6. Every 400 hours:
Checking the sacrificial anodes
(Only engines with heat exchanger)
- Empty the sea water circuit and check the sacrificial anodes. There
are 2 of these, positioned as shown.
- Scrape off all loose material on the sacrificial anode.
- Renew if less than half of the sacrificial anode is left.
A new sacrificial anode is 63 mm long with a diameter of 17 mm.
Note:
If the sacrificial anodes are very corroded they need to be
checked more often, for example every 200 hours.
7. Every 400 hours:
Checking the sea water pump impeller
(Only engines with heat exchanger)
- 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 worn or damaged.
Note:
If the impeller must be renewed frequently, the cleaning of the
sea water needs to be improved.
Renewing the impeller
- Pull out the impeller with puller 98 482 (Scania special tools).
- 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
periods of stoppage. Also see "Preparations for storage".
