Rework Procedure

Show/hide table

1. Place window latch in vent position as shown in picture below. Window latch consists of handle (1), keeper (2), 131-3987 screws (3), and 177-4877 shims (4). Shims may not be installed on all window latch assemblies.

Image1.1.1

2. Apply light pressure against window.

3. If latch holds window in vent position, no rework is required. If latch does not hold window in vent position, proceed to step 4.

4. Remove the two 131-3987 screws from the keeper for the window latch.

5. With the window in the vent position, relocate the keeper toward handle in direction of arrow A to acheive 9+/-2mm engagement at point B.

Image1.2.1

6. Mark the positions for the new holes.

7. Use the 9/64 inch drill bit in order to drill two new holes at the marked positions.

8. Reinstall keeper and 177-4877 shims (as needed) using the two 131-3987 screws and tighten. Cab window sealing may be reduced due to moving the keeper for rework. If necessary, shims may be used to improved cab window sealing.
