The full flow lubrication system uses an external
gear pump which is driven by the distributor drive
shaft. The oil pump gears are housed in the timing
cover and the oil pressure relief valve and warning
light switch are fitted to the oil pump cover.
Oil is drawn from the pressed steel sump through a
strainer and into the oil pump, excess pressure
being relieved by the pressure relief valve. The oil
pressure warning light switch is screwed into the oil
pump cover and registers the oil pressure in the
main oil gallery on the outflow side of the filter.
Pressurised oil passes through an oil cooler - if fitted
to the full flow oil filter and to internal drillings in the
crankshaft where it is directed to each main bearing
and to the big end bearings via Nos. 1, 3 and 5 main
bearings. An internal drilling in the cylinder block
directs oil to the camshaft where it passes through
further internal drillings to the hydraulic tappets,
camshaft journals and rocker shaft. Lubrication to
the thrust side of the cylinders is by oil grooves
machined in each connecting rod big end joint face,
which are timed to align with holes in the big end
journals on the power and exhaust strokes.
Engine numbers with suffix B
The full flow lubrication system uses a gear type oil
pump driven from the crankshaft. The assembly is
integral with the timing cover which also carries the
full flow oil filter, oil pressure switch and pressure
relief valve.
