ABSTRACT:
A puller for spherical bushings comprises an inner puller body having a cylindrical outer surface so that it can be inserted into the bore of the bushing with a lip at one end for engaging behind the bushing. A wedge member actuated by an elongate bolt forces the lip outwardly into engagement. A screw threaded portion of the outer surface of the puller body carries a nut which can drive a sleeve shaped outer puller axially along the inner puller body to engage an outer member carrying the bushing. An installing tool is also provided including a cylindrical portion for insertion into the bore of a bushing and a shoulder at the end of that portion for engaging the end surface of the bushing so that hammer blows applied to one end of the tool force the bushing into place.
