E X H A U S T VALVE STEM LUBRICATION
From a drilling in the exhaust rocker axle boss in the rocker box, oil is fed to a cavity in
the cylinder head.
A further drilling from this cavity, through the cylinder head to an
oil hole in the valve guide, provides positive lubrication for this part of the engine and
needs no adjustment.
CRANKCASE RELEASE VALVE
Crankcase pressure is released into the atmosphere through a timed and ported release
valve. The ported portion for this valve is situated between the two driving side bearings,
the valve outlet is adjacent to the gear box housing. The valve cannot become deranged
and needs no attention.
GEAR B O X LUBRICATION
To top up or replenish oil for the gear box remove the inspection plate secured by two
screws on the gear box end cover.
Use one of the grades of oil specified, on no account must grease be used.
The normal oil content is 3 pints (1·8 litres), the gear box must not be completely filled
with oil.
After draining and replenishing the oil at the first 500 miles (800 kilometres)
top up every subsequent 1,000 miles (1,600 kilometres) to a level just below the bottom
of the orifice for the inspection plate.
FRONT C H A I N
The front chain is lubricated with engine oil filled to the front chain case, which forms
an oil bath.
If the lower of the two slatted screwed caps on the chain case is removed,
the oil level can be observed. The correct oil level is just above the bottom run of the
primary chain. To top up, remove both slotted screwed caps and fill Oil through the
uppermost aperture, checking the level through the lower.
immediately below the clutch assembly.
(·6 litres) of engine oil.
REAR C H A I N LUBRICATION
When a totally enclosed rear chaincase is fitted, the chain is lubricated by oil mist
discharged from the crankcase release valve tube on to the chain.
should not be necessary.
periodically particularly during wintry or prolonged inclement weather.
lubrication the chain should be removed, cleaned in paraffin (kerosene) and immersed in
grease that is heated until it becomes fluid.
C A U T I O N : When refitting the chain connecting link, the closed end of the spring
clip must face the way the chain travels.
WHEEL H U B LUBRICATION
Both hubs are pre-packed with grease during assembly, which prevents the entry of
water as well as lubricating the bearings.
:and before 10,000 miles (16,000 kilometres) dismantle and clean the hub bearings and
repack with fresh grease.
SPEEDOMETER LUBRICATION
Manual lubrication is not necessary, if a grease nipple is not fitted to the speedo-
meter gearbox.
REAR FORK HINGE (SWINGING ARM)
Apply grease gun on nipple mounted on the right side of the fork hinge, during routine
maintenance (use S.A.E. 140 oil).
REAR BRAKE PEDAL
A grease nipple is fitted underneath the pivot part of the pedal*
GENERAL
Occasionally apply a little engine oil to parts such as control levers, and cables, brake rods,
stands, etc.
Use a little grease to lubricate the twist grip rotor.
