What does ADG mean in UNCLASSIFIED

Accessory Drive Gearbox (ADG) is a component used in internal combustion engines that helps transfer power from the engine to its accessories. It works in conjunction with a crankshaft and other rotating parts of the engine to regulate speed and provide a smooth mechanical connection between various components of the vehicle.

The common functions of ADG include transferring power from the engine to its accessories, regulating accessory rotation speeds, providing mechanical connections between different components, smoothing out torque fluctuations, controlling accessory driveshaft rpm, boosting acceleration, producing higher torque outputs at slower rotational speeds, reducing noise levels during operation and ensuring quieter operation overall.

Most accessory drive gearboxes are made from high strength steel or aluminum alloys which can withstand greater loads than regular steel or cast iron. Steel alloys are typically used for applications that require higher toughness while aluminum alloys are best suited for applications where weight savings are desired.

Installing an ADG usually requires removal of existing components such as flywheels or crankshafts in order to access mounting areas for proper installation. Afterward, any necessary gaskets should be installed before placing the new gearbox on top of them. Finally, bolts should be tightened according to manufacturer specs and checked periodically for proper tensioning afterwards.

The maintenance frequency of an ADG varies depending on factors such as usage patterns and environment conditions but generally it should be looked at every 10k-15k miles or once per year whichever comes first. This includes visually inspecting hoses and lines connecting components as well as examining oil levels or checking pulleys for wear or damage signs among other things.
