I have one with a Honda GX 160 that had sat outside for three years under a tarp through cold and snowy winters the oil was never changed it was never tuned up the pump burnt up on it, I got it home put a new plug and fresh gas and this thing fired up on 2 pulls, I shut it off I didn't know the pump was bad at this point but I figured that's why it was sitting outside for so long, found the pump was shot put a cat pump on it and it's been doing the business ever since!! Great video
I have the dewalt 4000psi 3.5gpm with the gx270. Bought the washer used and the motor is perfect. My pump actually blew up internally. Dummy me didn't notice when I tried it before I bought it that the unloader was tightened down all the way. Next day all excited I fired it up ran for a few minutes and bam. The fill plug blew off, pump was nothing but water and the internals were destroyed. I'm definitely going to get a cat pump and I'll have a stout setup with a hard lesson learned.
great pump, great combo, but the problem here is the tip size i think, you are supposed to choose the proper tip size according to the chart, 3000 psi (is what your pump is rated) @2.5gpm is a number 3 nozzle(starting point, go up until its correct), getting higher psi may seem like a bonus, but in reality, it is causing excessive wear on that pump and will definitely shorten its lifespan. so either the nozzle or some sort of restriction. with that gauge you should be able to test and adjust the tip size till it gets 3000psi with unloader wide open, anything higher means 1 of 2 things or both, excessive wear and not getting GPM that pump is capable of
*On my 3200psi 2.5gpm simpson washer with the honda gc190 engine I upgraded the pump to a 3600psi 3.5gpm My-T-M pump with the adjustable regulator and everything for $200. It's a commercial grade triplex pump with oil, return hose to keep it cool when you're off the trigger just like your cat pump and this pump cleans twice as fast as the stock simpson pump did. Well worth $200.*
Got a GC190 Simpson Power Shot MS60921. I need a quality replacement pump. Do you have any suggestions? Where can I look to find one that fits? Was your a Cat?
@@PaOutcast cat is up there at the top with AR, Giant, etc, but depends on your budget, but for a GC190 (5.2hp) id go with 4DNX27GSI, you can google that, its 3000psi @ 2.7gpm, probably the best but pretty expensive option
@@AnthraxVX those cat 4DNX pumps are great but the canpump 3wz is about the same performance and much cheaper, and they are well built too, I have two old mi-t-ms that were used hard and only recently did I have to replace one of the pumps simply because they were neglected and not properly maintained over the years
the AAA pump that had on it stock is not half bad. guy probably beat on it either not ever changing its oil or letting it idle alot. letting the preasure washer sit in bypass is probably the second quickest way to kill a pump other then running out of oil it it or maybe letting it freeze in the winter. or ran it without watter flowing first like he did when you went there. I always bleed out the air out of the pipes by running the wand held down without the engine running but the spiket on before I even start it as air is no good for a water pump.but nice find for 100 bucks
Man by the sound of it either good help is really hard to find or bad help is easy to find i don't know which is the case. One thing is for sure you got some bad luck with people trying to help ya hahahah. If I was you and I saw my buddy break off some threaded piece in my pressure washer I would have lost my shit. Good luck to you man. Oh and thanks for the recommendation on them CAT pumps, I'm gonna go ahead and take a look at one for my set up and see how it goes. Before watching this I had just thought you had to buy a new pressure washer every time your pump goes out. I had no clue that they made pumps that fit on any unit.
You need a bigger nozzle orifice probably like a 3.0 or 3.5 you dont want to go over the rated working pressure of the pump meaning when the trigger is pulled an water is spraying. Not to go over the rated pressure
I thought not to go over the psi when the pump is holding so if the washer was rated at 4000 psi u set the holding pressure at 4000 then u get around 3500 psi when trigger pulled correct me if I’m wrong
new its ez but big$$$ i just picked up a gx390 used about 10 times, looked brand new, with a GP pump 3700 psi 4pm for 500 bucks :) gp pumps may not be the tippy top quality but are cheaper to repair, and with as little as i use them and properly store them, itll last me forever id say, maybe 50 bucks here and there for some valves/packings etc. i took apart the carb and fully cleaned, replaced oil in engine and the pump, since teh guy didnt know much about maintain things lol but everything checked out good, the deals are out there you just gotta look and be patient
That pump is for an electric motor. That might explain what it’s over 3000 psi. But it looks like it could blow a parked car off the street. I like your set up. I just ordered a GX200 Honda with a cat pump. 3000 psi.
i would think its for an electric motor too, but i purchased mine with a gas motor. the milky bubble could be from not having the correct cap on. need to put on the regular cap and remove shipping cap.
you can use a screwdriver, a larger one, one that will touch bothe sides at the same time....slowly adjust the screwdriver to get a snug fit, and start slowly unscrewing it. anything you can find to fit both sides and grip will work, its more about the size of what you use. let me know if i can help any further.
Idk if this particular pump is compatible, but theres a wide array of pumps that would fit that engine as long as it's a horizontal shaft. If its vertical shaft you have less options,but it's still easy to put together. The biggest thing is shaft size on the engine. Hope that helps
Is the T fitting for the return line special fitting or just a T fitting for high pressure , because my cat pump doesn't have a bypass, i think is just a regulator, but looks exactly like yours except for the bypass.
Take off the bottom bypass hose and plug that opening and take off top bypass hose and replace with longer hose put into buffer tank that way the bypass water is cold and fresh all the time won't get hot and ruin the pump.
That is very good advice. Having the water just looping around and getting steaming hot does the pump reliability no favours at all. We have a Cat pump on a trailer bowser and it loops back into the main tank so not really much likelihood of getting an overheating issue.
@@stephenyount3148 I didn't say they were perfect. If it's mechanical it can break. I've got an FX Kawasaki engine on one of our big commercial mowers, and have had issues with it in the past. I still love and have faith in Kawasaki engines.
Victor Castro Exactly. Dewalt doesn’t produce pressure washer components, they just put their name on them just like most other companies. It’s a pump and an engine.
There is a formula but I would have to look it back up. Just guessing I'm going to say around 2500 psi at 5.5 gpm with that size engine. But fact check that
It's not enough horsepower to sustain that much pump volume. You could maybe get away with a 3 gpm pump on a 190cc engine. A 4 gpm pump on a 9-13hp engine,or the 5.5 gpm pump you mentioned on a 13-16hp engine. Even washing houses youd rarely need more than 4 gpm.
A downstream injector is what I have used for years. I never use the one on the pump. I have mine with quick connection and I take them of when I go back to high pressure
@@walkingwormfood9628 it's downstream in the original configuration, however he has installed an unloader loop that cycles the water back through the pump when it gets hot. That's after the injector, so it would pull chemical through the pump, but he says he uses a different injector so it doesn't matter.
i would ug the chem injector with a purchased screw plug then use a disconnectable downstream injector. they run about 1:10 injection rate so it will change your dilution ratios.
@@mikecurtis1111 i have contacted them about this, they claim the relief valve keeps the heat to an acceptable level...but as we all know, thats bs. i dont trust people who want you to buy new pumps.

