Prince Selector Valve issue??

The spool seals on a manual selector valve can become dry and make the spool hard to move. Before you take anything apart, spray both exposed ends of the spool with your favorite aerosol penetrant and shift the valve several times.

It is a Prince #9-6134 valve. I removed the snap ring and had to drive the stem out with a wooden rod. after getting it out i noticed scarring on the housing from what appeared to be shavings from a burr left inside the bore at one of the cavities, shaft was smooth as a mirror. I removed the seals,used my wheel cylinder hone to remove the small scars, reinstalled the seals and it now moves with two fingers, smooth as silk and so far no leaks.
