Repairing a Graco Paint Sprayer

- My 5 year old paint gun decided to break on me, and instead of buying a new one, I decided to try my luck and crack it open and see if I could fix it. Here are the links to the parts I used:

I love that you fast forward but still show you performing the step/action! So many videos I find either waste so much time showing basically 1 simple, but painstaking thing, or worse assume every viewer must know how to perform certain aspects and gloss over or omit them completely! I didn't find exactly the info I am looking for, but still felt my time wasn't wasted. Thanks!
It is a good testimonial that it took 5y to break. The trend I have noticed is if you buy a replacement, the expected life is shorter. Excellent video, thank you for sharing.
Thank you very much. Precise and to the point!
I think AvE did a video on a similar unit, with a leaky pump that he rebuilt. If you've never come across his channel before I highly recommend! He does a lot of tool teardowns that are very informative, and entertaining... us Canucks don't get much sun, does funny things to the sense of humour I guess 😂 I can't tell ya how many times I've fixed mine or family's home appliances with nothing more than a simple blown fuse.
I'll check it out, thanks for the info!
Great video, stuck in Hawaii no parts available. 🤙
Good Stuff, Thank you!
My x5 the other day made a grinding noise I never heard and then a bunch of tiny ball bearings fell out of the bottom. I'm guessing that bearing seal wen out. I'm wondering if it's dill coming on and the motor is trying to run should I just get the bearing. What do you think?
Love the video, We have 4-5 of these same sprayers in my friends shop. And your video has been invaluable in repairing them.. Really looking forward to seeing the video on rebuilding "the pump", it that becomes available? Thank you very much.
I looked into rebuilding that pump but a replacement cost more than replacing the entire sprayer. I now use model# 257025 and am better about using pump armor after every use and I love it. Glad the video helped keep your going!

