Spiral Retaining Ring Installation Tips All KB Pistons are supplied with spiral retaining rings. This retaining ring was specifically requested by Keith Black, himself, because it resists breakage and stays in place. KB Pistons are designed so the piston can be used as either a full floating pin or a pressed pin assembly.  To install the retainer, first stretch it to approximately 3/4" by grasping the two ends and stretching it. When used with a pressed pin application the lockrings must not be used! Place the end of the retaining ring in the retaining ring groove and, using a small screwdriver, press the retaining ring in place, moving around the pin hole in a circular pattern to spiral the complete retainer into place. REMOVAL OF THE RETAINING RING  This requires two screwdrivers. Secure the piston with the connecting rod and soft materials to prevent piston or rod damage. Pick the end of the retaining ring out of the groove with a small screwdriver, and with a second small screwdriver spiral the retaining ring clear of the pin hole. |
