and unscrew the
plug. Using a piece of bent wire as a dipstick, check that the oil is no more than 10 mm (0.4 in) below the plug hole.

4 If topping-up is necessary, use clean gear oil of the specified type. Do not overfill.

Frequent need for topping-up can only be due to leaks, which should be rectified.

5 When the level is correct, refit the filler/level plug and tighten it to the specified torque loading.

6 There is no requirement for periodic oil changing, and no drain plug is provided.
