Newbie here. I have a bad hydraulic leak upon engaging the left-side track forward. I took plates off to get a look at the drive valve. From what I can see, which isn't a lot, the fluid forms drips on the bottom center of the valve body rather than on fittings. The drive valve is Bobcat's 6680245 Fluid reaches the ground near the left drive motor. Dunno if it traveling down tubing or (quite likely) if there is a second leak there. Can valves be reconditioned? Any thoughts on where to find one? Thanks.
