Lincoln Electric IM870-A manual Water Separator Element, Secondary Fuel Filter

D-3 MAINTENANCE D-3

1.Close the fuel shutoff valve located under the fuel tank.

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 directly under the center cap in the upper cavity of the filter header. Use a small screwdriver (or simi- lar 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 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 located under the fuel tank.

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.

4.Slide the new element onto the grommet post on the bottom of the filter header until the element no longer easily moves up into the filter header. Now rotate the element (may take almost 1 full turn) with a slight upward pressure until the element begins to further engage the header. With the proper orientation now established apply additional pressure to seat the ele- ment in the filter header. You should feel the element “pop” into place when properly seated.

Note: The element will only go on one way. Never use excessive force when mounting the element to the header.

5.Slide the quick change ring up over the element and rotate counter clockwise until an audible click or pop is heard. If you do not hear the click you have not rotated the ring far enough and the element is not in the locked position. Another indication that the ring is in the locked position is that one set (it doesnʼt matter which one) of arrows located on the outside of the ring should be located directly under the air vent valve.

6.Open the fuel shutoff valve.

7.Open the air vent valve on the front of the filter header until fuel emerges free of air bubbles and then close the air vent valve.

Note : Consult your engine operation manual for infor- mation on air bleeding the entire fuel system.

SECONDARY FUEL FILTER

The Secondary Fuel Filter has a quick change element mounted to the engine similar to the Water Separator. Consult your engine operation manual for complete infor- mation on service intervals and element changing proce- dures.