@@AustinCoulson Thank you so much. I know The pumps aren't a rebuildable item. But I did notice there is a sleeve inside the bore where the piston moves. We will be using a borescope to go into the piston bore to get a closer look down inside? Also on my units I use a 50/50 mixture of mineral spirits and motor oil or hydraulic fluid to to store the sprayers. Great talking! THX.
@@VintageJunker if you find a way to rebuild the pump you should make a video and post to TH-cam. If you do let me know and I'll link it to my video
Yes Sir, I will share what we find with you, gladly!
Thank you very much 🙏❤️🙏🙏
I wonder if you can help. I took mine out of storage and it won’t draw fluid to prime. But if I fill the inlet hose it will pump through. Is the pump dead or something not cleaned enough
Thank you very much
thanks great video - in teresting it has a 250 V 10 A fuse - even though it is being used in the USA with 110V? does that mean the motor can be used with 240V safely over here? Im having a problem with the valve assembly - the motor works but there is no suction at all from the pick up tube even using the prime setting and the overflow tube? can anyone help me? thanks
Hi I have a graco x5 turns on but won't spray anything. I push the ball in n they move but nit sure what to do
Any update on fixing the leak. I have a project sprayer with a bad leak and was wondering if it would be cheap enough to fix and keep
If I remember right, the leak was on the pump module a new module cost more than a new paint sprayer so I gave this sprayer to a buddy of mine and bought a new one about 6 months after making this video. He does a lot less painting than I do so it still works, but still leaks.
Best video ever ..thank you..
How much you want to make a replacement fuse for me....thank you..
I like this video, could you help me with the diagram of the electrical board of magnum x7
thank you my machine has same issue today
I’m fairly certain I have the exact same problem. Is the bearing supposed to be able to spin if it is functioning normally? Mine does not move. I replaced the fuse and the pump turned on only for it to blow another fuse within two seconds.
yes it should spin freely. Sounds like you have the same problem I did
What is the function of the bearing? I'm asking because my pump works fine but it has a leak exactly were the bearing is. Do you think the leak would get fixed if I replace the bearing?
I had a similar leak, which is what caused the bearing to fail I think, and found that the pump is non serviceable on this model and replacement costs more than a new unit. I used it with the leak until it got worse, then got a new unit.
@@AustinCoulson thanks for letting me know. I had bought 3 of them for $50 for all 3. The guy that sold it them said they didn't work but they did, They were not running because they had dry paint from not being cleaned. I took them apart, clean them, I practically made them look brand new but one of them does have a leak and didn't know how to fix that. I sold two of them them for $150 each. At least I got back my money and more. Thanks again for letting me know.
Great vid. Hey what model is that sprayer? I’ve got a magnum x7 and graco had told me they aren’t rebuildable. I just acquired an older magnum XR9 that needs some work but from everything I’ve seen the xr9 is a rebuildable unit so that’s why I agreed to take it.
Here is the new version: amzn.to/3sp9VSO
The one in the video is a 257025 and I don't think they make it anymore. I was told this gun wasn't rebuildable either but everything except the pump can be rebuilt and the pump costs more on its own than the entire setup.
@@AustinCoulson okay it’s the x5 that is basically what you’ve got. I’ve got an x7 that I bought new about two years ago and I worry that I’m gonna wear it out. I have a handyman business and I don’t use it every day but I do use it kind of a lot. I think I heard the pump in the x5 and x7 can’t just be rebuilt. I heard you have to replace the whole pump and manifold which i guess is kind of expensive, almost as much as a brand new unit.
I’m working on a graco xr9 that I got for free, and the reason I accepted it was because all the parts are rebuildable. I just ordered a new piston and cylinder for it and I’ve been trying to find a video of how to replace the little pump. I just replaced the pressure knob which was over a hundred dollars but i still think this xr9 is worth putting some money into and rebuilding solely because it can be rebuilt and the parts are available.
I was hoping you had some pump replacement suggestions??
Anywhooo thanks for sharing your work.
@@wyattsdad8561 I actually don't know a ton about paint sprayers, I was just tinkering with my old one and wanted to share a video to maybe save someone else's pump from the dump. I would just Google around for a PDF that shows how they are put together and go from there
@@wyattsdad8561 You can rebuild those pump, all the parts on the pump comes off and on. Just have to be able to get the parts for it. Anyone can rebuild those sprayers easy, diagnose it easy.... not difficult once you've taken it apart and assembled once. But idk those sprayers quality just isn't there anymore, material, and being rushed produce.
@@dogmanboss7638 yeah you’re totally right. I ended up rebuilding mine. I call it the chupa cabre (the blood sucker) because it ended up costing me more than I was expecting to spend because I cracked the manifold while replacing the spray prime valve. Haha it was my own fault for over tightening it. But now it’s a dream machine. New piston, manifold, all new valves etc.. it great tho.
That's awesome, you saved yourself a few hundred bucks, but how long did that take you?
The bearing was about 30 min with disassembly, the fuse with soldering and reassembly was probably an hour. Filming probably added an hour or two and editing another hour or so. Probably not worth it considering the pump will still need work at some point and the gun is actually passed its rated life by about 50% already, but I did learn a little bit, so there is value there.
@@AustinCoulson I'm sure the bearing you used was better then factory, and you made the fuse user serviceable as well. So if you look at it from that perspective, if it happens again it'll go much quicker.
Great video, Tks.
Do you know if the bearing it’s the same for x5 magnum?
I am not sure
My graco sprayer tends to get really warm then stops working… I have to wait until it cools down to use it again. Any advice?
sounds like the bearing is overheating and seizing, then cooling down and releasing. But that is just a guess
Once the little piston wears you have to replace the whole thing. Not worth it on those because it’s just a different style of diaphragm pump the way it works because something else always goes out on them.they really are throwaway pumps but graco has gone to that style to satisfy homeowner cheap uses. I think they fill a niche. I repair the more durable types. I always have pumps made from spare parts laying around. Diamond dust can refresh carbide seats. Stay under 20 microns.
Good to know. Since this is such a cheap unit, I am not surprised about the piston wear causing this to become a throwaway pump. It's way past its life expectancy already
Hi I have a krause and becker and I'm not getting any power to the motor any suggestions
I only know about Graco sprayers, sorry
Built in obsolescence? One would expect a bearing to last longer. But what do I know.
That poor bearing lives in a tough environment, where it turns on and off constantly for maybe an hour or two then sits for long stretches. I think when the pump seal started to leak, the inside of the machine got humid from the water in the paint and it rusted while in storage.
What is speed of motor (rpm) please
That little pump under the gears, i have paint leaking out if that when i try to spray, or prime please healo 😭
As far as I know, that pump is non repairable and would need to be replaced and the replacement cost is more than a new sprayer from what I could find.
How do you get the legs off thanks
I think they just had phillips screws on the inside
Excuse me where i can get the bearing
amzn.to/3UvNI29
My bearing is broken , inner part of bearing is still on shaft, how can i remove this
Bearing puller or dremel
Thank you very much👍
Me gusta ewte video me podras ayudar con el diagrama del tablero electrico de magnum x7
👍👍😊👍👍
I got same problem but my fuse is good
Amigo tengo 1 problema
How to repair your pump
From a paint sprayer technician this graco x5 x7 or Lts ain’t worth to fix em
I agree. It's only worth fixing if you gotta get it up and running in a pinch.
