Checking The Sacrificial Anodes - Scania PDE Operator's Manual

Checking the sacrificial an-
odes
• Empty the sea water circuit and check the sac-
rificial anodes.
• Scrape off all loose material from the anode.
• Renew if less than half the anode is left. A
new anode is 60 mm long with a diameter of
17 mm.
• If the sacrificial anodes are very corroded, the
inspection interval must be reduced
Checking the sea water pump
impeller
• Close the bottom valve if the sea water pump
is below water level.
• Drain the sea water circuit.
• Take off the sea water pump cap.
• Check that the vanes of the impeller are not
heavily splintered or damaged.
Note:
If the impeller must be renewed frequently, the
cleaning of the sea water must be improved.
Renewing the impeller
• Pull out the impeller using puller 98 482.
• Fit a new impeller and cap. Check that the cap
seal is not hard or damaged.
Note:
There should be a spare impeller on board.
The impeller can be deformed during extended
periods of inactivity. Renew the impeller before
starting or remove the impeller before longer pe-
riods of stoppage. See also "Preparations for
storage".
