- New Holland WM25 with 200LC front end loader, filled R4 tires 43X16.00-20 and 25X8.50-14 (had a Kubota B6200D with dozer and R1 tires)
My FEL always seems loose and floppy, and if I move things around a lot with the tractor leaning forwards and also backwards, it all tightens up. But soon it's back the same way.
I'm wondering if the problem is that the bucket cylinders generally wind up loaded in compression when I park, because of how the bucket sits. If it's been parked a week or so, the bucket winds up curled, even though it was horizontal when I parked. I'm not sure what's happening to the hydraulic fluid on the closed end of the cylinder, but, could it be that on the rod end of the cylinder, air is coming in around the rod seal? That side of the cylinder is under some vacuum as the whole setup relaxes over time, and the rod seals obviously can seal against huge pressures when the fluid behind them is under pressure with the cylinder in tension. But if the cylinder's being compressed, isn't it easy for air to slowly seep through those seals?
I'm going to try some experiments, but I'm packing for a trip at the moment and so can't do anything with it for a few days. Wondered if anybody had any advice.
Thanks!
