Product Description

Engine PARTS 

Types

Gear   or   chain   systems are also used to connect the   crankshaft   to the   camshaft at the correct timing. However, gears and shafts constrain the relative location of the crankshaft and camshafts. Even where the crankshaft and camshaft (s) are very close together, as in pushrod engines, most engine designers use a short chain drive rather than a direct gear drive. This is because gear drives suffer from frequent torque reversal as the cam profiles "kick back" against the drive from the crank, leading to excessive noise and wear. Fiber or nylon covered gears, with more resilience, are often used instead of steel gears where direct drive is used. Commercial engines and aircraft engines use steel gears only, as a fiber or nylon coated gear can fail suddenly and without warning. 

A belt or chain allows much more flexibility in the relative locations of the crankshaft and camshafts.
