COMMERCIAL CARRIER JOURNAL | MARCH 2014 37 vehicle, as well as a variety of different clamping systems. For the cooling system, use a clamp that can provide uniform tension and sealing – especial- ly in low temperatures – considering the hose type, size and material. s Clamping systems: Some have specific torque ratings and require special tools for installation and removal. While screw-type clamps are simple to use and easy to find, more complex torque-specific clamps aren't as susceptible to overtightening and do a better job at providing constant equal pressure on the hose material. How to check belts Serpentine belts have replaced multiple belts on most of today's engine systems, so many trucks may have only one or two belts to inspect. Similar to hoses, a driver's hands are the best tools for making sure that engine belts are in good working condition. The primary inspection should focus on premature wear, which usually ap- pears on the belt's outer edges. Because of the high speeds of moving engine belts, the outer edges are sensitive to small misalignments in belt routing. Any lateral play introduced to a rotating belt quickly can lead to wear and eat into the belt's main body. Drivers should be alert for any signs of fraying on the outer edges; although the belt itself must be replaced, this type of wear probably also indicates a bigger problem that needs to be addressed. Older belts that have slipped through multiple PM inspections usu- ally show their age with cracks in the top, sides and bottom. Belts themselves should be supple and flex easily, so any brittle belt that cracks and resists flexing soon will fail and should be replaced immediately. Proper belt tension also is critical. On modern engines, spring-loaded belt tensioners automatically keep belts at the proper tension, and they also help eliminate overtightened belts that can place added strain on bearings, leading to eventual misalignment or failure. Check tension by pressing down on the belt to gauge its "give." While some play is normal, look for movement of about ¼-inch up or down; such excessive play is usually a sign that a belt tensioner is failing and needs to be replaced. The bottom line? Belt and hose inspection is vital to a truck's produc- tivity. The good news? Making sure that these components are in good working order is quick and easy.
