INSTALLATION of the retaining ring. 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 requires two screwdrivers. Secure the piston
with the connecting rod and soft materials so as to prevent piston or rod
damage. Pick the end of the retaining ring out of the groove with a small
screwdriver, with a second small screwdriver spiral the retaining ring clear of
the pin hole.
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. The 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
lock rings must not be used!
