2.4 Cylinder Liner Flange Protrusion - Measure (When Cylinder Liner Installed)
(1) Remove dust and dirt from the crankcase top face and
the cylinder liner top end face to measure.
(2) Place the liner pusher on equally spaced 4 positions of
the cylinder liner upper rim and tighten the pusher bolts
evenly to make a close contact of the cylinder liner and
the crankcase.
(3) Apply a dial gauge probe to the top face of the crank-
case, and the dial gauge to zero.
(4) Slide the probe to measure the flange protrusion at four
places on the top of the cylinder liner, and calculate the
mean value.
(5) If the mean value of the protrusion is smaller than the
standard, insert a shim under the cylinder liner flange.
For shim and standard value, refer to "Cylinder Liner
Flange Protrusion - Calculate (When Cylinder Liner
Not Installed)" of "ASSEMBLY OF BASIC ENGINE."
Cylinder Liner Flange Protrusion - Measure
2.5 Cylinder Liner Inside Diameter - Measure
Measure the inside diameter of the cylinder liner at three
levels, i.e., upper (position of No.1 compression ring when
piston is at the top dead center), liner middle position, and
O-ring installed position, in both parallel and perpendicular
directions to the piston pin direction.
Replace the cylinder liner if the value exceeds the limit. If
the liner is distorted, pull-out the liner and re-install paying
attention to O-rings.
