CH-47672-A Frame Insulator Remover/Installer

1. Remove the frame from the vehicle. Refer to Frame Replacement .



2. Remove the upper frame insulator (1)



3. Assemble the CH-47672-A press as shown, on the frame insulator being removed.



4. Use the CH-47672-A press to remove the frame insulator from the frame.

1. Clean the frame insulator opening.
2. Apply thin coat of rubber lubricant GM P/N 1051717 (Canadian P/N 5728223), or equivalent to the inside of the frame insulator opening and to the insulator.



3. Install the CH-47672-A clamp to the bushing. Align the clamp screws with the split portion of the bushing. Position the edge of the clamp where the bushing chamfer blends with the straight section of the bushing. Alternately tighten the clamp screws until the split edges of the bushing are parallel and almost touching.

Important: The frame insulator splits must be aligned in a forward and rearward position relative to the vehicle.




4. Install the frame insulator to the front frame opening with the insulator splits aligned in a forward and rearward direction relative to the vehicle.



5. Assemble the CH-47672-A clamp and the frame insulator as shown to the frame.



6. Use the CH-47672-A press to begin installing the frame insulator into the frame. STOP and remove the CH-47672-A clamp (1) before the clamp becomes trapped between the CH-47672-A press and frame.



7. Use the CH-47672-A press to finish installing the frame insulator into the frame.

Important: Inspect and confirm that there is NO visible gap between the insulator and the frame.




8. Remove the CH-47672-A from the insulator and frame. Inspect and confirm that the insulator (2) is in direct contact with the frame (1).



9. Install the upper frame insulator (1)
10. Install the frame to the vehicle. Refer to Frame Replacement .
