Oil Pump Rebuild Question

[Ziggster]

I want to tear down my C59A pump and possibly “rebuild” if necessary, but I’ve searched here and in the imterweeb, and really couldn’t find much info. I seem to recall based on past searches last year, the consensus seemed to be to keep the OEM vs buying newer “Chinese” manufactured pumps due to failures. I have two pumps. The “original” (stamped/cast with 8BA6604B) from the motor I purchased and one I picked up along the way somewhere (just stamped/cast with USA and H2). I don’t feel any end play in the “original” whereas I feel a bit in the other one and it makes a metallic clicking noise when I pull on the gear end of the shaft. The other pump also has some kind of splash shield, and I was wondering if this would be beneficial if I switched it to the “original” pump. Is there some info on the specs I could use to make sure my pump is good to go?

The “original” pump.
