A non tractor question. It's about my pickup.

....but it is about accessories and attachments.

I've recently purchased a Chevy Work Truck. 160,000mi v6 4.3 liter manual trans w/o air. Never had a pickup before. I love this simple red truck. One of those "how did I get by without this?... sort of things. I live on two acres of property, semi residential. Never had a purpose for a tractor. I heat with wood during the winter.

It's actually most practical and cost effective to have wood delivered, but I just can't help myself for tinkering and diy. So bear with me a sec. And right off the bat, I'll stress that I am NOT GOING TO DO ANY OF THIS. It's just an idea I'm intruiged with and am interested in your thoughts.

Last time I was under the hood of the truck, marvelling at the wealth of open space, I began to wonder why more guys don't just bolt stuff on to these older pickups (no room in the newer ones) such as hydraulic pumps, pressurewasher pumps, welding generators, etc. I can get one heck of a nice 400 dollar (w/20 percent off coupon) PTO log splitter to bolt on to the bumper of this Chevy and run the hydraulics off of the V6.


More splitter for the money. (raw two stage 11gpm pump is 150 dollars and I'm capable of putting together the reservoir, tubing, and valving). No need to pay for and maintain an 8hp Honda. The above PTO splitter comes complete with hyd controls. It's HF. But it's bone simple stuff. It breaks. I fix it.

Splitter takes up less room to store when not in use.

No need to trailer anything. Splitter would be carried to site in bed and mounted to the rear bumper when there. Or even hinged to the rear bumper and raised and lowered with the gate.

Much quieter. Fuel inj V6 at idle would be sufficient HP/torque and use not much more fuel than an eight horse air cooled single.

Toss splits right in the bed as you work.


I don't know what sort of safety lockouts tractors have when using PTO implements (implements, like splitters and post drivers that require you to be out of the saddle if working alone) but this might be harder to safegaurd using a pickup. Truck would have to stay in neutral and wheels locked even beyond simply using the emergency brake.

Pump could not be run over it's design rpm. It could be belted via 12vdc clutch, but the first time it was accidentally engaged at highway speed it would be destroyed. Better to just keep a timing belt under the seat of the truck and simply install it when the pump is needed. Quick and simple.

Just some thoughts. Ever seen or heard of this type of thing?

welcome ...I guess......As you must know, this is a tractor forum.....Don't want to sound rude, but why wouldn't you go to a truck forum with this?

Anyways, good to have you aboard...we will just have to convince you that tractors are just as much fun as your truck......LOL
Sounds like some new fresh idea's. That would be pretty cool if someone would make something like that.
Welcome to the forum. Interesting ideas. Keep 'em coming.

Yeah, it's mainly a tractor forum, but there is also a "non tractor" section, even one for Trucks. Maybe one of the moderators can relocate your post to the Truck forum if you request it.

But I see your point that this is sort of a tractor-ish kind of question (the PTO part at least) as much as it is a truck question.

Also I see postings all the time in the Snow Removal forum that a simple pickup truck with a plow is faster and more comfortable than using a tractor with a cab and all the complexity of getting it to be warm, using wipers, having good visibility, etc.

Trucks. The Tractor's 2nd cousin, once removed.

Actually, I posted this in three separate GMC/Chevy pickup truck forums. Basically got a lot of "not worth the effort". "too much work". "why the **** would you want to do that?"

Actually those aren't unreasonable responses. I was just hoping to find someone of like mind who might have done this. Tractor owners are more likely to be self sufficient homesteader types than "truck enthusiasts" are generally.

Heck, if I'd posted on one of those truck forums asking how to rig up onboard hydraulics with cylinders at all four wheels so that I could cruise the blvd and make my truck bounce up and down with a dash mounted lever I'd have all sort of "how cool. Let's see ya do it". I'd probably get more thumbs-up encouragment and advice than I could possible use with that sort of question. There are no doubt (shudder) online vendors that I'd be directed to that could provide a wide assortment of hydraulic bouncing truck accessories. But I want to rig up something to split wood to heat my home? "why the **** would you want to do that?"

The things that people consider a good use of inventive talent and wrenching time often astonish and depresses me.

personally i think it'd be a good idea, i have a buddy that could use something like that. any way what pressure does the splitter run on? would a second power steering pump produce enough pressure. just a thought.
A power steering pump would have enough pressure but it would be slow, the pump is relatively small for operating a larger cylinder.
I think it would be a good idea with a couple of caviats:

1: Running a pump with a 4.3 you would have more than ample power. The purpose of a two stage pump is to give you high flow/low pressure when you need speed as in coming up to the wood or retracting and high pressure/low flow when you're actually splitting. Any two stage pump I've seen are made to be direct coupled to a small engine so they're made to run at a high rpm around 3500 or so.
That being said, I'd go with a standard 10-14 gpm gear pump, why get something you don't need. Only thing you'd have to watch size wise is not getting too big, then you have to worry about belt slip. RPM could be set via sheave size.
A real slick setup would be a drive right off the front of the harmonic balancer but then you'd have to get into coupling/uncoupling setups.

2: Since you don't have air you've already got the space for the pump, all you need is the clutch setup.

3:Wear on your engine, carboning up would be an issue I would think. probably work like crap after until you blow the garbage out of it.

4:As for lockouts, you could connect a kill switch to the ignition and have it removable via a plug and mount the actual hit switch somewhere accessable at the rear of the truck. It would be no more dangerous than an actual woodsplitter IMHO

The Harbor Freight PTO splitter above has a cylinder sized 4 inch bore x 24 inch stroke. Hopefully a two inch shaft. 2400 psi rating.

