Corvette C3 Smog Pump & Parts
 

Believe this is from a late 1972 model year C3 vette, please correct me if you can ID it and that's incorrect.
7801149 smog pump, spins freely. Has black plastic fan.
Pump body cast end cover is dated '76' for 76th day.
Machined area on pump side has assembly date code of 16721S which decodes to 167th day of 1972, 1st shift, S is the pump configuration (no pressure relief valve).
Included is everything attached to the pump in the pictures:
black fan, pulley which is stamped 3917234AL, diverter stem and plastic valve, and mounting bracket. The long bolt on the mounting bracket is missing the nut.
Please also note the pulley has some minor damage as shown - the outer lip has a bend, am sure it could be straightened okay but disclosing that issue up front.
Asking US$160.00 shipped, via PayPal F&F please. It's quite heavy, so if you just wanted the pump and not all the other parts, that should bring the total down a little.

10721S

I can't make out the first 3 but the forth digit is a 2 which is 1972 then 1st shift saginaw
With the squared black fan - it fits as a 1972 pump perfectly. (72 is the only year with squared edge black fan.)

Thanks James. It isn't the best photo of the assembly code, but it is 16721S. I checked because it seemed a bit of a gap from the end cover cast date (76th day).


Open to any offers, if I'm way off on the price. Just hoping someone here could use it.
