6728999 Pivot Pin Bushing for Bobcat S250, S300, T250, T300

   The 6728999 bushing is manufactured from hardened, high-carbon steel to withstand the immense breakout forces of Bobcat’s large-frame loaders. It features precision-machined internal grooves (cross-hatching) designed to distribute grease evenly around the pin, reducing friction and preventing "seizing" in high-dust or muddy environments.

Q1: How can I tell if my 6728999 bushings need to be replaced?

A: Look for visible "play" or movement in the joints when curling the bucket or lifting the arms. If you hear a "clunking" sound or see metal shavings around the pivot points, the bushing has likely worn through, and the pin is now contacting the arm directly.

Q2: Should I replace the pin at the same time as the 6728999 bushing?

A: Yes. If a bushing has failed, the pin usually has irregular wear patterns. Installing a new bushing with a worn pin will cause the new bushing to fail prematurely.

Q3: What is the best way to remove the old bushing?

A: These are press-fit. Most technicians use a heavy-duty hydraulic press or a specialized "bushing puller" tool. In the field, some use a welder to run a bead inside the bushing (which causes it to shrink as it cools) for easier removal.
