Our first was a manufacturer built set up.....the unit we're working on right now is going to be custom built by Roger

We kind of build our own but what we really do is buy components that we think will do the job that we want done and then assemble them.
We are just now putting the finishing touches on the upgrade of the unit in our White truck.
The picture shows a 48 Hp Kubota liquid cooled diesel engine that we are going to run a General TSF-2221 and a Winco 8,000 watt generator.
We should have this unit completed and running by the end of this week.

Dave is that a 28 hp or a 48 hp? I have some Kabota parts left over like oil/air filters I want to unload. We custom build ours from the ground up using a PTO so everything runs off of the trucks' diesel engine. 99.99999% reliable.

Hello Eric,
I'll keep your parts in mind. It is a 48 hp engine.

Nice set up Dave
I kinda figured others were doing some sort of customizing. Seems to be much more econonmical to build your own unit. I got a line on some 25hp water cooled diesels electric start for $600 each. TS2021 for $450 and you got a decent unit for the cost of a home depot throw-away.
To think I paid $8000 for my Landa SGHW 6-3500. No more of that noise. Don't get me wrong, it is a sweet unit wit 24hp Onan and all, just way too expensive for the Name brand.
North Coast, good idea with that PTO. Now your truck does more than just get your rig to and from.

Nice! What size pump(s) are you using?

Thanks guys, we hope it will serve us for many years to come.
That is a General TSF 2221 (10.2 gpm) and a 8000 watt Winco generator.

Built all custom units.Buy the components seperately and rig em up how you want.
Ive combined everything from 1 million btu boilers and 14gpm pumps for hydro vac trucks, down to 4 gpm and 4 hundred thousand btu boilers for trailer wash units.
Options for driving them are endless.Gas motors,deasel motors,pto belt driven, pto hydrailic driven.
boiler power 12 volt,11 volt, generators and 12 volt invertors.
In northern climates where the truck runs anyway while at the jobsite, pto is the way to go.Either hydraulic pump and motor or belt driven from pto shaft(cheaper). This eliminates the need for the additional expense of a auxillary engine.
Warmer climates where you shut down the truck at the job use an auxillary engine.
Either system if your boiler is 110 volt I prefer the invertor to power the bolier as it is a cleaner power source as compared to the driven power generators.Less varince in power fluctuation due to changes of rpm and about the same or less that a generator.Driven generators can be hard on electrical components if spun to fast causing spikes in power thus hard on transformers and thermostat controls on the 110 volt boiler units.
The factory units are OK for the starter but the custom assembled unit allows way better options for temperature,pressure and plumbimg of the system to suit your individual needs.
Definately not rocket science just takes a little xperience and testing.
The biggest advantage to custom buliding your unit is for easy diagnosis of breakdowns and parts sourcing.most breakdowns on my units can be diagnosed within minutes easily and fixed at location if the spare parts are handy.
Soap injection,winterizing tanks,steam production including dry steam kits, line jetting and pre spray chemical application can all be custom built and assembled if you research a little, and definately better than over the counter units in most cases.

I have a hydrotek skid unit on one vehicle and i built the 5.6 gallon per minute cold unit for my other vehicle. It works well... 20 hp kohler - 2021 pump - k7 ect.
We usually buy a standard unit and change a lot of things over to suit our needs, ie K7 bypass, new engine and pump mounts...... Looking at building from scratch with a diesel engine. Most standard units over here use either a 15 or 20hp Honda engine, but with the way fuel prices are going it seems more economical to shift to diesel.
My question is, do I direct drive the pump or use a gear box? I noticed that Dave has a direct belt drive, and I am curious as to how they run (in regards to wear & tear, what size pullys to work with) Pretty much the gear box is standard over here and everyone is fearful of belt drive for some reason, though I am thinking about running a direct drive using a 'spider' coupling.
I would appreciate everyones thoughts as I am in the 'ideas & research' phase of the project and would like to start building in the next 3-4 months.

Don't know if anyone would be interested in watching the build of our new 06 Kenworth T-300. We build everything from the ground up in house, takes about 8-10 weeks. The only part we outsource is the powder coating and the manufacturing of the prop shaft.
