NAA Vane pump

Is it true that there are no rebuild parts for this pump ? New piston pump is just a little expensive \sarc. Is there a way to tell what the pressure of a vane type pump is ? I don't even want to think of replacing it unless there is a used piston one out there. Something about a manifold change too.

Manual for specification & measure it for what yours actually produces.

Fear not; TOH has the perfect solution that you can purchase from him and the expertise is free. :)
 
(quoted from post at 12:51:52 04/27/18) So I see. 1750-2K

Where is a port to install a gauge ?
n the right side of the hyd compartment , near running board. You need to block flow as per instructions in manual or else flow is just bypassing without much restriction, thus not much pressure. If system is working this can be accomplished by chaining lift arms down and commanding lift.

Replacement vane and rotor kits with ring have recently shown up on the aftermarket - roughly $380. I have no experience with them.

You can pressure test the pump by chaining the lift arms down but that does not isolate the pump from the lift components. A better method is to remove the block off plate on the top cover and reinstall it rotated so that it blocks off delivery off pressurized oil to the lift. That way you are testing just the pump and over pressure safety relief valve.

Two Oaks,

Being as you've been on this forum for so long you probably know about this, but just in case . . .

Infinitely safer than an aftermarket product I would bet.

Thank you Tall T

I've been in conversation with Dan @ WRF. I'll probably go that route. Thanks again for the tip.

Could you post a link to the vane pump page? I can't open that page using a tablet. I have to hold my finger on the products to get the window to open, when I remove my finger the window closes.*sigh*

Dan, does this method work for 00/01 series tractors too?

Ahh yes - the beauty of touch screens and "HTML/CSS standards" developed with "mouse events" in mind. I guess I will have to look into this - the menu doesn't work correctly on my smartphone (IE/EDGE) either. In any event (no pun intended) here is a direct link to that page:

Actually it works on the Hundreds (+ early Thousands) and does not work on the NAA. Here is a picture (courtesy of JMOR) illustrating the process which is also described in the FO-20. When I get to the shop later today I will try to puzzle out a way to accomplish the same on the NAA. As shown in Jesse's pictures the re-postioned cover blocks off incoming oil flow and eliminates all hydraulic components except the pump and over pressure relief valve from the circuit under test.

As I said in a previous response I would find a way similar to the one used on the Hundred series to isolate the NAA pump for pressure testing. Here it is. Remove the block off plate from the top of the hydraulic cover and use a 3/8-18 tap to thread the pressure inlet port. The port is a little larger than the normal 5/16 tap drill size which makes it very easy to tap. Then blow out the swarf, coat the threads of a 3/8-16 x 1/2" socket head set screw with sealant, and install in the port running it in until it bottoms in the port and is below the face of the block off plate. Reinstall the plate and you have isolated the pump and relief valve from the 3pt lift and can get a good reliable pump pressure reading. I have not actually tried this but I see no reason it won't work. After your pressure test simply remove the set screw, blow out the cover just to be safe, reinstall, and your 3pt is back in normal operation.

PS> I only had a 3/8-24 set screw so I could only start it into the hole to illustrate the process.
