All Internals, 3 Vane Update Kit for Moroso No.

22640.

Early production Nos.

22640 and 22641 pumps utilized 10/32” set screws and a different rotor and shaft; this was revised to a dog-point set screw, changing the design of the rotor and shaft as well.

If you have an older “original design” pump and need to replace the rotor and/or shaft, the current style can be used; however, all mating parts (dog point screws/shaft/rotor) will be required.

These are available in kit form; No.

97178 (3 vane for No.

22640) and No.

97179 (4 vane for No.

22641).

Inspecting your pump prior to ordering is recommended to ensure the correct parts.
