Komatsu Part BUSHING 424-70-11820

—

Product Overview

The 424-70-11820 BUSHING is a genuine Komatsu OEM replacement bushing. Bushings are the hard-working wear components in pivot joints — they take the friction and surface wear so the pin and housing bore don't have to.

When to Replace

• Excessive clearance between the bushing bore and the pin
• Oval or elongated bore shape from directional loading
• Surface cracks, galling, or scoring visible
• Grease leaking past the bushing instead of through the proper clearance
• The pin shows a wear step — if the pin is worn, the bushing is worn too
