Once the 5 flywheel bolts are off the flywheel pulls off but it is tight fit, not a pressed fit, just tight. I use an old Plomb 4021 puller. The problem is you can't really get your arms in there for a good yank. Sometimes a little wiggling helps.
Best crank block of all time. It's not easy really to move the crank and cause the bearing shim to move but since the consequences of having done that are so bad the restraint is highly recommended.
