A rework procedure for B, CB, DB and TB buckets is now available for the cracking of certain welds that are located on the top plate assembly of the bucket. The rework procedure describes the repair process for certain excavator buckets. Refer to Special Instruction, REHS3874, "Rework Procedure for Weld Cracks of B, CB, DB and TB Buckets for Certain Excavators".

Dealers need to supply and fabricate steel plates per Special Instruction, REHS3874. Use structural steel ASTM A572 or equivalent. The length and thickness of the steel plate will vary depending upon the bucket. There are no additional required parts for the rework process.
