- I borrowed a pressure washer and the first time I used it the pump exploded. Being the nice guy I am, I decided to replace it before I gave it back.
Buy the same pump here. amzn.to/2xJqKOW
Buy same oil here. amzn.to/2wZke2p
Before running the pump I changed out the garbage Chinese oil that comes in it.

All this has done is proved to myself what I already knew about Axial Pumps, and that is that they are the bane of my existence.
My pressure washer pump blew up recently. I feel comfortable replacing it now. Thank you!
That’s the way to fix it not only replace parts, I did found many videos just replacing parts, I did that to mine, I never opened worked in one of those before. Nice job
I would never remember the order of parts going back in! Great video!
Great video. I use 30W non detergent oil in them
I had the same pump break. The bolts brok and the pump opened up and dumped oil. Everything was okay so I got some replacement bolts and added Briggs and Stratton synthetic pump oil. The new bolts heads shear off so the bolt shaft and the housing was damaged. I have pictures if you want to see.
Awesome detailed video of a pump that I just ordered. Thanks for giving some important tips and instructions. Very cool to see you disassemble the unit.
Thanks again 👍😁
Watched both videos. The difference in the oil was amazing. What do they use? Vegetable oil? In this video you can barely see the washer plate, but in Part 2 the new Mobil gear oil you can see into quite well.
Thanks!
Good info, I like your work bench, kudos to the wife, my wife would not let me use the washer as a bench.
To be fair, it was the old broken dryer that was waiting to be scrapped.
I just got mine wondering how to get the key out of the slot to get the pump off when I came across this video, thanks for the info, when I find a way to bet it off i will definitely change the fluid
Hey I commented below but I also wanted to comment... You borrowed a pressure washer.... Looks like you borrowed a CLOTHES washer too! 🙂
My pump's seal shat itself.....
After years of 150 bar constantly acting upon it, it finally said, ight, imma blow myself up....
I trash-picked a Husky HU80709 because it looked great and the neighbor said the engine ran, but that the pump was burned out- whatever that was supposed to mean. Was it ever! The pump was filled with black water and the bearings were torn up and rolling around loose. The bearing plates were gouged. One was cracked through. Even the “cup” body was tore up on the inside. But, thanks to your video, I think I’ll just spend the $60 for a pump and change the oil right away.
Glad it helped.
You put the cam plate on upside down from when you pulled it out.
Recommended oil is 10W-40, not gear oil. Gear oil creates too much heat.
mine says to use 85w90 on it.
Great video, thank you. I just received one of these pumps from Amazon and it appears to be leaking oil. Rather than sending it back I think I will rework it as you did and upgrade the oil. It likely has a pinch in the housing o-ring. I ordered it as a spare for my powerwasher since I know this is the weak link. Ultimately I will need to replace it, but your video might make it last a lot longer than it would otherwise. Thanks again.
Ed,
Glad it helped.
Bassntruck would it be possible to drill and tap a drain bolt in the side instead of tearing apart ?
KingQuad Bott Sorry for the late reply. Yes you can put a drain in it. The old one had one.
Nice dryer, I mean work bench.
Mike Spain I know, right. Nothing says class like a broken dryer work bench.
Great video, where I can find the ball bearing
Looks like a lot of work.
good idea changing the oil out!
Good video
Where can you find the little metal washers/seals that sit just on top, well technically bottom, of the housing. I can find the o rings in kits but the only way I can find the metal washer/seals is to buy a complete pump. Mine leaks water and I found that one of thise washers had been damaged and corroded, actually split all the way around and there was water inside the housing. HELP!!
Great video how much oil do you put in. I'm changing the oil on my Chinese horizontal pump it has a oil breather so I drained the oil out then used normal oil to clean the rest out mine is longer that that, it's the parkside petrol jet wash 180 bar and 6.5hp
I put back in what I took out. I really did not measure it. If it is the same pump as mine I would guess it held about a cup of oil. You could measure what came out and add a small amount more. Hope that helps.
