2. Install a new O-ring into the groove of the stem.
3. Install the roll pin into the end of the stem (if removed).
4. Install the inner spring onto the roll pin in the stem end with a
counterclockwise twisting motion. The spring is to be installed onto the
roll pin such that the first coil contacts the end of the stem.
5. Apply assembly grease to the stem, from the O-ring to the reduced
diameter end. Install the stem into the adapter, with the reduced diameter
end entering the adapter first. Adjust the position of the stem if necessary
to bring the helical slot into alignment with the dog-point setscrew hole.
6. Install the large diameter washer (used on some models) inside the
bore of the adapter and over the inner spring until it lays flat on the end
of the stem.
7. Install the small washer (used on some models) inside the piston. The
washer must lie flat at the bottom of the bore in the piston.
