Live Hydraulic Pumps

JD offered their tractors with an optional hyd. rockshaft that was driven with a pump built into the pto so your pto had to run to operate this and at that time the pto was not live. Or your tractor may of not had one of these it may have a pto only. If you had the hyd. rockshaft (most popular of the first uses was to lift up a mounted cultivator)and you wanted it to work LIVE as not to run the pto then they offered this kit. The complete list of parts is shown in the parts books for the A,B and I bet the G models. The pump went between the gov. and the mag. or dist. then hoses ran back into your existing hyd. valve and rockshaft housing. You also needed to remove the idler gear in your pto hyd. pump and also add that block off plate between your valve housing and the rockshaft housing this is where you need 2 gaskets 1 on each side of that plate.

Of course many a farmer /inventer bought just the pump only and hooked them up to their own homemade reserviors and plumbed in a seperate valve theirself etc. They could of ran any number of things some ran loaders,I've seen some hooked up to add on powersteering units. I've also seen hyd. pumps ran off the fanshaft and or flywheel.

Another way to convert yours to outlets is to buy the valve box part from a later B with power-trol from ser# 201,000 and up. Then it's just a matter of unbolting and switching your box out for the other one. Many were done this way. No other modification needed. I see these on e-bay or check your local junk yard.

The late B valve box will give you a place to hook up quick couplers for a remote cylinder and also the ability to raise and lower and stop the rockshaft or cyl. at any position. The pedal lift only lets you go full up or full down no in between.This still will not be LIVE power unless you also add the pump up at the gov. I think I saw a valve on ebay around $40.00 starting price. I'll go look and post back some item numbers so you can see a picture of what I'm telling you about.

# 7588248451 late style valve box from a power-trol. ad say ready to bolt on and go-- BEWARE it is missing the plugs in the back to block off the ports for rockshaft operation or even if it had them for cyl operation. The other one I found # 7586433294 was missing this stuff too.

Check out # 7584119291 I forgot about these they were made to fit JD's by Baker Valve co. I really have no experience with these and saw one once and only learned about them here at YT. One of these would maybe be the best set up. You hook it inbetween your existing set up and it will give you a place to hook up cyl. outlets. They go kinda high but are rare and I don't think you need anything else to operate. No special plugs like the JD units need and seem to be missing. These plugs will cost extra and you may end up with more in it than a Baker valve.

I'm going to have to stop by a friends house and see if he has any of this stuff laying around to sell. It would be a good idea to try the free classifieds here too.
