Piston skirt diameter
See CYLINDER section for cylinder bore measu- rement
If not as specified, replace the piston and piston rings as a set
Piston-to-cylinder clearance: 0.025 ~ 0.035 mm
3. Measure:
• Piston bore diameter
If not as specified, replace
Piston bore diameter: 15.002 ~ 15.013 mm | |||

If it is grooved or has a blue discoloration, repla- ce or clean
CHECKING PISTON RINGS
1. Measure:
• Side clearance
If not as specified, replace the piston and the piston rings as a set
NOTE:
Clean away carbon deposits from the piston ring grooves and rings before measuring the side clearance Ø
Side clearance (piston ring): Top ring: | |
0.03 ~ 0.07 mm <Limit: 0.12 mm> 2nd ring: 0.02 ~ 0.06 mm <Limit: 0.12 mm> |
2. Position:
• Piston ring Ø
(into the cylinder)
NOTE:
Push the ring with the piston crown so that the ring is at a right angle to the cylinder bore

INSTALLING PISTON RINGS, PISTON AND CYLINDER
1. Install:
• Expander spacer (oil ring)
• Side rails (oil ring) Ø
• 2nd ring Ø
• Compression ring Ø
NOTE:
Make sure to install the piston rings so that the manu- facturer’s marks or numbers are located on the upper side of the rings
Lubricate pistons and piston rings liberally with engi- ne oil
2. Install:
• Piston Ø
• Piston clip Ø
• Piston pin clip Ø
NOTE:
Apply engine oil to the piston pins
The “—( “ mark §a on the piston must face the
exhaust side of the cylinder
Before installing the piston pin clip, cover the crank- case opening with a clean rag to prevent the piston clip from falling into the crankcase
Make sure to install each piston in its respective cylin- der
