Take a look at that replacement alternator ? Could it ruin your customer relationship?
Millions of vehicles are now factory-equipped with an Overrunning Alternator Decoupler (OAD) rather than a conventional solid pulley or one-way clutch pulley. A failure to install the correct replacement design could cause severe damage to a vehicle's belt drive system.
An OAD Decoupler is similar in appearance to other pulley designs but plays a vital role in synchronizing the belt drive system. When replacing an OAD-equipped alternator, the only acceptable choice is another OAD unit.
When working with any pulley or belt tensioner for a late-model vehicle, always replace Original Equipment (OE) design with OE design. After all, your reputation is at stake.
Many new vehicle accessory drives are realizing a 1.5% to 2% fuel economy improvement with a Litens OAD. These improvements are possible by utilizing Litens' Lean System design philosophy. Lean systems, with only Litens' OAD, can significantly reduce the common parisitic losses found in accessory drives, due to the belt bending that occurs during operation. The parisitic loss reduction is a result of a holistic approach to accessory drive - drive layout, OAD, and tensioner design/matching.
