K120070 KMAX K70 Weld-On Center Adapter for 50 Mm Bucket Lip

The K120070 weld-on adapter provides the connection between a bucket lip and replaceable KMAX 70-series bucket teeth.

Designed as a Type 1 center adapter with a 1-1/2-leg profile, it fits a nominal 2-inch or approximately 50.8 mm bucket lip. Its verified 30-degree mounting profile and K70 nose geometry allow it to accept compatible K70 tooth profiles for different excavation and loading conditions.

K120070 is suitable for bucket rebuilding, ground-engaging-tool replacement and new bucket fabrication. Depending on the working conditions, the adapter may be used with compatible K70-series standard, rock chisel, tiger, twin-tiger, flare, penetration and loader tooth profiles.

Machine model alone should not be used to confirm compatibility. Before ordering, buyers should verify the existing adapter number, bucket-lip thickness, tooth pocket, fastener reference and mounting dimensions.

This product should be marketed as an aftermarket replacement unless genuine Komatsu or Hensley origin can be documented.
