Abstract
An earth engaging wear member is rearwardly telescoped onto a support member and is releasably retained thereon by specially designed connector apparatus extending through aligned connector openings in the wear and support members. The connector apparatus includes a spool member rearwardly bearing against the wear member, a shim member forwardly spaced apart from the spool member and having a sloping rear surface, and a wedge screw member interposed between the spool and shim members. The wedge screw member has a non-tapered body threadingly engaging the spool member side portion, and a non-threaded, radially sloped surface area rampingly engaging the sloped shim surface area. Threaded advancement of the wedge screw member rearwardly moves the wear member relative to the support member to tighten an operationally-created loosened interfit therebetween.
