I'm replacing the timing chain on my 1982 900T. I've got the engine out of
the car and was doing well until I tried to remove the crank pulley bolt. It
laughs at my impact wrench and attemping to turn it with a breaker bar only
results in the engine turning. Is there a way to lock the flywheel short of
getting the special tool? Thanks for any advice

Not sure about the C900 but for 9000's there is a little port in the
bellhousing that will allow you to stick a stout screwdriver in and catch
the starter ring gear on the flywheel. Takes two people, one on the
screwdriver and one on the breaker bar.

Been there, done that, got the scraped knuckles to prove it!

If all else fails, you could wind it round until a piston is at BDC
and about to start it's compression stroke, then feed a load of rope
in through the spark plug hole.

Cheers,
