Instruction manual

GEAR BOX LUBRICATION

Use one of the grades of Oils already 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 gear box must not be entirely filled with oil, and, under normal conditions, the

addition of two fluid ounces of oil every 1,000 miles will be sufficient.

Excessive oil will cause leakage.

A screwed drain plug in gear box shell, low down at rear, facilitates gear box flushing

and change of lubricant.

HUB LUBRICATION

Keep hubs packed with grease. This prevents entry of water and dirt. Grease nipples

in centre of hubs. Inject small quantity of grease. Excessive grease may impair efficiency

of brakes.

CHAIN LUBRICATION

Front driving chain and dynamo chain run in oil bath. (Front chaincase.) Use engine

oil. Maintain level to height of the inspection cap opening.

Oil in front chaincase also lubricates the engine shock absorber. Transmission harshness

generally indicates level of oil in chaincase is too low.

Remove chaincase inspection cap each week, inspect level of oil, top-up as necessary.

To remove inspection cap :—

Unscrew knurled screw about four turns.

Slide cap sideways, till the back plate can be slipped through the opening, and take away

the complete cap assembly.

When replacing inspection cap, centralise cork washer and then fully tighten knurled

screw. Essential this is kept tight otherwise cap assembly will be lost.

Rear driving chain should be removed for lubrication. Clean chain in paraffin, drain

and wipe. Immerse in bath of molten tallow, leave for several minutes, remove and

allow excess lubricant to drain off and then replace on machine. Engine oil is a poor

substitute for tallow and, if used, chain should be allowed to soak for several hours.

Lubricate rear chain every three thousand miles in Summer and every thousand miles in

Winter.

Magneto chain runs in case packed with grease. A grease nipple is fitted to the case

cover. Inject small quantity of grease every thousand miles.
