Accessory 400403377 (drawing number LW180K. 30A-2) is a right side dedicated bucket tooth in the bucket assembly of XCMG LW180K loader, which belongs to vulnerable and wear-resistant parts

Material and process: Generally made of low-alloy high-strength cast steel through heat treatment, the tooth tip may undergo tungsten carbide welding or special quenching treatment to significantly improve hardness and impact resistance.
Adaptation relationship: Dedicated to the specific arm configuration of LW180K series (suffix. 30A-2 represents a specific working device variant), cannot be interchanged with other models of teeth at will, and the hole spacing of the bucket bottom plate needs to be checked.
Functional characteristics: It mainly undertakes the pioneering role of breaking rocks and cutting materials, and its sharp geometric shape aims to reduce excavation resistance and protect the bucket bottom plate and blade from direct wear.
High wear condition: suitable for high abrasion environments such as mining sand and gravel, crushing concrete blocks, excavating frozen soil or mixtures containing gravel.
Asymmetric force operation: When working on a single-sided shovel or inclined ground, the right tooth bears greater lateral force and needs to have higher bending strength to prevent fracture.
Replacement timing: When the wear of the tooth tip exceeds one-third of the original length or cracks or root deformation occur, it must be replaced immediately, otherwise it will cause a decrease in the overall digging force of the bucket and accelerated damage to the blade plate.
