rebuilding a permco pump and need to make sure i got the right fasteners, is part number W1-65 the one that goes on the housing and end plates?

Question by: Bonnie R on Apr 10, 2025, 10:49 AM

W1-65 is the correct OEM cap screw for Permco gear pump and motor assemblies, specifically used to secure the housing components and end plates. Since it's a genuine Permco replacement part, it's built to the original assembly tolerances, so you won't have to worry about fit issues during the rebuild.

For Permco gear pump and motor assemblies, this OEM hex cap screw is used to secure housing components and end plates. It is meant as a direct Permco replacement part, so it matches the original assembly fit and tolerances for that job.
