The part was not replaceable through Graco, but I found what appears to be the equivalent o-ring spring shaft seal on McMaster-Carr, and for only 3 bucks!
Thanks for the video. I ordered the part and as you mentioned cost me $4 plus $10 shipping. I had the same issue and replaced the pump, which cost me about $150. I will fix it and have it as a backup replacement for next time, and yes, it is outrageous that GRACO can't sell that part separately.
@@melgueta1 It’s so silly I called them and when I told them it was ridiculous to not sell consumable parts they claimed it was not a consumable part when taken care of properly. When you buy a gasket or rebuild kit for just about anything else on the planet, what does it come with? Replacement seals. You bet your buns seals are consumables.
@@melgueta1 I only used the thing one more time since then and its still functional. The main thing is to use their blue fluid they want you to keep in the system while not in use. That will also keep things lubricated and moist.
The idiocy of these companies with not making parts available or economically viable is aggravating. I looked at Wagner's products and was not impressed with design flaws leading to issues with paint in motors. Thought I'd see if Graco would be worth the price jump but after watching your vid, I'm disappointed. I'd like to see these companies giving thought to doing better with what they produce. The era of high disposability of products and income is nigh. Good on you for finding a solution.
I have a similar issue and am about to buy the seal based on your recommendation. thankyou so much! could you give an update as to how the spray gun is holding up with the new part?
So far no issues, but only used it once since. The part i think is exactly the same in every way as the stock one. It looked and felt the exact same and the PN i chose I made sure was chemical rated for all the chemicals you put through paint and paint cleaning. I am hoping it will continue to last and will post an update in a while after more time and use.
The motor powers a pump and the oriface is a fixed size, controlled by the nozzle insert you choose… So, pressure is a function of motor speed and nozzle size. The switch varies motor speed.
@@ryan_layneThank you! So will it go down to zero rpm? (anther reviewer had said this adjustment did not actually change the motor rpm) Asking because I am looking for a metering pump for paint - to dispense material as a controlled rate - not spraying, not painting.
@@nobreighner Uh no, it has 2 speeds. 1 or 2. When you pull the trigger, it's on or off. Pretty sure it's just a 120v universal motor so you should be able to drive it with DC as well, and use any DC speed controller to control speed pretty precisely by varying voltage, providing the controller is rated for the voltage. That said, if you want a metering pump then you really have a lot of better options out there. There are all sorts of low voltage DC fluid pumps on amazon that only cost a few bucks, vs the hefty price Graco charges for the pump unit alone in these things.
@@ryan_layneThanks! Oh, you have the 2-speed. The problem is the material to meter is like a thick paint, and metering pumps that handle that are pricey. I have not been able to control the speed of several airless units with any kind of speed controller - otherwise they work great. Looking for an off-the-shelf product that will work for a particular DIY application.
@@nobreighner Have you tried hooking the motor directly up to a benchtop power supply and varying the input voltage? Universal motors should be just that easy to control. The caveat is they are pretty low torque at low RPM so they will stall out under pressure at low voltages. A stepper or a closed loop BLDC motor would be good candidates for low speed high torque control. All these things are pretty cheap and readily available parts, so maybe you can replace the motor of an airless sprayer with one of those if you have sprayers/pumps already.

@@ryan_layne By the way, how is the o-ring seal working so far, and any other recommendations other than putting some grease on the piston?

Thanks a lot bro for the help

Youre a saint, good on ya. Right to repair forizzle

Thank you so much for video! Please help me choose o-ring spring shaft seal. I can not find .( Same model)
The part number and website name is stated in the video
Does the variable speed actually adjust the rotation speed of the motor, or is it just a pressure adjustment? Thanks!
