SERIES 60 OIL FILTER ADAPTOR

The oil filter adaptor is located on the right side of the engine and is attached to the oil cooler. ‪

The 1991 and later engines have a separate oil filter bypass adaptor. See Figure 20440 . ‪

Oil Filter Adaptors, Bypass Valve and Related Parts (1992 & Later)

A bypass valve in the filter adaptor opens at approximately 124-145 kPa (18-21 lb/in.2 ) pressure differential, and will bypass the oil should the full-flow filters become plugged. ‪

Repair or Replacement of Oil Filter Adaptor

To determine if repair is possible or replacement is necessary, perform the following procedure. See Figure 21753 . ‪

Removal of Oil Filter Adaptor

Precleaning is not necessary. ‪

Remove the oil filter adaptor as follows: ‪

EYE INJURY

To avoid injury from flying parts when working with components under spring tension, wear adequate eye protection (face shield or safety goggles).

  1. Remove the snap ring, using J 23432 .
  2. Withdraw the spring and bypass valve (engines built prior to 1993). See Figure 20440 .
  3. Remove the pipe plugs.

Cleaning the Oil Filter Adaptor

Clean the oil filter adaptor as follows: ‪

  1. Clean all of the oil filter adaptor components in fuel oil.

    EYE INJURY

    To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 40 psi (276 kPa) air pressure.

  2. Dry the parts with compressed air.
Inspection of Oil Filter Adaptor

Inspect the oil filter adaptor as follows: ‪

  1. Inspect the bypass valve for movement. Check to see if the bypass valve moves freely in the adaptor.
    1. If the bypass valve binds, replace it with a new part.
    2. If the bypass valve does not bind, reuse the part.
  2. Inspect the components for wear or damage. Check to see if the valve or the filter adaptor bore are scored.
    1. If the valve and the filter adaptor bore parts cannot be cleaned with a fine emery cloth, replace with new parts.
    2. If the valve and the filter adaptor bore parts can be cleaned with a fine emery cloth, reuse the parts.
  3. Inspect the spring for damage. Check for pitting or fractures.
    1. If spring is damaged, replace the component.
    2. If spring is not damaged, reuse the component.

Assembly of Oil Filter Adaptor

Assemble the oil filter adaptor as follows: ‪

  1. Install bypass spring and bypass valve into the oil filter adaptor.
  2. Install snap ring using J 23432 .
  3. Install oil filter adaptor inserts, if removed.
  4. Install the pipe plugs:
    1. Apply a sealant such as, Loctite 620, (or equivalent) to the threads that will engage the adaptor.
    2. Wipe off any sealant remaining exposed on the threads.
    3. Torque all three pipe plugs to 129-161 Nm (95-119 lbft).
  5. Coat new O-rings with petroleum jelly.
  6. Install the O-rings in the recesses in the oil filter adaptor.

Installation of Oil Filter Adaptor

Install oil filter adaptor as follows: ‪

NOTICE:

Failure to tighten oil filter adaptor mounting bolts to the required torque may lead to a loss of lubricating oil during engine operation. Inadequate lubrication can result in severe engine damage. ‪

FIRE

To avoid injury from fire, contain and eliminate leaks of flammable fluids as they occur. Failure to eliminate leaks could result in fire.

  1. Install the oil filter adaptor to the cylinder block and fasten as follows:
    1. Torque the four M10 mounting bolts on current two-element oil filter adaptor to 58-73 Nm (43-54 lbft).
    2. Torque the six M8 mounting bolts on former three-element oil filter adaptor to 30-38 Nm (22-28 lbft).
  2. Install full-flow oil filter(s). Refer to section .
  3. Refer to section for verification of proper oil filter adaptor installation.
