SERIES 60 AIR SEPARATOR FILTER ELEMENT (MARINE)

The closed breather system consists of an air separator assembly mounted to the inlet side of the turbocharger. See Figure 35497 . ‪

Typical Air Separator System

To operate efficiently, air separator filter and vacuum limiter must be properly maintained. ‪

  • Clean and oil the filter element and vacuum limiter every 250 hours of engine operation or once a year, whichever comes first. Refer to section , refer to section , and refer to section .

    Note: Filter element and vacuum limiter must also be cleaned and oiled any time the restriction gage shows red.

  • Filter element must be replaced after three cleanings.
  • Replace vacuum regulator/limiter every 1000 hours of engine operation or every two years, whichever comes first.

    NOTICE

    Failure to properly clean the engine room may allow loose debris to plug air separator elements. Plugging can lead to high air inlet restriction, causing reduced engine performance and/or engine damage caused by engine overheating. ‪

    Note: For best cleaning results, and to avoid damaging filter elements, Walker Cleaning and Re-oiling Kit must be used. This kit is available from Walker Engineering supply distributors or directly from manufacturer:

Pre-Clean Air Separator Filter Element

Perform the following procedures to clean and re-oil the air separator filter element: ‪

NOTICE

Failure to clean the air separator filter element and the vacuum regulator/limiter will affect the operation of the air separator and may cause reduced engine performance and/or engine damage caused by engine overheating. ‪

Note: A filter that is damaged or clogged with soot due to an exhaust leak may not be able to be cleaned to maximum air flow condition. Replacement of element may be necessary.

  1. Remove filter element from air separator by detaching the end cap. On some installations this is accomplished by removing the end cap bolt. Other installations require removal of the end cap attaching springs.

    Note: Filter elements and vacuum limiters must also be cleaned and oiled when the air inlet restrictions turns red . This indicates the maximum allowable system restriction has been reached.

  2. Tap element to dislodge any large, imbedded particles of dirt.
  3. Gently brush outside of element with soft bristle brush, such as a paint brush, to remove smaller particles of dirt.
    1. If complete cleaning is impractical at this time, re-oil and install element. Refer to section for oiling procedure.
    2. If complete cleaning is practical at this time, refer to section and follow cleaning and oiling procedure.

Cleaning of Air Separator Filter Element

Perform the following procedures to clean air separator: ‪

  1. Spray Walker cleaning solution onto element and let soak 10 minutes.

    NOTICE

    To avoid filter damage, do not clean with gasoline, steam, high pressure water or air, caustic solutions, strong detergents, or parts cleaning solvents. ‪

  2. Rinse element with clean, low pressure, fresh (not salt) water. Rinse from clean side (inside) to dirty side.

    NOTICE

    To avoid filter damage, do not use compressed air, open flame, ovens, or heat dryers. Excess heat will shrink the filter element, and compressed air will blow holes through it. ‪

  3. Shake off excess water and allow element to dry naturally.

    NOTICE

    To avoid filter damage, do not use transmission fluid, motor oil, diesel fuel, WD-40 or other lightweight oil. ‪

  4. Squeeze Walker air filter fluid out of the bottle and across the top of each pleat. Make one pass per pleat.

    Note: Filter effectiveness is reduced if the element is used without re-oiling.

  5. Allow oil to work into element for 20 minutes.
  6. Re-oil any white spots on the element.
  7. Install air separator filter element.

Clean Vacuum Regulator Filter Element

The vacuum regulator filter can be cleaned without removing the regulator from the system. ‪

  1. Detach filter using a standard blade screwdriver.
  2. Refer to section , and follow same pre-clean procedure.
  3. Refer to section , and follow same cleaning procedure.

Clean Vacuum Limiter Filter Element

Clean vacuum limiter filter element as follows: ‪

  1. Remove entire vacuum limiter assembly. Do not detach filter element.
  2. Refer to section , and follow same pre-clean procedure.
  3. Refer to section , and follow same cleaning procedure.
