What other manufacturers (other than Litens) produce OAD decouplers?
No other manufacturers, in North America or around the world, produce OAD decouplers. This technology is fully protected by patents and intellectual property laws. Some other manufacturers attempt to market their “Overrunning Alternator Pulleys” (OAP) as an alternative to OAD technology, but the performance is not comparable in any way. These one-way pulleys do not adequately absorb drive belt system vibration. ( Back to Top ) What type of testing/specifications are required by vehicle and engine manufacturers using OAD decouplers? OAD decouplers pass a rigorous series of tests to ensure exceptional performance and durability. These tests include: lug test, start-stop, wide-open throttle shift simulation, and 3,000-hour D4 speed change test. Others include brutal salt spray and mud resistance evaluations. ( Back to Top ) What is the expected service life of an OAD decoupler? Early design versions have provided service life of 40,000 to 60,000 miles. More recent versions often last more
