7) Put the micrometer (94226) in the top hole (A) in the gauge (94225) to measure the
distance. Record the value.
8) Put the micrometer (94226) in the subsequent hole (B) in the gauge (94225) to
measure the distance. Record the value.
9) Do the step above for the remaining holes below (A) and (B).
10) Move the gauge 90
_
(in line with the transverse axis of the engine).
11) Do the steps above again to measure the bore in the positions (F) up to (A).
12) Use the formula below to calculate the rate:
WR = (D1 − D2) x 1000
T1
Where:
WR = Wear rate (mm/1000 hours)
T1 = Total running hours (h)
D1 = Maximum liner diameter of running surface (point B and below) (mm)
D2 = Liner diameter of non-running surface (point A) (mm)
13) For the maximum permitted inner diameter, refer to 0330 − 1 Clearance Table,
Cylinder liner.
14) Remove all waste particles from the cylinder liner bore.
15) Clean the bore of the cylinder liner.
