Rework Procedure

1. One or both of the 438-7435 (PL83/87) and 449-4859 (PL72) Plate As. may not be oriented correctly on the counterweight rack.

2. Use a square to check the orientation of the plates. If the plate(s) are not oriented correctly, you may not be able to slide the counterweight retention rod through the counterweights and then thread the rod into the 438-7435 (PL83/87) and 449-4859 (PL72) Plate As.

3. Cut off the 438-7435 (PL83/87) and 449-4859 (PL72) Plate As. as needed and reposition so that it is aligned with the counterweights. Weld back in place. Use a 12 mm fillet weld as shown in Image 1.3.1 below to reattach the Plate As. Refer to Images 1.3.2 through 1.3.4 for dimensions to locate the Plate As. Dimensions are from the 03 datum line on each drawing.
