CRANKSHAFT OIL CLEARANCE (PLASTIGAGE
METHOD)
The crankshaft oil clearance can be measured easily by using
a plastigage, as follows:
1. Remove oil and grease and any other foreign matters from
crankshaft journal and bearing inner surface.
2. Install the crankshaft.
3. Cut the plastigage to the same length as the width of
bearing and place it on journal in parallel with its axis.
4. Gently place the crankshaft bearing cap over it and tighten
the bolts to the specified torque.
5. Remove the bolts and gently remove the crankshaft bearing
cap.
6. Measure the width of the smashed plastigage at its widest
section by using a scale printed on the plastigage bag.
Standard value:
Number 1 and 4 journal
0.018
− 0.038 mm (0.0008 − 0.0014 inch)
Number 2 and 3 journal
0.024
− 0.044 mm (0.0010 − 0.0017 inch)
Limit: 0.1 mm (0.004 inch)

1. Using a straightedge and thickness gauge, check the block
top surface for warpage. Make sure that the surface is free
from gasket chips and other objects.
Standard value: 0.05 mm (0.002 inch)
Limit: 0.1 mm (0.004 inch)
2. If the distortion is excessive, replace the cylinder block.
3. Check cylinder walls for scratches and seizure. If defects
are evident, correct (bored to oversize) or replace.
4. Using a cylinder gauge, measure the cylinder bore, and
cylindricity. If worn badly, correct cylinder to an oversize and
replace piston and piston rings. Measurement points are
shown in illustration.
Standard value
Cylinder I.D.: 87.6 mm (3.45 inch)
Cylindricity: 0.015 mm (0.0006 inch)
