INSTALLING THE PISTONS AND CYLIN-
DERS
The following procedure applies to all of the pis-
tons and cylinders.
1. Install:
top ring 1
2nd ring 2
lower oil ring rail
3
upper oil ring rail 4
oil ring expander 5
Be sure to install the piston rings so that the
manufacturer’s marks or numbers
a
are lo-
cated on the upper side of the rings.
The piston rings that have an “R” mark must be
installed into the 2nd ring groove.
2. Install:
piston 1
piston pin 2
piston pin clip (New) 3
Apply engine oil onto the piston pin.
Make sure that the arrow mark
a
on the piston
points towards the exhaust side of the engine.
Before installing the piston pin clip, cover the
crankcase opening with a clean rag to prevent
the piston pin clip from falling into the crank-
case.
Reinstall each piston into its original cylinder
(numbering order starting from the left: #1 to
#4).
