    Hey great video. I have a Graco 395. It primes ok and ready to spray. When I start spraying my pressure bleeds off. It wont cycle.

      This sounds just like what I've been through with my 395. I don't know where I discovered this but I removed smart control cover and on the inside right hand corner is plug which resembles a phone jack. I unplugged jack and waited a minute before plugging it back in. Bingo, ran fine. However it tends to be recurring and I have to unplug jack every once in a while to get the machine running again. I think the plug may actually come loose from being moved from shop to truck and up and down stairs on job sites. May help.

    Ive had a recurring problem with my 395 where it primes no problem but then after a few minutes pressure steadily drops off and then nothing at all. Trieed all remedies you recommended here but still nothing. Im not sure how i discovered my solution butt i removed smart control panel and on the inside-right, on the very edge is a plug which resembles a phone jack. Anyway, i unplugged the jack, waited a few minutes, then plugged it back in. Worked like a charm. However, like i said, it is recurring. So unplugging jack works. I tend to think plug may come loose from sprayer being moved around from shop to truck and so on. Have you ever come across this?

    How does a ball guide get damaged?

    • @Brian_the_repair_guy
      @Brian_the_repair_guy  2 ปีที่แล้ว +2

      There are typically 2 types of damage you will see in a ball guide.
      One is pressure cutting. This is damage to the smooth surface due to a failed seal. This allows the materials to seep past under pressure and it will eventually "errode" away the metal leaving pits and scratches.
      Two. What we have in this video is compression damage. Over time the constant pounding of the piston compressing the paint against the seat as well as the tightening of the inlet housing will eventually cause the guide to compress and flare like in the video. The guide is a softer metal than the rest of the fluid section.

    Hey Brian, I just got a 395 that primes and builds pressure but keeps creeping a little every 2-3 while a rest. At first I thought new packings needed but when opened it up found the cylinder has a couple scratches but no visible damage to the packings….question:
    I have seen a video where the guy uses 600 wet sanding to make the scratch surface softer and get a little bit of more life out of the cylinder, what’s your opinion about this? And finally….The sprayer is working besides the annoying constant creeping of the motor so is there any risk of damaging more parts by running it like this? Asking because everything else like piston etc look great.
    Thanks in advance Brian.

    • @Brian_the_repair_guy
      @Brian_the_repair_guy  2 ปีที่แล้ว +2

      Sanding the cylinder will make no difference in the end. By sanding it out, you do 2 things. First, you change the diameter, this means the cylinder is larger therefore the factory specs for the ratio of the cylinder and the packings are not as tight. This will allow more of a chance of high pressure leaks and will speed pressure cutting. The second thing, you will inevitably sand one section more than another, putting the cylinder in an oval shape. Again leading to pressure cutting and increase the creeping intervals you currently see.
      The cost of the cylinder is minimal along with a set of packings. I personally would never bother taking the time to perform the sanding because it will make zero difference and save you nothing.

      @@DownloaderVideo you cylinder is already beyond repair. Nothing to worry about there. The packings will wear faster now, just keep an eye on the pressure. As the packings wear, the pressure will be hard to maintain and the creep will be more frequent. If the packings wear too much, you could get pressure cutting on the piston. So just be aware, but other wise you should be good.

      My first though on the FFLP tips is to use the fine filters in the machine and the gun. This will catch far more trash. These are the blue filters from Graco. You may need to increase the pressure a bit. When the pressure is lowered, the machine can't push through some of the trash as easily. How old is your hose? Build up in the hose can cause excessive clogs as it breaks off.

    • @Brian_the_repair_guy
      @Brian_the_repair_guy  2 ปีที่แล้ว

      The part should be installed with a hammer to ensure tight compression. A wrench will not achieve the proper torque. Using a wrench will not usually remove the intake housing for the same reason when it was tightened properly.

    Hi Brian. I have a 495 ultra max 2. It will prime normal and pressure up but after about 10 minutes you can visibly see the lower end of pump loosen up and paint will start spraying everywhere as it try’s to keep pressure . If I tighten it back up it works for a few minutes then does it again. The entire unit is only 2 years old. I’ve changed the packings and replaced o rings. Any help would be awesome. I’ve asked long time painters and they have no idea.

    • @Brian_the_repair_guy
      @Brian_the_repair_guy  2 ปีที่แล้ว

      Make sure the inlet housing has clean threads. All the way down to the valve and guide. Same for the cylinder. Replace the lower O ring on the cylinder. When you tighten the inlet housing you MUST hit it with a hammer to ensure it is tight. Hit the tabs like it owes you money. About 3 swift times. If the housing continues to loosen, replace the full fluid section. It costs about $380.

      Graco has done something for the pickup tube housing to come loose the way it does. My o ring is fine, my threads are clean, I hit it with a hammer and it keeps leaking. I'm about done with Graco.

  • @williamwinsor7376
    @williamwinsor7376 2 ปีที่แล้ว +2

    I expected the wipe ring to be melted down around the piston. And I suspect the packings have to damaged somewhat and the last time I had to clean out the lower ball the owner thought it would be a great idea to do it every time until the seal failed on the cylinder and it leaked. I have a drawer of lower ball cages probably like you do. It’s hard to tell owners how to do maintenance without getting a blank look because they just want it to work! It’s hard to determine how far to go on every machine.

    • @Brian_the_repair_guy
      @Brian_the_repair_guy  2 ปีที่แล้ว +3

      True. Each machine is like a new adventure, even if they are repeat "offenders" or first timers. I try to teach them proper use and maintenance. They are painters not mechanics and that's about as far as it goes. Some try, but eventually get out of the proper practice.
      In the end, I do my job to make money. I also try to teach and I know that if they follow what I teach, it can mean less money for me. If they learn, I am happy to not see them as regularly. If they choose to ignore my words I am happy to take their money.
