C. Oil Orifice Retainer Ring Installation
(1) With the piston tube and fork removed from the cylinder, ascertain that all traces of the old
retainer ring are removed from the metering tube.
(2) A tool can be fabricated to simplify the installation of the new retainer ring. (Refer to 95-00-00.)

locating stud.
(4) Insert the tool into the cylinder, with the centering stud positioned into the hole in the base of
the metering tube.
(5) Hold the tool tightly against the metering tube and slide the sleeve of the tool towards the
metering tube. This will move the new retainer ring over the end of the metering tube and
position itself into the groove of the metering tube.

press fit with the grooves in the inner and outer races in the up position.
(9) Position washer and strut assembly retainer nut on top of the strut housing. Insert the strut
assembly up through the washer until it contacts the nut. Tighten the nut to a snug fit.
