1D-73 Engine Mechanical:

Rear Oil Seal and Flywheel Inspection

S6JB0B1406047

Rear Oil Seal
Carefully inspect oil seal for wear or damage. If lip
portion is worn or damaged, replace oil seal.

Flywheel
• If ring gear is damaged, cracked or worn, replace

flywheel.

• If the surface contacting clutch disc is damaged or

excessively worn, replace flywheel.

• Check flywheel for face runout with a dial gauge. If

runout exceeds its limit, replace flywheel.

Flywheel runout
Limit: 0.2 mm (0.0078 in.)

Cylinder Block Inspection

S6JB0B1406048

Distortion of Gasketed Surface
Using straightedge and thickness gauge, check
gasketed surface for distortion. If flatness exceeds its
limit, correct or replace it.

Gasketed surface flatness
Limit: 0.06 mm (0.0024 in.)

Honing or reboring cylinders

1) When any cylinder needs reboring, all other

cylinders must also be rebored at the same time.

2) Select oversized piston according to amount of

cylinder wear.

Oversize piston diameter
88.470 – 88.490 mm (3.4831 – 3.4838 in.)

3) Using micrometer, measure piston diameter.

4) Calculate cylinder bore diameter to be rebored as

follows.
D = A + B – C
D: Cylinder bore diameter to be rebored
A: Piston diameter as measured
B: Piston clearance = 0.02 – 0.04 mm (0.0008 –
0.0015 in.)
C: Allowance for honing = 0.02 mm (0.0008 in.)

5) Rebore and hone cylinder to calculated dimension.

NOTE
Before reboring, install lower crankcase in
place and tighten to specification to avoid
distortion of bearing bores.

6) Measure piston clearance after honing.
