Dual Vibration Dampers
Illustration 2 g00609906Note: The later vibration dampers have finned covers. Be careful not to damage the fins.
Remove two bolts (1) that hold vibration damper (2). Install Tooling (B) in the adapter.
Install a suitable lifting device through the center of vibration damper (2). The weight of a narrow vibration damper is approximately 288 kg (639 lb). The weight of a wide vibration damper is approximately 402 kg (886 lb).
Remove the rest of bolts (1) that hold vibration damper (2) to the adapter. Slide the vibration damper along Tooling (B) and remove vibration damper (2). Remove Tooling (B).
Illustration 3 g01294011
Remove the two top bolts that hold adapter (3) and vibration damper (4). Install Tooling (A).
Remove the rest of the bolts and remove adapter (3).
Illustration 4 g01294025
Move vibration damper (4) onto Tooling (A) until a suitable lifting device can be placed through the center of vibration damper (4).
Install a suitable lifting device through the center of vibration damper (4). The weight of a narrow vibration damper is approximately 288 kg (639 lb). The weight of a wide vibration damper is approximately 402 kg (882 lb). Remove vibration damper (4).

Remove spacer (5). Note: For information on rebuilding vibration dampers, refer to Reuse and Salvage Guidelines, SEBF8152, "Procedures to Rebuild Vibration Dampers for 3600 Family of Engines".Installation Procedure
Illustration 6 g00609918
Install Tooling (A) in the crankshaft.
Place spacer (5) in position on Tooling (A). Be sure that the heads of the bolts that hold the adapter assembly together fit into the holes in spacer (5).
Illustration 7 g01294025
Install a suitable lifting device through the center of vibration damper (4). The weight of a narrow vibration damper is approximately 288 kg (639 lb). The weight of a wide vibration damper is approximately 402 kg (882 lb).
Place vibration damper (4) on Tooling (A). Align the Timing Mark for the TC position on vibration damper (4) with the Timing Mark on the crankshaft. Be sure that the bolt holes are aligned. Be sure that the heads of the small bolts at the center of the vibration damper fit into the spacer. Install vibration damper (4).
Illustration 8 g01294011
Install adapter (3) on Tooling (A). Be sure that the bolt holes are aligned. Be sure that the heads of the small bolts at the center of vibration damper (4) fit into adapter (3).
Install the bolts that hold the adapter to the crankshaft. Tighten the bolts in a diagonal pattern to a torque of 1350 150 N m (1000 110 lb ft).
Remove Tooling (A) and install Tooling (B) in adapter (3). Note: Ensure that the outer vibration damper is installed in the correct orientation. The Timing Mark for the TC position should be turned 36 degrees in a clockwise direction from the Timing Mark for the TC position on vibration damper (4). The direction is determined when the dampers are viewed from the front of the engine.
