Description:

Overrunning alternator pulleys are becoming increasingly popular on late model petrol and diesel engines, due to the
increasing drive belt speed and engine vibration fluctuations. An overrunning alternator pulley is used to smooth out
rotational irregularities on the alternator, which is caused from rapid acceleration, deceleration and even shut off.
During normal operating conditions these alternator pulleys can be rotating up to 18,000rpm and with major RPM
fluctuations unit failure can lead to belt noise, vehicle vibrations and also alternator or drive belt failure.
Nuline have developed a heavy duty replacement clutch pulley to disengage the alternator so it free spins during
rotational irregularities.

How does the Nuline overrunning alternator pulley work?
When the Nuline overrunning alternator pulley is rotated in the normal operating direction it connects to the alternator
working as a normal pulley. But during deceleration the pulley disconnects from the alternator shaft, allowing the
alternator to free spin. This is done by a special one way bearing that is mounted inside the Nuline overrunning
alternator pulley.
Advantages of using a Nuline overrunning alternator pulley
• Heavy duty designed for long service life
• Dampens drive belt vibration
• Reduced belt slippage during rapid acceleration or deceleration
• Reduced stress on drive belt and other accessory drives
• Increased alternator and drive belt life
• Reduction of drive belt noise
• Improvement in variation of drive belt tension

Signs of an overrunning alternator pulley failing
• Unusual drive belt noises
• Unusual vehicle vibrations
• Steering shudder
• Alternator not charging battery

Checking the overrunning alternator pulley
• Remove drive belt
• Check pulley for chips, dents or damage to belt grooves
• Check for excessive bearing movement
• Rotate Alternator pulley in normal operation direction, pulley should lock up and turn alternator shaft
• Rotate alternator pulley in opposite direction, it should spin freely without the alternator shaft moving
• Rotate the pulley in the free spin direction, it should feel smooth not rough

Kia takes aim at Lexus and Infiniti with the KH Concept Kia releases the first image of the Kia KH, a luxury RWD flagship saloon destined to be the Flagship for Kia and launching soon in Korea.
