A new Eagle timing belt or Eagle timing chain most likely won't be the kind of part that you look forward to buying, but you probably won't have any choice. After all, the Eagle timing belt and Eagle timing chain are essential items for proper engine operation. By controlling the motion of the camshaft, the Eagle timing chain and Eagle timing belt essentially operate the valves on your motor, allowing fresh gas and air into the cylinders and allowing burned gasses to exit via the exhaust system. So what's the difference between an Eagle timing chain and an Eagle timing belt? Aside from the obvious-one is a chain and one is a belt-the Eagle timing chain and Eagle timing belt each have pros and cons that makes one more useful than the other in different engine designs. For example, overhead camshaft engines with a long run between the cam and the crank can benefit from an Eagle timing belt thanks to its quieter operation and lower lash. Older underhead cam engines, like those found on the original AMC Eagle, used an Eagle timing chain thanks to its durability, and because the shorter distance between crank and cam ensures that the Eagle timing chain won't make too much noise. The Eagle timing belt in your newer car most likely has a specified replacement interval-make sure you follow it closely or engine damage can result. If you've got an old Eagle with an Eagle timing chain, chances are your engine will need a full rebuild about the same time your Eagle timing chain needs replacement.
