Step 4  Remove the O-Ring from the Piston Groove. Install new O-Ring from kit. 
Step 5  Remove the Quad Ring from the ID of the Upper Housing. A small pick can be used to expose a 
small cross section of the seal to grab with your fingers. Do not cut or pierce the quad ring. Do not gouge 
the seal groove or housing. Remove the large O-Ring from the bottom of the Upper Housing.

Step 6  Place the Upper Housing and hose assembly up-side down on a piece of 1”x 2” wood block or 
similar material. Using a small diameter ‘drift’ or punch (1/8” or smaller), drive the Spring Pins through 
the Upper Housing from the bottom.  See Figure 4. The swivel fittings and hose will pull out of the Upper 
Housing. A small pick can be used to remove the small quad ring fitting seal from the housing. Repeat for 
second hose/fitting assembly. 
Step 7  Remove metal clad oil seal from center of Lower Housing. Note location of seal depth, some are 
all the way down to the step in the housing, some are 1/16”down and some flush with the top of the bore. 
Make a note for you to reference when reinstalling the seal. You can use a socket with a 1-3/4” OD to 
drive the seal out of the housing from the upper side. Gently tap the seal out. Remove Quad seal from OD 
of Lower Housing.
