How To Pull Apart And Inspect A Chinese Axial Cam Pressure Washer Pump From Amazon. Part 2/2

[@ItchyKneeSon]

The bolt pattern of the 3 'legs' of the pump only allows for mounting in one position. You have to be careful to buy the correct orientation of the water inlet/outlet. A good addition to any power washer setup would be an in-line filter to rid of any solid contaminants that could mess with the pump internals.

[@pontgta1]

Do you know where i can get the black seals for the plungers , the oil is mixing with water. I am assuming those keep it from mixing with the water.

[@ranman8541]

Glad I watched the video. Had ordered same pump , tore it apart after watching this video and found dirt and grindings inside. I marked the outside of the pump from top to bottom with a magic marker before disassembling to assure proper reassembly. Old pump had a 75w90 sticker, so that's what I used. Thanks !

[@bassntruck]

Glad it helped.

[@patricks5575]

Ive seen axial pumps all fail the same way, eventually water seeps through those black seals and mixes with the gear oil and turns it into a grey milky mess and it's game over.

[@drteknical6571]

Just a conversion note: that 22mm wrench is replaceable with a 7/8". 22mm=0.866". 7/8"=0.875". The 7/8" is .009 larger and will work on a 22mm bolt just fine. A big help if you don't have metric in sizes bigger than 19mm! Good video. My Chinese replacement pump has been acting flaky for a while now. When I replace it, and I'm sure I will have to, I'll use this guide to prolong the pump's life. Good, clean, lube is almost everything in keeping parts from wearing. Wearing = death.

[@AK-kj6ec]

Excellent video.... I have the same exact pump, sort of, mine is 2600 PSI, However has the same exact features which is helpful for disassembly/assembly. I forgot how to break into it & put it back to together without blowing it up so to say. You're the first person I've seen fixing a Power washer pump on a washing machine haha... Hope you didn't crack the porcelain. Good job Bassntruck... I am now a subscriber.

[@bassntruck]

Thanks My toolbox was covered in crud and we had just gotten a new dryer, so the obvious choice was use the old dryer. LOL Going to try and get more content up like this once I get the house rebuilt.

[@knighthawk86855]

Your a stand up dude, for replacing the pump.... I have done the same thing, and great video.

[@GraveDigger580]

I'm repairing my grandmother's pressure washer pump. The bolts snapped at the water housing. Lost pressure and started spewing water. Getting the bolts out was a challenge but I got them. Thanks for the video it's helpful. Strange though there's a sticker on this pump that says to use 10w - 40 oil in it.

[@AP-gx7uh]

I like it coming out the front better too. Pump to frame only mounts one way. The two pieces of the pump can mount 180° out. A perfect example of the real Murphy's Law.

[@Yhrim70]

I can see when connecting hoses and while using it, why coming out the front is better. But how about when moving the washer? Still good?

[@tedtolentino4955]

Thanks, and very helpful to see how these pumps are generally constructed and put together. I have an older 2600 PSI pump which has built up some scale and corrosion over the years. Since the housing of the pump has brass parts I have found that a product like C-L-R is not recommended as it can damage the brass. Do you have a suggestion of a cleaning solution that would work on the scale build up and corrosion? Thanks

[@bassntruck]

Not really but I hear Vinegar may work.

[@joelwilman8712]

I was about to point out that I thought you had installed that last piece backwards and then you mentioned it! Great video. Very informative. Thank you very much.

[@wk6927]

Excellent video . Very concise and informative for DIY guys like me. Thank you for your great contribution to KZbin DIY community.

[@steveworthington6857]

my ratchet sounds a bit like a duck. Classic line man. Thanks for the video!! It is very niche to see what's inside.

[@timvatter2559]

You had a 1 in 4 chance of getting it bolted back correctly. The 4 bolt pattern is square. The 3 bolt pattern on the pump head and the engine are fixed. You can clock the 4 bolts to change the direction of the hose fitting. Check and mark before unbolting it.

[@michael931]

He used the 3 engine mounting bolts which are fixed. He had no choice on the mounting position. They make another version that points the other way.

[@RyVonD]

He's saying that when you put the head back on the pump housing you can clock it in different directions. The guy making this video should have bolted it back on 180° than where he did so the hose connection would have faced backward instead of forward.

[@travisclarkin4277]

Need to change mine. I’ve used it a few times so I’m sure there’s debris from the break in process and like you mentioned I’m sure it’s filled with the cheapest oil possible.

[@rhodonbrown81698]

What was the oil weight did you us? Mobile synthetic ? Good video.

