Product Questions & Answers

Just want to make sure this is the right dowel for a Permco 3100 series housing. Is there anything else I should measure to be absolutely certain?

This dowel pin is designed specifically for Permco 3100 series housings. To confirm, you can check if your current dowel matches the 2-1/2 inch length mentioned in the product name.

Is this the dowel that keeps the housing halves lined up on a 3100 series Permco unit?

Question by: Peggy M on Aug 17, 2025, 7:18 PM

That's what it does. Proper alignment between housing components is what this part handles, keeping everything seated right so the assembly holds together the way it's supposed to. If your existing dowel is worn, missing, or damaged, the housing can shift and cause fitment problems throughout the pump or motor unit. Part number QZ-0577-17D is the correct Permco replacement for 2-1/2 3100 series applications.
