Well I guess I will answer my own question. No you don't have to just replace the whole thing. Take the valve control plungers out of the valve body, take the clip off the bottom of the plunger. Remove the plunger seat, put the plunger rod in the vise and compress the spring seats together. Work the plunger rod in and out, take a wire wheel and clean up the burs on the plunger rod where the spring seat sits. Clean everything up and reassemble. Works good as new for now. Don't know how long it will last, but works for now!
