Operation
Refer to Camshaft-Operation PIL 15-15-00 .
Lubrication
Oil is fed from the main gallery via five drillings, one
to each of the main bearings. A groove around the
diameter of the upper main bearing shell allows oil
transfer to cross drillings in the crankshaft to feed
each of the big end bearings. Crankshaft gear is
'splash' lubricated. Front and rear crankshaft oil seals
prevent oil leakage from, and dirt ingress to, the
engine.

Introduction
In a piston engine, the main bearings are the
bearings on which the crankshaft rotates.
The bearings hold the crankshaft in place and
prevent the forces created by the piston and
transmitted to the crankshaft by the connecting rods
from dislodging the crankshaft, instead forcing the
crank to convert the reciprocating movement into
rotation.

Operation
As the crankshaft rotates the camshaft also rotates,
driven by a gear on the crankshaft. The inlet and
exhaust valves are opened by lobes on the camshaft
in time with the cycle.
The diagrams show the position of the camshaft at
each part of the four stroke cycle, refer to Engine-
General, Operation. Refer to: PIL 15-00-00.
It can be seen that for a complete cycle the camshaft
revolves once. Since the crankshaft revolves twice
during the cycle it follows that the camshaft is driven
at half crankshaft (engine) speed.
Lubrication
Oil is fed from the main gallery via a drilling to the
camshaft bearing. A groove around the diameter of
the bearing and connecting the cross drilling ensures
that oil is always fed to the centre drilling. Oil is then
transferred to the remaining camshaft bearings by
further cross drillings in the shaft. The cam lobes and
tappets are 'splash' lubricated.

scoring. Check that the dimensions are within
service limits.
5. Inspect the bearing surfaces of the tappets for
signs of excessive wear or damage. Check that
the dimensions are within service limits.
6. Inspect the tappet bores inside the crankcase for
signs of excessive wear or damage. Check that
the dimensions are within service limits.
7. If any of the camshaft bearings or lobes are worn
or damaged then the relative oil feed galleries
in the crankcase and camshaft may be blocked.
Make sure all oil ways are clear and free from
debris.
