TO DISMANTLE A N D REFIT CRANKCASE RELEASE VALVE
IN CRANKSHAFT
(see Illustration 8)
DE-LUXE MODELS
Upon removal of the outer portion of front chaincase as described elsewhere, the release
valve will be observed on the end of the engine shaft.
On the De-Luxe Models this valve also retains the engine sprocket. Care should be
taken to avoid overtightening the hexagon body of the valve which screws on to the end
of the crankshaft.
STANDARD T W I N S (ALTERNATOR MODELS)
The release valve is in the form of a bolt to retain the rotor. Both valves consist of a
steel diaphragm (no spring) retained by a ring and peened on to the body making it a
sealed unit.
GEAR B O X LUBRICATION
Use one of the grades of Oils specified. In no circumstances must heavy grease be
used.
Lubricant is inserted through the filler cap orifice mounted on top edge of kick-starter
case cover.
The gearbox must not be entirely filled with oil. An excess will cause leakage. Check
the level every 1,000 miles and top-up if necessary.
A screwed drain plug in gear box shell, low down at rear, facilitates gear box flushing
and change of lubricant.
An oil level plug, adjacent to K.S. spindle, indicates maximum permissible oil level
(content 1 pint).
C H A I N LUBRICATIO N
The front driving chain runs in oil bath. (Front chaincase.)
Use engine oil to lubricate and maintain level to just below the chain inspection cap
orifice.
A sliding oil seal in the form of two steel discs surround the gearbox mainshaft.
To remove inspection cap use spanner 018178 in slot machined in the cap.
A drain plug is used so that oil can be changed without disturbing the outer portion of
the chaincase.
Rear driving chain should be removed occasionally for lubrication particularly under
winter conditions.
Clean chain in paraffin, allow to drain and wipe. Then immerse in one of the greases
recommended, heated to just fluid state. Leave in soak for at least ten minutes while
maintaining grease fluidity. Then hang to drain off surplus and replace.
Engine oil is a poor substitute for one of the recommended greases and if used the
chain should be allowed to soak for several hours to ensure penetration to all joints,
hanging to drain off surplus before re-fitting.
See chain removal and re-fitting instructions, page 55.
H U B LUBRICATION
Keep hubs packed with grease. This prevents entry of water and dirt. Grease nipple
accessible through hole in side hub disc. Inject small quantity of grease. Excessive
grease may impair efficiency of brakes.
