MAINTENANCE

7.Inspect for holes and tears by looking through the element toward a bright light. Check for damaged gas- kets or dented metal parts. Do not reuse damaged ele- ments. Protect element from dust and damage during drying and storage.

8.Reinstall air filter element.

After six cleanings replace air filter. A cleaned filter will have approximately 70% of the life of a new filter ele- ment. A restricted filter element may not appear exces- sively dirty.

FUEL FILTERS

WARNING

When working on the fuel system

• Keep naked lights away, do not smoke !

•Do not spill fuel !

------------------------------------------------------------------------

The Commander 500 is equipped with a Fuel Pre- Filter/Water Separator Assembly located before the lift pump and a Secondary Fuel Filter located after the lift pump and before the fuel injectors. The Fuel Pre- Filter/Water Separator is mounted to the engine block just below the lift pump. The Secondary Fuel Filter is mounted directly to the engine just above the oil filter.

FUEL PRE-FILTER/WATER SEPARATOR ASSEM- BLY

The pre-filter is a 150 micron screen designed to pro- tect against gross fuel contamination of the water sep- arator element and the Secondary Fuel Filter. If the pre-filter becomes plugged it may be removed, inspect- ed, cleaned and reinstalled. In general this only needs to be done with each water separator element change (about every 1,000 hrs.) However if at any time exces- sive fuel contamination is suspected or a sudden fall- off in engine performance is detected the pre-filter screen should be inspected and cleaned. Follow the following procedure:

1.Close the fuel shutoff valve (Lever should be per- pendicular to the hose) located on the side of the Fuel Pre-Filter/Water Separator Assembly.

2.Unscrew the cap ring located on the top of the filter header and remove the plastic center cap and O- ring.

3.Remove the large white volume plug located direct- ly under the center cap in the upper cavity of the fil- ter header. Use a small screwdriver (or similar device) to lift the plug part way out of the cavity to assist with its removal.

Be careful not to damage the pre-filter screen with the tool used to remove the plug.

4. Using a pair of pliers, gently tug on the pull tabs of the pre-filter screen in an alternating pattern to gradually remove the pre-filter screen.

5.Brush off any debris and rinse in diesel fuel.

6.Re-install the pre-filter screen into the upper cavity of the filter header making sure the four pull tabs are pointing up. Putting your fingers on the pull tabs, push down evenly until the lower body of the pre-filter screen contacts the floor of the upper cav- ity.

7.Re-insert the large white volume plug into the upper cavity.

8.Place the O-ring onto the angled seal surface of the filter header and re-install the plastic cap. Make sure its flange rests on the O-ring.

9.Screw on the cap ring and tighten hand tight.

10.Remember to open the fuel shutoff valve (Lever in line with the hose) before starting the engine.

WATER SEPARATOR ELEMENT

The water separator element is a two stage filter with a special filtration/water separating media, and an expanded water reservoir providing maximum protec- tion against water in the fuel. The recommended change interval for the water separator element is 1,000 hours. The procedure for changing the element is as follows:

1.Close the fuel shutoff valve (Lever should be per- pendicular to the hose) located on the side of the Fuel Pre-Filter/Water Separator Assembly.

2.Rotate the quick change ring (located just below fil- ter header) clockwise approximately 1/2 turn and slide it down and off of the element.

3.Grasp the element and pull down with a slight rock- ing motion to remove the element from the grom- met post on the bottom of the filter header.
