PISTON
• Install the piston rings in the order of oil ring, 2nd ring and 1st
ring.
• The first member to go into the oil ring groove is a spacer 1.
After placing the spacer, fit the two side rails 2.
NOTE:
Side designations, top and bottom, are not applied to the spacer
and side rails: you can position each either way.
When installing the spacer, be careful not to allow its
two ends to overlap in the groove.
• Install the 2nd ring and the 1st ring.
NOTE:
1st ring and 2nd ring differ in shape.
• 1st ring and 2nd ring have letters "N" and "2N" marked on the
side. Be sure to bring the marked side to the top when fitting
them to the piston.
• Position the gaps of the three rings as shown. Before inserting
each piston into the cylinder, check that the gaps are so lo-
cated.

PISTON AND CONROD
• When installing the pistons, the indent on the piston head must
be faced to exhaust side.
• Rub a small quantity of molybdenum oil solution onto each pis-
ton pin.
MOLYBDENUM OIL
• Install the pistons.
NOTE:
Be sure to install the pistons in the cylinders from which they
were removed in disassembly, refer to the cylinder numbers, "1"
through "4", scribed on the piston.
• Install the piston pin circlips.
Use new piston pin circlips to prevent circlip failure which
will occur with a bend one.
NOTE:
End gap of the circlip should not be aligned with the cutaway in
the piston pin bore.
