Lubrication system: oil pump
Description of the lubrication system
Forced lubrication by gear pump. Built-in pressure relief by-pass valve. Mesh intake filter. Disposable filter cartridge
on intake with safety valve preventing cartridge clogging. Low oil pressure indicator on instrument panel.
Lubrication system components:
A Mesh filter
B By-pass spring
C Oil pump
D Con-rod big end bearings
E Clutch cover
F Oil delivery to heads
G Head
H Cylinder
I Piston
L Gearbox
M Starter flywheel assembly
N Crankshaft
O By-pass spring/reed
P Cartridge filter
Q Clutch plates
Lubrication system operation
The oil gear pump (C) is driven by a toothed gear pair on the crankshaft. Pump flow rate therefore depends on engine
speed (see reference values in Sect. D 5,
).
The pump incorporates a pressure-reducing valve (B) delivering any excess oil caused by excessive pressure to the
intake end.
Oil is pumped from the oil sump through a mesh filter (A) that holds back any coarse foreign matters - before oil
reaches pump.
After flowing out of the pump, the oil flows into the cooler before reaching the cartridge filter (P), which is fitted with
an inner anti-clogging valve ensuring proper oil circulation under all conditions. Please note that oil is not filtered if the
valve opens.
After the filter, the oil flows to three different lubrication ways: two ways reach pistons as well as crankshaft bearings,
whereas the third one reaches the crankshaft (N) through an oil channel in the clutch cover (E).
As it flows into the crankshaft, oil lubricates con-rod big end bearings (D) and nozzles for piston crown cooling (L).
Then the oil also reaches the inner ring of the starter gear and the starter clutch (M).
Finally, coming out on the opposite end, the oil lubricates the crankshaft bearing in the generator cover.
The oil lubricates the camshafts through the oil delivery ways (F) to the heads (G).
Once flowing off the pressurised circuit and after lubricating the above parts, the oil lubricates primary transmission,
gearbox and gearbox shaft bearings while falling back down into the engine block.
