6. Put a paint mark on the bolt head as illustrated.

7. Put a paint mark on the connecting rod at 90

° 

position in the tightening direction of the bolt with 
reference to the paint mark position of the bolt.

CAUTION

• When the tightening angle is smaller than the 

specified tightening angle, the appropriate 
tightening capacity cannot be secured.

• When the tightening angle is larger than the 

specified tightening angle, remove the bolt to 
start from the beginning again according to 
the procedure.

8. Tighten the bolt 90

°, and make sure that the paint 

mark of the connecting rod is aligned with that of 
the bolt.

PISTON RINGS

AK502751

1. Check clearance between piston rings and ring 

grooves. If the limit is exceeded, replace piston 
rings or piston, or both.

Standard value:

No. 1 ring: 0.03 

− 0.07 mm

No. 2 ring: 0.03 

− 0.07 mm

Limit: 0.1 mm

2. Put piston rings into the cylinder bore, press them 

against the piston top face, and push them in. 
After achieving squareness, measure the end gap 
with a thickness gauge. If the end gap is 
excessive, replace piston rings.

Standard value:

No. 1 ring: 0.15 

− 0.28 mm <4B11>

No. 1 ring: 0.15 

− 0.25 mm <4B12>

No. 2 ring: 0.30 

− 0.45 mm <4B11>

No. 2 ring: 0.25 

− 0.40 mm <4B12>

Oil ring: 0.10 

− 0.35 mm

Limit:

No. 1 ring: 0.8 mm
No. 2 ring: 0.8 mm
Oil ring: 1.0 mm

CRANKSHAFT PIN OIL CLEARANCE 
(PLASTIGAGE METHOD)

1. Wipe oil off the crankshaft pin and connecting rod 

bearing.

2. Place a Plastigage in length equal to the bearing 

width on the pin shaft straight in alignment with 
the shaft centre.

REMOVAL SERVICE POINT

<<A>> CRANKSHAFT REMOVAL

When temporarily placing the crankshaft with the 
crankshaft sensing ring attached, temporarily place it 
on a V-block to prevent teeth of the sensing ring from 
deforming.

NOTE: If a tooth bends, be sure to replace the crank-
shaft sensing ring with a new one.
