79 crankshaft pulley bolt direction

[barnesjtsl]

79 Spider 2000.

Is the crankshaft pulley bolt righty tighty lefty loosey? Or is it reverse thread?

I'm surprised that I have searched multiple terms and can't find a definitive answer.

Thanks everyone for all the help over the years!

barnesjtsl,

If it has it's original engine -- or -- an engine from 1979 in it, then it is righty-tighty, lefty-loosey.
It is likely going to be on there very tight, so be ready to exert some effort removing it.

Thank you. Yes, it is the original engine.

Got an air impact wrench and chain wrench so I don't think it will be a problem.

Thanks again,

If your crankshaft pulley is secured by a nut, then it's right-hand (normal) threaded. If your pulley is secured by a bolt, as was the case with the last years of Pininfarina spider production, then that beast is a left-hand (reverse thread) setup.
