  View original topic: Looking for info on stock oil pump sizes through the years

I have been doing some searching on here but have not had much luck finding comprehensive list of various stock oil pump sizes through the years. Is there a list out there or sources (Bentley etc) where I could look up what the original sizes/part numbers etc are.

"How to Rebuild Your VW Air-cooled Engine " page 56.

Type 1

17mm 60-67
19mm 68-69
24 mm 70
26mm 71-79

24 & 26mm are for dished cam gear. I don't have p/n handy. Just happened to have the book out today referencing head numbers.
