Leakless Packing Nut (Chicago Rawhide Type)?
When I rebuilt my water pump I used a combination of the leakless bushing and packing nut (12570 & 12620 Bratton's Cat.). I have not had any leaks but I did find the nut had worked itself loose so my question is how tight should this nut be without having a negative impact on the seal and does the nut or the bushing require any special maintenance?
