7) Put the gauge (94225, Fig. 1) in position on the top face of the cylinder liner (3) in
line with the longitudinal axis of the engine.
8) Make sure that the top hole (A) is above the ridge in the non-running surface of
the cylinder liner (3).
9) Read the values from when the bore was measured before. You compare these
values with the new values.
10) Put the micrometer (94101) in the top hole (A) to measure the distance. Record
the value.
11) Put the micrometer (94101) in position in the subsequent hole (B) in the gauge
(94225), then record the value.
12) Do step 11) above for the remaining holes below (A and B).
13) Move the gauge 90_ (in line with the transverse axis of the engine).
14) Do the steps above again to measure the bore in the positions (F up to A).
15) Use the formula below to calculate the rate of wear:
WR = (D1−D2) x 1000
T1
Where:
WR = Rate of Wear (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)
16) For the maximum permitted inner diameter, refer to 0330−1 Clearance Table,
Cylinder liner.
17) Remove all unwanted particles from the cylinder liner bore.
18) Clean the cylinder liner bore.
Note: To remove the ridge of material at the top of the cylinder bore, refer to
(see 2124−3).
