Servicing waste gate valves ( Greay and black water valves)

I did mine as Bill described in his post. It took me a lot longer than 10 mins because there was not much play in the lines. Not wanting to do this job again. I installed grease fitting in the front of the valve face. When ever the handle gets hard to pull I give it a shot of grease usually once a year. The fittings are self tapping and thread easily into plastic.
