Introduction
The cylinder head is located above the cylinders
on top of the crankcase. It closes in the top of the
cylinder, forming the combustion chamber. This joint
is sealed by a cylinder head gasket.
The cylinder head also provides the space for the
passages that feed air and fuel to the cylinder and
allow the exhaust to escape. The cylinder head is
also used to mount the valves (PIL 15-30) and fuel
injectors (PIL 18-18).

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.

13. 15 - Engine

03 - Main Bearing
15 - 40 9813/6200-1 15 - 40
Check (Condition)
Check the condition of the main bearings by
measuring the clearance between the two bearing
halves.
If the crankshaft journals and the bores for the
crankcase and connecting rods were measured,
no further checks are necessary. If the bearing
clearance measurement is necessary, the use of
the plastic gauge is an acceptable method. The
plastic gauge is less accurate on journals with small
diameters if the clearances are less than 0.1mm.
When you use the plastic gauge make a note of the
following:
• Make sure that the backs of the bearings and
the bores are clean and dry.
• Make sure that the bearing locking tabs are
properly seated in the tab grooves.
• The crankshaft must be free of oil at the contact
points of the plastic gauge.

Green 0.025–0.076mm
Red 0.051–0.152mm
Blue 0.102–0.229mm
Yellow 0.23–0.51mm
Measurement Procedure
1. Put the plastic gauge on the crown of the bearing
that is in the cap.
2. Do not allow the plastic gauge to extend over the
edge of the bearing.
3. Use the correct torque-turn specifications in
order to install the bearing cap.
4. Do not use an impact wrench. Be careful not to
dislodge the bearing when the cap is installed.
5. Do not turn the crankshaft when the plastic gauge
is installed.
6. Carefully remove the cap, but do not remove the
plastic gauge.
