Bushings are oversized precision bushings for damaged pump housings. The pump-housing bushing-bore ID will require machining. Bore pump housing to 2.0020” (50.85mm) plus zero/minus .0015” (0.040mm). Outside of pump and front seal bore are both concentric to original pump bushing bore so either can used for centering pump prior to machining. Original housing bore is 1.9693" (50.020mm).
