Abstract
An air-cooled heat exchanger has a frame assembly, a plenum supported by the frame assembly, an engine and a fan assembly. The engine includes a drive shaft and the fan assembly includes a fan connected to a fan shaft. The fan assembly is configured to move air through the plenum. The air-cooled heat exchanger also includes a drive assembly connected between the engine and the fan assembly. The drive assembly has a fan shaft sheave connected to the fan shaft, a driver sheave connected to the drive shaft, an idler pulley, and a drive belt in contact with the fan shaft sheave, driver sheave and idler pulley. The air-cooled heat exchanger has an idler bearing adjustment mechanism that is configured to adjust tension on the drive belt by adjusting the position of the idler pulley relative to the drive belt.
