PISTON INSPECTION

E5U011011010E01

Caution

• The piston and connecting rod cannot be disassembled.

• When replacing the piston, piston pin, piston ring and connecting rod, replace them together as a

single unit.

1. Measure the outer diameter of each piston at right

angle 90° to the piston pin, 10.0 mm {0.40 in}

above the under of the piston.

• If not within the specification, replace the

piston, piston pin, piston ring and connecting

rod as a single unit.

Piston diameter (Standard)

87.465—87.495 mm {3.4435—3.4446 in}

2. Measure the piston-to-cylinder clearance.

• If not within the specification, replace the

piston, piston pin, piston ring and connecting

rod as a single unit.

Piston-to-cylinder clearance (Standard)

0.025—0.045 mm {0.0010—0.0017 in}

Piston-to-cylinder clearance (Maximum)

0.11 mm {0.0043 in}

3. Measure the piston ring-to-ring groove clearance around the entire circumference.

• If it exceeds the specification, replace the piston, piston pin, piston ring and connecting rod as a single unit.

Piston ring-to-ring groove clearance

(Standard)

Top: 0.03—0.08 mm {0.0012—0.0031 in}

Second: 0.03—0.07 mm {0.0012—0.0027 in}

Oil: 0.03—0.07 mm {0.0012—0.0027 in}

Piston ring-to-ring groove clearance

(Maximum)

Top: 0.17 mm {0.0067 in}

Second, Oil: 0.15 mm {0.0059 in}
