Moroso 97179 Vacuum Pump Update Kit for Old Style Pumps - 22641

The Moroso 97179 Vacuum Pump Update Kit is a complete rebuild and conversion kit designed for original design Moroso 22641 vacuum pumps. This comprehensive kit contains updated rotor and hardware to convert older original style pumps to the current design, and includes all internals: rotor, hardware, vanes, lip seal, shaft/hub assembly, thrust washers, and bearings.

Key Features:

• 4-vane configuration for Moroso No. 22641 pumps
• Complete internal components for full pump rebuild
• Can also be used to rebuild current-style No. 22641 pumps
• Converts older pumps from 10/32" set screws to dog-point set screw design with updated shaft and rotor
• Includes all necessary mating parts for complete conversion

Early production 22641 pumps utilized 10/32" set screws with a different shaft and rotor design. This was later revised to a dog-point set screw configuration, changing the rotor and shaft design. If you have an older original design pump and need to replace the shaft or rotor, all mating parts including dog point screws, shaft, and rotor are required. This kit provides everything needed for the conversion or rebuild in one complete package.
