Hello, great video! Got the same pressure washer and man those valves are hard to get out!! Gonna try your #4 easy out trick, seems to work quite well! One thing i noticed is that when you put your high pressure seals back in the opening/grove in the seal is supposed to go face down. That way when the machine is pumping water at high pressure it pushes out on each side of the seal in that groove. Im sure it will work the other way but I thought i should mention it to you as it might start to leak. You can check the exploded parts diagram and see for yourself. I pressure wash log homes and own a variety of commercial washers, this small one is just for around the house and washing cars.
If you look at the look at the brass pump head perpendicular to the front of the unit, it is very obvious where the long bolts go and where the short bolts go. Right top are the short bolts and left bottom are the long bolts. I replaced the seals on a similar pump and the metalic looking seal was somewhat difficult to replace. I put it in boiling water and then used my 90 degree pick to get it started. Then I used the blunt end of my pick to press it into place. Hope this helps someone.
Those keihin carburetors are actually the oem Honda carburetor. They are on all their engines from the GC/GX (horizontal shaft) and GCV/GXV (vertical shaft mower engines).
If you get no pressure and it sprays a stream of water without the pump engaging, check the filter first. It is located on the water intake. Mine was 1/2 inch deep plugged with calcium.
Jamin joes garage. It was a 54 with a smashed up door and a cheesy little amp lol Frank Zappa. Thanks for the video. I plan on buying one in a couple weeks and possibly putting a cat pump on
It was a cheapo $100 unit that I ordered on Amazon years ago. The heating element burned out pretty quickly, and the rocker switch on the back broke a few months ago, but with some re-wiring, it still works just fine.
As a best practice keep your fleshy bits out of all ultrasonic environments. The risk is not joint related. The risk is cavitation pulling gasses out of suspension potentially creating clots. Clots that can lead to pulmonary embolism, stroke, reduced flow to extremities. The risk is low, but easily avoidable. So avoid it. Ever see the bubbles forming on the surface of parts? Same thing internally.
@@JoesGarageProductionsLLC Pipe threads seal by deformation. The tape or any "sealant" is a lubricant making it easier to apply sufficient torque to deform the threads. I performed some studies in college. On a 1" pipe the input force is about 5x absent lubricant and grows exponentially as the diameter increases. The study included cutting the union laterally with a water jet and polishing the surface to accurately view the thread engagement and deformation or lack thereof. "Sealant" is the number one failure of high pressure hydraulic systems that have been serviced. Industry has for the most part abandoned pipe threads over o-ring boss. I enjoy a desk job at a large equipment manufacture.

I work on GX 390 engines all the time because of equipment customer owned 40 of them
Love the engine 😊😊

Didn’t he put the high pressure seals backwards? Does it matter at all??
Great video, as usual. You’re not afraid to jump into anything.

Yep, learned something new while making this video. I don't get to work on the small GX series very often.
Ive been watching a lot of pump repair videos. Ive only seen 2 using an ez-out for valve removal, you and one other!

I am not a huge fan of those filters. General Pump makes a much higher quality and capacity filter that is less prone to the problem you describe.
With obtaining a pressure washer in unknown condition, I would have also replaced the engine and pump oil as part of the overhaul.....

I actually ended up swapping this AAA pump out for the CAT 3DX shown in this video. Will be uploading the rebuild of pump shortly.
Opps, my bad, the top right are the long bolts and the left bottom are the short bolts.
You can use needle nose pliers to pull the old check valves out and to put them back in also.
Sometimes they work, sometimes not. Mine were really stuck in there.
Very smart mechanic on just about everything you do
Thank You for the information and videos 😊😊😊
Great video, same issue
Great informative video..
Great video. What brand and model is your ultrasonic cleaner ?
It was a cheapo $100 unit that I ordered on Amazon years ago. The heating element burned out pretty quickly, and the rocker switch on the back broke a few months ago, but with some re-wiring, it still works just fine.
All my check valves are good and still no pressure what’s the next step thanks for your video !!!!!
There could be a problem in the unloader but check the check valves very carefully.
Does parts work for DXPW61299. Thanks ahead
this vid its 1hr and 20 mins too long
I think carb is oem because it has a filter which aftermarket doesn’t
Yeah, that's a really good point. A lot of the aftermarket/clone carbs don't have the sediment bowl.
Can you tell me what brand ultrasonic parts cleaner you use. Thanks!
Harbor Freight
Where are you ordering your parts?
It depends. I order a lot of my commodity parts from Stens, but odd-ball stuff, I order from retailers the same as everyone else.
Where you buy the parts
There should be links in the description
Do you ever feel like going to the ER?
I was told not to put fingers in while ultra sonic was running ??
Is that true? I’m not talking a chance anyway.. lolol
I was wondering the same thing... Probably not a terribly good idea as it may cause cavitation in joints and thus joint damage.

Fixed for how much not $17 bucks pump how much 😂😂😂😂
tape is not a sealant. its is really a lube to help it get tight. look it up
Sorry, not sure what you're referring to. I used a thread sealant (Oatey Great White), no tape here.
@@JoesGarageProductionsLLC pipe tape. some people think the name means it makes a seal, but it really classifies as a thread lube not a sealer.
