INA Overrunning Alternator Pulley

Service Info

INA Overrunning Alternator Pulley

Dampens the belt drive and protects the components

Product description:

The rotational movement of the crankshaft in the internal combustion engine is not uniform. The reason: The four-stroke principle brakes the crankshaft and accelerates it again, causing vibrations. These rotational irregularities are also transferred to the front end auxiliary drive and cause an increased load on all components there. To decouple the generator of these rotational irregularities, an overrunning alternator pulley is fitted. This transmits the power of the crankshaft in just one direction and calms the belt drive as a result.

If the overrunning alternator pulley is defective, the drive belt starts to wobble, extreme noises occur and all components are affected. The INA overrunning alternator pulley is the perfect replacement in this case. It ensures durability and maximum precision for the established overrunning alternator pulley technologies OAP (overrunning alternator pulley) and OAD (overrunning alternator decoupler).

Our tip: If you change the one-way clutch, you should also replace the belt tensioner, tensioner pulleys and the Ribbed V-belt so that everything works perfectly together again.

Benefits:

  • Reduction in belt vibration
  • Improved noise behaviour
  • Reduced tension forces and paths
  • Increased service life of the tensioner and belt
  • The undisputed market leader with more than 250 million OAPs produced since market launch
