Ford 550 backhoe help

I was wondering if someone could give me some ideas here. I just bought a 1976 Ford 550 backhoe, and have discovered that when I actuate the lever for moving the hoe boom sideways that it only moves at one speed, which is "fast", with no slow movements. If I try to use it on a job, I'm going to wreck something. It is either "all" or nothing. You start to move the lever (it does this either direction) and the boom just suddenly swings with a huge jerk, with no in between. I am an absolute beginner at hydraulic things...is this a problem anyone has encountered before, and if so, what can be done about it?

Thanks, Alex

i wouldn't get into flow restriction etc....That sounds like it would just be masking a problem. And with flow "restriction" you get heat ....Like one of the other guys stated...check a parts book well and see if they show orifices or special fittings in the swing circuit lines..check on either end.

Your dealer might be the resource you need at this time. As he might be familiar with the issue at hand, and know off hand what's required to make it right.

I might thing someone got into the valve bank and messed with one of the spools or something causing the maladay you describe.

Welcome to the world of tractor backhoes. Thats why when you see someone running one they're always bouncing around and all you hear is slam bang clatter clatter. Some machines are a bit less savage than others, but all are pretty rough to operate.

I bumped into a former prairie farmer/rancher here on our little island the other day, and he mentioned that there is often a means of adjusting flow-rate on most hydraulic systems. Does this ring a bell with anyone? Now the challenge is to actually get at either the cylinder itself or the valve that controls it. It is all very hidden away. If anyone knows the secret of adjusting flow rate, do tell!

I have also discovered that by lowering the revs I get some control over it, but then there is less power for breaking out earth. That'll help for light work, in any case.

I should have bought the 1992 JCB 217s I had considered!

There are adjustable flow control valves you can buy and install in the line between valve and cylinder to slow the function down. Check out Bailey.net for just such items.

I have a Trojan backhoe that I fitted to my TD340. I was lucky to get a good parts manual that showed a couple of flow restrictors installed in the valve unit for just certain components of the hydraulic system. If these are left out when rebuilding, then you can get too rapid movement. You might try to look at the documentation for your backhoe unit; which can probably be tracked down.

Incidentally, my rotation is accomplished by a hydraulic rotating actuator, a flat cylindrical unit, which I don't think is very common. But I don't think that's the circuit that had the flow restrictor.

I definitely think I'll take it to a dealer for all of this. There is a big sticker from Coast Tractor on one of the loader arms with their number, and I was told that they were the ones who replumbed most of the machine, so I'll bet (I hope) they have all the answers. Perhaps I am expecting too much fine adjustment out of an older machine, but I think these things were pretty well engineered back in '76.

This machine is going to be a great education for me for an introduction to backhoes. Luckily a lot of the hard work has already been done on it, and it actually a nice machine to use (except for the overly quick boom swing prob) -- I'm getting to like the concept of being a backhoe operator for a living. A few more holes for practice in my back yard and I'll put out my flyer and see if anyone on the island calls me up.

Now, if you don't mind, please have a look at my posting on Backhoe safety. I want to know everything beyond the obvious, because it isn't all obvious.

Thanks,

Alex
