Belts function at multifarious levels to perform various roles in a Mercedes Benz. One is to ensure safety among its passenger while the other, to grip important engine components together.
Of the Volvo Belts installed into the vehicle, the safety belt is a chief failsafe in minimizing the severity of injury in times of collisions or other forms of accidents. With its virtually "life-saving" function, it dramatically decreases mortality rate in vehicular accidents. With its usage, passive restraint came into an advent to further promote passenger safety. Initial batches of these passive restraints were modifications of seat belts themselves. The belts were coordinated with operations of opening the car doors and starting the automobile, which caused belts built into tracks in the doors to wrap around the driver or passenger when the seat was occupied. Eventually, a second passive restraint during impact was devised in the form of an airbag.
On the other hand, another Volvo Belt can be found along the premises of the engine compartment. Made of high-tensile strength and synthetic rubber, the drive belt serves as the bridge to the engine while providing power to front-mounted sub-parts like alternator, air condition compressor, power-steering pump and injection pump. The V-belt is another kind of drive belt with its "V"-shaped cross-section. Such is creating a gripping effect on the pulleys of the component. For more responsive contact with the pulleys, a serpentine belt is preferred.
The Volvo Belt that coordinates the turnings of the crankshaft and camshaft. It is a reinforced band of rubber to ensure that the valves and pistons are in exact order. A valve-piston combination must push down the individual cams on the camshaft at just the right moment. This is compared to pedaling a bicycle and waiting until one pedal has reached the top before the rider can bear down on it again. If the rider tries to push down on the other pedal too soon, the foot might fall through or the pedal could break off. Timing belts work to prevent the pistons and valves from pushing on the camshaft before it has reached a full cycle.
Volvo Belts are tough-built and last a long time. But there will definitely come a time when it reaches its vulnerability stage. A damaged Volvo Belt could snap instantly, while the engine would grind to halt or become inoperable. Worst, valves and pistons may drive themselves into the camshaft and become damaged. In replacing a , professional help should be sought. Peripheral parts like the water pump should be removed, first. The mechanic should also synchronize the camshaft and the crankshaft with a timing light, or a special strobe light.
