Commenting on Howard's post, I have no problem with Loctite in its various guises, provided it is used wisely. Indeed, a number of modern chemical products help us in keeping our elderly cars on the road. For instance, the inner race of the rear main on my own car is secured to the crank with a blob of Loctite Bearing Fit, as it was at best a good push fit on the end of the crank, as the original bearing had spun. Fortunately, the replacement bearing is of the 'crowded roller type, so, if I have to minister to the bottom end again, pulling the outer race will cause all the rollers to fall out, so i could still get the crank out and sort out any recalcitrance on the part of the inner race on the bench.
Most Loctite materials also weaken with heat (about 300C if memory serves me correctly), but you need a really good plumbers brazing torch (like a Rothenberger or similar) to get enough heat onto a flywheel.
My own experience with Loctited flywheels was from many years ago, when I had my special. In my youthful enthusiasm, I loctited the flywheel to the end of the crank, and, subsequenty, when I tried to remove it to reline the clutch, managed to pull the thread out of one of the threaded holes in the flywheel that supports the flywheel puller. You can imagine the fun I had getting the flywheel off after that!
