wet kit pump set up

First is it a gear, variable/ fixed displacement piston, or a vane hydraulic pump? Next a few pictures will really help. What loader, barco, prentice, hood, rotobec, serco? What trans, and pto? If its a gear pump its easy to tell the direction of flow. To change the flow direction on a gear pump you just flip the gear section of the pump. Is the filter in the tank plugged, that would restrict the flow also. The more pictures the better. I have had 8 different loaders on tri axles and trailers over the years, put them together myself, so its easy to figure out with enough information on your side.

 

The top of that PTO shaft needs to be turning towards the passenger side of the truck. Is it going that way? It is a gear pump. The center section that the hoses go into is just a bearing carrier. The two sections in front and behind the center are where the "gears" are that are the pump.

 

If it was going in the wrong direction I would think it would make some bubbling in the oil tank but most serco loaders Im around have the tank mounted in the a frame so you should be able to see s set of gears in there turn shaft by hand and see what way the gears are going the pump, on my truck is set up the same way it is a rotabec but same thing in a nutshell good luck do you have shut off valves on the suction? If you was to have them closed it can crack a pump section I have saw that a few times just dumb stuff to check I have drove logtruck for 22 yrs and I see and hear of different things all the time you never know with these things .

 

Give Permco a call and see if it the housing can be rotated 180 degrees to change rotation. I've never used a Permco, but for many other pumps, it just a matter of rotating housing. Then you'll just have to rotate the whole pump 180 degrees to get your ports back in the same location. In your case, you may have to rework that rear bracket, since you pump is offset upward right now. If you can change it to reverse the rotation, it will be offset downward.

 

What way does the shaft spin now? We still dont know if its going the right or wrong way. It could be the pump is junk and needs to be rebuilt. Also if you look at the shaft on the PTO (as if you were going to jam it in your eye), and it rotates CW. Then look at the pump shaft(in the same way) and it spins CCW it is rotating correctly. It is as a mirror reflection would be, you observe the shaft as it comes out of the housing it is in. Which way does the top of the shaft spin?
