directed to the 12 o'clock position, install the ther-
mostat and housing; then in a crisscross pattern,
tighten the screws to 102 in.-lb.
19. Install the dowel pins into the crankcase; then place
the cylinder base gasket into position on the crank-
case.

KDN5 on the top (inclined surface) of each ring
faces the dome of the piston.

Incorrect installation of the piston rings will result in
engine damage.
21. Apply oil to the connecting-rod small end bearings;
then install the small-end bearings.
22. Place each piston over the connecting rod so the indi-
cator arrow on each piston will point toward the
exhaust ports; then secure with an oiled piston pin.
 NOTE: The indicator arrow is found on the piston
dome.
23. Install the new circlips so the open end is directed
either up or down.
Make sure the circlips are firmly seated before continu-

25. 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 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 pistons into the cylinders.
