4.Carefully place the main bearing caps, and tighten the bolts to the specified torque.
5.Remove the bolts. Carefully remove the main bearing caps.
CRANKSHAFT OIL CLEARANCE (USING PLASTIGAGE) |
| Oil clearance can be measured
easily by using "plastigage." |
| Use the "plastigage" in the
following manner. |
| 1.Wipe off oil from the
surfaces of the crankshaft journals as well as the inner
surfaces
of the bearings. |
| 2.Assemble the
crankshaft. |
|
3.Place a plastigage, with a
length equal to the width of the bearing, onto the journals
in the axial direction. 4.Carefully place the main bearing caps, and tighten the bolts to the specified torque. 5.Remove the bolts. Carefully remove the main bearing caps. |
 |
6.Using the measure printed
on the plastigage package, measure the width (widest
portion)
of the crushed plastigage. Standard value: 0.023 - 0.043 mm Limit: 0.1 mm |
CYLINDER BLOCK |
| 1.Check visually for
scoring, rust, or corrosion. Perform liquid penetrant test
etc.
to check for cracks. If faulty, replace. |
 |
2.Using a straight edge or a
thickness gauge, measure the flatness of the cylinder block
top surface. Ensure that no gasket or other foreign matter
is attached to the top face. Standard value: 0.05 mm Limit: 0.1 mm 3.Check the cylinder bore for scoring or seizure. If faulty, replace. |
 |
4.Using a cylinder gauge,
measure the cylinder bore and centricity. If excessively
worn,
replace the cylinder block. Standard value:
Cylindrically 0.01 or less mm |
