120XS145CC XS145 T-Corner Bucket Adapter for Komatsu PC2000

Full Description

The 120XS145CC is a large weld-on T-corner bucket adapter referenced for the Hensley XS145 ground engaging tool system. Available Komatsu and Hensley-related documentation associates the XS145 system with selected Komatsu PC2000 mining excavator bucket configurations. The adapter is installed at the outer corner of the bucket lip, where it forms the structural connection between the bucket and a compatible replaceable tooth.

Unlike a bucket tooth, the 120XS145CC is intended to remain attached to the bucket lip while the fitted tooth serves as the replaceable working component. Its front section forms the adapter nose that enters the pocket of a matching XS145 tooth. The wide rear body provides the interface for welding the adapter to the corner area of the bucket lip. Installation position, fit-up and welding requirements must be determined from the actual bucket configuration and the applicable repair or fabrication procedure.

The supplied photograph shows one yellow-painted corner adapter from the side. The part has a large rear mounting body, a tapered adapter nose, raised longitudinal reinforcement and two raised eye-shaped bosses on the upper surface. The marking 120XS145CC is visible on the main body. No separate tooth, locking pin, wear cap or installation hardware can be confirmed from the photograph.

Komatsu documentation identifies the PC2000 with the XS145 tooth system and lists 21T-70-34610 as the corner-adapter number. This number may be used as a compatibility reference for 120XS145CC, subject to verification. Bucket designs can vary according to capacity, serial number, manufacturer and previous rebuilding work, so the machine model alone is not sufficient for final selection.

Published sources also differ on applicable lip thickness and finished weight. These figures should not replace actual measurement and weighing of the supplied product. Buyers should provide the complete machine model and serial number, bucket part or assembly number, bucket capacity, lip thickness, lip profile, existing adapter marking and photographs of the bucket corner.

Material grade, hardness, manufacturing process, heat treatment, inspection scope, included components, packaging and delivery terms should be confirmed in the quotation. This product is intended for distributors, mining companies, contractors, bucket manufacturers and heavy-equipment repair businesses sourcing aftermarket GET components for large mining excavators.