Everybody talks about how good cats are , well I’ve saw a few with problems, my uncle washes 8 hog houses and they have problems with their cat pumps and he’s got General and has tried them all, and between them two brands they are about the same , I got me a Honda with a cat pump because people claim they are the best but I had problems with it the second time I broke it out to wash my house which was a year apart, the unloader was not unloading, so I took it apart three times and didn’t see anything wrong with it, only used it twice and had problems, well I could’ve carried it to a cat repairman and let him tell me it was my fault, not the pump and let him rape me or get a new pump, so I did, it was a ar viper and works like a charm
Hi Dan, We recently watched your video at: ua-cam.com/video/OBFnVaDMMm4/v-deo.html Do you have any knowledge or experience to resolve overheating CAT pressure washer pumps? We own a CAT Pump Model 2SFX30GS. It has developed an overheating problem. It overheats after 3 mins run time. Our Pump Tech replaced Valves, Valve seats, Seals, Bearings, Gaskets and Unloader. Can you offer some advice as to why overheating still occurs? The original overheating event melted the Oil Fill Red Cap. Thank you. Regards.

Yes Siiir I see you received your CAT Pump and installed it.
yes sirrrrr I did. However I will be making another video about CAT pumps soon. Look out for it because it will be very useful info
you need to take that black vent plug out before using the pump. it's in the red bell on top.
What does the vent do, I just realized that it is supposed to come off. After this video, I went and took it off
@@evansantos9148 it is just for shipping.
ya, needed to keep the fluid in during shipping. need to remove it so the fluid doesn't heat up and ruin the viscosity.

What is the clear line connected to the pump and pressure gauge.
Is the return line, when wand is not in work , but need to be before of chemical inlet and not after like this one
Is the T fitting for the return line special fitting or just a T fitting for high pressure , because my cat pump doesn't have a bypass, i think is just a regulator, but looks exactly like yours except for the bypass.
Make sure you use a 2.5 gal/min tip or you wont get correct psi rating
Actually the psi is measured always at the pump. The pressure can always change after the outlet because people use different setups.
Darren Airey Not correct.
Hi Dan can you do me a favor I have been on all the websites to find out how the shutoff switch is weird up can you send me a picture of it
Take off the bottom bypass hose and plug that opening and take off top bypass hose and replace with longer hose put into buffer tank that way the bypass water is cold and fresh all the time won't get hot and ruin the pump.

Also helps to use a weep trigger gun.

Ken Kuzminski I just got one of these today. the model number is 4dnx25gsI. got it at northern tool for 359. hope that helps
Kool video
I don’t think you had to move the engine, just turn the pump over and swap the vent cap and drain plug. The manifold would then be on the other side.
Check how cat pump work, in this motor running counterclockwise this is right way to set the pump, less friction in the pistons
I'm going to put a 4 gallon per minute pump on mine
