Part of working well is working well together. Using parts that compliment each other reduces road side service calls and removes unnecessary cost and frustration.
This post spotlights two parts we’ve previously covered, the Monster OAD™ Decoupler Pulley and the Almott 25AT Series Alternator, and focuses on how they work better together.
The Monster OAD™ Decoupler Pulley
The Litens OAD™ was designed specifically for buses and was given a vote of confidence by Cummins North America when they recommended it for all bus production as of November 2018.
The design reduces wear on the vehicle’s drive system. Not only does this reduce the likelihood of premature engine failure, it also helps with expensive maintenance costs.
This OAD (Overrunning Alternator Decoupler) works with your alternator by eliminating some of the effects of torsional vibration. Torsional vibration causes excess movement of the belt tensioner and this impacts the durability of all the components within the belt drive system, including your alternator.
The Litens OAD™ is unique because of a patented spring that absorbs torsional vibration. This spring allows the OAD to operate as a suspension system for your alternator, prolonging its life.
Another way the Litens OAD™ protects alternators is through its overrun function. This function brings the alternator to a slow, gentle stop when the engine shuts off, eliminating shutdown noises. It also works during transmission shifting when the alternator’s rotor spins faster as the engine decelerates.
Almott 25AT-Series Alternators
Any alternator creates ripple voltage as it switches from AC to DC current. However, reducing ripple voltage (and the associated noise) is critical for increased performance, particularly for vehicles featuring electronics and machinery that this noise interferes with.
Isolated Ground Terminal
Most alternators have a case ground that uses the mounting of the engine as the point where the alternator . Then the circuit completes as the current flows through the engine and the chassis and eventually the negative terminal of the battery.
Almott 25AT-Series alternators, on the other hand, connect directly to the negative terminal of the battery. The current is therefore routed away from the engine/chassis connection and stays clear of various vehicle components, computers, sensors, and modules.
Devices sensitive to fluctuations in their ground reference are at risk of malfunctioning. Almott’s alternator, with its direct connection, helps prevent these malfunctions.
How this Makes Your Vehicle Run Better
Both the Litens OAD™ and the Almott 25AT-Series alternator reduce the impact of forces created in the normal operation of your vehicle (torsional vibration and ripple voltage). With an OAD that protects your alternator and an alternator that protects sensitive components from malfunction, you are preparing your vehicle for far fewer roadside service stops.
