Problem
The rops and frame mounting pad welds need to be inspected for cracks on certain CS431B, CP433B, and CS433B Compactors. If cracks in the ROPS are found, a new rops structure must be installed. Otherwise, repairs will be made to the frame if cracks are found.

Rework Procedure
Inspect the welds for cracks in the ROPS and frame mounting pads at the 12 locations shown in Illustration 1 and 2. A 4C4736 Crack Detection Liquid Penetrant Kit can be used to assist in the inspection. ("L" - left side, "R" - right side)
The weld sizes should be measured and recorded at each of the 12 locations for both the frame and the ROPS. The weld sizes at each of the locations shown, along with the ROPS Identification Number, will be required for filling out the warranty claim.

ROPS Identification Number
Identify and inspect the locations shown in Illustration 2. Record if there is or is not a presence of cracks and corresponding weld size for each of the locations.

If cracks are found in the mounting pad welds, the ROPS will need to be replaced and new mounting hardware used when installing. See Illustration 3 for the tightening sequence. Tightened the nuts to a torque of 265 ± 35 lb ft.
If cracks are found in the welds for the frame mounting pads or the weld sizes measured is less than 6 mm, corrective action will be required.
1. Cracks should be repaired by following the guidelines set forth in Special Instructions SEHS6929.
2. Weld sizes should be increased to a finish weld size of 10 mm. Weld size less than 6 mm should be increased to a finish weld size of 10 mm by adding additional weld over the existing weld.
3. In repairing cracks or increasing weld size, it is recommended that the ROPS be lift installed and bolted to the frame mounting plate. Some bolts will need to be removed to allow for adequate access to the mounting pad, however at least three bolts should remain in place. This will help to minimize distortion of plate from welding.
4. One weld length (example: from R1 to R5 or from R5 to R4) should be done at a time. Welds should be wrapped around the corners.
5. After welding, the areas should be cleaned and painted. New mounting hardware should be installed and tightened to a torque of 265 ± 35 lb ft in the sequence shown in Illustration 3.
