![]() ![]() Regular oil changes prevent premature wear, stretching, and failure. Unless there’s a problem, distribution chains don’t have a replacement interval. Timing chains are heavier and more complex than timing belts, but they also last longer. Most automakers recommend replacing the timing belt every 60,000 to 105,000 miles. Oil and coolant leaks accelerate this deterioration. Timing straps are light and quiet, but they do not last long. So, Timing Belts, chains or Gears, what’s the Difference? This applies a mechanical force onto the driven shaft, transmitting mechanical power. The chain wrapped on the shaft’s sprocket rotates when the prime mover rotates. The holes in the chain links fit over the sprocket teeth. A conventional chain drive consists of two or more sprockets and the chain itself. Because the timing belt fails, the rest of the parts are not left behind.Ī chain drive is a mechanical power transmission system that uses chains to transfer power from one place to another. So, do all the work simultaneously, the timing belt, water pump, tensioner and crazy pulley. Tensioners, pulleys and water pumps will also wear out and need to be replaced. Most manufacturers recommend changing the timing belt between 60,000 and 100,000 miles.Īlmost all timing belts are fed through a series of pulleys and tensioners. The straps are flexible, and there is no metal-to-metal contact, which eliminates the need for lubrication. As a result, premature failures and damage to interference motors are prevented. The engine has recently returned to using more vital and durable timing chains.
