  4. Remove and discard the oil filter.
  5. Remove the 6 bolts and the oil pump.
    WARNING
    Do not reuse the oil pump seal. A new service seal must be installed.
  6. Remove and discard the oil pump seal.
  7. Remove and inspect the oil pump drive gear, the driven gear and the cover. Install new components if necessary.
  8. Inspect the face of the oil pump for flatness.
To install:

NOTE
Lubricate the new O-ring seal with clean engine oil.

  1. Clean and inspect the mating surfaces and install a new O-ring seal.
    WARNING
    The oil pump must be primed prior to starting the engine.
  2. Install the oil pump and loosely install the 3 bolts. Tighten the bolts in the sequence shown to 10 Nm (89 inch lbs.).
    WARNING
    Make sure the O-ring is in place and not damaged. A missing or damaged O-ring can cause foam in the lubrication system, low oil pressure and severe engine damage.


    NOTE
    Install a new O-ring and lubricate with clean engine oil.
  3. Install the pick up tube spacer, oil pump screen and pickup tube and the 3 bolts. Tighten bolt 1 to 25 Nm (18 ft. lbs.). Tighten bolts 2 to 10 Nm (89 inch lbs.).
  4. Install the oil pan.
  5. Install the timing drive components.
6.0L Diesel Engine
  1. Before servicing the vehicle, refer to the Precautions Section.
  2. With the vehicle in Neutral , position it on a hoist.
  3. Disconnect the battery ground cable(s).
  4. Remove the cooling fan
  5. On vehicles with dual alternator, perform the following:
    1. Remove the dual alternator accessory drive belt.
    2. Remove the bolts and the dual alternator pulley.
  6. Remove the accessory drive belt.
  7. Check the crankshaft vibration damper runout.
  8. Remove the paint from the face of the crankshaft vibration damper at four points 90 degrees apart.
  9. Attach dial indicator 100-002 to the cylinder block. Position the tool on one of the unpainted surfaces.
  10. Using a suitable tool, pry the crankshaft forward. Zero the dial indicator.
    NOTE
    Pry the crankshaft forward only to eliminate possible error caused by crankshaft end play.
  11. Rotate the crankshaft 90 degrees. Pry the crankshaft forward. Record the measurement. Repeat at each unpainted surface.
  12. If the runout exceeds specification, install a new crankshaft vibration damper.
    CAUTION
    To avoid personal injury, support the vibration damper during mounting bolt removal. The damper can slide off the nose of the crankshaft very easily.
  13. Remove the bolts and the crankshaft vibration damper.
  14. Discard the bolts.
  15. Punch two holes in the seal.
  16. Using the special tool 303-D060, remove the crankshaft seal.
    NOTE
    Production engine will not have a wear sleeve.
  17. If equipped, remove the crankshaft damper wear sleeve using tool 303-762.
  18. Remove the bolts and the gerotor cover. Remove and discard the O-ring seal.
    NOTE
    Mark the front of the inner and outer gerotor for correct reassembly.
  19. Remove the inner and outer gerotors.
  20. Inspect the oil pump components and replace as necessary.
  21. Inspect the oil pump for excessive metal particles.
  22. Inspect the oil pump for gouging, cracks or deep scratches.
  23. Inspect the oil pump inner and outer gear rotors for damage or excessive wear.
To install:

NOTE
Install the gears with marks pointing outward.

  1. Lubricate the inner gear with lithium assembly grease and install onto the crankshaft. Lubricate the outer gear with lithium assembly grease and mesh with the inner gear rotor in the oil pump housing. Wipe off the excess assembly grease.
  2. Install a new O-ring seal.
  3. Install the gerotor cover and bolts. Tighten to 71 inch lbs. (8 Nm).

  4. Thoroughly clean the crankshaft front seal mounting surface.
  5. Apply Threadlock 262® to the outer circumference of the leading edge of the crankshaft.
    NOTE
    New seal and wear sleeve must not be separated.
  6. Using the special tool 303-361, install the oil seal and wear sleeve assembly.
    CAUTION
    To prevent engine damage, you must always install four new bolts when installing the vibration damper.


    NOTE
    Do not use anti-seize compounds, grease or any lubricants. Lubricants have an adverse effect on the torque results.
  7. Install the crankshaft vibration damper and bolts.
  8. Tighten the bolts in a criss-cross sequence as follows:
    1. Tighten the bolts to 50 ft. lbs. (68 Nm).
    2. Tighten the bolts an additional 90 degrees.
  9. Install the accessory drive belt.
