  2. Tilt the hood.
  3. From underneath the front of the engine, remove the bumper beam. Push the support angle bracket fairing down to create an opening in the bumper.
  4. Remove the three drive belts. Refer to section .
  5. Remove the vibration damper from the engine through the opening in the bumper. Refer to section .
  6. Check the seal for wear at the places where it contacts the crankshaft.

    Note: When drilling holes for screws, make sure to coat the drill bit with grease to catch the shavings.

  7. Using sheet metal screws and the front seal puller, remove the front radial seal from the front cover housing. See Figure 41933 .

    PERSONAL INJURY

    Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.

    • Always start and operate an engine in a well ventilated area.
    • If operating an engine in an enclosed area, vent the exhaust to the outside.
    • Do not modify or tamper with the exhaust system or emission control system.
  7. Check the engine oil pressure at idle. Engine oil pressure at idle should be at least 50 kPa (7 psi).
  8. Close the hood, and remove the chocks from the tires.
