Using Powr-trol side ports on John Deere B

pmarkel · Jul 29, 2015

I have a 1948 John Deere B to which I am going to attach a 45 series 1 loader using the side ports of the tractor's powr-trol. Besides using dummy plugs in the rear of the tractor's powr-trol, is there anything else I need to alter in order to simply run 90 degree adapters out of the side of the powr-trol in place of the current 3/4'' pipe plugs? Thank you for your time.

Sincerely,

Peter Markel

Might be a good idea to add quick couplers in there too ?

Agree with [b:654c4848f0]Mike M[/b:654c4848f0] on adding quick couplers.

Take a look at the photo below of "Big John" our 55 Model 70 diesel.

Hope this helps.

Yes that helps, that's exactly what I'm aiming to reconstruct. But you didn't have to alter anything [b:dd751d737b]inside[/b:dd751d737b] the powr-trol in order to use those ports?

No alteration needed. Just remove the pipe plugs and install the fittings and couplers. I can't remember which hose goes where though ? IIRC ? You will only have pressure on one side as you push the lever forward to lift the loader. Back is down and just goes to return.

Agree with [b:654c4848f0]Mike M[/b:654c4848f0] again.

You are correct, nothing was changed inside the Powr-Trol to use the ports.

Take a look at the photo below of the hydraulic hose from the baler to the lower, bottom port.

The one hydraulic hose serves as both supply and return.

When the Powr-Trol lever arm is moved forward, the rockshaft raises.

Then the hydraulic hose "supplies" oil to the cylinders.

When the Powr-Trol lever arm is moved backward, the hydraulic hose "returns" oil to the reservoir.

Then the rockshaft lowers.

The <a href="http://www.external_link.com/p-125-deere-hydraulic-service-manual-sm2011.aspx">Hydraulic Equipment SERVICE MANUAL SM-2011 (Dec-52)</a> is an excellent reference.

Hope this helps.

If you want a little more oil capacity in the reservoir you can clamp a strap or angle iron to the rockshaft with the rockshaft raised and fasten that strap to something to keep the rockshaft from going down every time you lower the loader to the bottom. Then you can top off the reservoir to replace the oil it took to raise the rockshaft. One caution is if you ever allow the rockshaft to go back down oil will be coming out around the rockshaft from an over full reservoir. It doesn't hurt anything but it makes a mess. We had a Caswell loader on a 51 A and after years of waiting for the rockshaft to hit the top before the loader started to raise if I forgot and left the hyd lever back I chained it up with something, I forget what it was I used. It's been 44 years ago when we took the loader off that tractor.

Thank you, that does help. I have also heard it suggested to use one hose for pressure and one for return (both tee'd off to the respective valves on the loader cylinders). To your knowledge is there any difference in performance between the two setups?

Used one of our Model 70 gas tractors to power a log splitter.

Same setup as on the Model 70 diesel, but with two hydraulic hoses to the log splitter.

No noticeable difference in performance between one hose or two hoses.

Hope this helps.

We plump [these pic] ball valve shutoffs [either elbow or strait] in side ports , to shutoff oil flow to loader [leaving hoses connected no oil loss or mess] rockshaft [3pt.] can then be used normally.. Rockshaft must be locked or tied in up position for either hyd. side or ports to work.. Powr-trol is single lever system ; only one function of the 4 types can be used at a time....
