摘要

A universal hammerless pin assembly for internally coupling pieces of heavy machinery includes a pin having a cylindrical shank, a head, and a shoulder disposed therebetween along an axis. A cap is moveable between a free condition off the pin and an assembled condition on the head of the pin. In the assembled condition of the cap, a washer is carried on both the pin and the cap. In the assembled condition of the cap, the cap moves between an uncompressed condition and a compressed condition binding the washer on both the pin and the cap. The washer defines an interference coupling the pieces of heavy machinery and preventing relative movement of the pieces.
