Don’t Ignore Worn Bushings on Your Excavator—They Can Cost You More Than You Think

Excavator bushings may seem like small parts, but they play a huge role in machine performance. Every time your boom, stick, or bucket moves, bushings absorb the stress. Over time, these components wear down. If you wait too long to replace them, the damage spreads—quickly.

Worn bushings lead to increased play in joints. This creates slop in movement, reduced digging accuracy, and more shock on pins and structural parts. Operators often notice clunking noises, jerky movement, or uneven arm control. These are red flags. If ignored, the wear can spread to expensive components like the boom or cylinder eyes.

Bushings also protect against vibration and friction. When worn, metal-on-metal contact increases. Heat builds up. Lubrication can’t do its job. That’s when pins begin to score or seize. Once that happens, you’re looking at full pin and bushing replacements—often with downtime.

The real danger? Cracks. Once joints start to loosen, the frame or mounting ears may crack under repeated load. Repairing structural damage isn’t just expensive—it can take your machine out of action for weeks.

So, when should you replace excavator bushings? The simple answer: when you first notice excess movement. Measure pin-to-bushing clearance regularly. If movement exceeds OEM tolerance, it’s time to act. Don’t wait for failure. Scheduled bushing replacement keeps your machine precise and productive.
