Timing belts are positive transfer belts,and have the ability to track relative movement. This belt is part of the internal combustion engine and controls the timing of the engines valves. Timing belts replaced the timing chains that were popular until the early 1970’s. This belt has teeth that fit into a matching toothed pulley. When this belt is correctly tightened, they run at a constant speed, have no slippage, and will transfer direct motion for indexing or timing purposes. Timing belts have started replacing chains or gears. Advantages of a belt over chains or gears include not having to lubricate it, and less noise being created. Timing belts need the least tension out of all the belts and are among the most efficient. These belts can handle up to 200 hp at speeds of 16,000 ft/min.
Timing belts can also come with a helical offset tooth design. The helical offset tooth design creates a chevron pattern which allows teeth to engage progressively. This pattern is self aligning and is more efficient at transferring power. Newer timing belts also incorporate curved teeth instead of the old trapezoid shaped teeth which helps them last longer, and is quitter. When replacing a timing belt, care must be taken to ensure that the valve and piston movements are correctly synchronized. If not synchronized properly when replacing the timing belt, you can experience problems with valve timing, which can cause collision between valves and pistons. To help protect against this, timing belts have painted marks on them to help ensure that you align them properly on the camshaft gears and crankshaft gear. Timing belts are usually covered by metal or polymer timing belt covers which help keep them from being exposed to the elements. Timing belts are typically replaced every 60,000 to 90,000 miles to avoid a breakdown if the belt breaks.
