Title: Spec'ing oil pumps?
Post by: bugnut68 on November 02, 2010, 18:24:38 pm
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.

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.

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.
