanic and a fully
equipped workshop are available.
To part the flywheels first place the assembly in the
bolster and position the stripping bars as shown in Fig.
B13. Using the punch, drive out the crankpin and take
off the uppermost flywheel. Reverse the assembly in
the bolster and again drive out the crankpin, releasing
the other flywheel.
To reassemble the flywheels, place the left-hand
flywheel into the bolster and, using a suitable hand
press, insert one end of the new crankpin.
