The water side of the pump is provided with a mechanical shaft
seal. The ring (4) rotates along with the shaft and seals against
it with the O-ring. The spring presses the rotating ring against a
fixed ring (3) which seals against the housing with the O-ring (7).
Possible leak-off water from the sealing can flow out through an
telltale hole in the bottom of the pump.

19.3.2 Maintenance
Normal maintenance operations, like removal of impeller or
replacing the mechanical seal, can be done without removing the
complete pump from the engine.
Check the pump at intervals according to the recommendations
in chapter 04. or, if water and oil leakage occurs, immediately.
Check that the telltale hole is open every now and then.
