Abstract
Systems and methods described herein provide a belt drive with necessary power transfer for a vacuum priming system while enabling simplified belt replacement. In one implementation, an auxiliary drive system for driving a vacuum pump in a pump priming system is provided. The auxiliary drive system includes a drive sprocket attached to a drive shaft of a main pump, an auxiliary sprocket attached to a shaft of the vacuum pump, an idler pulley mounted to an engine bracket of the main pump, and an endless drive belt having an inner side and an outer side. The idler pulley causes the endless drive belt to engage the drive sprocket and rotate the auxiliary sprocket without the endless drive belt encircling the drive sprocket.
