I see so many of these units in repair videos.that look like they have never been cleaned.. i just purchased my first ever graco 395 PC used. Build date of 2017 and it still looks new. Lots of good rebuild videos. Thx
Yes, many of these machines look rough. I like to point out, consider how much and how long they have been used and are continued to be used goes to show the durability of these machines.
Excellent video I appreciate your time I am a 42 year veteran of painting and I probably have 10 pumps that I have no idea how to repair but I am learning from you why do all of us painters want to argue with people trying to show them what to do I don't get it thank you for your information it was very very helpful
Don't argue, do your homework and do you- baggage is carrying lazy people..constantly learn and be better, for yourself and if you can help someone..ok..but do you, first.
Thanks Brian this was very helpful in the pump I have I got it for free from a professional painter and used it for 2 years on various jobs then it quite working so after seeing this mine looks even worse than the one you were working on so I'm just going to buy a new one By the way I'm not a professional painter but know alot about it I'm a handy man and remodeling needs person thanks again
Well, if your motor is running, I would really consider fixing the one you have. The cost of a new 695 is about $2500. You could fix yours foe considerably less of the board and motor are good. I rebuild them fairly often, and they are just like new and reliable.
I will do what I can on these. There market on these machines is limited. They are older, and not many guys use them, so I don't get them in the shop much. Subscribe and you will be notified when that video comes up. Thanks
I have a Graco 7900 I bought really cheap off of Craigslist it's the first sprayer I bought that I can't get the engine to turn what should be the first thing that I'm looking for. It had been sitting in somebody's garage for about 2 years so I thought maybe it was hydrolock so I pulled the spark plug and spray to PB blaster in it let it sit for a while and still can't get it to budge
Nice and detailed video, great content. I have the same machine, but after being idle for 2 years (and the guy that last used it, filled it partially with water) it won't such up the paint. Do you think it's rust at the primer valve that could be the issue? I unscrewed and checked both balls, everything is loose and fine.
The machine should prime regardless of the prime valve. If both balls are free, try putting oil in the lower inlet housing before you reassemble. Then give it a try. Let me know what you get.
@@Brian_the_repair_guy I already did that, but haven't disassembled more than up to the intake valve housing - Looks like I might have to upen up tho the piston and look through things there. Sucks, I had this problem before, but bashing the intake valve housing some times, to loose the ball, always fixed it.. Out of luck this time ;) Atleast the motor still runs!
Great information that you are sharing. If my Graco 490 has a slight hissing sound near packing does that mean I need new packings? Also it tends to keep running after I release the trigger. Thank you you in advance
If you have a hiss after the pump stops, the first thing I would check is the inlet valve. Pull the inlet housing. Remove the ball guide, ball and seat. There should be a white gasket under the seat. Remove this. Check the base where the seat and gasket sit. Ensure that the shoulder that holds the gasket and seat is smooth. Should be shiny, not dull or pitted. If it is, replace it and the gasket. Reassemble and check it out. If these look good, pull the piston and check the packings, upper and lower ball to ensure they are smooth. Replace any part not in good condition.
Hello. How much did you tighten the piston packings? It looks like you ran it in and it stopped on the mental landing. Can’t be any more Tight correct?
Hello...great vid... Do you know where I can find the specs on these pumps as far as torque specs and spec of how far fluid section is supposed threaded up into machine...sleeve id specs and such... Thank you in advance...
Good explanation for how to do this, but according to the instructions on the Graco repack kit, you have the wiper and the washer in reverse order. Do you ever see pump issues because of this?
@@jasoncox2606 yes, depending on the age of the manual, you may see it different. It makes no difference in the end. I have seen it both ways over the past 32 years and I have not seen any difference in wear
@Brian Shumack the repair guy I appreciate it. I do have another question though. I bought this new in 2007 and have never had any issues. I'm putting the pump back into the unit but I have a "C" shaped clip that goes somewhere on the outside on the upper portion. But I cannot remember where it came from and can't see where it would go to save my life.
