3. With the cylinder
liner installed in
the cylinder block,
hold the piston up-
side down in the
liner and check the
clearance in four
places 90apart.
4. Use feeler gage set
to check the clear-
ance. The spring
scale, attached to
the proper feeler
gage, is used to
measure the force in
pounds required to
withdraw the feeler
gage.
5. Select a feeler gage
with a thickness
that will require a
pull of six pounds
(26.7 N) to remove.
The clearance will
be .001 inch (0.003
cm) greater than the
thickness of the gage
used, i.e., a .004
inch (0.010 cm) feeler
gage will indicate a
clearance of .005
inch (0.013 cm) when
it is withdrawn with
a pull of six pounds
(26.7 N). The feeler
gage must be perfectly
flat and free of nicks
and bends.
