Spec'ing oil pumps?

[bugnut68]

I've got a couple oil pumps (Schadeck) that came with a lot of parts I recently bought.  Both are plugged for full flow, and I would like to know how to spec them to see if they're still any good/

I guess my other question is are used oil pumps considered expendable/disposable?  Just wondering if they're worth reusing and how to check to see if they are.

Oil pumps are cheep, just replace it if its not new.

I only ask because I hate throwing away stuff in the event it may be useable for, say a STF motor.  I guess I can keep that purpose in mind...lol.  oil pumps aren't hard to swap out, even with an assembled engine, in my experience.

use the Bill Fisher book.

use the Bill Fisher book.

Just so happens I have two copies... an original and a reprint.

as cheap as they may be, it would be a waste to trow a good part away... so try to measure it like in the Bill Fisher book.

but here is another question. can the gears be smoothed out agian? just rub it on a perfectly flat sandingpaper so the gears and housing are flat again? or is the slack on the drivegear and maybe the space between the gear and housing a bigger issue?

I will take a look again as my only examination has been cursory at best, so far.  For me, I'm not a cheapskate by any means, even though for me 40 or 50 bucks isn't money I've got growing on trees... it's just purely a matter of not wanting to dispose parts that may be still solid enough for such a project as a STF type of engine.
