6. REMOVE THE VALVE SPOOL- In order to replace the O-Rings located on the Valve Spool take hold of the end of the Spool and pull it out. Be careful extracting the Spool as a spring will come out with it. Make sure not to loose this spring as it belongs in the hole at the end of the Spool. Replace the O-Rings and apply a thin coat of Lubriplate to the O-Rings
NOTE:
Follow Steps 8 through 16 to
replace the O-rings on the
Valve Liner. If they do not

Since there is interference between the O-rings on the Valve Liner and the inside diameter of the hole a fair amount of resistance will be encountered. Once the Liner has been pushed in far enough two or three internal threads will be visible. These threads will allow engagement of the Valve Retainer Nut which when screwed in, will align the Valve Liner and Spool to their proper depth.
