Timing Belt:

Timing Belt Company were introduced to increase the efficiency of engines and reduce noise. It consists of steel wire-reinforced rubber that has cogs (semi-cylinder teeth) that fit in the corresponding grooves of the camshaft and timing pulleys. The rubber belts can naturally flex around the pulleys as it rotates and the rubber to metal contact requires no lubrication system. Torque is transferred through the cogs to eliminate slippage and minimize friction. Timing belts are also very efficient at power transmission - up to 98%. Their main downfall is longevity.

Timing Belt Advantages:

Quiet operation - no mechanical linkages that are constantly bending and no metal to metal contact

Lightweight - less inertial forces means more overall engine power and responsiveness

Lower timing belt replacement costs - valve cover removal is not necessary and the pulleys are easier to access

Timing Belt Disadvantages:

Longevity/Reliability - they only last up to 100,000 miles because rubber wears faster than steel. The belts are also more susceptible to breakage which may lead to extremely expensive engine repairs.

Durability - the rubber V Belt in the timing belts is more sensitive to weather conditions and will not last as long in extreme conditions.
