Dynamo

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 (1600 kilometres) to a level just below the bottom of the orfice for the inspection plate. Front chain lubrication. 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 slotted 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. A drain plug is situated immediately below the clutch assembly. If the chaincase is drained, refill with 1 pint (.6 litres) of engine oil, Rear chain lubrication (exposed chain). The rear chain should be removed occasionally, particularly during wintry or prolonged inclement weather, for lubrication. The life of this chain will be prolonged if it is lubricated effectively and not allowed to run in a dry condition.

With the chain removed, scrub the side plates with a wire brush then wash in paraffin (Kerosene). Use a small quantity of one of the recommended greases in a flat tin and heat until the grease is fluid. Immerse the chain and re-heat the grease, which will cool off. Soak for ten minutes, take out the chain, wipe off surplus grease and refit, Caution: When refitting the chain connecting link, the closed end of the spring clip must face the way the chain travels. Wheel hub lubrication. Both hubs are pre-packed with grease during assembly, which prevents the entry of water as well as lubricating the bearings. After the first 5,000 miles (8000 kilometres) and before 10,000 miles (16000 kilometres) dismantle and clean the hub bearings and repack with fresh grease. Speedometer lubrication. A grease nipple is fitted to the speedometer gear box which is attached to the right side of the rear wheel. Use grease sparingly, no other part of this equipment requires lubrication. 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.

RECOMMENDED LUBRICANTS

Efficient lubrication is of vital importance and it is false economy to use cheap grades of oil. When buying oils or grease it is advisable to specify the brand as well as the grade and, as an additional precaution, to buy from sealed containers. ENGINE Ambient temperature above 50°F.