@@jasoncox2606 I think you are reffering to the packing nut spacer. It goes on the packing nut. As you tighten the packing nut it prevents you from over tightening the upper packings.
Quick question Brian, I’m repacking a 1095 and according to the instructions on the back on the outlet valve the retaining ring goes first and then the plastic wiper washer but here you put wiper washer first and then retaining ring….does this vary depending on the machine….error on Graco instructions? Thanks in advance.
The order has changed over the years. Some manuals have it one way and later manuals have ot reversed. I honestly don't see a problem occurring either way. If you feel better with the instructions on the packings, then I would stick with that.
Do you repair pumps, I have a mark V with a pressure regulator problem and a few other pumps that could use a pros touch? There are no certified repair shops in my area. Thanks Steve
Not the first time I have heard this, and not the first time I have stated that the order has changed over the years. Depends on the manual you look at. In the end, makes no operational difference.
Hi Brian! Great video and explanation! However, I have the Graco 695 and bought the Repack kit with part number 248212 and the gaskets are super loose on the piston. Can you provide the correct part number for the repack kit for this sprayer? Thanks
What is the part number of your machine? It is located under the frame and is 6 digits. If you can not see it, tell me the full model you have. Such as Graco ultimate MX II 695. There are variations based on age
@@matheus147005 the repair kit is 244-194 or the updated kit would be 18B260. This is the kit for the 390 through the 595. Some of the parts you will not use.
@@Brian_the_repair_guy thank you so much! Just read the description for that repack kit and it’s for older units of ultra max 695. You’re a life saver.
Hi Brian, I have a male gland that is frozen to the rod and refusing to come off, I left it overnight in lacquer thinner, then tried gas and nothing…have you found something similar and any tips or tricks to get it out? Thanks in advance!
When the male gland is stuck on the piston I will usually put the piston in the jaws of a vice. I tighten it enough to where the piston is loose but the gland sits on the jaws. I put the outlet valve back on the piston about half tight. I then begin to tap down on the inlet to force the piston out of the gland. Place you hand under the piston in case in falls to prevent damage. If this is not clear, let me k ow. I will try to clarify the instructions.
Personally, I prefer the Graco 695. There isn't much difference in the performance and ability of each machine. The warranty is the same. The 840 has to wear on the cylinder, so that is something you don't have to replace, but the piston and packings typically wear faster than the Graco 695. Parts for the Graco are found in more places than Titan.
I can only do a video on the machines that come in to my shop. I use real world machines for my videos. If I get a Mark IV, I would be happy to do so. The 695 rebuild is very similar to the Mark IV rebuild. If you have questions, feel free to ask.
That sleeve was definitely wasted, but if the scratches are very fine, a Scotch Brite pad can take fine scratches out of the sleeve, you just don’t want to overdo it because it can oversized the sleeve for the piston.
If you use anything to remove the fine scratches, then you are removing the actual.metal, making the internal circumference larger. Not only that, but you are not able to do this in a uniform way. Making some areas much larger than others. Either way, the seal is not tight and will allow a pressure leak. This will expedite the wearing of the packings. So in a very very short time you will be right back in the shop, much sooner to spend more money on another set of packings as well as the sleeve you were going to replace any way. Everyone is free to perform whatever "repair" on their machine that they like, their choice. My purpose on the video is to show the best possible way to repair the machine that will not cost you more money sooner, rather than later.
@@Brian_the_repair_guy It was in some ways, because I have a 490 it wasn’t exact but the idea is the same. As you know mine doesn’t have the same type of sleeve as the 695. I was actually in my buddies auto shop doing the repacking and showed him the inside of the sleeve and he was the one who recommended I use scotch brite otherwise I wouldn’t have even considered it, they take 1000’s of inches off cylinder sleeves in vehicles often. I have a few set of seals from years past, if I have to repack I can but I’m interested that you pointed it out because you bring up valid points. My friend is a wiz mechanic and he doesn’t think it will make an impact as he inspected it himself but I’ve learned a lot on my machine so that’s the ultimate goal for me. I’ve replaced the transducer and prime valve over the years but never did a repack, it’s working great so far!
