Measure the outer diameter of piston pin with a micrometer (A).

Piston to Piston Pin Oil Clearance

(Piston to piston pin oil clearance) = (Piston pin hole diameter) – (Piston pin outer diameter)

• If oil clearance is out of the standard, replace piston and piston pin assembly. 

• When replacing piston and piston pin assembly. Refer to 

EM-133, "Description"

.

NOTE:

• Piston is available together with piston pin as assembly.

• Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no

grades can be selected. (Only grade “0” is available.) 

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

• Check that cylinder bore inner diameter is within specification. Refer to “PISTON TO CYLINDER BORE

CLEARANCE”.

• 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, and

measure again. If it still exceeds the limit, rebore cylinder and use

oversized piston and piston rings.

1. Install clutch cover mounting bolt (1) to clutch cover mounting

hole, and place a torque wrench (A) on the extended line of the

flywheel (2) center line.

• Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it
