RADIAL FIT COUPLING BOLTS - INSTALLATION AND REMOVAL

The principle of the radial fit coupling bolt features the combination of a taper bodied bolt and a matching taper bored sleeve.

During installation, the bolt is positioned in the hole in a clearance condition. Using Pilgrim hydraulic tools, the sleeve is expanded by drawing the bolt through the sleeve to accurately align the coupling and provide a true interference fit. The nuts are fitted and then the bolt is hydraulically tensioned.

For removal, the bolt and sleeve are separated using either the oil injection method or the removal bridge. The sleeve reduces in diameter to its original size leaving the bolt assembly free to slide out of the coupling hole in a clearance condition.
