Assembling Piston, Piston Rings
and Con Rod
1 Install one of the retainer rings in the piston.
2
Oil the piston pin and connecting rod bush.
3 Heat the piston to approx. 100°C (212 °F). Posi-
tion the piston and connecting rod so that the
markings line up.
The marking on the connecting rod and the "SHI-
BAURA" marking inside the piston must face the
same direction.
Slide the piston pin in.
NOTICE! It should be possible to press the piston
pin in easily. It must not be driven in.
4
Install the other retainer ring.
5 Check that the connecting rod is not tight on the
piston pin bearing.
6 Check the big end bearing clearances. Refer to
Crankshaft and Bearings, Inspection page 90.
7 Check the piston ring gap in the cylinder bore and
that the rings do not bind in the piston ring
grooves.
