Abstract

An improved bearing or bushing body extraction from a stuffing box using jack screws is provided. The bearing or bushing seal body includes at least one jack screw on each half of a split body. The jack screw passes axially through the sidewall of the body to the inner flange of the stuffing box and turning the jack screw against the inner flange to lift the body from the stuffing box. A single inner threaded or double threaded insert with a reverse outer thread and standard inner thread is inserted into the bottom wall of the body so that the body may be installed flush against the inner flange. By turning the jack screw through the insert and against the flange, the seal body is pushed out rather than pulled.
