Planning on starting a budget pressure washing business and this would be a great way to step it up a bit.
Dad I’m just watching you know! Sounds like my sons 😃 great video
He’s something else lol
New subscriber. Keep the content coming 👍
Thanks for the sub, I'll keep them coming!
I'm going to have the amish build my pump skid. The number of Amish with hydraulic brakes for metal is astounding, itll take him 5 minutes to bend it. Then powdercoating from a family friend. Im excited to get this thing rocking
nice
Thank you bro keep em coming
Absolutely, thank you for watching.
@@KentuckyWashPros did you order the engine online or pick it up somewhere?
@@billyjennings6931 got it from a harbor freight store
What is your maximum psi with a surface cleaner?
I hit the button!! Thank you. I am thinking about doing this but just wondering if it would take off....
What do you mean take off, are you meaning being successful in the business.
@@KentuckyWashPros yes. I live in WV about 4 hrs from u.
Where did you get it pump n what's the part number?
Hey bud! Love the videos! Quick question for ya.....What size surface cleaner do you run with this set up?
I run a 19” whisper wash classic, you could run up to a 24” surface cleaner
Thank you
YW
Hi Jeremy, for the oil drain plug for the engine oil is it the 12mm that you got or is it an 18mm? Thanks in advance. Also is it the same plug for the predator 459CC?
It’s the 12mm and it should be the same
Hi. Did you do a gpm flow test for this machine? Thank you!
I did, it’s part of one of the videos I believe. I saw 6.5 gpm
Need to do one with the belt driven gx690 or 670 predator
There is a build with a Predator 670 and tsf 2221 10 gpm
Hey Jeremy do you happen to have a parts list for pump and motor and does it pull water from a buffer tank
The build list is in the description with links to the parts. It does pull water from a buffer tank
Hey J, how the machine been working for you? It’s been close to a year since you’ve assembled this beauty!!
It’s been great! I would definitely recommend it highly.
How is this combo running for you now that you’ve got some time on it? Pretty pleased with it?
This unit has far exceeded my expectations and is an absolute workhorse.
Great video. Have you noticed any issues with that pump not being supported?
I have noticed any yet, but I do plan on running a different skid plate and make a support mount for the pump.
I have bought 3 builds from envirospec over the past two years and none of them were supported, havent had any issues yet. Im looking to do a few of these set ups for back ups. on a two of our trucks we have 10gpm set ups we can run two hoses off of, and on one of the trucks we have two 6.5pm set ups each with their own engine, and we have less down time with the truck with two pressure wash engines for sure
I wouldn’t even call this a budget build. I would call this brilliant. These are great parts that make an awesome machine instead of spending loads of money. Literally almost no mechanical skills needed.
Thanks I appreciate it
What gear drive did you use between the predator 420 and the TSG6835-G pump?
I’m not sure which gear drive it is. It came assembled to the pump when I ordered it from envirospec.
Fantastic video! I have the Simpson Powershot 4400 that has the CRX 420 engine. Would the pump you used work with that engine?
It should
Did it work?
Beside this pump do, do you recommend any others pump that will work for this machine?
Anything under this 6.5 should work
Hey Jeremy, so i noticed the spacers between the pump and the engines crankcase. I wonder why they are there. Because on any gx390 or similar washer, theres no spacers. It just bolts direct, pump to engine with no issues. It just seems like a lot of risk of water or even moisture getting in, and causing absolute chaos. Or even worse SH
That’s how they said to do it 🤷🏻♂️
Do you know what the length of the 3/8 bolts you used to mount the pump was?
Honestly I cant remember
If you don’t mind me asking what exactly pump did you go with? Thanks in advance.
Allison 6.8 from envirospec. The link should be in the description.
Probably should have used some Loctite Threadlocker Blue on those bolts.
They don't come loose just keep an eye on them
Can this pull from a IBC tote well? Or do you need a 12v pump to act as a middle man?
This will pull from a ibc tote or any buffer tank you want to use
I’ve got a trailer finally. I’ve been working out of my truck bed for a year now. I’m looking at building this instead of my 4.2gpm. Is this belt driven? Or am I able to run a buffer tank if it’s not belt driven? And how would I go about doing that
This is gearbox drive it’s excellent and will pull from a buffer tank, watch the rest of the build playlist and it will show how to do the plumbing
@@KentuckyWashPros thank you!
