I was given an old Cat fork lift with a redseal 4 cyl engine that had not run in ten years. Someone painted it and covered up the placards. Pretty sure it is a V40C. the forks would only go up about half way and the steering was wierd, acts like it was low on fluid. Then the tilt blew a line and drained a LOT of fluid. Now mast only goes up about 3". I checked the fluid tank under the floor board on the right side and it is full. Is there another hydraulic tank??? even before the leak when the mast was going up about 1/2 way the tank did not seem to go down any and after the leak the tank level did not go down???
