Look for any loose or damaged bolts. Replace damaged bolts or missing bolts with original equipment parts only. Retighten bolts to a torque of 475 75 N m (350 55 lb ft).Replace ROPS mounting pads, if the ROPS rattles or makes a noise when the machine is operated on a rough surface.Do not straighten or repair by welding reinforcement plates to the ROPS.Contact your Caterpillar dealer for repair of cracks in welds, castings or any metal section on the ROPS.Winch Oil System
