Yellow Jacket 93047 Replacement Drive Coupling with Coupling Spider for Bullet X 3 5 7 Cfm and Superevac 4 6 8 11 Cfm Vacuum Pumps

Product Description

The Yellow Jacket 93047 is a replacement drive coupling with coupling spider designed for use with Yellow Jacket BULLET X and SuperEvac vacuum pumps. HVAC technicians and refrigeration service professionals rely on this part to restore full pump function when the original coupling wears out or fails. The drive coupling connects the motor shaft to the pump mechanism, transferring rotational force so the pump can pull a deep vacuum on refrigeration and air conditioning systems. The coupling spider is the flexible insert that sits between the two coupling halves. It absorbs vibration and shock loads during operation, protecting both the motor and the pump internals from stress. Over time, the coupling spider can crack, harden, or degrade, leading to slipping, noise, or complete loss of pump drive. Replacing the drive coupling and spider restores reliable torque transfer and smooth operation. This part is compatible with Yellow Jacket BULLET X vacuum pumps rated at 3, 5, and 7 CFM, as well as SuperEvac vacuum pumps rated at 4, 6, 8, and 11 CFM. These are among the most widely used vacuum pumps in the HVAC trade, making this a common service part for shop inventory. The 93047 measures 3 inches in length, 3 inches in width, and 1.5 inches in height, making it a compact component that fits within the pump housing without modification. HVAC technicians should inspect the drive coupling and spider whenever a pump shows signs of reduced vacuum performance, unusual noise, or vibration during operation. Keeping this replacement part on hand minimizes downtime during service calls and equipment maintenance.
