Hi Paul~

The PMA 1000 will have the same oil holes as your fan motor did...That & keeping it rust free, are about the only things you can do as far as maintenance...

That pump is one of the most reliable pumps out there...After the initial sale, and providing it is not run without water...I can never make any money on those things...They can be a ball of rust with the capacitor hanging off the side & still run...

Hi Steve:  I'm continuing to work my way around my a/c system starting at each of the self-contained units and then their Supply & Discharge hoses...and thanks for your help so far.  Now I'm back to the pump.  It is a Marine Air PMA1000C, which I understand is also known as a March AC-5C-MD.

Is there anything on this pump that should be serviced/checked/cleaned/oiled.... and if so, how is this done?


thanks again
