4. Install the crankshaft bearing cap carefully and tighten the

bolts to the specified torque.

5. Carefully remove the crankshaft bearing cap.
6. Measure the width of the plastic gauging material at its

widest part by using a scale printed on the plastic gauging
material package.

Standard value: 0.02

− 0.04 mm (0.0008 − 0.0015 inch)

Limit: 0.1 mm (0.003 inch)

.

CYLINDER BLOCK
1. Visually check for scratches, rust, and corrosion.

Use also a flaw detecting agent for the check. If defects are
evident, correct or replace.

2. Using a straightedge and feeler gauge, check the block top

surface for war page. Make sure that the surface is free from
gasket chips and other foreign matter.

Standard value: 0.05 mm (0.0020 inch)
Limit: 0.1 mm (0.003 inch)

3. If the distortion is excessive, correct within the allowable

limit or replace.

Grinding limit: 0.2 mm (0.007 inch)
*Includes/combined with cylinder head grinding
Cylinder block height (when new):
290 mm (11.4 inches)

4. Check cylinder walls for scratches and seizure. If defects

are evident, replace or bore to oversize and replace pistons
and piston rings.

5. Using a cylinder gauge, measure the cylinder bore and

cylindrically. If worn badly, correct the cylinder to an oversize
and replace the piston and piston rings. Measure at the
points shown in the illustration.

Standard value:

Cylinder inner diameter 86.50 mm (3.41 inches)
Cylindrically 0.01 mm (0.0003 inch) or less

BORING CYLINDER
1. Oversize pistons to be used should be determined on the

basis of the largest bore cylinder.

Piston size identification

NOTE: Size mark is stamped on the piston top.

2. Measure the outside diameter (OD) of the piston to be used.

Measure it in thrust direction as shown.

3. Based on the measured piston OD, calculate the boring

finish dimension.

Boring finish dimension = Piston OD +
(clearance between piston OD and cylinder)

−

0.02 mm (0.0008 inch) (honing margin)

CAUTION

To prevent distortion that may result from temperature rise
during honing, bore cylinders, working from number 2 to
number 4 to number 1 to number 3.
4. Bore all cylinders to the calculated boring finish dimension.
5. Hone to the final finish dimension (piston OD + clearance

between piston OD and cylinder).

6. Check the clearance between the piston and cylinder.

Clearance between piston and cylinder:
0.02

− 0.04 mm (0.0008 − 0.0015 inch)

NOTE: When boring cylinders, finish all of four cylinders to
the same oversize. Do not bore only one cylinder to an over-
size.
