72 Section 3 Scheduled Maintenance

3.5 Cooling System

Hot coolant and steam.

Can cause severe injury or death.

Before removing the pressure cap,

stop the generator set and allow it to

cool. Then loosen the pressure cap

to relieve pressure.

Fill system

before starting unit.

WARNING

Allow the engine to cool. Release pressure from the

cooling system before removing the pressure cap. To

release pressure, cover the pressure cap with a thick

cloth and then slowly turn the cap counterclockwise to

the first stop. Remove the cap after pressure has been

completely released and the engine has cooled. Check

the coolant level at the tank if the generator set has a

coolant recovery tank.

3.5.1

Impeller Inspection and

Replacement Procedure

See Section 1.1, Service Views for the location of the

seawater pump. Check and change the seawater pump

impeller at the interval specified in the service schedule.

Follow the instructions included with the impeller kit. If

the instructions are not included with the kit, use the

following procedure:

Impeller Inspection and Replacement Procedure:

Note:

Always keep a spare impeller on board. The

impeller can be deformed during extended

periods of inactivity. Replace the impeller before

starting or remove the impeller before longer

periods of stoppage.

1. Close the seacock.

2. Drain the seawater circuit as described in the

supplied Engine Operation Manual.

3. Remove the seawater pump cap.

4. Check that the vanes of the impeller are not heavily

splintered or damaged.

Note:

If the impeller requires frequent replacement,

improve seawater cleaning (refer to the Engine

Operation Manual).

5. Remove the impeller using a puller tool. See

Figure 3-1.

Figure 3-1

Impeller Replacement

6. When installing the new impeller, bend the vanes in

the same direction as on the old one.

7. Fit a new impeller and cap. Check that the cap seal

is not hard or damaged.

Note:

Cover (M6 x 12) 7.5 Nm.

8. Open the seacock.

9. Start the generator set and check for leaks.

10. Stop the generator set and repair leaks or replace

damaged or worn components.
