Normal thread but it's on VERY tight (and so it should be). I use starter motor power to get it off!  Shocked

If it did not let go on starter motor then you can heat it with some gas torch and then cool it with water  - make few cycles and then try to undo the bolt

On examination the bolt head has a large capital 'L' on it, must surely indicate L/H thread?

Sorry Steve, don't know anything about Stradas (although I did have a 65CL Bianca many years ago!  Embarrassed  Wink ) and I am not sure what you mean with left hand and right hand threads (I always use my right hand to undo bolts  Grin). But I can say with 100% certainty that on a 131 engine you would undo the crankshaft front pulley nut by turning it anti-clockwise.

Hi Eugene,
I would be lying if i said i didnt scrape a knuckle or two! Angry
Pulley is away having a distance piece machined so as to fit a trigger wheel.
The Omex electronic ignition system is wired in, just the throttle bodies/injectors and fuel rail to come.  i should get her running when im home (Spain) in September.

38mm socket, normal style of thread ie clockwise to tighten.

remove sump, engine upside down - jam crank with 2 small pieces of wood.

Remove nut with compressor driven windy gun or electric nut gun. Shocked


You will never get enough purchase on it with bars etc, it all just moves.
