fingering only when I use a 515 tip


Graco magnum lts17 or x17

I have been using this sprayer since 2008 without any problems. Always used the pump saver after each use, I only paint about 5 homes a year with it.

I assumed fingering was from using the original tip from 2008, so I bought a new 515 tip and cleaned all the filters. It still fingers when I spray. I can also hear the pump laboring harder than what I am used to.

When I change out the tip back to a 313- everything works fine. I am assuming I have a pressure problem.

QUESTIONS:
Could the pump be going bad?
Rebuild the pump or buy a new one?

It sounds like the packings are going out. Lot of times they get weak before they go out.

I agree, that it may be the packings, which can lose flexibility over time. This affects the pressure build up; a gauge on your output line will indicate if the pressure is not consistent. A .02 difference in the oriface size should not be much of a difference.

I agree on the packing as for rebuilding or replacing it has been my experience that with the smaller pumps it is best to replace. For what you paid for this pump it has paid for its self many times over. Now might be a good time to upgrade even if only a couple levels.
