- Some new and some old parts combined to make a high end commercial pressure washer for half the price.
Honda 13hp with 4gpm 4000psi 66DX Cat Pump.
CAT pump: amzn.to/2gRc4CA
50' Hose: amzn.to/2FJ2GMh
Wand 4000psi : amzn.to/2pd7of0
Quick Connect Adapters: amzn.to/2FEViW3
WINTERIZER: amzn.to/2gQoAlI
Ideally a belt drive will give longer life. Belt drive units are the ultimate professional pressure washers and they will get the benefit from being able to gravity feed out of a water tank, lower pump temps after hours and hours of straight running and ideally more longevity. Personally I will never run this for hours on end nor do I need to gravity feed out of a tank. If you plan on running it for a business, 25+ hours a week, for years, go belt drive. But personally I didn't want to source pulleys, belts, make guards or spend the extra for a belt drive pump. The cat pump I used has an average lifespan of over 3000hours, so I could use it for 3 hours a week for the next 20years before I need to do a major service.
CAT spec sheets show the only longevity difference is bearing life due to rpm differences in direct(3600rpm 6k-10k hours) vs belt(below 1200rpm/1/3 engine speed 12k-18k hours).
Direct Drive Pump
Pros: Compact design, lower cost, more efficient
Cons: More vibration and heat from motor transferred to pump, higher rpm
Belt Driven Pump
Pros: Longer life from lower RPM, belt absorbs vibration, won’t overheat.
Cons: More maintenance, higher cost, less efficient.

Now I have pump envy. Thanks a lot man! Beautiful pump. haha
Ozzstar ha ha. Thanks for the great comment.
What about bleeding Air out of pump before start up?
Pro trick : watch movies on flixzone. I've been using it for watching all kinds of movies these days.
@Langston Felix Yea, been watching on Flixzone} for months myself =)
@Langston Felix yea, have been using flixzone} for years myself =)
UPDATE:1 year and still cranks within the first 2-3 pulls. Probably will buy another when this one finally does bite the dust ruclips.net/user/postUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX . No issues at all. Very happy with it.UPDATE: After 6 months of use and over 70 uses I would still highly recommend this pressure washer. It does vibrate a decent amount but never had it “walk” like others have mentioned. No oil leaks, still seems to run like the day I bought it. Still cranks within 2-3 pulls every time. Very happy with my purchase!Have used it about a dozen times now. Plenty of power, cranks up on 1-2 pulls every time. My only complaint would be I wish it was a little taller to make it easier to walk with it (hits my ankles a lot) and that the two hose connections were a little further apart but it hasn’t caused me any issues. Seems to run a good 1-1/2-2 hrs on a full tank, overall a well built machine and definitely worth the money in my opinion.
pressure washer tech here.
we rarely have to rebuild a CAT pump...
that's because the parts are too expensive and we throw them in the garbage.
Hotsy makes a good pump. Lifetime warranty against freezing.. Cant beat that.
yes they do I have used their heated pressure washers, amazing build quality and performance. With Hotsy though to get the level of performance he has here you're looking at $2500, this is a great option for someone starting off in pressure washing perhaps they could mount this on a trailer with a small pump running to it and have a good trailer for relatively lower cost then a brand new Hotsy trailer unit.
@@jhomrich89you can get a 4000psi belt driven cold pressure washer for $1700
most homeowners/small business need about 2300-3300 psi. Those are around $1000 depending on your distributor, Manufactured by Karcher N.A with a Hotsy style pump head and crank case.
They dont make the classic red Hotsy pumps anymore. Its closer to a General pump now.
Hotsy/Landa/Mosmatic/Pressure Pro/Karcher are all one company now. Karcher bought them all up. Alkota and Hydrotek are one company now. Aladdin is its own company(wouldn't recommend).
The CAT pump you are seeing is essentially a private labeled pumps for whatever distributor is throwing together the chassis so they can charge more for the CAT name and parts.
