2. Clean any dirt or corrosion from the beam, and file off any sharp edges.
3. Push the larger polyurethane part marked 5-305A into the beam from below.
4. From the top of the beam, place the smaller polyurethane part B, labelled 5-305B, onto the end of polyurethane part A.
5. Apply some of the supplied grease to the bore of the polyurethane parts and push the stainless steel sleeve into the bore of the bushes so it sits flush inside them. Ensure that the polyurethane part B is straight on top of part A.
