A special tool, Engine Cranking Tool (J 46167 or 407 589 00 63 00) is required for this procedure. ‪

Crankshaft Vibration Damper Removal

Remove the crankshaft vibration damper as follows: ‪

  1. Remove the drive belts from the alternator, coolant-pump, idler, and air-conditioner compressor pulleys, as installed. Refer to section .
  2. Remove the inspection cover from the flywheel housing and install the engine cranking tool (J 46167 or 407 589 00 63 00) , with the locking pin in place. Refer to section .
  3. To gain access to the vibration damper, remove the lower mounting bolts from the bottom of the front fairing/bumper.
  4. Remove the mounting bolts from the vibration damper. Drop the vibration damper down below the radiator and remove it from the engine. See Figure 41961 .

    Vibration Damper Removal

  5. Remove the oil deflector from the crankshaft.
  6. Inspect the vibration damper for signs of wear, dents, deformation, or other signs of damage. Replace the damper if the belt contact surface is worn or damaged.

    Note: The vibration damper has a crankshaft pulley bolted to it to accommodate two additional drive belts. It is not necessary to disassemble the vibration damper unless the crankshaft pulley is damaged and needs to be replaced.

Crankshaft Vibration Damper Installation

Install the crankshaft vibration damper as follows: ‪

Note: Check the crankshaft front seal for oil leaks. If leakage is found, replace the front seal. Refer to section .

  1. Install the oil deflector. Make sure the rim is facing the engine.
  2. Install the vibration damper on the crankshaft, as removed. Tighten the bolts 200 Nm (148 lbft). Use an alternating sequence until all six bolts are tight.
  3. Install the lower mounting bolts on the bottom of the front fairing/bumper, as removed.
  4. Remove the engine cranking tool from the flywheel housing and install the inspection cover. Tighten the inspection cover bolts 25 Nm (18 lbft).
  5. Install the drive belts on their pulleys, as removed. Refer to section .
