Installation
1. Select the cylinder head gasket.
Cylinder Head Gasket Selection
Cylinder head gasket is determined by the piston head
projection from the cylinder body upper surface, in orde
r
to improve engine performance.
Three types of gasket are provided with difference o
f
thickness. Select the appropriate one out of three
grades of
gasket, according to the following procedure.
Before measurement, clear off carbon from the piston
head and cylinder body surface and also clean the
place where the gasket was installed.




011LX011
1. Use a dial indicator to measure the piston
projection amount.
2. Refer to the illustration for the piston head projection measuring positions. All measuring
positions should be as close as possible to the
cylinder block.








RTW 36ASH001701
3. Measure the points 1, 2, 3, 4 and obtain two
differences 1-2 and 3-4 on each cylinder. Calculate
the average value of the piston head projection on
each cylinder.
4. Obtain the maximum value in the four cylinders.
5. Determine the gasket grade required to the maximum value described above in accordance
with the following table.

Inspection
1. Thrust clearance
• Measure the crankshaft end play at the cente
r
journal of the crankshaft.
• Do this before removing the crankshaft bearing
caps. If the measured value exceeds the
specified limit, the crankshaft thrust bearing
must be replaced.
Axial play of the crankshaft mm (in)
Standard 0.10 (0.004)
Limit 0.30 (0.012)
Note:
Measure the thrust clearance before dismounting.

2. Main bearing clearance
• Remove the crank case.
Set out disassembled main bearings in the order of the numbers.
• Remove the crankshaft. Remove the main
bearings.
• Clean the crankshaft journal and upper and
lower bearings.
• Check the bearings for damage or excessive
wear.

If you find damage or excessive wear, replace the bearings in pairs.

• Place the upper bearings and the crankshaft on
the cylinder block. Install the crankshaft so that
it is horizontal.
Note:
Turn the crankshaft about 30 degrees to allow the
bearings to settle in.
• Place plastigage on the crankshaft journal as
shown.
• Place the lower bearings at original positions on
the bearing cap.
