Answer

For deep internal bores, manual installation is nearly impossible. A 'Sleeve and Plunger' tool is used. First, the spiral ring is compressed into a tapered sleeve. The sleeve's leading edge is sized to match the bore's internal diameter. A plunger then pushes the compressed ring through the sleeve until it reaches the groove. At this point, the ring's internal stored energy causes it to 'snap' open into the groove. For a 3-turn ring, the plunger face must be perfectly flat to avoid 'cocking' the turns. It is vital that the sleeve is hardened and polished to minimize friction; otherwise, the ring may 'galling' against the sleeve or the turns may overlap, causing the ring to jam before it reaches the groove.
