CYLINDER BLOCK
Checks and measurements
Internal diameter of the cylinder liners is checked for
ovalization, taper and wear, using a bore dial (1) centesimal
gauge (2) previously reset to ring gauge (3), diameter 135
mm.
If a 135 mm ring gau ge is not available use a
micrometer caliper.
A = Ø 153.500 to 153.525 mm
B = Ø 152.000 to 152.025 mm
C = Ø 153.461 to 153.486 mm
D = Ø 151.890 to 151.915 mm
The diagram shown in the figure gives the ou tside diameter
of the cylinder liner and inside diameter of its seat.
The cylinder liners can, if necessary, be extracted and fitted
several times in different seats.
