Hi, working on Bobcat S220 , Water in chain case , All bearings bad. I have front bearings out. Have covers off. How can I turn axle to break rear spocket bolts loose? It's a single speed unit, but chains torque up against hyd motors and I can't turn axle enought to loosen the bolt. Am I going to have to hook up hoses and run motors to break bolts loose? Or will loosing Hyd lines allow the motors to turn. Thanks