I read where you gave the budget set up away. After working with it would you still recommend the build for us guys starting out or no? Thanks
Absolutely would recommend it. I only sold it because I bought the 8gpm off a guy going out of business for $1,200 and it was like brand new. My buddy made me a good offer on the budget build so I sold it to him.
i have a question? why did you go with the unloader to the block ? is there an unloader i can use that wouldnt require the block?
You dont have to use the unloader block, I now use quick connects on all my pump and unloader setups
Torque spec is 29 ft/lbs per Envirospec.
Good to know thanks
Hey bro, do you think the Doromax 500cc 20HP would run an 8gpm w/gearbox or would I need to go up to the 22hp engines??
I don’t think it’ll work. I’d consider getting the CRX engine
Hey Kentucky, I had another question if you didn't mind sir. Do I need to purchase the 'Valve kit, Packings and Oil seals' when purchasing the pump w/gearbox? Thanks again!
No those are only for replacement when doing a rebuild on the pump.
@@KentuckyWashPros That is great to hear. Thank you.
Looking for the same build. I've read some different accounts on what you can expect to downstream. What were you getting % wise?
This setup with a 2.1 injector I’m seeing around 1.25%
I thought there was supposed to be a felt gasket in between the gearbox and the motor to keep moisture from getting in there?
no
The new predator 459cc engine is 15.8 hp that would be much better suited for a pump with such a high flow rate.
Agree but the 459 was not an option at the time of the build
Nice how many hours can you get out of one of those Predator engines are they reliable?
This one was very reliable
Forgot to ask...How do you have the pump set up? Direct feed from hose or tank fed? If tank fed how well does it feed itself?
I currently use the predator 420 with a 4.2gpm that came with it. I want to swap it out to this pump. Do you think I will notice a difference?
You’ll notice a huge difference. And I run it from a buffer tank. It’s not setup to be used with a garden hose and I don’t think most garden hoses would keep up in my area
@@KentuckyWashPros hey so will the pressure be less without the buffer tank with both the 6gpm and 4.2 gpm?
@@corymoore4245 yes, but you almost never need anything over 2500psi
Would it be okay to share this video in some of my pressure washing groups?
Absolutely, you can share any of the videos you would like to
Got all parts except unloader. Will be breaking in the motor this weekend.
That's awesome!
How rpm ??
Do you run a surface cleaner with that set up? Is the 2500 psi effective? If so what size. Just trying to strike the right balance for the house and concrete. Considering the 15.8 unless 2500 is getting it all done. Thanks
I use a 19” whisper wash classic with this setup and it runs perfect. I do leave the unloader set at 2500 psi and it clean jus fine. I run 2503 or 25035 tips in the surface cleaner
@@KentuckyWashPros what pressure are you getting when your on the trigger of the surface cleaner ?
@@user-ek3ln1zi4j 2,500
if I ran this setup with. gx390 would I see pressure loss from the difference in hp ?
You would! Not much but it would be a little different
Are you able to pull from a buffer tank with this setup?
Yes
Perhaps this is a silly question but does the pump need to run at a specific rpm.And if so how did you address this?Thx
The pump does need to run at a certain rpm which is 1750 which is why we run a gear box
Nice video. I'm still getting my business setup, but how has this pressure washer worked for you? Has this DIY been worth the money vs. buying one?
It worked great for me. However I upgraded to an 8gpm in 2023 for my main washer. It’s definitely worth the build. I’d recommend pairing it with the predator 459, it wasn’t available when I built mine.
I think it’s worth the money to DIY it vs buying a 5.5gpm machine.
I know this is an old video but where do you get the shaft with the key? Or does it come with the motor? Can you leave a link for all the parts
it comes with the engine
there is a google doc sheet that is clickable link that will take you to the parts list with links.
How many stores can you get with that with out any Extensions
I don’t use any sort of extensions and I can clean roughly 3 stories
Would this work with a gx390 instead of the predator 420
It would work
Where’d you get the bolts to mount the engine to the plate
Lowes, any hardware store will have them. I used 4 3/8 in x 2 in with locknut’s. I also used 2 washers on each bolt.
Which pump from here for a gx340 for belt drive?
WashMart.com sells a 5.5gpm kit
If I was trying to put this build together can you list all of the parts needed and where to buy them from? Thanks.

@@KentuckyWashPros thank you so much for this it’s a huge help
@@masonpeace8824 you're welcome!
Are all these steps the same for a Predator 459cc?
