Pin 1545279 works in bushings. When replacing it, always check the condition of the bushings and replace them if worn. Suitable retaining hardware (e.g., bolt through the flange) and shims to eliminate side play are also required.
Operating with a worn-out pin or bushings causes dangerous play in the digging assembly. This leads to imprecise bucket movements, jerking, and accelerated wear (ovalization) of the bores in the arm and bucket, generating high repair costs.
Pin 1545279 is the main connecting element of the rear backhoe attachment. It connects the bucket to the dipper arm and the bucket links. It transfers immense breakout forces during digging.