These are not equivalent to the commercial/ industrial CAT pumps that CAT built its name on.
my 0.02
most of the guys i see starting out take the handles/wheels off the cold units and just mount the chassis to their trailer. i wouldnt advise a guy starting out to buy a CAT pump. i would recommend something that has cheaper service ability and rebuild ability. #1 choice -HOTSY #2 choice - Comet pump.
need them and are not buying commercial/industrial versions. CAT is essentially private labeling for other manufacturers.
That's what I've heard about Cat pumps; they are too expensive to rebuilt.
Can I buy a replacement for a 2DX15ES.KB pump? I really would rather have a cheaper pump, but one that won't freeze might be even better. Really appreciate any help.
I have a pressure washer that has the Annovi Reverberi XRCV4G35. It's a 4gpm 3500 psi pump, and it was made in Italy! Now they build their pumps in China. It's a commercial grade pump, the only pumps that was used on the type of pressure washer it is are the belt driven pumps. It's a awesome pressure washer, but they have been discontinued for a while now.
Just recently bought a hurricane 4300psi 4gpm but I will say that keeping the trigger squeezed is the number one thing that helps longevity. I bought a CH back in 01' and it still works after 17 years of personal use.
Congratulations for you checking one off your bucket list. That thing is gonna be great for you! Your dog is outstanding! Unbelievable coordination and skills!
This dog loves to jump.
Great tips on keeping the water flowing. Always good information, Moe.
Thanks George.
I agree with you about CAT pumps! My one AAA pump was shot after two years and my previous two (four and five years old) with General pumps have practically no pressure. They all had pressure gauges, unloaders and inlet filters with rarely being run longer than 60 seconds without the trigger or flow relieved. I find that ball valves are a necessity when switching between the surface cleaner and gun and letting the pump cool down after use with a low idle run and no restrictions on the line. It didn't matter on the first three for they just didn't last. I now have a CAT 4200 psi @ 4.0 gpm and so far after eight months and close to 300 hours of use it's been great. I did change my methods and now run 50 feet of hose and position the pressure washer where I can continuously work without having to stop and move, this lessens my operating time and it's worth spending the money on a longer line. Granted pressure is reduced but with a high quality hose it's minimal. Awesome video..
Thanks for your personal input.
My pop bought a commercial pressure washer back in the day, Brigs industrial engine with a 2800 psi Cat pump, other than bad gas issues and a new starter cord that thing still puts out like a champ ~20 years later.
I'm retired but work part time for a Cub dealer. Most of the pressure washers we see in the shop are simply no maintenance. They get used once then sit for a year in freezing temps. I bought a new cub cadet with a Honda GX motor. It's a CC3600. I ran it for a couple of hours then I changed the oil in the pump to a good pump oil. After I use it I run water through the pump without a nozzle on the wand. This runs a larger volume of water without creating heat. I also use pump saver in the pump if it's going to be setting for more than a couple of weeks. Hopefully I can get a lot of use out of it.
Great video and nice pressure washer.
Good tips, when my washer dies this is what I'm making! Also watched and saved your vid when you made the bead buster. Great videos.👍
Thanks Ed. -Moe.
You are in my top 10 of guys that know good stuff. I have over a thousand DIY's in my RUclips library so Top 10 is GOOD LOL. Thank you for helping me learn :)
I'm about 6 whole years, late to the party, boy am I glad found your channel...Terrific video thank you!!!
Very good video thanks for doing this one. You're a smart fella and I always enjoy watching and learning new things here. Keep up the good work.
Thanks, I'm glad you enjoy the videos.
Looks great man. I love seeing the mix of new and used. I have kicked the idea of making an attachment for my mower to use its PTO to drive a pump head. I just dont like keeping another small engine around that I use rarely.
I toyed around with a pto driven pressure washer as well. It's a great idea. They have belt driven pumps that spin at half the rpm of these direct coupled pumps and would be ideal. I just needed the portability and I have half a dozen big engines laying around.

