A friend has a Bobcat CT235 tractor w/ FEL & he's got a hydraulic leak coming from a "bolt" under the right side floorboard. He said that it was misting out when he'd lift w/ the FEL but now it's spraying out pretty good. Is this common & does anyone know the P/N for the bolt that I can give him? Also, what kind/type of hydraulic fluid does the tractor take?
