 Topic: Du-al loader uneven lift
Posted: 23 May 2018 at 1:05pm |
|
I have an old dual loader on a D15. I was liftig out some stumps and it started lagging on the left side when lifting. I took the left lift cylinder off and repacked it with new seals. I've replaced the hoses to that cylinder as well. It's not leaking but still sags/lags on that side. The right lift cylinder seems to be doing the lion's share of the work.
Any suggestions? What should I try next?

Are they one-way cylinders?? with only one hose to each cylinder??? Loader cylinders are plumbed together and provided they are the same diameter and design of cylinder, they will lift the same weight. The only thing that keeps them going up equally is the loader boom itself. If it is twisted,cracked or broken, that could be the problem. For what you are doing, the chain should be in the center, not off to one side or the other. If you have 2-way cylinders, you could have blown packing in one, but you'd have a settling problem then too, which you didn't mention.

If there are any hydraulic couplers between the cylinders, get rid of the coupler and make a direct connection with hose.

OK.... you could swap cylinders left to right.... IF the sagging is now on the right side, cylinder is 'funny' ( maybe not packed properly), If left side sagging, I suspect hoses or fittings, on left side.
? Does it lift evenly without a load ?

Some of the old loaders have different hole connections for the cylinders for varying the lift height/ lift strength. If your has this, are they connected to the same hole on each side?

Both hoses need to be plumbed to the same port. One of the ports has a delayed lift for the rear cultivator "scratchers".

I agree with Steve. I bet you sprung the metal in that old loader. Next time you pull stumps, put the chain on the high side.

Thanks for the info. I'm leaning toward the idea that I sprung the loader frame. I may swap the cylinders to check. I'll update this after I try that.

It seems sprung. I swapped the lift cylinders yesterday and it still sags to one side. It still lifts fine, so I'll probably leave it alone. I'm cleaning it up to sell anyway.

The W9 loader I have on he 45 was seriously abused when I got the tractor. I proceeded to abuse it more trying to doze out some footings in the old barn after tearing it down.
I twisted the frame about 6 inches down on one side, so I anchored the high side to an unmovable object and proceeded to twist it back. It did help considerably with the blade being level when I use it for pushing snow.

I twisted the loader frame on my loader on my WD some years ago and did the same as Charlie. Chained the high side to an old Twin City tractor and give 'er a good lift a few times until the frame pulled back straight. Been fine ever since.