Helpful video.... I guess the saying is true. You learn something new everyday. I never knew that you had to constantly run water thru the pump. I won't be doing that anymore.
THANKS FOR MAKING THIS VIDEO !!
I searched for things you can do with pressure washer pump and got this video. This would be a good idea. Sometimes obvious things are oblivious. Thank you.
Wow that's a really nice machine. Very impressive. Make sure your garden hose can deliver 4 gallons a minute also. Great video!!
Thanks. It's expensive but I'll be able to make money off of it in years when it time to move it along. In the mean time I'll get a lot of work out of it.
Great video: I have a 13 hp Honda pressure washer, never had an issue. I drain it out and add the RV antifreeze after every use. Some times I use soluble oil additive in it for long term winter storage. Thanks for the video's.
That's some great advice to keep them alive.
Great video, good memories, i did the exact same thing, same engine, same pump. I love those Cat Pumps. After about a year of use I took my nice blue Cat pump off and put on a red Comet Pump because it is 5gpm, my psi dropped to 3500psi but the increase in gpm cuts my job time almost in half. As soon as i win the lottery, i will upgrade to an electric start and 8gpm for my bigger jobs. Anyway great video...
Hey Thanks. 8gpm would be amazing!
Great video. I almost bought a cheap washer until I did my research including this video. I will get a commercial one like yours
I'm extremely happy with how it works.
Cat Pumps, top notch.
I have an 110v electric NorthStar pressure washer with a Cat pump that I got from work about 4 years ago. I was told that it didn't work and I offered to take it off of their hands since it was just sitting in a corner of the parts area of the maintenance shop for years and they wanted it gone.
Turns out it works perfectly. It's just a little on the weak-side compared to the pressure you would get out of a gas powered pressure washer. All I have done so far is replace the pump oil for good measure. I might try adjusting the pump a bit to get more pressure, I know that there is a pretty detailed procedure regarding pressure drop and such to dial it in perfectly. Pretty foreign to me, though.
Anyway, it works well enough for light duty washing of the car and the house's vinyl siding and windows. Considering it's free, I'm more than thrilled.
Can't beat a free pressure washer, especially one with a Cat pump.
This was very informative and a great project, I'm going to try to make a vapor blasting machine one day, or at least a pressure parts washer. Keep up the good work.
That's exactly what the main purpose of this is going to be. I'm going to use it for wet sandblasting car parts.
This is exactly what I was looking for, thank you big fella.
All the high quality pumps I've come across with "issues" almost always needed only a valve kit (which is a simple and cheap fix) and then were back up and working as original. People leave water in the pump and it rots the valves. IMO the AR pumps made in Italy and the cat pumps are both really good high quality made units!
I've serviced and resold a fair amount of pressure washers with AR pumps, I think they're good. Cat, AR and General are the most known commercial pumps and all last, but I think Cat has the best reputation for themselves.
That's my experience as well. People either leave water in them and it freezes or trash is sent into the pump because they don't flush the low pressure line before connecting to the pump. Few pulls on the cord with the high pressure side open clears any pump I've had.
looks like the same setup I have, was given to my boy because the pump did not work, rebuilt the seals and works great.
cat pumps are great, only problem I had is springs rusted in pump resulting in no pressure, think they were like $25 bucks & back up & running.
The big comet pumps are really good too. I work on them professionally and honestly I see more cat pumps with issues than the big comet pumps. Although it’s usually just water seals, valves or unloader.
I like the setup, plan on doing something similar next summer
Thanks.
Really appreciates that pump picks it and puts it down 80 times 😂😂 thanks RUclips for the recommended. 👍
Very nice job. Good looking unit.
Wow! What a great and useful video bro! Thank you! 👍
i replaced my blown no name pump w/a comet pump on a honda eng years ago... been working fine... your 100% right..... no one cares or realizes the quality of the pump... great video
Those no name pumps are destined to fail. It's kind of a shame.
