I am restoring an ac WD. Changed all fluids and the when I raise the 3pt it seems slow and labored. Also has an unsettling noise involved....I used 5w 20 oil in the hydraulics...any ideas?

Hydraulics are initially slow in cold weather. Could that be the cause?

They run pretty slow when cold. Did the noise sound like a chattering sort of noise? Pretty normal too. When the cylinder rods hit max stroke, the pump will chatter at ma pressure then unload and chatter some more.

I've never had any trouble using 10-30 or 10-40 Engine (Detergent) oil in my Hydraulic system..
Are you familiar with the WD and the normal sounds associated..??
Maybe you had a little air in the system..??

It does sound like a chatter....just sounds a little rough is the cause for concern. I'm not really familiar with the tractor but it was slightly alarming because I don't recall the noise before I changed the fluid but I didn't play with it too much or have a load on it then either. And yes its been cold here
Detergent oil DOESN'T foam..Thats an "old wives
tale", in fact detergent oil has LOTS of Anti-
foam inhibitors. The "TERM" "DETERGENT" in lube
oil means that it "holds dirt in suspension"
until it reach's the filter, where the dirt is
filtered out, thus giving a cleaner oil!

So are we saying that its probably normal and I shouldn't worry about it?
Was it slow and labored before you changed the fluids?
As far as being normal a lot of these old tractors do that. It doesn't mean it is right.
As for worrying about it I doubt the tractor will dissolve.
Allis Chalmers, Stated in the manual the oil used must not foam. The local dealer said do not use detergent oil. I understand detergent oil holds the dirt particles in suspension. The hydraulic system on a WD does not have a filter, that is why I do not use detergent oil in my WD's hydraulics plus the fact I wonder what it does to the seals.
I agree modern day hydraulic oil is better than what they had back in the day but I still use a straight weight non detergent oil for the hydraulic on my WD.
In my opinion the fact that over the years a lot of farmerts did or did not do what the manufacture recomended speasks well these old tractors.

The pump is a piston pump running on a cam shaft.
you will feel a slight vibration as it lifts. If it studders badly you may have a broken spring or two that hold the pistons against the cams. Ive not had that happen too often but have found it to cause a slow gerky lift.