[@octaviofuentes7781]

75/90 gear oil

[@stephengrant2677]

I just tapped a hole and plugged it for oil changes. Put grease on the bits to collect the chips.

[@bassntruck]

The unit I removed had a drain plug IIRC. I thought about adding one but it was not my machine and they would never change it anyway.

[@Eric_W]

Finally a video that shows about how much oil goes back in the pump! :) Gotta love this guesstimating we have to do sometimes... by the way the manual didn't specify how much oil it needed, although it did specify what type of oil... lol Thanks a bunch!!

[@bassntruck]

Eric, I just filled it to where it was when I opened it up. Thanks

[@Yhrim70]

I read these are supposed to use straight 30 weight non-detergent oil. Is gear oil better?? I'm rebuilding an even crappier pump. The female coupler where the engine shaft slides into, the hole in the coupler goes all the way through. So you have to assemble the entire pump first, then fill it with oil, then install it on the engine without spilling the oil.... There is just a stupid rubber gasket between the top of the pump and bottom of the engine, that's all that keeps the oil in. In any case, I think I will use some synthetic gear oil like you show instead of straight 30 like I've read on several sites.

[@82rotaryman]

30 weight non detergent is for the pump motor. Generally you don't ever replace the gear oil in the pump drive on these style pumps because the pumps don't last long enough for it to need changed. Therefore the manufacturer doesn't specify what's used in it. Most people's mentality is throw it away and buy a new one because they are cheap. This guy was looking to stack the cards in his favor that he could make the pump last a little longer. But the weak link on these pumps has always been the plastic check valves that they use inside the high pressure side of the pump. It's just planned obsolescence unfortunately.

[@nathanield.4527]

At 14:04 when you are installing the housing cover, have you ever had to change the o-ring seal that prevents the oil from leaking out of the housing? If so, where do you get it from and how do you know what size to get?

[@bassntruck]

I have not had to replace that. But if you needed one just measure the width of the space and the thickness of the old one. You can find them online easily. I would error slightly smaller on the width of you come across and in-between size.

[@cc9z]

i just put a new pump on my washer and can i drain and flush it with out taking it off the motor

[@rolandorivera427]

Same question here. Lmk

[@bobbynanan3875]

Great video. This was just the video I was looking for .I had bought this exact pump but was not sure how to replace the 'garbage' chinese oil . Thanks

[@bassntruck]

Bobby, glad it helped you.

[@herick404]

Nice video !! Do you know where can I order the parts for the exact same pump?

[@rhodonbrown81698]

How is the pump now. Did it work out? Any problems?

[@enmanueljimenez3239]

thax for your video is great, can you please let me now, whats is the name of the first part that you put at the pum?

[@bassntruck]

Are you asking what is the name of the first part I put in it when I started putting it back together? The first part is a bearing, axial cam, bearing, washer plate, and the pump assembly. I hope that answers your question.

[@dbaker3264]

Forget the spacers!!!. All you did is lower the pump down farther below the engine plate than before, and if the pressure washer ends up on the grass, you just burns the grass up faster since the pump will get hot. So lets say that if you need to space the pump down 1" from the shaft being too long. Take a grinder with cut off blade, and shorten the end of the motor shaft 1-1/8". As for key, don't be in a big rush to cut it down, since if up the shaft a touch in the groove above the pump on the motor shaft, works out better, then trimmed so it only fits the groove on the pump alone. Last one, and oiling the upper pistons are fine with gear lube, but on the other rubber seals/O rings that you can get to, use Silicone/dielectric grease before you start putting the pump back together. Also, pull the unloader since you only have to pull the U clip, and go to town on greasing the O rings on it with silicone grease as well. The seals greased, will last a lot longer and easier to pull at a later date. As for the unloader, if you have a way of measuring from the end of the lock nut to end of shaft to put them back on with the same amount of spring pressure, then you can pull the unloader spring assembly apart, to grease the Two O rings in side of it so those O rings last a lot longer/ to prevent unloader binding so less rod bending over time; forcing you to have to replace the unloader. Also, Silcone grease the end rod section, and work the grease in the pin channels to prevent unloader end rod binding that will not allow the pump to build up pressure when it stick all the way forward.

[@nathanield.4527]

Outstanding tear down and build-up video! I noticed my pressure washer pump had some oil leakage after being in storage in my shed. Do I need to replace the o-ring or should I just try tightening down the bolts? I never opened the pump yet and it was brand new before I stored it.

[@bassntruck]

Making sure the bolts are tight costs nothing. Hopefully you didn't have water in the pump and it froze while in storage.

