11) Attach the eye bolt (94040 − M12) to the thrust bearing pad (2 or 3, Fig. 2 ).
12) Attach the chain blocks to the eye bolt (94040 − M12).
13) Attach the turning-out device (94155 or 94155A).
WARNING
Injury Hazard: Before you operate the turning gear, make sure
that no personnel are near the flywheel, or in the engine.
14) Operate the turning gear to turn the crankshaft in the applicable direction. At the
same time, operate the chain blocks (H1,H2) to keep tension on their chains.
Note: While the gear wheel (4) turns, the turning-out device 94155 moves the
thrust bearing pads. The first thrust bearing pad will come out.
15) Operate the chain blocks (H1, H2) to move the thrust bearing pad to the exhaust
side.
16) Lower the thrust bearing pad on to a stable area.
17) Do the procedure above for the remaining thrust bearing pads that you must
remove.
Note: If some of the thrust bearing pads ae removed, the remaining thrust
bearing pads will keep the crankshaft in position. If all thrust bearing
pads from the same side are removed, e.g. all the astern pads, the
crankshaft can move.
18) To prevent crankshaft movement, do as follows:
a) Get a piece of hardwood that has the same dimensions as a thrust bearing pad.
b) Put the hardwood in the position of the removed thrust bearing pads.
2. Installation
1) Make sure that the thrust bearing pads are clean.
2) Apply clean engine oil to the thrust bearing pads.
Note: You must install thrust bearing pads that you removed before in the same
positions. Use your notes and see the configuration for the correct
position of thrust bearing pads on engines with fixed pitch propellers
(FPP) and controllable pitch propellers (CPP) respectively.
3) If necessary, remove the piece of hardwood.
4) Attach the eye bolt (94040 − M12) to the thrust bearing pad (2 or 3).
5) Attach the chain blocks (H1, H2) to the thrust bearing pad (2 or 3).
6) Put the first thrust bearing pad in position. Make sure that the thrust pad touches
the turning-out device (94155 or 94155A).
7) Operate the turning gear to turn the crankshaft in the applicable direction.
8) Put the subsequent thrust bearing pad in position.
9) Do step 1 ) to step 7 ) above fro each thrust bearing pad.
Note: When all thrust bearing pads are in position the top, outer thrust bearing
pads must be at the equal height.
10) Remove the turning-out device (94155 or 94155A).
