Common Use Case or Symptoms: Use when the dipper arm to bucket bushings are worn, elongated, or causing excessive play at the arm-to-bucket pivot — worn bushings at this position allow the bucket to shift side-to-side during digging, accelerate pin wear, and reduce bucket control on applicable Hitachi and John Deere excavators.

• ✅ Internal Grease Groove: The internal grease groove ensures lubrication is distributed evenly across the full bearing surface — extending service life at this high-load pivot point.
• ✅ Made in the USA: Manufactured from 4140 steel alloy heat treated to 65 Rockwell hardness — the same material and hardness spec used in OEM excavator linkage components for maximum wear life.
• ✅ Two Required Per Machine: The dipper arm to bucket position uses two bushings — order accordingly to complete the job in one shipment.
