Turn the reamer in a
clockwise direction
only, when reaming
or withdrawing the
reamer. For best
results, use only
moderate pressure on
the reamer.
(8)
Remove the reamer and
the connecting rod
from the fixture,
blow out the chips
and measure the
inside diameter of
the bushings. The
inside diameter of
the bushings must be
1.5015 to 1.5020 inch
(3.8138 to 3.8151 cm).
This will provide a
piston pin-to-bushing
clearance of .0015 to
.0024 inch (0.0038 to
0.0061 cm) with a new
piston pin. A new
piston pin has a
diameter of 1.4996
to 1.5000 inch
(3.8090 to 3.8100
cm).
NOTE
Piston bushings are installed in piston (refer to paragraph 6-27.1).