The two stage Haldex brand "log splitter" pump below seems a good fit.

Or you could even save forty bucks and get the made-in-china version on the same page.

But would the 13 gpm version for 179 dollars (since flow rate is ultimately determined by rpm it can be run not to exceed 11gpm) be a better choice?
In other words, at 11gpm are the 11gpm and 13gpm pumps providing essentially the same flow/pressure/recoverability/stage switching characteristics? These are the kinds of things I'm hoping you guys will know.

12vdc clutch would be a good idea, except for that danger I mentioned of overrunning the 4000rpm spec limit on the pump. I'm guessing that a power steering pump must be built to deal with the much broader range of rpms it will see in service. I know that log splitting pumps are mated gear pumps. Power steering pumps might be sliding vane pumps. They'd handle the higher rrpm but are rated about 30 percent of the needs for a splitter. And I could be wrong on all of this. Any hydraulics gurus out there?

I'm actually suprised that there aren't bolt on pressure washer kits available for pickup trucks. If there are, I haven't found them yet. Once again, you could get triple the pressure washer for the same amount of money if you could order it without the engine. Most of us are certainly competent enough to bolt a pressure washer pump to a truck engine especially if it came as a kit with clutch and belts and fittings, etc.

Voila! 4GPM @5000 psi. What otherwise pushes such a powerful washer into the four to five thousand dollar range is quite a big engine. And there's a perfectly good one in your old pickup. Bolted under the hood of the truck you've got electric start, super quiet, no trailer, no extra maintenance of another engine. And you can get groceries with your new pressure washer. The kit could even include a pressure regulated throttle advance to tie into the trucks throttle cable, that's actually a pretty simple unit.

It can, and has been done. A lot of wreckers, and other trucks run a pump off of the tranny PTO. No reason you cant belt drive it though. I would put a clutch on it though. Like a AC pump. Just so it will not keep pumping wile you use the truck.

A lot of the Fourwheelers hoop up the old York style AC compressures and turn them into compressures. Add a tank, and some pluming and your good to go.

I did not see the category for "full sized" tractors and accessories.
I wonder if that might be a more appropriate place for this post?
Maybe more experience with hydraulics.
With respect, would a moderator switch it over to that section if this is the case?

Thanks so much.

This is what will happen to your truck... After a while you wont be able to tell its a truck...

Kevin, you DO have one of everything, don't you! Actually, probably more than one...

If there's ever a great flood, we'll be able to reconstruct mechanized civilization just from your collection...

Northern Tool has a belt driven pump with electric clutch.
I have installed such a pump on a '76 F 250 4x4 to run
a bail fork .
sounds like a neat idea, though i honestly don't know how feasible it is. i would love to have an easily accessible splitter. even if you made it on a trailer you could put couplings at the bumper to plug it up.

Your post is just fine here. You are talking about a pickup truck, and this is the truck forum.

I have a couple of friends who have PTO operated hydraulic pumps. One of them needs it to run a 35' trailer that tilts and has a winch on the front of it. The other is a farmer, and he uses his truck to move equipment around between his farms when needed. Both guys have reservoirs on board, and pioneer couplings near the rear of the box. One of them has the pump mounted on the transfer case, so he has a 4 speed pump. That comes in real handy when winching a light load on to the trailer... you can run the pto in 4th gear and really speed up the winch.

Not sure how efficient it is to run a big engine for 4 or 5 hours splitting wood when a 5 HP motor would do, but it would be one less engine to take care of!

Good luck on the project and :Welcome1:

I saw the clutch pumps at NorthernTool. I've seen a few other places that offer same. In fact, (my favorite) has them as well. But since this add on would be used (for me) exclusively for splitting, I'd be better off (i believe) with a more dedicated two stage "log splitter" pump like the one I linked to. Also, I can get that pump and a 12vdc clutch for a little over 200 dollars. The ready to go clutch pumps are all more than twice that.

As I mentioned. I am not going to actually do this. Ok, I MIGHT do this. But the bottom line is that my motivation less than half practical. The main part of it is the entirely impractical love of DIY and using something you built yourself. I think there are a lot of guys out there that know exactly what I'm talking about. The satisfaction and enjoyment of doing any chore is tripled when you're actually getting it done with something you planned, welded, wired, plumbed, etc, with your own mind and hands.

I don't even intend ever selling firewood. I might use it once a week for only two or three hours each. Why the **** would I go to the trouble of integrating a splitter into my pickup truck engine and tailgate? Well for one, I can put together a 2000 dollar level splitter for less than 700 dollars. But for anyone else who understands the DIY mentality, the answer is obvious. This stuff is as much fun to think through and do as it is for the next guy to build a dune buggy and scoot around in the sand all afternoon. Or another guy to build a racing car to haul to the track on weekends. I applaud those guy's interests. But people seldom wonder aloud to them about why they spend such time and money (except their wives perhaps). I just find it bizarre when others ask me "what the **** would you want to waste your time on that for? Just buy one". Why don't they understand? I'm pretty sure many of you do.

I think it;s a good idea, mabey have it hooked to a trailer hitch? I would have 2 switches to enguage the clutch. a On/off with a cover and then another one hidden somewhere that it wont in advertantly get turned on, mabey have that one out in the bed of the truck, under a rail, so you can turn it on or off while standing out back working.

oh and with a belt drive, you could try differnt pullys on the pump to get the right rpm.
