D14/4 LUBRICATION A6
FIG. A4.
CONTROL CABLES
Exposed sections of inner control cables should be
lubricated weekly with an oilcan. The most
satisfactory way of lubricating a cable, however, is to
include a flow of oil between the inner cable and the
casing by using a simple oil reservoir as shown in Fig.
A3, and leaving the cable for several hours.
During their manufacture, the inner cables are
greased with a molybdenum-based grease which forms
a semi-permanent lubricant and should therefore give
long service before needing attention.
SPEEDOMETER CABLE
It is necessary to lubricate the speedometer cable to
prevent premature failure of the inner wire, though
care must be taken to avoid over-zealous greasing
which may result in the lubricant entering the
instrument head. To gain access to the inner wire,
simply unscrew the cable nut at the speedometer
gearbox, when the wire can be withdrawn. The grease
should be applied sparingly to the wire but the top 6"
(near the instrument head) must not be greased.
REAR SUSPENSION
Each of the two suspension dampers comprise a
telescopic damper unit and a coil spring. During their
manufacture, the damper units are sealed and therefore
require no attention whatsoever. If they are damaged
or become ineffective, they must be replaced.
NOTE:—Should the damper bushes become noisy
and squeaky do not lubricate them with oil. A small
quantity of hydraulic brake fluid will be found to be
most effective and will not harm the rubber bushes.
The swinging arm pivot is provided with grease
nipples and must be thoroughly lubricated every 1,000
miles.
CLEANING AND POLISHING
Regular cleaning and polishing will protect the finish
of the motor-cycle, and maintain it in the best possible
condition.
The enamelled parts of the machine must never be
dry cleaned as this would lead to a scratched and dull
surface, they should first be washed in warm water.
Do not use detergents. Tar spots should be removed
using a cloth moistened with turpentine.
After washing and drying the enamelled parts they
should then be polished with one of the well known
brands of car polish, obtainable from any good
accessory dealer.
All chromium-plated parts should be washed and
dried as described for the enamelled parts, and then
polished with a soft duster. Stains can be removed
with any well known brand of chromium cleaner. Do
not use metal polish, as this will ruin the plating.
The dualseat cover should always be cleaned with
warm soapy water, never use detergents or chemical
cleaners which might be harmful to the material.
The engine unit, hubs and spokes using any well
known oil and grease solvent. Take care when
applying and washing off the solvent to avoid the
possibility of water entering the carburetter or
electrical equipment.
