Having recently come across some NOS rebuilt generators and needing one for my brother's Greenbriar project. I set out to understand what GM was doing with the generators. The following table was generated from parts books, assembly manuals and my barn of parts out back. This is not the last word on generator numbers as you see, there are gaps in table. Also GM did not always update the assembly manuals or parts books as well as they should have.

To aid in identification the armature's part number is stamped on it. Also all true Corvair armatures us a left hand nut to hold on the fan. This is not true for the alternators.

• 1960- Shorter then the later generator so the armature and fields are different.
• 1961-63- Basically we have two generators, one with terminals pointing up and one pointing back so the engine cover in the FC's and wagons have more clearance.
• 1964- GM figured out they could use the generator terminals pointing back for all the vehicles and added 5 more amps capacity by the use of a different armature.
• 1105135- Optional low speed cut-in generator was available 61-64 and apparently did not share anything with any of the other generators. This generator is considered quite rare and I think I can remember seeing one once at a national.
• 1102247 (16-U)- is a GM universal rebuilt replacement. From the one's we have still in the box they appear to be like the 1102227 except they have stickers instead of metal tags. Also GM painted the end frames black, which looks awful.

The 1951434 end frame is drilled for both generators but has only one mounting pin. Part numbers or casting numbers do not seem to be on the end frames. I have not finished my research on pulleys but one thing has come out. Early HI performance and Turbos used a different pulley then the standard Corvair. I'm not sure why.

The exploded picture of a generator is one you won't see in the regular GM Corvair parts book. It comes from the illustration book. You might want to copy it and put in your parts book.

^ Regulator 1119261 was used as a general replacement part for 60-63, except with generator 1102336, 1105135.
^ Regulator 1119635 was used as a general replacement part for generator 1105135.
