This dipper arm bushing is a critical wear component that facilitates smooth articulation and reduces friction between the dipper arm and the boom or bucket linkage. Manufactured from hardened steel, it provides superior wear resistance and load-bearing capacity compared to a worn or grooved bushing. Operators may experience increased play or looseness in the dipper arm, noisy operation, or difficulty in controlling bucket movements when this bushing is worn.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a worn dipper arm bushing is increased play or looseness in the dipper arm, often accompanied by audible clunking noises during operation. If ignored, this wear will accelerate, potentially damaging the pin and the mating surfaces of the boom or bucket. Continued operation risks uncontrolled movement and potential structural damage.
Ensure the pin bores are thoroughly cleaned of all old grease and debris before installing the new bushing. Avoid using excessive force or heat when pressing in the new bushing, as this can damage its integrity.
Inspect the dipper arm pin and the corresponding bores on the boom and bucket for wear or damage.
