Lubrication

Lubrication
Lubrication is by splash, oil filler/level and drain plugs being located in the main casing.

Internal pressures caused by thermal expansion and contraction are avoided by the use of a plastic breather pipe venting the interior of the box to atmosphere. The pipe is attached to the top of the high/low selector housing by a banjo bolt and is then routed in a continuously rising path into the engine compartment where the open end is secured by a clip attached to the engine cylinder block.
