When i switch the titan ON the fan spins about a quarter turn and then just stop and does nothing. If I keep turning it off and on it will make the piston go down and up a little bit each time....not sure what it could be....any suggestions?
Your Transducer is shot the 440i has had this problem since inception. Now they are getting part made elsewhere. Your 440i has a four year warranty. it is covered the part if you dont have warranty cost 85.00 US. It is not a hard thing to replace on your own about 12 min. and your set.

If the motor fails to start look for a button (often red) on the motor. This is a reset button for the thermal overload protection most electrical motors of significant horsepower are equipped. Make sure the power is off, push the button to reset, then power on the motor. If the motor still does not start check to see that the mator's shaft turns freely. If not, the mator's armature is frozen due to corrosion or melt down. If the armature turns but the motor still isn't starting, another possibility is that the motor's brushes are too worn or have cracked or fallen apart due to age and/heat. Motor brushes are fairly cheap and normally easy to replace. If you're not a handyman consider taking the motor to an electric motor repair shop to check for continuity and estimate for repair. Hope this helps!
Check the brushes these motors for ever
You could also disconnect the pistion from the motor shaft the connecting rod to make sure the pistion is not the thing that is not moveing and binding the motor .
Most of the time problems come when people don't clean them correctly after use then store then for a few years .
Now I need my pump again except the old paint is now rock hard and nothing moves anymore the lines are cloged filters guns tips check valves .
All I know is my 660 titan witch is the same as the 440 except mine has flat valves instead if balls for check valves has been working great for the last 35 years but I clean it .
It is hard to follow your question....however; if the sprayer turns on and the paint fails to enter the nozzle, you may have a blockage. Take the spray nozzle apart and run hot water over it to clean it out. You may need a small brush or cu-tip to clean the inside of the barrel. Blow though it and see if air passes easily. reassemble and run as you normally do. Be certain the top is attached to the paint reserve tightly and securely. Any air leaks will prevent the sprayer from building up pressure within and thus no spay will be emitted.
When you switch it from prime to paint and it's still running: - If paint/water continues to come out of the prime tube, your prime valve isn't seating properly and needs to be replaced. - If you get a little pressure at the paint gun but it is surging, your packings, most likely the lower set, are damaged and letting most of the paint leak back past them. Packing/seal kits are available for your machine. Use all parts in the kit and grease/lubricate all of the parts well. Inspect the piston and cylinder for scoring or pitting that can damage new seals. They should be mirror smooth for proper operation and life of the seals.
Either your gun is dirty and the valve spring can't close the tip valve properly or the seat it pushes against is damaged. First try cleaning the gun very throughly. Take it apart and get everything out of the gun that doesn't belong there. If it still does the same thing you can buy a repair kits for the paint guns but they're usually expensive and you're almost always better off replacing the gun.
If an airless paint sprayer won't prime it's usually because one or both check balls are stuck. First try hitting the head where the pump is sharply with a hammer, hard enough to knock the balls loose but not so much that you do any damage to the pump. If that doesn't free them up you may have to take the pump apart and clean them and their seats. If an airless paint sprayer won't develop pressure, it's usually because the packing rnigs are damaged or collapsed. The only way to check this is to totally disassemble the pump and check them. Also look for any damage to the piston and cylinder. They must be very smooth and shiney, if they are scored they will eat up any new packing rings you put in.
