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 dial gauge 8. This is then checked against the figure marked on the page
’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.
Remark: After major works have been carried out in the thrust bearing space dis-
mantle cover 7 for a check-up on the thrust bearing housing. Remove any foreign
matters through the opening.
