29. Install the cover (G) and nut (H) (putting the threaded part (I) of

the nut on the side away from the engine) of front oil seal drift
set [SST: KV113B0210 (Mot. 1585)].

30. Tighten the nut until the cover touches the cylinder block.

31. Remove the nut, the cover, the protector and the threaded rod.

32. Install ring gear stopper [SST: KV113B0060 (Mot. 582-01)] and

tighten flywheel bolts with new one.

33. Turn all bolts 36 degrees clockwise (angle tightening).

CAUTION:

Check and confirm the tightening angle by using the angle
wrench [SST: KV10112100 ( — )] or protractor. Avoid judg-
ment by visual inspection without the tool.

34. Install the clutch housing.

35. Remove ring gear stopper [SST: KV113B0060 (Mot. 582-01)].

CYLINDER BLOCK TOP SURFACE DISTORTION

• Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or

other contamination. 

CAUTION:

Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.

• Measure the distortion on the cylinder block upper face at some

different points in six directions with a straight edge (A) and feeler
gauge (B).

• If it exceeds the limit, replace cylinder block.

PISTON PROTRUSION

1.

Clean the piston head.

2.

Turn the crankshaft one turn in its operating direction to bring piston No. 1 close to TDC.

3.

Install dial gauge stand set [KV113B0050 (Mot. 252-01) (com-
mercial service tool) or equivalent tool] on the piston.

4.

Install dial gauge stand set [KV113B0040 (Mot. 251-01) (com-
mercial service tool) or equivalent tool] equipped with a gauge
on dial gauge stand set [KV113B0050 (Mot. 252-01) (commer-
cial service tool) or equivalent tool], and find TDC.
NOTE:
All measurements must be carried out along the longitudinal
axis of the engine, in order to eliminate any errors due to tilting
of the piston.

WARNING:

The gauge follower must not be in the valve clearance. 

5.

Inspect the piston protrusion. 

CRANKSHAFT LATERAL PLAY

1.

Install crankshaft.

2.

Install piston and connecting rod assembly.

3.

Inspect that the big end lateral play.

PISTON DIAMETER

Measure the piston diameter.
The piston diameter (A) must be measured at height (a) = 56 mm
(2.205 in).

PISTON RING THICKNESS

Measure piston ring thickness with micrometer.

• The piston rings are supplied ready adjusted.

PISTON RING SIDE CLEARANCE

• Measure the side clearance of piston ring and piston ring groove

with a feeler gauge (A).

• If the measured value exceeds the limit, replace piston ring, and

measure again. If it still exceeds the limit, replace piston also.

PISTON RING END GAP

• Lubricate with new engine oil to piston (1) and piston ring (2), and

then insert (A) piston ring until middle of cylinder (B) with piston,
and measure piston ring end gap with a feeler gauge (C).

• If the measured value exceeds the limit, replace piston ring.

CHECKING THE DIAMETER, OUT-OF-ROUNDNESS AND TAPER OF BARRELS

Using a Dial gauge, measurethe diameter (D1) of the cylinder block barrelsat in intervals of 45

°

 (4 diagonals)

at 3 levels (N1), (N2) and (N3): 
• 10 mm,
• 64 mm,
• 117 mm,
depth from the cylinder head joint face and note these 12 diameter values for each cylinder.

Check that these 48 diameter measurements are all within the barrel diameter tolerance.

Check that the difference between the largest and the smallest diameters at each depth level in each cylinder
is within the out-of-roundnes tolerance.
