1200XS40 / K120040 Weld-On Center Adapter for 2-Inch Bucket Lip

The 1200XS40 / K120040 weld-on bucket adapter provides a replacement mounting interface for compatible XS40 and KMAX 40-series bucket teeth.

Designed as a center adapter with a Type 1 leg configuration, it is installed directly onto a nominal 2-inch bucket lip. Once correctly welded and fitted with the matching tooth and retainer, the adapter transfers digging forces from the replaceable tooth to the bucket structure.

This adapter is intended for bucket repair, GET system replacement and new bucket fabrication. Its verified reference dimensions make it suitable for buyers seeking a replacement for Hensley-style 1200XS40 or Komatsu-style K120040 applications.

Because bucket designs and previous repairs may vary, customers should confirm the lip thickness, adapter dimensions, tooth reference and locking system before ordering. Machine model alone should not be used as the final fitment criterion.
