Hydraulics Mystery:loader:Can you solve?

[Rocwin]

I just wanted to comment on using WD40 instead of grease, because it kinda bugs me. WD40 is one of the worst lubricants I've seen, it is little more than a aersol penetrating oil, and, in my opinion, does more harm than good. You should look into using a good lubricant with a solvent carrier to seep into pins and bushings, we use a product called HHS2000 by Wurth.
I realize there is not much out there as cheap as WD40, but there is a reason why it is so ridiculously cheap.

My tractor was doing the same thing.

Turned out, it was an internal issue with one of the cylinders. The nut had backed off completely from the cylinder rod with the piston 'floating' inside and would let all of the hydraulic fluid bypass on that side.

Hope it's something simpler for you.

Though it really wasn't to bad to fix.

Well did you fix it?

That's a smileyface looking at his watch and waiting. Didn't work well. I brought it in from elsewhere. Sorry.

We have a winner! I would bet the mortgage this is the problem. Seen it a thousand times.

Earlier this winter, I had a similar problem.

My troubles were an o-ring in the relief valve between valve blocks (not sure of teminology) had torn sending fragments into the system; worst off was the relief valve itself although the contamination was observable by the color of the hyrdo oil.

I changed the filters. A mechanic changed the o-ring and dislodged a piece of rubber from the relief valve. Pressure THROUGHOUT the system was restored whereit had been impaired in most but not all parts of thr system. The dealership charged $265 excluding the cost of the filters that I had changed before taking the tractor to the local Kubota dealer.

Interesting...
I need to look for a manual for the loader... This sounds easy enough for me to do that o-ring replacement.
