Air pump 911 SC
Posted: Tue Aug 23, 2011 12:54 pm
The air pump pulley (not the main fan belt, the little pump on the left side) flew off my 79 SC recently while driving. Makes a horrible noise flying around in the engine compartment, but no damage done. The nut from the shaft is nowhere to be found in engine compartment, so it probably fell out and got lost. Any harm in driving with the air pump temporarily disabled while I look for a new nut? I think I see a lot of cars where people take this off or remove the belt anyway, though I imagine a car wouldn't pass smog that way.
