My new L245DT has a leaky cylinder on the L1200 FEL. I have a FEL manual that shows exploded views of the cylinders and replacement parts. It's the type of cylinder where the cylinder itself has a slot that a retaining wire ring goes through when you rotate the cylinder head/cap. No luck finding replacment seal parts online yet. Anyone done this job? Are parts available through Kubota, or do I need to get it to a hydraulic shop?
