What do you think - opinions concensus etc:
Does a discontinued obsolete NOS "New Old Stock" water pump have a "shelf life" ??
Was just doing some reading online on a few forums, a few Youtube videos and an article or two about the pros/cons of obsolete NOS New-Old-Stock parts. In this case in particular - water pumps.
Naturally this includes any older NOS "Reman" (factory remanuactured) & NORS "New Old Replacement Stock" (older "new" aftermarket replacement brands) water pumps too - all of which have been sitting on a shelf for years & years somewhere in storage.
As a general rule - at least a few articles and numerous pump rebuilders say in most instances generally stay away from any NOS water pump if it's 10-years old or more. Sure there could be a certain level of bias considerations (if they're in the rebuilding business) etc but here is what they say . . .
The main issue is the shaft seals either dry out or dry rot or shrink and there can also be some internal oxidation or even corrosion hidden on the shaft where it mates to the seal(s) - etc. As a result, the pump will either leak immediately or soon after installation or begin doing so prematurely and fail.
So if you're really wanting that original obsolete NOS pump - it's recommended to have it sent to a rebuilder or rebuild it yourself (if you have the skills & tools).
On a few discussion forums it seems it's debatable. Some say they've never had a problem and some have. Some just automatically send it out to have it resealed.
Do the restoration/rebuiler pro's have a good point? It seems logical. What do you think? What's been your experience?
Might be something to consider and think about anyway and I'm interested in what members might have to say about the subject
