PISTON AND CONNECTING ROD INSPECTION

.

PISTON RING INSPECTION

1. Check the piston ring for damage, excessive wear, and 

breakage. Replace if defects are evident. If the piston has 
been replaced with a new one, the piston rings must also be 
replaced with new ones.

2. Check for clearance between the piston ring and ring 

groove. If the limit is exceeded, replace the ring or piston, or 
both.

Standard value:

Number 1: 0.04 

− 0.08 mm (0.0016 − 0.0031 inch)

Number 2: 0.03 

− 0.07 mm (0.0012 − 0.0027 inch)

Limit: 0.1 mm (0.004 inch)

3. Insert the piston ring into the cylinder bore. Force the ring 

down with a piston, the piston crown being in contact with 
the ring, to correctly position it at right angles to the cylinder 
wall. Then, measure the end gap with a feeler gauge.
If the ring gap is excessive, replace the piston ring.

Standard value:

Number 1: 0.18 

− 0.33 mm (0.008 − 0.012 inch)

Number 2: 0.28 

− 0.48 mm (0.012 − 0.018 inch)

Oil: 0.10 

− 0.60 mm (0.004 − 0.023 inch)

Limit:

Number 1, Number 2: 0.8 mm (0.03 inch)
Oil: 1.0 mm (0.04 inch)

.

CRANKSHAFT PIN OIL CLEARANCE 
<PLASTIGAGE METHOD>

The crankshaft oil clearance can be measured easily by using 
plastigage method, as follows:
1. Remove oil from the crankshaft pin and the bearing inner 

surface.

2. Cut plastigage to the same length as the width of the 

bearing and place it on the pin in parallel with its axis.

3. Install the connecting rod cap carefully and tighten the nuts 

to the specified torque.

4. Carefully remove the connecting rod cap.

5. Measure the width of the smashed plastigage at its widest 

section by using a scale printed on the plastigage bag.

Standard value: 0.012 

− 0.039 mm (0.0005 − 0.0015 

inch)
Limit: 0.1 mm (0.004 inch)