The sleeve of the 650? You can clamp the lower end of the sleeve in a vise and put a wrench on the cylinder and twist it back and forth to loosen the sleeve.
@@centralfloridasprayfoam4870 if you go to Gracos website and pull up Graco manual 33465D, which is a repair manual for sleeves pumps, you will see on page 10, line 8 "gently guide displacement rod up through throat packings. TAP bottom of piston valve as necessary with a LEATHER OR PLASTIC HAMMER" so of you have an issue with the directions from Graco, contact Graco and share your concerns. I stand by my statement that you did it wrong.
@@Brian_the_repair_guy I’m glad your on the hot on the case of the displacement rod packings, detective. You seem hell bent on stating that I’m wrong repeatedly. I appreciate your concern. Speaking of wrong then, I see that you put the wiper gasket, 118503, directly on the valve 287877, and then the back up washer 16C997 on the wiper. I think the manual shows the back up washer in first. But I could be wrong. And if I am, you’ll surely tell me!
yes go to certified shop so they can perform a very detailed wallet cleaning, and then buy a new one. just go on Amazon or ebay and buy the same identical parts for 25% of what they charge, don't worry they are all made in china.the same factory that makes original will sell the same product as generic but way cheaper. Dude just show the how to video and stop trying to clean wallets too
You have the option to do as you wish, it is your machine. You also have the right to use whatever parts YOU choose to use on your machine. If you don't like the message, then walk away. No one, and I mean no one wants to hear your diatribe. I have seen first hand how inferior parts damage your machine. I have seen guys loose fingers because they used inferior parts. All parts are not made in China. Graco has an in house factory where hard parts are manufactured. You are more than welcome to come visit. A certified shop does not just look at the problem at hand, they inspect other possible issues to insure safety and proper function. If YOUR wallet can not handle proper maintenance and repair, then YOU may want to reevaluate your career choice.
@@Brian_the_repair_guy REALLY ????? Then how come I went to the local Graco authorized center which is inside the big PPG store here in Columbus OH and I wanted to buy a transducer for my 795, and lo and behold said right there on the graco box "country of origin : CHINA". Transducer which if it goes bad you are shit out of luck on the job. Come on Brian, please give us a list with what parts they make in USA????
@@FreeYourBrains reading comprehension is fundamental. I did not state ALL parts are made at Graco. You scenario is convoluted. Based on your scenerio, yes that part is made in China by Graco specifications, not Made in China by a stolen design with little to no quality control. Again, if you cannot afford to properly and safely maintain your equipment, I suggest you choose another career path. Good luck, be safe.
@@FreeYourBrains I apologize, you requested a list of parts that are made in the US. In regards to the electric units 390 up to the 1595, all pistons, inlet housings, outlet housings, sleeves, cylinders, pickups, filters, fasteners, frames, shroud, motor, gearbox... wait. This list is lengthy. I will list the items NOT made in the USA. wheels, some hoses, electronics. Most electronics (specifically the boards) are made in Isreal. Some electronics (secondary items) like the transducer and potentiometer are made in China by Graco specifications and QC. Not made in China with pirated technology illegally. If you have a issue with a part, Graco has a warranty on their parts. The Chinese knock offs do not. As with any machine, it only takes one part to put you down. No matter if it is packings, piston, electronics or what have you. We all know this. This is exactly why I make this videos and repeatedly state that in the videos. These videos are to help people like you that are in a bind and need to get the job done and paid. If you can't appreciate that, then I am sorry. I also state repeatedly that a certified shop is recommended when you have completed the job, because a certified repairman knows what to look for to prevent other problems and also what possibly lead to the problem you have. Your above scenario does not justify NOT taking your machine to a certified shop. In fact, it reinforces the idea of a certified shop. If the part was replaced from an internet purchase and it fails, you are out of luck. If you take it to a certified shop, you are warranted if it fails. That you for that fine example of how not to do it.
