Abstract
Wear caps protect the wearable surfaces of an adapter for an earth working equipment. These wear caps are subjected to erosion and wear by contact with abrasive material, such as experienced in an excavating operation. The wear caps can be attached to upper and lower legs of the adapter and protect them from wear. Each wear cap is secured to a retention feature on an independent mounting structure. The independent mounting structures are aligned and staggered such that installation of a wear cap onto the rearward independent mounting structure is conducted first. The independent mounting structures on an upper leg may be situated one above the other.
