2.7 - What Diameter Pulley???
I have at least two different size drive pulleys lying around. Can anyone tell me the right pulley no. or diameter of the drive pulley for a 2.7 with the 11 blade fan ?

PBH,
I just went through this myself. From 1969 to 1975, the pulley was 116mm (911.102.017.50). It changed to 131mm in 1976(911.102.017.04), I believe with the change to the five blade fan. Therefore, 2.7 engines had either 116mm or 131mm pulleys. If you have an 11-blade fan, I believe the older smaller pulley is correct. JP
