This happens to all of us at some point or another. It always the same responses. 1. It is not the fact that there may be a 1/4" hose instead of the larger 3/8" hose. Graco made these for many years w the 1/4" hose and they painted fine. The larger hose was beneficial but never was the cure for hourglassing unless the hose was plugged. If just switching to a larger hose was the cure all, then your saying that all Graco machines they built w a 1/4" hose are supposed to hourglass. 2. The paint you have always used is too thick? I've never seen that as the case. I have used solvent base paint at 10*F and it paints fine and it will be so thick you it will barely pour. Thinning the paint only bypasses the problem you have. 3. When you do some maintenance and end up with a new problem......guess what you have caused it or created it. Sometimes this new problem is because we have done something wrong or disturbed it which made this problem come now to the surface. Bottom line. It is a pump issue. Re-examine the pump that you just overhauled and all lines leading up to the pump. Never dismiss anything that Cormac tells you. He is probably the most knowledgeable on any Graco situation.

If you replaced the packing and the ball, did you replace the seat for the ball or turn it over. The seats are double sided for a new ball. As the ball wears, so does the seat, so either replace the seat as well or have it machined with a new face. This has never given me a line as bad as in the picture, but it can be one of the things that adds to the problem. If you did replace the ball and not the seat, it will eventually reseat but it will take a bit of time.

I considered it set itself. It went right again to doing what it was doing. Currently, I've modified the push providing, thouroughly cleansed whole program from mountain catcher to tip of weapons. Changed demand device. I'm at a reduction here. Changed shows, thinned shows.

It's just some of that nasty canned meat. If it turns into a troll Don will shoot it.
