PTO hydraulic pump from dump truck

[PHPaul]

Need shafts and pump for a PTO driven hydraulic pump as used on dump truck kits.  1:25 scale.

Doesn't need to be exactly like this one as it's being retro-fitted to non-dump truck tractor to power a knuckle boom crane.

Look to the 3D printed parts industry.... somewhere I've seen seen U-joints printed, then "add" the tubing/ old sprue ...the pump looks pretty basic to scratch build.

Yes, I actually drew the pump up and printed it out.  I'll look and see what's out there for u-joints.

Thanks!

EDIT:  My 3D printer (Creality Ender 3) won't print u joints small enough.  Larger ones like for a driveshaft are doable, but the pump shaft joints are about 2mm wide and it won't print that small.  Not enough plate contact area.  Possibly with a raft but then I'd likely destroy the print separating it from the raft.

I'm not sure of which kits, but some have a part to represent the steering box........ That's kind of what that looks like to me! Some of those should be molded with U-joints........

Maybe someone knows what kits have that part?

do you have any vw bug kits in the stash? they'll have 4 for the drive shafts

The winch is like 20 bucks but it has the pto and box and drive shafts. He has driveshafts and u joints too. If you find something sold out keep looking, he probably has another one just like it on a different page. You just have to search. And if it says out of stock, e mail him anyways. He may have it or can get it for you quick.
