Norton Commando Workshop Manual

## Routine Maintenance

# K

Run the engine for three minutes, then stop the engine and allow the oil to settle in the tank for a further two minutes. Recheck the oil level and top up as required. Finally, refit the side panel (where applicable).

A coarse mesh metal filter is incorporated with the oil feed pipe fixing bolt. This should be cleaned at 2,500 miles intervals and when the oil is changed.

### SECTION K6

### GEAR BOX OIL LEVEL

An oil level plug is fitted in the gearbox cover (see Fig. K5).
To check level, remove plug (see Fig. K5, item B) whereupon oil should seep gently out if level is correct. If topping up is necessary, remove the filler cap (see Fig. K5, item C) and replenish with correct grade of oil until the oil begins to seep from the level plug orifice. Replace the filler cap and the level plug.

### SECTION K7

### GEARBOX OIL CHANGING

The gearbox oil should be changed after a run so that the warm oil flows more freely (see Fig. K5). Remove the filler cap and drain plug (A) and drain the oil into a suitable container. Replace the drain plug and fill the gearbox through the filler cap orifice (C). Allow time for oil to pass through the inner cover into the shell. When the level plug is removed and oil runs from the level plug hole (B). Allow the surplus oil to drain off and replace the level plug and filler cap. If this method is not followed a false level indication will be gained.

### SECTION K8

### PRIMARY CHAINCASE LEVEL

An oil level plug is fitted in the primary chaincase outer cover. (See Fig. K6). To check level, remove plug (see Fig. K6, item B) whereupon oil should seep gently out if correct. If topping up is necessary, remove the filler cap (see Fig. K6, item C) and replenish with correct grade of oil until the oil begins to seep from the level plug orifice. Replace the filler cap and the level plug.
Note: under no circumstances allow more than 7fl. oz. (200 cc) of oil in primary case.
