Okay, I have a 96' 3500 dumper, It currently has electric/hydraulic but I want a live floor in the bed and was hoping to run the hydraulic motor and the dump piston off of a hydraulic pump hooked up to the pto on my tranny. But let's face it, its never gonna happen. How much is it going to cost to hook up a pump to my pto? Looks expensive! Is there a take off part from another vehicle that I may be able to find? I'm thinking an engine mounted pump would be more realistic. Like a Fisher engine mounted plow pump or maybe even an old power steering pump??? Worst case, I'll just hook up a 5hp Honda motor to the live floor.

 

cant you use a wood splitter hydralic pump?

find out how many rpm the pto runs at, then you can find the pump. this will work but it will probably be slow. maybe they list a gear reduction style pump?

 

Thanks anyways but, I'm not sure you know what the pto looks like. There's no protrusion, no shaft, nothing. There's only a sheet metal cover plate on the transfer case. What is required almost looks like a small transfer case that has a gear sticking out of it which then meshes with the gears inside the transfer case and converts that into an external pto shaft or mounting provision for a hydraulic pump.

 

you got it.

 

You'd be surprised how cheap and easily available a pto gearbox unit is.
There are basically only two types, a eight bolt and six bolt. The direction you want it to turn is determined by which side of the tranny it's mounted to.
I've come up with several pto drives over the years from truck junkyards, never paid over $50.

 

there are several ratios in the ptos. i found out the hard way. bought a new one for my ford conversion. they ask me what % ratio did i want. i said 100%. oops. raises the dump REAL fast at idle. do not raise engine speed on this one something will break.

 

Isn't the speed of the PTO drive different on each side of the transmission as well?

 

Does the pto run all the time? I'd like to run my hydroseeder hydraulics off of it, possibly.

 

No, there is a cable that you pull to engage the PTO. If you were trying to run the hydraulics off of it while the truck is in motion, you would need to do some pretty careful matching to make sure that the PTO was running at the right speed for the hydraulics while the truck was moving at whatever speed it needs to move at.
