I am trying to remove my GMaid windlas, got all the capsans off plus 1 c clip.6 nuts underneath. Tryed to tap out a bushing around main 1 1/2 in. shaft from above but gearbok did not move. now shaft will not turn. Galley Maid teck said to pound it out using a length of pipe but Im not sure what ring to pound on. Does anyone have any ideas? Stewart
