Hello. I acquired a speedaire m/n 2z157B and need to know what the oil capacity is? Can I still buy parts for this compressor. Is there a manual around that I could buy?
Also, on the pump case is a Model A-9 and under that is a 3 stamped on it, so asks John Paulsrud.
John was good enough to provide the following photos.

Not sure if this is anywhere near what you have, but may give a clue.
I found a few (one with many names? ) places that claimed the manual, but they may just be after a logon, so you’ll want to be careful.
As Doug writes, there are lots of places that say they have a manual but you are required to log in to get it, and they may only be after your email address. Another option is to contact Grainger directly, though their site doesn’t provide any information about the speedaire m/n 2z157B at all.
In terms of oil capacity, in the absence of a manual, get a quart of compressor lubricating oil (not automotive oil). Be prepared for an oil flow, and remove the two red plugs. Tilt the unit towards the plugs until all of the existing oil drains out.
Once you’ve cleaned up any mess (:-) then insert the bottom plug, and with fresh oil fill the sump until the oil level reaches the bottom of the threads on the top plug hole. That is the typical fill amount for oil.
Assuming that the fill is less than the quart (though it may take all of a quart so maybe have two?) by seeing what’s left in the new bottle of oil you can determine the fill capacity for that compressor pump.
Good luck, and please let us know how it turns out. Bill
