2. Measuring method 2
⇒ Displace the crankshaft axially until it rests on the engine side thrust bearing
pads 6a (AHEAD) and then fix it in this position (Fig. ’A’).
⇒ Measure the distance between the coupling flange and upper part 2 of the oil
baffle with inside micrometer 94101 at the position indicated (see Fig. ’B’).
The amount by which distance ’X’ is smaller than that given on the page
’Check Dimensions’ corresponds to the wear of the engine side thrust bearing
pads (AHEAD).
⇒ Displace the crankshaft axially until it rests on thrust bearing pads 6
(ASTERN). Determine the total axial clearance with the inside micrometer.
