I did mine by pinning the flywheel at the locking location with a punch (works great) then I took a socket and breaker bar and 3 foot pipe and got on it. I had a piece of wood at the socket to hold it from coming off and stood on the pipe and it came loose. This was a correctly torqued bolt with loctite from Metric that I had to remove when broke one of the timing chain guides with an idoit move while removing the head