Yes
Is it possible to get more than 2500 psi with this setup? Looks like a great budget pressure washer I’m considering building it if I’m able to get it to more psi for commercial cleaning purposes. Thanks for the video
You can use the Predator 459 engine and get more psi. What kind of commercial cleaning are you going to be doing
@@KentuckyWashPros I started a local pressure washing business this past year for commercial concrete cleanings and surface cleaning for drive thrus, dumpster pads and gas stations. I currently have a 3500 psi, 2.5gpm machine and it’s really nice but I’m looking go build my next one for next summer if I need a more powerful machine to get jobs done quicker.
@@salty3953 i personally don’t use more than 2,500 psi on concrete even for commercial it’s not needed 9 out of 10 times. Your GPM is really what you need for cleaning faster
Been trying to find pump but not having any luck, anybody have an idea where I can get it??
Envirospec
Wash Mart
Manatee power wash service and repair
Texas pressure wash store
How is it going man?! I built the same machine a couple of days ago with the Predator 459 instead of the 420 for PSI purpose but I was setting my unloader and for some reason I couldn’t get any more than 1000 PSI with open trigger and it spikes up to 1500 PSI on bypass. If I crank the unloader it increases the spike too much. Do you have any idea what it could be? The unloader is the VRT3
What kind and size tip are you using to set the unloader? To set it correctly you'll need a 6.5 or 7.0 (orifice size) zero degree tip (red tip) to properly set and adjust your unloader.
@@KentuckyWashPros thank you! Great to know. I will give that a try. Thanks for your help!
So this may be a stupid question but I have a pressure washer that has like 2.5 gal per min an does fine on the house what can the 6.8 pump do for me? Thank you.
The 6.8 will make washing way more efficient and faster. With a 6.8 pump I can wash a house in about 45-60 mins.
Do you use pressure when washing a house?
@@KentuckyWashPros gotcha yeah I just have a gas one its 2800 psi. So your able to wash fast with your set up.
@@KentuckyWashPros i spray the house down with just water then i apply cleaner which is bleach, dawn , an spray nine mixed then I agitate it with a brush then spray off.... i guess I am working to hard at it after watching your vids lol
What’s the update on this pump I’ve been thinking about buying ine
Pump is great but buy one again if I need it to however, I upgrade it to an 8 gallon and a 10 gallon so this to my buddy and he’s still running it
Running this setup, what was your final max PSI output?
hella
👍🏻
Hey how it holding up really interested in building one
Held up great
@@KentuckyWashPros thank just order my pump yesterday already got the motor and all the fittings gone build as soon as my pump gets here
What psi are you getting with this set up?
2500 psi
What did the zip tie do for you?
Hold the key way in place
@@KentuckyWashPros thank you
How much psi can you get with this setup
I set mine at 2,500
Would this work with a Honda gx390?
It would
@@KentuckyWashPros good deal. I have a 390 already. Just ordered everything else. Thanks for that list!
How did this rig end up working for you
Worked great for me and made me a ton of 💰💰💰
How much PSI do you get out of this???
2500 psi
How did the skid plate hold up? I see they are in stock now on Amazon
Not sure if they are in stock. It worked fine but to be honest I didn't care much for it
How much PSI does this setup produce?
I got at least 2500
Hey, first of all thanks so much for uploading the build, the specs, where everything's from, it's going to be helping me out tremendously.
Just wanted to ask how the system was still going for you? I've had buddies drop around $2000 on a GX690 saying that a Pred could never catch up to the Honda when the GX690 could last 2500 hours easily without breaking down. How many hours you've got on there?
Hoping to replicate this entire build with the 459CC and I'll let you know how it goes. Thanks so much again.
I haven’t had any issues so far with this build and it’s made me a little over 60K in a year so I can’t complain about it.
@@KentuckyWashPros Sounds good. Seems people love to bash on Predator without even trying out their systems. Love what you're doing man, keep up the great work!
the preds are better they have forged internals the Honda does not other than that they are the same
just picked up a rebrand of the predator for 350cad (260 usd). i can buy three of these for the price of one gx290 (1200cad). if the motor only lasts one year, who cares? just buy a new one.
@@aidenlee5207 iv ran the predator 420 with 5gpm pump for 3 years and have yet to have any issue
At $1,700 almost in parts i wouldn't call it budget lol. Im sure its a good savings compared to one readymade with similarly parameters
Well it’s counterpart which is offered as a 5.5gpm will cost you around 2,200-2,500 so I would classify this as a budget build.