I have had 4 washers come in this month. You are right
I haven't had any all year, but years past they're coming in all the time.
I had one come in with a bad motor not pump. Of course I used a motor from another washer that had the pump die.
i just wanna know why your profile picture is your lawnmower
First video I seen were you build the pump then ran the pump.....great job!!!!
Thanks for watching.
Nice assembly using some recycled part.Thanks for the info on the pumps. I just missed getting one of these at the local dump that looked like new. As I was driving out someone dropped it off but one of the workers “ helped” him roll it away. Missed it by seconds. Maybe next time. Hey stay well, JoeZ.
Thanks. Yeah, can't get them all.
Those CAT pumps take a beating and just keep going. I have one on an old Excell power washer I’ve had since the late 90s. Putting the anti seize on the shaft was a great tip. These things get wet with normal use. They WILL rust together and you can practically destroy the pump trying to get them apart. I wish I had one of those hot water power washers. Those are great for washing engines and emulsifying grease and oil. Nice build Moe. Between that cat pump and that Honda engine, that setup should last you for years.
Last year I picked up a large propane powered hot water/steam pressure washer. It doesn't spray very hard but melts everything and leaves the surface non-greasy. It's a handy tool for sure.
Simpson...........been top of the line forever dude.
Got a 2000 5dx I love it so much!! Just change the oil with 30w non detergent every 20 hours or so and keep water ALWAYS going through it don’t burn on it!
Those are good pumps.
Legend mate, thanks for helping us out.
Thanks, I'm glad you liked it.
Depends what you use your washer for.. I love cat pumps for commercial grade washer. Have a 4K psi Honda gx360 motor with the same model cat pump, AWESOME for BIG pressure washing needs. I’m a detailer, for cars you’d maybe want to go with an AR North America pump and a smaller engine maybe a Honda Gx200 or even a harbor freight predator engine lol
Love your videos man, so much information. Got a pressure washer from my father that he built, I think the pump is going bad now tho.
Thanks for watching.
If it’s a good pump you can salvage it cheap with parts.
Another useful video. Thanks, great channel!
Thanks.
OMG I am uploading a video now of a pressure washer I built. I used the same Honda engine and almost the same cat pump!!!!!! I cant believe it. lol I thought I was the only one who would do this! I git the pump for free as well!!!! great job1
That's awesome.
👍👍
Thanks for sharing and take care.
Thanks for watching.
Learned a little Today. Thanks for the Video
Thanks for watching.
Thanks for the video! Do you know where I can get the bolts for the gx390 that you used to bolt the pump to the engine? I can’t seem to find the size of the bolts anywhere.
Cat pumps have never let me down
That's what everyone tells me. I really only have experience with what I have to constantly fix and Cat isn't one of them.
Thanks bro love watching all the videos.
Gomepez Thanks man
Just picked up a gx340 with a cat pump for $100. I got it running and the pump works, the pressure bypass valve needed the spring and ball re aligned. That was it! I was so excited i got it working. Just need a cart and sort out some plumbing.
That's awesome
i have a landa belt drive pressure washer with a honda gx390 on it i picked up on cl for 50 a few years ago. needed a carb cleaning and pump is great. love my landa!
Landa makes some good equipment. $50 is a great deal.
sixtyfiveford I've had it for 5 years or so still working great
General Pumps have served me well fo
r years. I bought the exact same Cat pump and one of the plastic valve things already broke .
Yes, but General Pumps makes high end and low end homeowner grade so I don't generally make the blanket statement that people should buy them. The point I was trying to make in the video is you get what you pay for. A $600 Generally pump is going to be just as good as an AR, CAT, etc. I generally recommend CAT simply because they don't make budget homeowner pumps.
Amazing that your 'random' engine mated to your 'random' pump perfectly.
