ENGINE 3-73
PISTON AND CYLINDER
• Apply molybdenum oil solution onto the piston pin and small
end of the conrod.
NOTE:
Install the piston with the punch mark A on the piston head fac-
ing toward the exhaust side.
P MOLYBDENUM OIL SOLUTION
• Place a clean rag over the cylinder base to prevent the piston
pin circlip from dropping into the crankcase, and then fit the
piston pin circlip with long-nose pliers.
NOTE:
End gap of the circlip should not be aligned with the cutaway in
the piston pin bore.
• Thoroughly wipe off oil from the fitting surface of the crank-
case.
• Apply SUZUKI BOND “1215” to the crankcase
B
as shown.
E 99000-31080: SUZUKI BOND “1215”
(or equivalent bond)
• Install the dowel pins and gasket
1
onto the crankcase.
• Hold each piston ring with the piston ring sections positioned
correctly and put it into the cylinder. Make sure that the piston
rings are caught by the cylinder skirt.
NOTE:
When mounting the cylinder, after attaching the camshaft drive
chain, keep the camshaft drive chain taut. The camshaft drive
chain must not be caught between the cam drive chain sprocket
and crankcase when the crankshaft is rotated.
The removed piston pin circlip must be replaced with
a new one to prevent circlip failure.
