Grease lubricated shaft seal
Installation of stern tube and
shaft bearing
A
The grease is injected either with a grease cup fitted
to the seal assembly or from a remote greaser. The
bolt holding the seal should not be overtightened as
this may cause overheating and excessive wear on
the propeller shaft.
The fix point (A) is determined by required propeller
size etc.The engine can be used as a fixture to decide
the location of the stern tube and bearing. The engine
must be adjusted to its nominal position.
In serial production tailor-made fixtures are often used
instead of the engine to locate the stern bearing.