Fill it up until you have an 1/8" to reach the top.
The oil at the bottom where the red seal leaks can I just order those seal, and where?
Basically, those are Chinese aerospace grade metals you're dealing with.
If the Chinese build missiles like they make everything else.....we have nothing to worry about....having said that I suppose as long as it does it’s job once......ok stay worried!
Do you know we're I could get replacement springs for the plungers mine snapped ?
I just got a new washer and it unfortunately has a Chinese axial pump. I will follow your advice and clean it out. Is it worth putting drain and fill plugs in the casing? Now I know what to expect inside. Thanks.
If you plan on changing the fluid often the the plugs would not hurt. Not that it is hard to pull apart.
Great video. Thank you!
I have a Ryobi pressure washer with this same type of pump it seps oil on Amazon what modlevwas it, and should I change the oil before I install it?
When do you add the oil back in after you put it all back together?? Where do you put it back in at??
I put the oil back in before I put it back together.
...and your workshop table is your dryer...?? You gotta be good... or your wife is away on holidays.. Lol.
It was the old dryer that had worn parts that was not worth fixing. It just so happen to be sitting the the garage at the time.
Hey...ive got a video on my page of some metallic silver liquid coming out of the (pump vent, i think ??)...i cant find anything about it on the web...any ideas ?? Its a ryobi ry80030 with Subaru ex21 engine...let me know what you think...there's 2 videos
Hey man, followed your vid and really appreciate the help! However, I replaced the pump and still have the same problem..no pressure! Hose and wand seem to be clear of obstruction...any ideas???!
Sounds like an issue with the unloader and being stuck in the "open" position, therefor making no pressure. That assumes you just get standard water feed pressure out of the wand. And that the insides of your pump are all in good order while put pack together correctly. I also take it you have no water seeping into your pump oil.
Edit: You replaced the whole pump and still get the same issue with a new pump? If that is the case it still could be a stuck unloader (odd) but are you sure the shafts are fitting together and the key is installed? If the key is missing or too small and slides down it will make no pressure as it is not spinning.
(feeling like an idiot)) where should the "key" be located? I had no issue sliding the new pump onto the shaft, but never noticed a "key". perhaps that is my issue.
terrell knight You will see a slot machined into the shaft on the motor and in the pump. It should be a 1/4" key. This is what makes the pump grab the motors shaft and spin. The key is just a piece of metal 1/4" x 1/4" and is likely about an inch in length. It either falls out when the pump is removed or is rusted in place making the pump hard to remove.
thanks man, I'll look into it as soon I get chance. I'll let ya know how it goes. :-)
Got er done, man! Found the key still lodged in the old pump. Pried it out, popped it in the new one, runs like a champ now. Thanks a bunch man!
Should have non detergent 30w
If the old unit only needed need bolts and a seal, just replace the bolts and seal. Remove the old sheared bolt by mig welding a nut to what remains sticking up and remove with a wrench. Ez.
How much oil goes in that pump, ?
I got a pressure washer that's running all the time, the pump won't disengage.... is the pump bad?
Maybe, could be a stuck unloader valve.
No need using that clamp bass!
I didn't want to strip out the threads in the housing. Or get popped in the face if it exploded.
What do you typically see go wrong with those axial cam pumps when they stop producing pressure?
If we are talking to the point they are not worth trying to repair. Seals, physical wear, unloader valve, other large catastrophic failure. That is what I have seen.
Bassntruck thanks!! I’m just gonna order a new one. Appreciate the reply!
That is suppose to be sae75w90
What oil did you use I've been told 30w non detergent, but I've also heard 50w gearbox oil
Rocky fish There is a link to the oil I used in the description. Pump is still working fine.
Use a lighter oil detergent or not. Add some hyper lube too, won't have to change as often. Autozone
hey man i changed the pump oil and put it take together and check to see if it worked still and water started leaking bad by the bolts to remove the oil cap any reasons why ?
I have seen some older pumps once they have been taken apart the plunger seals no longer hold the water pressure. Is the oil mixing with the water?
