• The numbers stamped into the crankshaft web
and the numbers on the connecting rods are

and the
crankshaft web P

INSTALLING THE CONNECTING RODS AND
PISTONS
The following procedure applies to all of the pis-
tons and connecting rods.
1. Install:
• Top ring “1”
• 2nd ring “2”
• Upper oil ring rail “3”
• Oil ring expander “4”
• Lower oil ring rail “5”
NOTE:
Be sure to install the piston rings so that the
manufacturer’s marks or numbers “a” face up.
2. Install:
• Piston “1”
(onto the respective connecting rod “2”)
• Piston pin “3”
• Piston pin clips “4”
NOTE:
• Apply engine oil onto the piston pin.
• Make sure that the “Y” mark “a” on the connect-
ing rod left when the punch mark “b” on the pis-
ton is pointing up. Refer to the illustration.
• Install the piston pin clips, so that the clip ends
are 3 mm (0.12 in) “c” or more from the cutout
in the piston.
• Reinstall each piston into its original cylinder
(numbering order starting from the left: #1 to
#4).
