Timing Chains and Gears from Sears Extend your Vehicle's Life

A timing system will either use a timing chain or a timing belt to connect the crankshaft to the camshaft, and it provides the timing for the correct valve opening and closing. Both of these parts have long service lives and precise timing. A timing belt or chain will often last 100,000 miles or more before showing wear. With use, however, a vehicle's timing system will need to be replaced.

There are some symptoms of a failing timing system that will alert you to replace these parts. Noise from inside the timing chain cover may indicate the timing chain has stretched. As the timing chain stretches, the ignition timing will be affected. Because of this, retarded ignition timing is another sign the timing chain may be failing.

Once you've diagnosed a stretched or broken timing chain, you can select a replacement. Always follow manufacturer's recommendations when replacing parts of a timing system. A timing belt should not be removed and reinstalled unless there is very little mileage on it. When a timing belt has been in use, it will stretch and should not be reused. When installing a timing belt in a car's timing system, the belt needs to be snaked around the various pulleys. Orientation of the belt surrounding key parts of the engine is vital to its use. Tension of the belt is another key to installing a timing belt. Too much tension can cause excessive wear on various parts of your timing system. Too little tension will poorly affect an engine's timing.

Users should be aware of some key factors when installing parts of a timing system. Engine belts should never be stretched. This can damage both the belt and parts of the belt and pulley system. Belt covers should also be included, where appropriate. These protect your belts.

A number of problems can occur with timing chain installation. Misalignment can be a problem with installation. Installing the cam sprocket backwards or using the wrong washer can cause it. Additionally, if the cam sprocket and crank sprocket are not aligned, the timing system will wear quickly. This is why it's crucial you select the appropriate part for your vehicle model.

When replacing a timing belt or chain, consider replacing the entire timing system at the same time. There are a number of components involved in a timing system. When replacing a timing chain or belt, also consider replacing or buying new timing covers, crankshaft keys, block protectors, timing pointers, timing chains, replacement bolts, camshaft buttons, dampers, tensioners, pulleys and more. Sears carries the best auto part brands. Shop Goodyear, Gates, Rock, Dorman, Powerbuilt, Cloyes, Craftsman, Mr. Gasket, JEGS and more.
