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™) pulley 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™ pulley. 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.