[@michael931]

Are the annovi pumps as bad as they seem?

[@stx38]

Thanks for the excellent instructional video; it gives me confidence to tackle the one I have in the garage. I would add that the proper bolt torqueing process is to do opposite sides in turn, gradually like you did, but the key is to get them all the same tight.......at some point you need to use a torque wrench, an educated guess to torque would probably work.

[@bassntruck]

You are not incorrect that a torque driver will give most people an exact tightness. I did not know the exact number so I can not give that. For me, I have used torque devices enough to be able to tighten most things by hand and get it very close. The housing bolts are not really mission critical if they are tight. I doubt the tolerances are tight enough to matter if it deflects slightly by over tightening.

[@jerrybumstead4943]

My pump water lines when connected to motor are facing toward the frt.Can I reverse ti water connecton to pump? So my water hose can connect in the rear???

[@bassntruck]

Depending on what pump you have you usually can turn them around to at least some degree. Either by just unbolting it from the motor and rotating it or you may have to take it apart to spin it around.

[@jefferywright4204]

You mentioned several times about metal fragments and you thoroughly wiped out the casting, but did not seem to clean the bearing plates and other internal pump components. Shouldn’t they also be cleaned before filling with oil and reassembling?

[@bassntruck]

I wiped down everything before putting it back together. The metal pieces were likely formed when they tested the unit. All the large pieces were in the bottom.

[@marcosalazar5333]

great video. I just got a Mastercraft 3100 psi with that same pump. I already ran it. any suggestions as to what I can do?

[@bassntruck]

Marco Salazar Change the oil. Should give it the best chance of long service.

[@ukgardener973]

Fantastic video. What oil did you use in the pump?

[@perryj20]

Nice work! So I have a question: Since it's been 5 years since you posted this video, I'm curious if the cheap Chinese made pump is still working (assuming your neighbor still is your neighbor and still uses the thing). I have one that has lasted over 15 years and finally gave out (the pump part). It came with and Annovi AR (Italian made) pump but the cost of replacing just the pump (exact replacement) is twice what I originally paid for the entire unit. Even the AR rebuild parts I need are more expensive than an Atima brand (assuming Chinese made) complete pump. So I'm just curious if you or anyone on this post has had good luck with Chinese made PW pumps. Would like to know before I go that direction. Thanks.

[@bassntruck]

I honestly have no idea. I am no longer in that area and have not heard from him since.

[@SheikShak]

Well done my friend.....got a question for u....what’s the purpose of a “ quick start” on a pressure washer pump

[@bassntruck]

Sheik Shakur As far as I am aware it has nothing to do with the pump. Just that the motor will start in 1 to 3 pulls.

[@SheikShak]

There a plug called the easy start that fit on some of these pump....with the ball and spring behind....

[@bassntruck]

Sheik Shakur That is just a pressure relief valve so the pump does not try to compress when starting the motor.

[@KhanhNguyen-xj6qv]

Hi! can you send me the link to order some spacers like the one you used? Thanks

[@bassntruck]

I just used some bar stock I had laying around and drilled some holes in it. Here is a link to some bar stock or I found some spacers that are cheaper and might look nicer. 1" square tube: amzn.to/2YTaIOW Spacers: amzn.to/2AbJ8C8

[@KhanhNguyen-xj6qv]

Thanks, I just bought a new pressure washer from Costco. Do you think I should change the pump oil? That pump comes with the engine from the manufacturer

[@bassntruck]

@@KhanhNguyen-xj6qv Not sure why you would need spacers then. But I would change the oil if you want it to last. Would also recommend changing it based on use over time.

[@KhanhNguyen-xj6qv]

@@bassntruck I asked for the spacers because I was trying to repair my aunt's one. Her Honda engine was seized so I bought another engine to set up with her old pump. The new engine I just bought has longer drive shaft so I changed the bolts which are also longer. That is why I need some spacers. Btw Thank you for answered my question. I will change the pump oil as soon as it arrives, I am still waiting for Costco ship it.

Hi, some people use engine oil, is it ok to use gear oil? Thanks for the sharing :)

[@bassntruck]

Glad you liked it. You can always try putting some oil in it but If the damage is already done it will not help much. I tried it on an old pump and it was a waste of oil and time.

i meant i would put that oil in a new pump if i get a new pump. i got my older pump half ass working . a friend of mine remachined a part on the inside of the unloader on it. i just put some 15w40 in the old pump to test out the reworked unloder valve. i ordered a new pump unloader kit, and anew carb for the engine too cause it only ran when choked.
