is it possible?

[scott2432003]

just curious if anyone has ever heard of anyone turning their truck into an ultimate utility truck with hydraulics for a snow blower, backhoe attachments, towable log splitter and what not if that is at all possible im interested i have a 1989 f-350 with a 460.... can it be done or is it a pipe dream?

Welcome to the forum.

Just might be. What else is in this dream? Can you give a better picture of what you envision? Big hyd. pump on the 460 engine? Then what....and why? And for what kind of budget might we need to follow?

Give us more to go on...thanks

Toughest part would be to build that high power PTO.....almost easier to just build a new complete power unit with engine and everything.....on the bed or towable...

Also a pump for a snow blower would need constant high rpm's from the engine, and at the same time the engine is serving the drive transmission on the truck....

Using the same engine for high powered attachment, like snow blower, and drive transmission, will put a hydrostatic drive transmission on top of your SANTA wishlist.....

Look at all the 1500$+ lawn mowers .....there is a reason all of them have hydrostatic drives......

The old willy's were used like farm machines, they had PTO etc.

To produce 20 GPM's, at 3000 psi from the main engine, or a separate engine, requires about 41 HP. 30 GPM's requires about 62 HP. This clutch pump will pump 20 GPM's at 2200 psi.

Yes, I believe you could make yourself a power wagon/transporter out of that F-350.

So you want to turn a F350 into a UNIMOG?

Might be easier to fund a used AG Mog.

yeah i dont really have a budget in mind. just thinking that if i completely restore this truck and put exactly what i want back into it it would be great to have a hydraulic system that could power a snowblower, backhoe attachments, post hole digger, basically anything out there hydraulic. i would like to do it without the extra engine if possible. the bucket truck i work on kicks up the rpms when kicking on the pto. we have hydraulic chainsaws, jackhammers, and drills also the digger trucks we have got augers that dig up to 24" diameter holes for poles. i know my F-350 is alot smaller then those trucks but just curious what would have to be done to get the powerfull hydraulic system in there neatly hidden for when i needed it.

I know of a fellow who has a commercial pecan orchard in Navarro County and he made his own tree shaker to shake the pecans out of the trees. I've seen it but don't remember a lot of details. I just know it's the chassis and engine of an old International pickup truck. So I would assume you could do something like you ask about.

The clutch pump I mention above is the answer. Nothing showing. Tank/reservoir and hyd cooler can be hidden under the truck body.

I only have 13 GPM off my hyd PTO, and I can dig a 30 in hole, run a 72 in tiller, 72 in flail, stump grinder, just about anything hyd . The 13 GPM at 3000 at the motor develops about 23 HP. A larger pump feeding a larger motor, will develop more HP.

thanks for the advice on the clutch pump the last question i have is can i up the size of the pump to get the gpm i would need at slower speeds/lower rpm's for a snow blower or would i need the hydrostatic drive transmission to make it work the best?

The snow blower would need constand high rpm's to work.....can you move a stick shift or automatic transmission pick up truck, safely on constant high rpm's???

There are lots of pumps out there that will produce 50 GPM or more, but the clutch pumps I have seen go up to about 21 GPM. Both Northern and Surplus Hydraulics have them. Here is a link to the clutch itself.

Ogura Industrial Corp. - Products

There may be a chance of running two pumps is parallel to give double the output. Perhaps AKKAMAAN can verify if one can take the output from two pumps and produce a larger flow without problems. Otherwise, two pumps having common intake manifold, and combining the output of the two pumps into a common manifold. Two 21 GPM clutch pumps producing a total of 42 GPM.

On the hydrostatic transmission thing, I think what AKKAMAAN is saying, is that you would have to be in a low gear for snow blowing, and therefore the engine has to be turning high rpm to produce the max output from the clutch pump. Using D1 or low gear, will keep the engine rpm high. However, if the pulley ratio could be changed to give high volume with slow engine speed, then that might work. I know garbage trucks and cement trucks have large pumps on the front of the trucks for whatever. Those pumps might be direct drive.

Generally speaking that is not a problem....many open center systems do have multiple pumps of different reasons....but for cost efficiancy, 1 large is usually cheaper than two small....

Is this different than the quote above???

Even if you are in low gear, you might have to vary the vehicle speed with the "gas" pedal (rpm's)....I just do not think it would be either efficient or safe....But sure it would blow snow....

An option would be using a, more expensive, pressure compensated variable displacement pump, in a closed center system,.....that pump would need to be a little over sized to make necessary flow on low rpms.....just make sure there is enough engine torque output at low rpm's for both blower and travel.....

 

[scott2432003]

Thanks for the input. Ill probably be asking a few more ?'S when I get to this part in the rebuild

 

[mmurphy]

Scott, I am not totaly sure of this but, it seems to me if you know some one that really knows automatic transmissions the valve body could be altered to the point of reducing flow to the torque converter and or you could go with a higher stall torqe converter that will allow engine higher rev before driving transmission. I will try to locate a guy that rebuilds trannys to see if that is feasible. If that is the case I cant wait to see the build what ever way you go.

Go find a state truck with a plow and a sander. I installed live hydraulics on an F-700 by running a pump off the front of the crankshaft. This thing runs a dump body, main and wing plow, and a sander. A pump off the front of the crank gives you all the hyd gpm and psi you will need. And, I have seen those huge snowblowers on the big state trucks. So, what you want to do is definately realistic. I say go for it. The world hates a coward.
