REMOVING THE PISTONS
The following procedure applies to all of the pis-
ton.
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 clip, cover the
crankcase opening with a clean rag to prevent
the piston pin clip from falling into the crank-
case.
• For reference during installation, put an identi-
fication mark on each piston crown.
• Before removing the piston pin, deburr the pis-
ton pin clip’s groove and the piston’s pin bore
area. 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.
