My Bobcat 533 has a couple leaks. The hydraulic tank leaks down over time. Holds like 3 gallon of motor oil and is not a pressure leak but if I let it set for 3 or 4 weeks it leaks out. Wet on the ground under it but I cant find the leak anyplace. Hard to see down in there though but just cant find it. Now I have sprung a leak on the rear axle. I havnt used it in a couple months and was looking at it last weekend and seen oil had run down the tire and pretty wet on the ground. Anyone here ever changed a axle seal on one of these older small skidsteers? What am I getting into? Cant find anything on google for my model 533.
