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 and is routed in a continuously rising path into the engine compartment where the open end is secured to the engine cylinder block.
