Tools: Key to Illustrations:
1 Inside micrometer 94101 1 Coupling flange 7 Thrust bearing pads
1 Feeler gauge 94238 2 Oil baffle, upper part for ASTERN
1 Dial gauge with magnetic base 3 Oil baffle, lower part 7a Thrust bearing pads
4, 4a Holder for AHEAD
5 Thrust flange 8 Cover
6 Crankshaft
1. Measuring method 1
The total displacement which results from pushing the crankshaft axially both
ways until it contacts the thrust bearing pads AHEAD and ASTERN, is measured
with a dial gauge. This is then checked against the figure marked on the sheet
’Check Dimensions’ in the engine documents supplied (see also Clearance Table
0330 − 1 ’Crankshaft and main bearing’).
An increase compared with the nominal figure signifies wear of the thrust bearing
pads.
2. Measuring method 2
⇒
Displace the crankshaft axially until it rests on the engine side thrust bearing
pads (AHEAD) and then fix it in this position.
⇒
Measure the distance between the coupling flange and the upper part of the
oil baffle with inside micrometer 94101 at the position indicated. The amount
by which distance ’X’ is smaller than that given on the sheet ’Check Dimen-
sions’ corresponds to the wear of the engine side thrust bearing pads
(AHEAD).
⇒
Displace the crankshaft axially until it rests on the thrust bearing pads for
ASTERN. Determine the total axial clearance with the inside micrometer.
Remark: If during checking or repair work any objects should fall into the thrust
bearing housing, they can be removed after dismantling cover 8. After major works
have been carried out in the thrust bearing space dismantle cover 8 for a check-up
on the thrust bearing housing. Remove any foreign matters through the opening.
