My error, you guys were right, it's a 36mm. I have learned that the measured diameter of a 36mm socket is greater than 36mm!

Russ - it's a 36mm bolt, but try Paul's way. It's not quite as precise because of gear lash, but it works fine. Also, it should be in 1st gear.

The socket I use on my '76 308GTB is 36 millimeters. It's possible that they vary between model years.

Russ if you leave the car in gear and jack up both wheels you can rotate the engine by turning the wheel hub, so no need of a wrench. Just another method, if you don't have the socket.

What size is the big bolt that secures the pulley to the end of the crank? Looks like 40mm but need to be sure before I buy another tool I don't have a use for.
