DESCRIPTION AND OPERATION

1. Oil squirt jets (5 off)
2. Main oil delivery gallery
3. Inflow from oil cooler housing
4. Flow to oil cooler / filters (from oil pump via cylinder block)
5. Sump
6. Oil pick-up pipe
7. Flow from oil pump (relief-valve in housing)
8. Oil pump
9. Cross-drilling supply to main and crankshaft bearings

10. To cylinder head

Oil from the sump is drawn up through a two-piece plastic pick-up which contains a mesh to siphon any relatively
large pieces of material which could cause damage to the pump. The head of the pick-up is centrally immersed in
the sump oil and oil is delivered to the inlet side of the eccentric rotor pump through a gallery in the stiffener plate.

Pressurised oil from the pump is passed through to the cylinder block where it is delivered to the centrifuge filter
and full-flow filter via a port in the RH cylinder block which interfaces with a port in the centre gallery of the oil
cooler housing. The oil pump contains an oil pressure relief valve which opens to allow oil to be recirculated back
around the pump if the oil pressure increases to a high enough level.

10% of the oil flow from the pump is diverted through the centrifuge filter and returned to the sump via the
centrifuge filter drain tube. The remaining 90% of the oil passes through the standard full-flow filter to the main oil
gallery in the cylinder block.
