986 3.2 home engine rebuild

[OldManMo]

After degreasing the crank and giving it a bath I checked the main journals and all were 60.0mm using a digital calliper. I have a micrometer somewhere and will dig it out to double check , but with all honesty I don’t know if this is good or bad.

Lots if posts from people have measured theirs but there appears to be nothing published as to factory spec by Porsche. Without buying a new crank, is anyone aware of the factory specs for both journals?

Porsche never published any internal clearance info on these engines as they didn't want anyone to work on them in the field. They didn't even publish engine internal torque specs. That is why Jake Raby's information is so important.

Thanks JFP in PA for confirming and replying, your help is very much welcome and appreciated. Got Jakes torque specs which is a God send as are his DVDs so far.

So the only way anyone can find out what the default factory spec for each journal is to buy a new crank and measure them and then publish them on the net to help others. Don’t really want to spend the money as my crank as far as I can see looks ok though I could be wrong as I don’t know what the original specs are

Nice (British sarcasm)
