The mark on the wear ring would reduce the flow, not remove all flow like you are having.
I checked last night and there was an arrow. I had it installed the right way to begin with.
That is possible...... You can really only go step by step and hopefully find what is wrong/missing.
Troubleshooting this vane pump. When I started to reassemble it something just don't look right. The shaft that spins the rotor is sitting only halfway in the rotor. And the plate looks as if it has a bronze bushing in it. Anyone know if there is supposed to be a shaft that goes in both the rotor and the plate? I can't think of why there would be a bronze bushing in there if it didn't have a shaft to support.
Wish I knew more or could see it from here but think your on to something
It occurred to me that someone might have sawed off the end of the shaft. I could imagine the shaft would go all the way through and the end would be turned down on the lathe to fit the bronze bearing. If for some reason the previous owner sawed off the shaft it would look like it does now. I hope not.
That is very odd, the shaft should go all the way through and be supported by the bronze bushing on the end plate. Could the end have been broken off?
Any idea where I can get a replacement shaft? Bobcat parts online show it as no longer available. I'm checking sewlparts.com but would like to know of any other sources for used parts.
Talk to loader parts source, they can generally get anything hydraulic, they may be able to get one for you at a good price. That or confirm if something is indeed missing or not.
No luck with Loader Parts Source. They will sell only the pump. I need something second hand.
That isn't much help at all, they have always been really good with parts.
I may have found a shaft for this pump. I've found a few between $58 and $75. Its just a matter of finding the right one.
I'd take measurements and hopefully find the correct one. Same spline number and shaft diameter at the end. There is a bearing there, so you know what it should be.
Got a voice mail from Loader Parts Source. Pete was responding to my email. A couple of days earlier I I spoke with a different person when I called Loader Parts Source so I took a chance and called Pete. This guy provided unreal customer service. I emailed him the pictures that I posted in this thread. Pete went to the service area and verified the splined shaft was supposed to go all the way through the vane pump rotor and was supported by the bronze bushing. Comparing what he found to my pictures, my pump shaft was broken and I needed a new one. They had the shaft in stock and could ship it out today. Unreal huh? The guy I talked to before said they didn't have the shaft and only had the complete pump. I bought the shaft for $150 and Loader Parts Source will be the first place I go for parts.
Good to hear they have allways been good to me you just got the lazy one the first time
Now that's the service i have come to know and rely on that they provide.
Update to the no charge problem. It turns out the rotating groups were put together wrong. Yeah. I did it. I should have went by the diagrams but missed it. I put them back together the way I found the right drive motor, which probably explains why the right motor never worked, and then broke into several pieces. I assembled the rotating groups correctly and noticed that I could not longer push the bobcat by hand. The wheels were locked up like they were supposed to be. The rotating groups have a preload on them pushing against the swash plates and the rear drive housing inside the drive motors. I have a gauge right above the filter and when I fired up the engine it took a minute but the charge pressure went up. I operated the foot pedals and the lift and tilt worked right. Then the big test. Would it move on its own? It did. You can't imagine how much I appreciated that. Then the right pedal stuck and the vane pump started growling. Apparently the valve is stuck and not letting the fluid circulate. At least the hard part is over.
