kristopherdb Posted September 5, 2017 Share Posted September 5, 2017 It seems my air pump is frozen solid from being disconnected for 20 years. I need it to pass emissions of course. I saw a turning one on a F250 but wasn't sure if they are cross compatible or not? I would assume as its mechanical air is air and as long as its close it will work? I was going to pick up a refurb one off amazon but of course the one I have if i have to replace identical is twice the cost. Just trying to see if the hive has any ideas? As far as I can tell I currently have a 32-290 Smog pump Link to comment Share on other sites More sharing options...
Gary Lewis Posted September 5, 2017 Share Posted September 5, 2017 The only way to determine your pump's part # is to get the calibration code for your engine, which was originally on a sticker on the valve cover. It looks like 9-76C-R12, although that's for a 1989. With that I can look up what pump you should have. And, there was something like 35 different pumps, as shown below, although none of them are a "32-290". (Where did you get that number?) But, I'm going to guess that a pump from another truck of this era would work. That's purely a guess, but it might be worth a try. Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted September 5, 2017 Share Posted September 5, 2017 I've 'adapted' A.I.R. pumps before, for the same reason you mentioned. Brackets, pulley flanges, shaft offset (stickout) and outlet elbows differ. WAY easier to just get the right one. Thankfully I don't have to go through that any more Link to comment Share on other sites More sharing options...

And, by the way, I discovered today that there was a 460 with only one "smoke grinder", as Bill likes to say. I thought they all had two, but apparently not.

I thought they all had two, but apparently not. I think up through 84 or maybe mid 84 when the exhaust changed they had one, so 1983-84 would have one, 1985-87 got the booby prize, dual smoke grinders, 1988-97 they went back to one, but 1988-92 it only fed the catalytic converter and since Darth never had one (sticker reads NON-CATALYST) I don't need one.

O'Riellys replacement the 290 is the only one that looks like mine Link to comment Share on other sites More sharing options...

kristopherdb Posted September 7, 2017 Author Share Posted September 7, 2017 Are you going to buy one? I bit the bullet and bought a new one, this project is a money pit!! Mufflers and exhaust tomorrow and then back to emissions for testing again. Link to comment Share on other sites More sharing options...
