late 40,s H hydralics

We put a loader off of a super m on our H we know we don"t have live hydralics, there are two ports on the left side and one and the filler plug on the right could someone explain the proper hook up thank you Dave K
 
Okay....you know you don't have live hydraulics; I hope you're aware that you don't have double-acting hydraulics, either.
Plumb the two cylinders to the front port on the left and the one on the right. If your cylinders have line to each end of them, remove the line that retracts the cylinders and install a "breather plug" in those cylinder ports.
Oil under pressure will flow into the end of both cylinders when the hydraulic control rod is pulled all the way back. Releasing the rod to the little "step" on it will hold the loader in position. Pushing the lever all the way forward will release pressure on the cylinders. Gravity will lower the loader.
You didn't say....but this setup isn't going to work if you have a hydraulic cylinder on the loader bucket. If you have a "trip" loader, you'll be fine. If the bucket is hydraulically controlled, you're going to need considerable extra plumbing to provide two-way hydraulic power.
 
Hi Thanks for the advice. We have a M with live hydralics so are going to put the two way loader and bucket on it Dave K
 
Just wondering if you could plumb the return line into the the hydraulic fill pipe. Would it work that way? I have the same issue trying to run a transport disk with my MD, which has no live hydraulics.
 
You can do that, but why?

It won't give you "power down."

You would do that when you have large cylinders, like on a loader. The tops of the cylinders act as auxiliary reservoirs because the belly pump doesn't hold enough oil to raise a loader.

For a small cylinder on a disk there is no point.