They're pretty much all standard sizes.... If you get a pump that requires a 6.5 hp engine, most all of them have a 3/4" shaft, on a bigger 11-13 hp engine like this they're almost always a 1" shaft. Small engine stuff is pretty standardized, the mounting patterns are almost always the same unless you're using a specialized unit of some sort. Usually not hard to swap a Kohler, Briggs, Tecumseh, Honda,etc if they're all in the same HP class and shaft style. It's not like automotive engines where everything uses different bell housing patterns, crank patterns, offsets, etc and you need adapter plates to hook a powerglide to a Windsor.
I'm note sure what pump is on my dad's but it's been running 20 years at least and is probably his most used small engine. It put it up against a cat pump any day. I'll check and see what is is and update. I'd also recommend turning the pump down ever time before you kill it, makes starting easier and extends pump life.
Excellent vid my man!
Thanks for watching.
spec calls for 18hp at 4gpm/4kpsi
nice pump btw, good setup
may want to consider a 1" supply if your unloader is pushing 4gpm.
your advice on not leaving the water in bypass is spot on
Yes, to be more than safe 18hp would handle this effortlessly. I did have a 16hp and 18hp on standby if this 13hp Honda didn't cut the mustard. Cat calls out for 11hp electric with this pump and notes that gas engines vary, but don't give an exact number. HP really means nothing in a gas engine and torque is the only true figure. HP is heavily based on the simple speed of the engine, multiplied by the torque. By simply making the engine spin fast I can make a 13hp engine put out 18hp but nothing changes the true power number: torque. Anyways, convert the required spec 11hp electric to torque and you get 17 foot pounds as being the required force to turn this pump. The specs for a Honda gx390(13hp) is actually only 11.7 true HP but 19.5foot pounds of torque which is ample. It has no issue putting out the full power of the pump. In the past, engine manufactured fudged hp numbers significantly to increase sells. Years ago a massive lawsuit encompassed all of them and they paid some pretty big settlements. That is why most everything you'll see these days is only sold under torque or simple displacement numbers.
sixtyfiveford your response pretty much sums up why I think you've got the best channel on youtube
Good info on pump brands!
Thanks for watching.
This is a great video. Thanks for the info.
Thanks Marcus.
What pump would you recommend for a belt driven set up? I have the same Honda engine and it is paired with a Mi-T-M pump 3-0142. (3500 psi 3.5GMP) Pump is getting water in the oil. I have considered rebuilding it but I have found that a full rebuild is almost the same cost as a new pump.
Love this and would like to know how to configure an on demand water heater or boiler in the mix
Colter Bolton -That would be awesome.
Gotta be careful since not many pressure washers are made for hot water.
aguyandhiscomputer pressure first, then heat.
Bend the end of the nozzle a little to counter the force coming out of the nozzle...you can tweak it so it basically balances and you don't get tired as fast.
Worst advice. Bending the shaft will cause more stress on the arms. Instead of pushing straight back it will push opposite direction of the bend. If you bend it downward then it'll be pushing back and up. Then your fighting to keep it forward and down.
Great vid, thank you
The Tecumseh pressure washers at Costco last about a year, so I take them back and buy another every year. It's always the motors that go out on those ones. The last one, the engine started knocking like the oil wasn't getting to the top of the engine. Had the right amount of oil. The bold were unscrewing
Great catch for your dog!!!!! It must have attachment for soap.
It does have a soap attachment.
Good stuff, nice washer........and leaf blower!.....cheers
It pushes leaves better than my leaf blower.
*I put a Mi-T-M 3600psi 3.5gpm pump on my $300 simpson honda washer and it works great. Got the pump new for $220 so paid $520 total and have a real nice washer. Only weighs 75 lbs too.*
That sounds like a good combo. What motor is on it and is it horizontal or vertical?
@@ciphercode2298 *It's a little 6hp gc190 engine and horizontal shaft engine. The engine may be putting out a little more than 6HP now because I ported the muffler and re-jetted the carb and it runs the pump pretty strong.*
Not cheap but high quality very well worth it awesome job
True, but far cheaper than buying one with the same specs.
