Worn bushes accelerate pin wear and increase slop in the excavator undercarriage — left unchecked, the damage extends to costly structural components. This bucket bush 4pc130 22b-70-23660 is manufactured to OEM dimensional specifications for correct interference fit and service life.

– Compatible with OEM pins; no bore re-machining required after press fitting

**Material & Treatment:**
– Oil-impregnated sintered bronze or high-strength steel depending on application

– Corrosion-protected finish for pre-installation storage in site conditions

**Fitting Notes:**
– Press fit using proper tooling — hammering damages bore geometry
