Smog pump

[paul robb]

Need some information on a 1966 smog pump (A.I.R. PUMP )The pump on my vette sounds like a bearing is starting to go out. I can't find much information or pictures in any of my books. Does anyone out there have a diagram or know anything about replacing the bearing or bearings, or if this is a difficult repair can someone recommend a shop that they have used before. Any information would be greatly appreciated. :confused Paul.

All the detail on rebuilding the pump is covered with lots of photos in section 6T in the '66 and '67 Chassis Overhaul Manuals; however, parts are very difficult to find.

Best bet is to send it to Bill Hodel in Canton, Ohio, (330) 832-0871 - he's the "guru" for Corvette A.I.R. systems. If you want, he can "gut" the pump (remove the vanes, so it's just an idler pulley); the most common failure mode for A.I.R. pumps is seizure of the vanes to the inside of the housing.
