24. Install the dowel pins into the crankcase; then
place the cylinder base gasket into position on the
crankcase.
25. Install the piston rings on each piston so the letter
on the top (inclined surface) of each ring faces the
dome of the piston.
726-306A
26. Apply oil to the connecting-rod small end bear-
ings; then install the small-end bearings. Install a
washer on each side of the connecting rod.

NOTE: The shoulder side of the washer must
seat to the needle bearing.

27. Place each piston over the connecting rod so the
indicator dot on each piston will point toward the
intake/exhaust ports; then secure with an oiled pis-
ton pin.
NOTE: The indicator dot is found on the piston
dome top.

28. Install the new circlips so the open end is directed
either up or down.
CM195B
NOTE: To aid in the circlip installation, install the
circlip to the inside of the piston before installing
the connecting rod.
29. Rotate each piston ring until the ring ends are
properly positioned on either side of the ring
keeper; then apply oil to the piston assemblies and
cylinder bores. Remove the rubber bands or hoses
from the connecting rods.
30. In turn on each cylinder, place a piston holder (or
suitable substitute) beneath the piston skirt and
square the piston in respect to the crankcase; then
using a ring compressor or the fingers, compress
the rings and slide the cylinder over the piston.
Remove the piston holder and seat the cylinder
firmly onto the crankcase.
NOTE: The cylinders should slide on easily. DO
NOT force the cylinders on.
CAUTION
Incorrect installation of the piston rings will result in
engine damage.
CAUTION
Make sure the circlips are firmly seated and the open
end is directed either up or down before continuing
with assembly.
