Hello all,
I have a hydraulic pump that is perfect for a fel project I am doing except it turns the wrong way. I took it apart and it seems like I can flip everything around . It has front and back plates, a center housing and a center gear cluster If I flip the center housing and gear cluster around will it pump? I am no hydraulic expert . :dunno:

It turns CCW that is the problem . The tractor is a 73 MTD 990 , I want to use the pulleys on the flywheel side. I have the pump and want to use it if I can . I can just turn it around and mount it low , but it is really to far down for me to feel good about . If I can reverse it , I think It would work out better.

Mike ,
That is option two. I would really like to mount this pump directly off the front shaft with a lovejoy coupler . To do this I need to turn CW . If I cant I will mount it oppisite the starter/ gen and run a belt. Are you using your pump to turn your blade ?

Mike ,
I read that wrong. The rear of thre engine already has the driveshaft and the rear PTO for the deck . The space is limited. If I have to belt mount it , the front is the better option.

It is a gear pump .
Mike ,
that is exactly what I am looking to do. I am going to reverse the pump and do some tests with a gauge and deadhead the pump . See what blows up!

Not to late yet. So how do I test it before going through all the trouble to mount it . If I can move oil from one bucket to another at a good rate can I assume it will build pressure ? Would pictures of the pump help decide if it can be reversed?
