D. LUBRICATION SYSTEM

Lubrication System Schematic Layout :



Description :

The lubrication system layout is as shown in

the schematic above. The oil pump is mounted in-

side the crankcase. Oil is drawn up from the sump

through oil pump strainer and passes through the

pump to the oil cooler and then to the filter.

The filtered oil flows through the internal

drilled holes into the crankshaft oil gallery from here

it is supplied to connecting rod bearings and also to

the main bearings by means of intersecting passag-

es drilled in the crankshaft. It is then injected

through the cooling nozzles to the underside of the

piston / piston gallery for cooling. There is a sepa-

rate line that goes to lubricate the turbocharger and

the air compressor.

There is another path which takes the oil up

from the crankshaft oil gallery to camshafts oil gal-

lery in cylinder head and lubricates the camshaft.

The camshaft oil gallery also provides the oil need-

ed by the rocker arm. The relieved oil drains back to

oil sump.

The Lubrication System consists of the fol-

lowing components.

1. Oil Pump

2. Oil Filter.

3. Oil Strainer.

4. Oil Cooler.

5. Hydraulic Lash Adjuster (HLA)

6. Piston Cooling Nozzles.

7. Oil Pressure Switch
