ABSTRACT:
An adjustable bushing to accommodate a leader pin of a plastic mold. The adjustable bushing comprises a cylindrical body having a liner installed therewithin. The liner is smaller in outer diameter than the inner diameter of the body creating a gap between the liner and the body so that the liner can shift relative to the body when engaging a leader pin. The liner is held in place against an extending internal ledge of the body by a removable cap. In one form of the invention, compressible O-rings about the liner maintain the liner in a centered orientation in the body. In another form of the invention, a resilient member is employed to axially bias the liner to retain it in place.
