[Public-List] Still leaks - seating the pump

[John Birch]

Hey Gord,

 In my Westerbeke tech manual, which I know is a different motor but the 
Sherwood pump and hookup is quite similar to the Oberdorfer, in the WB 
Manual, they speak of needing to shim with gaskets sufficient clearance do 
that the pump drive is not compressing hard into the engine coupling drive 
slot. They say 1-3 gaskets my be needed to achieve that clearance so that 
there aren't oil leaks or the risk of damaging the pump seal allowing water 
to flow into the oil system.

During tightening they suggest only hand tight, then jog the engine without 
starting, to ensure the pump coupling seats squarely before final tightening 
to pattern.

May well be a similar story with the A4 as their pump configurations and 
couplings appear almost identical.

Anyway, just a thought.

Good luck Gord

John
