Komatsu Part BUSHING 428-70-11895

—

Product Overview

The 428-70-11895 BUSHING is a genuine Komatsu OEM replacement bushing from the 428 prefix series. Bushings provide the controlled wear surface between pins and structural bores at pivot points throughout your machine — they're designed to wear out over time, protecting the far more expensive pin and housing from damage.

When to Replace

• Rocking the connected parts reveals movement — clearance has opened up beyond the design limit
• The bushing bore shows oval or elongated shape rather than round — wear concentrated in the primary load direction
• Surface cracking, galling, scoring, or embedded contamination visible on the bore surface
• Grease leaks past the bushing face — the clearance gap has opened too wide
• The mating pin shows any wear ridge — pin and bushing wear together
