Grease lubricated shaft seal
All engines
connection except
D9/D11:
Water from reverse gear
oil cooler.
Hose/pipe diam.
0 mm (3/8")
Another way, which is common in planing boats, is to
feed the shaft seal with water taken from the cooling
system of the engine. Make sure to take the water af-
ter the cooling circuit of the engine and not bleed off
too much water in a boat with wet exhaust system. If
too much water is lost through the outlet to the shaft
seal, the exhaust hose might be overheated. A guide-
line is to install a 0 mm (3/8") hose from the reverse
gear oil cooler.
It is important to check that the water lubrication is
adequate, also at full speed, while testing a new in-
stallation.
NOTE! For D6, the oil cooler is delivered separately.
For installation instructions, contact Volvo Penta.
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.