Why do you need the spacer?
it calls for it
What pump is that?
envirospec.com/buildcart.cfm?pn=TSG6835-G
Hey sir I know it’s been a year that you made this video?can this pull form a water tank
Yes it can pull from a tank
@@KentuckyWashPros thank you for responding
Whats the difference between this build and the Texas Pressure Washing build created by Heath Phelps?
No real big difference
@@KentuckyWashPros is there any difference at all? Or are you just sort of relaying the build with your own experience with it? l always felt thats what was lacking from Texas Pressure Wash. Your videos actually show this equipment in use. And are you still having issues with the predator 670 fuel pump? I've heard from many sources it's complete trash and should be replaced. My big question is how is the ar30? Seeing it in action on your channel made me want to order one today
@@ctbulldogs3518 I built my budget build from Heaths parts list but at the time there wasn’t really an in depth build video, so I decided to make one. The only thing that may be different is the links I needed up getting nearly all my stuff from PWP. I think at the time there were only a handful of people running these builds and not a whole lot of experience with or info on them.
I am still having issues with the 670, I have switched the fuel pump out once and not luck with that and I am about to switch it out again this time with a Mikuni fuel pump and if necessary I’m going to add a low pressure 12v fuel pump. I believe that it could partially the fuel tank causing the issues as well. The 670 has moments that it runs great when it is getting enough fuel.
The AR 30 is a beast, I love it and would recommend anyone to build one.
@@KentuckyWashPros what fuel pump did you originally use as a replacement? I've seen some people say use the gx690 fuel pump
@@ctbulldogs3518 That's for the 670 not the 420
What pump is that
Allison 6.8
envirospec.com/buildcart.cfm?pn=TSG6835-G
What’s is the Psi of the pump?
2,500
Why is your list completely different from what you built. Did you rebuild everything?
A link to the google sheet build list to this is in the top of the description.
How much was pump?
There’s a build sheet in the description with links to the pump
Is there a reason you are building off a 420 engine and on the google doc list it is a 459?
This build video was made before the production of the 459 engines. Have tried to keep the build sheet updated, if I were to build this now, I would use and I recommend using the 459
Always recommend electric start!
That pump recommends 18-22 hp
Pump works perfectly fine on this engine. You will get close to 6-6.5gpm and 2,500 psi
Do you still use this setup
I don’t, I now run a 8 & 10 gpm washer
@@KentuckyWashPros I will be starting out in the spring. Thing about building one. I have a 4 gpm now.
Engine hours and clock hours are not the same...if the hour meter and your time are the same...the hour meter is not correct.
I don't think you heard correctly. I set a timer for 3 hours when I started the engine for the break-in process. I shut off the engine at 3 hours and my timer went off. The hour meter matched the timer that I set. So if the hour meter would have run differently than the timer, then it would be a faulty hour meter and not worth using....Not sure what kind of point you're trying to make.
@@KentuckyWashPros IF the hour meter said 3 hours and the timer said 3 hours...the hour meter is incorrect. Engines hours and clocks are not the same.. If you work for 1 hour by your watch/timer...a proper hour meter will show less than 1 hours...engine hours and clock hours are NOT the same. They are pretty close...but NOT the same.
@@jimmywarren6685 what? 😂
@@jimmywarren6685 are you talking about engine revolution? motors clock time by revolution, still doesn't mean that 3 hours run time isn't 3 hours.
@@TakinBumpsNBlownScales My only point was that engine time is not measure like clock time...so, if an true hour meter hours match the hours when compared to your watch or kitchen timer...the hour meter is not giving the correct engine hours....so don't say that it is accurate because it is not.
the machine will get 5.5 gpm max because that engine isn't strong enough to get 6-6.5 gpm.
I’m seeing 6.5gpm at 2500 psi
@@KentuckyWashPros I’m looking right at the machine and this machine does not pump 6.5 GPM.
Lots of guys in the industry run this setup and get 6 gpm all day long
@@platinumhawkpw lots of guys also bs and Overexaggerate specs
I have a GP 5.5gpm gear drive pump on a gx390. I see 6.5gpm at 2300psi all day long. Simple bucket test. Great for house washing….cleans concrete pretty good as well.
Would this same pump and gearbox work good with the predator 459cc?
It will
@@KentuckyWashPros thank you sir
