Had a leak in curler cylinder of the loader. Had it repaired at a local hydraulic shop and had the control valve tuned up at the same time. Put new hydraulic fluid in. Everything seemed to work fine after reassembly but discovered some fluid leaking from the base of the PTO change lever. Never had a leak before. Any thoughts about what would cause that? In an attempt to see what was happening, removed the cir clip which allowed the spring and oil shield to slide up the lever, but can't figure out how to get the pin sets out. They will pop out a little with lever wiggling and a magnet to attract them, but can't get them all of the way out. Any suggestions?
