Loader GC2310 FEL very weak

ray66v · May 25, 2015

I replaced the generic fluid, in an older hydrostatic golf course mower I had with Permatran. It was running high temps on the gauge, and it ran noticeably cooler. It does make a difference sometimes.

Some GC owners have reported issues with generic fluid. And, a better additive package is what you are paying for.

The Kubota SUDT, or the Case HyTran, are also good substitutes.

If you want to completely rule out the fluid, I would only buy a premium product. A generic that says "premium" on the label, is still a crap shoot. You only need one 5 gallon pail, you are not going to save enough money to make it worth worrying about.

I don't think bubbles are unusual. But, I expect very small ones.

If the fluid is fresh it would be clear, Yours doesn't appear to be clear? Milkyness can mean there is moisture in it.

I would still make sure the filter is not a "this might work" unapproved generic substitute. No one wants to pay $40 for it. Especially, someone who is selling the tractor. Even if it is not the problem, it could be next time.

A Google search shows that a DK11 filter is a $5.42 Donaldson filter.

I see no application for this filter, to see if it is even a hydraulic filter. The price suggests it's just an oil filter.

Update: Among many others, its an oil filter for a model MF 35 tractor. :thumbdown:

I use Case HyTran, third change and so far so good. Moved alooooooot of dirt and snow with the FEL.

Sounds like 2 new agco filters are in order, first to filter out the guts of the last filter and second one to solve problem.

I've got an genuine agco suction screen and hydraulic filter on order from jacks. I'm getting new fluid also.

Shouldn't the old oil filter have filtered out particles and kept them from reaching the transmission innards?

What I would be worried about right now is, whether or not that solves your problem.

I hope it does, but your situation is unique. So, who knows.

You have to start somewhere. Sorry, you are the Ginnie pig.

I got the parts yesterday. New suction screen, hydraulic filter, and fluid.

As you suspected, it did not solve the problem.

I checked the lifting pressure on the loader-- maxes at 750psi. This doesn't lift much. I think it can generate a little more pressure when cold, but I haven't had the gauge on cold yet.

Air gets into the lines and creates flop in both the curl and lift. I can work out the air by moving each the full range, but the flop quickly comes back.

I finally got my grading done, but it was very, very frustrating.

Any ideas? Could this be the start of the spline issue? Take it to the dealer?
