B - Final Fuel Filter Element

C - Drain Plug

D - Bleed Plug

E - Water Separator Bowl

F - Primary Fuel Filter Element

Engines may be equipped with dual fuel filters: a primary filter (F) with water bowl, and a final filter (B). Both filters are replaced at the same 500-hour interval or every 12 months.

CAUTION: Escaping fluid under pressure can penetrate the skin causing serious injury. Relieve pressure before disconnecting fuel or other lines. Tighten all connections before applying pressure. Keep hands and body away from pinholes and nozzles which eject fluids under high pressure. Use a piece of cardboard or paper to search for leaks. Do not use your hand.

If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type injury or gangrene may result. Doctors unfamiliar with this type of injury may call the Deere & Company Medical Department in Moline, Illinois, or other knowledgeable medical source.

IMPORTANT: Replace fuel filter elements anytime audible alarm sounds and trouble codes indicate plugged fuel filters (low fuel pressure). If no alarm sounds during the 12 month service interval, replace elements at that time, or after 500 hours operation, whichever comes first.

  1. Close fuel shut-off valve, if equipped.

  2. Thoroughly clean fuel filter assemblies and surrounding areas.

  3. Disconnect water sensor wiring from primary fuel filter.

  4. Loosen drain plugs (C) and drain fuel into a suitable container.

  5. NOTE: Lifting up on retaining rings (A) as they are rotated helps to get them past raised locators.

    Firmly grasp the retaining rings (A) and rotate them clockwise 1/4 turn (when viewed from the top). Remove ring with final fuel filter element (B) and with primary fuel filter element (F).

  6. Loosen ring and remove water separator bowl (E) with primary fuel filter element. Drain and clean bowl. Dry bowl with compressed air.

  7. Inspect filter mounting base for cleanliness. Clean as required.

  8. NOTE: Raised locators on fuel filter canisters must be indexed properly with slots in mounting base for correct installation.

    Install new filter elements onto mounting bases. Be sure elements are properly indexed and firmly seated on bases. It may be necessary to rotate filters for correct alignment.

  9. Align keys on filter element with slots in filter base.

  10. Install retaining ring onto mounting base making certain dust seal is in place on filter base. Hand tighten ring counterclockwise (about 1/3 turn) until it “snaps” into the detent. DO NOT overtighten retaining ring.

  11. NOTE: The proper installation is indicated when a "click" is heard and a release of the retaining ring is felt.

    A plug is provided with the new element for plugging the used element.

    Install water separator bowl on primary fuel filter and tighten ring.

  12. Reconnect water sensor wiring.

  13. Open fuel shut-off valve and bleed the fuel system. (See BLEEDING FUEL SYSTEM in Service As Required Section.) Tighten bleed plug (D).