Think I will stick with COMET pumps
Had them all my life and never repaired very many
Thats is a really nice pressure washer. I know have a project coming up
Thanks, I'm glad you liked it.
Thanks that was a pretty informative vid.
Thanks, I'm glad you liked it.
I have 9 hires Honda with a3g30 annovi rebervari 3000/ 3 gal pump I bought in 98 and still runs fine!
Just make sure all the fittings before the pump and up to the bypass valve are stainless or brass (preferably brass). I'm having to replace the pump on my pressure washer, an Annovi Rebevari 2200psi 3gpm because someone had originally installed a galvanized T where the bypass line attaches to the input, and it rusted on the inside. There was also what looks like a stainless 90 degree elbow coming out of the pump, going to the regulator, but inside it's all full of rust. I'm replacing it with the same pump as of course the Honda engine has tons of life left (the original pump lasted 23 years). It would've lasted longer if it weren't for the rust getting into it. One of the ceramic pistons cracked (either from rust build up, or possibly from freezing- hard to say for sure), and once a piston is cracked, it doesn't make sense to rebuild. A new pump is cheaper at that point.
Love the dog at the end too!
She loves to jump.
Man that's a skookum pressure washer. Nice build
Thanks. I should give me a good life.
Can i use electric motor instead ? 2 hp would it be enough ? Thanks great
I would like one on my riding mower using a pully and clutch added for switching to it instead of mowing - 13.5 HO B&S engine.
Make a video
The problem with that is that the bearings in the pump are not designed to take a side load. The side load from the belt tension would ruin the pump. You would need to use a couplepillow blocks and a jack shaft to have any service life at all.
Why would u even wanna do something that silly
I always see a great engine and a blown pump LOL
I'm not complaining because it is a great source of engines for me.
Nice setup Moe! That should more than do the job.
Thanks. Every-time a get a commercial unit in and regret selling it off. Figured it was time to build one.
The TRIPLEX type of pump, from what I've read, is the best. Looks like that is what he bought.
Great advice
Awesome video!
Good info from the master! Cheers
No master, but thanks.
What do you think Gear drive on Honda IGX 800cc motor vs belt ???
Wanted to perform a home build with gear drive unit
not to certain on a belt driven unit ?
I was thinking about putting a pressure washer to gether using an old mighty mac sprayer frame, kind like a wagon frame. My question: Pros and cons of directly bolting the pump to the engine vs belt drive?
Ideally a belt drive will give longer life. Belt drive units are the ultimate professional pressure washers and they will get the benefit from being able to gravity feed out of a water tank, lower pump temps after hours and hours of straight running and ideally more longevity. Personally I will never run this for hours on end nor do I need to gravity feed out of a tank. If you plan on running it for a business, 25+ hours a week, for years, go belt drive. But personally I didn't want to source pulleys, belts, make guards or spend the extra for a belt drive pump. The cat pump I used has an average lifespan of over 3000hours, so I could use it for 3 hours a week for the next 20years before I need to do a major service.
CAT spec sheets show the only longevity difference is bearing life due to rpm differences in direct(3600rpm 6k-10k hours) vs belt(below 1200rpm/1/3 engine speed 12k-18k hours).
Direct Drive Pump Pros: Compact design, lower cost, more efficient Cons: More vibration and heat from motor transferred to pump, higher rpm
Belt Driven PumpPros: Longer life from lower RPM, belt absorbs vibration, won’t overheat.Cons: More maintenance, higher cost, less efficient.
That's one hell of a leaf rake, too!
It's my new go too for moving leaves.
Great info! I don’t concrete resurfacing and have a few pressure washers laying around. The motors are good, pumps no. Is it worth keeping them for any reason?
If the engine is horizontal shaft yes as they are direct bolt on to tillers, go karts, and a bunch of other power equipment. If it is a vertical shaft(like a lawn mower) then the engine is essentially junk and has no other purpose.
CAT pumps are awesome !
I've been impressed with them.
