REMOVING THE PISTON

1. Remove:

• Piston pin clips “1”
• Piston pin “2”
• Piston “3”

NOTICE

ECA13810

Do not use a hammer to drive the piston pin 
out.

TIP

• Before removing the piston pin clips, cover the 

crankcase opening with a clean rag to prevent 
the piston pin clips from falling into the crank-
case.

• Before removing the piston pin, deburr the pis-

ton pin clip grooves and the piston pin bore ar-
ea. If both areas are deburred and the piston 
pin is still difficult to remove, remove it with the 
piston pin puller set “4”.

2. Remove:

• Top ring
• 2nd ring
• Oil  ring

TIP

When removing a piston ring, open the end gap 
with your fingers and lift the other side of the ring 
over the piston crown.
