Measuring Bore Wear
Tools:
1 Inside micrometer 94101
1 Ladder 94224
1 Measuring gauge 94225
Measure the cylinder liner wear before you
remove a piston.
1) Remove the cylinder cover, (see
2708−1).
2) Use the turning gear to move the piston
to BDC.
3) Clean the non-running surface 4.
4) Remove the bottom part of the gauge
(94225).
5) Put the gauge (94225) in position on
the top face of the cylinder liner 1 in
line with the longitudinal axis of the
engine.
6) Make sure that the top measurement
position A is above the ridge in the
non-running surface of the cylinder liner
1.
7) Read the values from the last bore
wear measurement. You compare
these values with the new values.
8) Put the micrometer (94101) in the top
hole A, to measure the distance.
Record the value.
9) Put the micrometer in position in the
subsequent hole B in the gauge
(94225), then record the value.
10) Do the step above for the remaining
holes below A and B.
11) Move the gauge 90_ (in line with the
transverse axis of the engine).
12) Do the steps above again to measure
the bore wear in the positions F up to
A.