Honda the best engine to have.i bought a used factory Honda pressure washer for $150 paid for itself 10×
I've been wanting to build a stationary pressure washer driven by an electric motor with a switch, instead of a water trigger. I don't like running them either. But I was stumped on good quality high pressure pumps. The cheap electric one I had is virtually ineffective. It's not supposed to run constantly either, but does. I'm probably doing an autopsy on it soon.
Nice Setup
Thanks Man.
Great video, great info.
Could you please enclose-- what is the CAT Pump you installed. Good Video thank you!
I have a link in the video description for the exact model I used.
Great job. I have a similar power washer set up...Honda motor/cat pump, with issues: after using the power washer for 30 sec, the engine starts to sputter and dies, unless I stop spraying. Good gas flow, clean carb, clean air filter, new plug...thoughts?
Researched replacing unloader valve??
Unloader valve only if the engine stalls when the trigger isn't pulled. If stalling while the trigger is depressed/spraying water it's going to be lack of fuel or the oil level sensor with a Honda. To test lack of fuel get a pair of vice grips to pinch the fuel line. Run the machine and immediately when it stalls pinch the fuel line. Release the fuel bowl nut and measure the amount of fuel that drains out. To test the oil level sensor simply unplug it and run the machine.
What size are the mounting bolts that u need to mount the 4.0gpm cat pump to the Honda gx390? Where can I buy a kit with the bolts?
Good morning, can any one help please. I am looking for an instructional video on how to replace the inlet valves on a cat pump 279 please. Or if anyone can tell me if the internal parts for the 279 are the same as what other model thank you so much
Ok the question is: how to know what size of pump (psi) do I need depending on the engine horse power? For a 6.5hp engine, what pump do I need?
A 6.5hp engine is going to give you a pump around 3000psi and 3gpm max. You can go lower in psi 2500 and get 3.5gpm or just the opposite to 3500psi and get 2.5gpm. These are ballpark numbers. If you plan on cleaning things like cement, decks, ect you'll want to go with a higher GPM so you can do more work faster. Gallons Per Minute is a measure of how much water is pushed out. The more water the more debris will be carried away. If you want to blast small things like heavy grime off an engine then higher PSI will benefit vs GPM.
Great video, there are several pull start variations of the GX390 engine. Which variation do I need to match up with the CAT pump you have in the video?
Variation options QA2, HA2, etc... thank you...
I think the HA2 is a gear reduction 6:1 engine and not what you need. QA2 should be a 1in shaft and what you want.
Thanks.. QA2 appears to be the correct variation...
wow awesome and truthful video. A+
Great tips!!!
Hi great video, for a while I've been looking to invest in a commercial grade pressure washer, but now this is the way I may go I've actually got one of them engines in the corner of the shed. Is your water feed by hose or will it pump it's self from a tank? Thanks.
I feed this with the hose, but it can gravity feed from a tank. The spec sheet for this pump says flooded-75psi is the range.
Great job sir and nice post. I've done the same thing. Looked like a 8 or 9 hp engine. I had a cat pump that gave out on me so I've used general pumps to make a couple power washer and thinking about one more. I may use a cat this time around northern hydraulics stop selling the pumps I used and they were pricey 357 $ but last forever so far
Martin Schaffm. There are a lot of people that really like the General pumps. Cat pumps must sell more because even though other brands are equal or possibly better, they have one of the best reputations. A lot of people in the business live Comet as well.
most people say that belt driven is better less heat transfare less vibration and the key wont wield itself to the pump, what do you think? cheers
There's several other pump producers that make a good pump. Giant pumps in Toledo is one for sure. But yea, if you have a Cat you know you have a good machine.
For sure there are others with great pumps. I just think Cat is the most well known.
is this a triplex pump? great modifications.
yes cat triplex plunger pump
Great job Moe! Certainly saved the wallet and now you've got a machine that will last years! Cheers my Friend! Zip~
I was going to make a pto driven one to hook behind my 7016 but I had this Honda burning a hole in my shed.
