Remove 416-9256 Plate (A) that is located on the engine door on the rear of the machine by removing the two 113-8694 Bolts (B), the two 8T-4205 Hard Washers (D), and the two 5C-2890 Nuts (C).

After removing 416-9256 Plate (A), ensure that the mounting locations on the horizontal Plate on the rear door are slots not holes. If these are holes, then drill another hole of 14 mm (0.55 inch) in diameter directly behind each hole and towards the rear of the machine. Then use a tool to grind off any excess material to create the slots. This change was incorporated in order to be able to move the Camera rearward to improve visibility. Refer to Illustration 6.

Illustration 6	g03612647

The following table contains the machines with holes instead of slots.

The removal of the plate will uncover a hole on the back door of the machine. Mount 336-6684 Camera Gp (1) so that the lens of the camera faces this hole and enables a clear view towards the rear of the machine. At the same time, insert the included 6V-7357 Bolts on top of the camera group upward and through the slots on the back door where the removed plate was previously attached. Place one of the included 129-3178 Locknuts and 9X-8256 Washers on each bolt and then tighten to 6 ± 1 N·m (4.4 ± 0.75 lb ft). This action will secure camera group (1) to the back door of the machine.

Note: The 6V-7357 Bolts, 9X-8256 Washers, and 129-3178 Locknuts are included in 336-6684 Camera Gp (1). These components replace removed bolts (B) and nuts (C).

Note: Inorder to adjust the aim of the lens of the camera, use the included 2.5 mm (0.10 inch) hex key and tighten the screws on the sides of camera (1) to 0.9 ± 0.1 N·m (0.66 ± 0.07 lb ft) after obtaining the desired lens position. The aim arrow on top of the CAT logo stamped on the lens area should be vertical and pointing upward. The lens of the camera should be planar to the back door bezel face.
