Replacement of Piston Ring

• Measure piston ring end play.

- Piston ring end play (mm)

1st groove: 0.20 ~ 0.35

2nd groove: 0.20 ~ 0.35

3rd groove: 0.20 ~ 0.40

- Clearance between piston ring and piston (mm)

1st compression ring: 0.075 ~ 0.119

2nd compression ring: 0.050 ~ 0.090

3rd oil ring: 0.030 ~ 0.070

• Install the piston so that “Y” marking on piston head is

facing in the direction of travel. Arrange the piston ring
ends to be 120° apart.

• Adjust the hook spring joint in the oil ring 180 ° away from

the ring end.

DISASSEMBLY AND REASSEMBLY

1. Install the compression ring and oil ring on the piston

with a special tool.

2. Check the clearance of piston oil ring and compression

ring with a thickness gauge and adjust if necessary.

3. Check the clearance of piston rings with a thickness

gauge and adjust if necessary.

Notice

• Install the No.1 and No.2 pistons so that “Y” marking

on piston head is facing upward.

• No.1 piston ring is thicker than No.2 piston ring.

• Arrange the oil ring end to opposite position of

current ring end.

• Oil ring is not directional.

• Make sure that the piston ring end is not aligned to

axial direction and lateral direction.
