PETROL TAP ADJUSTMENT
-
To make an adjustment, replacement or repair to either type of petrol tap the petrol
must be drained from the tank.
Push-pull
Type.
To adjust a leaking tap,
first
remove the grub screw locking the
plunger to the body, when the plunger assembly can be removed. Grip the plunger
end in a suitable tool and turn the plunger knob in a clockwise direction; this expands
the cork washer and will make a petrol tight
fit
when replaced in the petrol tap body.
If the cork has deteriorated to any degree, a new cork can be fitted at
a
very low cost.
Taper Type. Remove the faulty tap and dismantle; take out the split pin, remove
the washer, spring back plate and withdraw the spindle and lever assembly. Clean
the body and spindle and then apply a smear of fine grinding-in paste to the spindle,
add a little oil and rotate the spindle in the tap body using the same motion as when
grinding-in the valves. When a true surface
is
obtained, wash the pans thoroughly
in petrol and apply tallow fat to the spindle before assembly. Check the tension of
the spring and if insufficient stretch slightly.
FITTING A SIDECAR
(RIGID
FRAME
MODELS)
(also see Supplement)
First the motorcycle must be prepared for sidecar use.
Fork springs of the heavier
type must be fitted to counteract the additional load placed on the forks.
The extra load will make
it
necessary to reduce the gear ratios to obtain maximum
performance. To carry out this modification the engine sprocket should be changed
for one giving the gear ratios required (see Technical Data, pages
6
to
9).
Two sidecar fittings only are supplied by us, one fitting on the
rear
chain stays
immediately in front of the rear wheel spindle and the other at the front engine
plate ro frame bolts. These fittings are adaptable for nearly all sidecars; all other
fittings are obtainable from the sidecar manufacturers.
When the machine
is
prepared, attach the sidecar to the front and rear lugs and
tighten up the universal joints, but
not
the clip pinch bolts. Adjust the sliding
tubes through the lugs so that the sidecar
is
as close to the machine
a
possible:
this prevents excessive drag. Keep the front and rear tubes of the sidecar parallel
to
the ground and the nose elevated sufilciently to overcome any tendency to drag
when the outfit
is
taken round a right-hand bend at speed. The next point to
check
is
the amount of toe-in. To do this, two parallel aligning sticks are required