No its not
Which bolts are you talking about exactly? Where in the video do I remove them?
The ones u had to put a c clamp on so it wouldnt pop open
So around the 4:45. Then you likely have weak axial cam seals. This is somewhat common on older pumps once you take them apart. That or you might have damaged one or more when pulling the pump apart or putting it back together. I like to put a little oil on them to help it go together. If you can find the seals you can replace them. Might just have to measure the seals to order new ones.
Super touch 10w30 can you use it in a pressure washer pump
If that is all you have, you could put it in there. I would strongly recommend a real synthetic gear oil though. The motor oil will not las as long and the detergents in the oil might not be helpful.
Nooooo! Use ND SAE 30.
What oil do you recommend, I got sae 30w non detergent, but I was told that 50w moped/motorbike gear oil is good too,
Rocky fish Some recommend non detergent 30 weight. I use gear oil. Link is in the description of what I used. Thanks
Bassntruck some gear oil have detergent in
After doing some research. ND SAE 30 is the best.
bro my unloader valve is STUCK corroded in the pump body of a 1 year old Honda GCV160/Ryobi 2300 psi unit; any tips to get it out so I can service the faulty/stuck valve itself???
All I can say is try to work it loose. If it is that bad you might just be replacing the pump.
Had the same issue with my GCV190. I took the nut and spring off, then put a socket big enough to allow the valve to fit through. Attached the nut on the end and hand tightened it with another socket. Came off with ease. No need to attach socket wrench.
sO YOU'ER USING YOUR washer or dryer for a table Hmmm???
It was an old broken machine sitting in the garage that was waiting to be hauled off.
If I'm gonna let people borrow my tools, they have to be able to fix them if they break.
Where is part 2.
Right above part one on my video log when sorted by date. Or right here. ruclips.net/video/EE0P0_kxjNg/видео.html

Can’t see what your doing
Got This Pump From Amazon But The Horizontal Pump, Installed It And Noticed That It Slightly Started Leaking Oil From The Seal That Seals The Shaft. Any Idea What’s Wrong? Maybe The Seals Not Seated Properly? Thanks In Advance.
Make sure where it is leaking from. I have seen a leak from the engine look like the pump. If you are sure it is the pump, then the seal is just bad. Could have been damaged in production or could be defective. There is a small chance it could stop leaking on its own (before it runs out of oil). You could return it or just get another seal. There will be aa number of number on the face of the seal. They are the measurements of the seal, just find a match.
Bassntruck I’m 100% Sure It’s Coming From The Pump, So Best Bet Is To Replace The Seal?
Is it leaking where the shaft from the motor goes into the pump, from the halves of the pump, or from the bottom of the pump? The case halves are just an o ring. if it is from where the shaft is then a better seal will fix it. Or return it for another. I looked at the video and could not tell if the numbers are on the side of the seal. If the current seal has no numbers then you can just measure it and find what you need. Just need the OD, ID, and width to find a new seal.
Bassntruck I Can See Oil Leaking From The Orange/Red Seal That Sits In The Case Of The Pump Where The Motor Shaft Goes.
Then just measure the ID, OD, and width of the current seal and look one up with those numbers. Pop the old one out and tap new one evenly down until seated. Using a large socket or something round if you do not have a seal driver. Put a little oil on the inner part of the seal before you attach it to the motor, it will help keep it from tearing. Trying to hit the 1k subs, throw me one if you have not. Thanks!
Did you know that in Gods laws, 613 plus 10, which the church says we're no longer under, that He requires if you borrow someones tools and it breaks on you, He expects you to repair or replace it and that's what you did, thus in that action you are a righteous man and He will reward you for that act!
U will only get maybe 40 hours out of that chinese rmw 2.2g24 pumps are garbage dont waste ur $100
Bees wax my ass.
Actually goats milk wax.
How do you drain and refill the oil in one of these vertical pumps, without disassembling like that?
Old one had a drain plug, new one didn't. So the answer is, you can't.
