FlyWheel Ring Gear

Generally we use a masonery or carbide drill bit and drill righ between two teeth.. make a decent pilot hole.. say.. using a 1/4 bit.. but don't get into the flywheel. Then take a cold chissle and give it a good whack on the small bridge on either side of the hole,.. should pop it right apart. Occasionally you run into a flywheel that was loose..and someone looked to save a few bucks and will have made about 4 1" welds evenly spaced around the flywheel to hold it on. in this case you have to use an angle grinder and grind the weld out. Try to only cut it flush to the fly wheel, and then do the drill and chissle trick.. that way you don't have to v-cut the weld dep into the flywheel. The thin brittle area left from you cutting it flush should crack easilly when you split the ring gear. After removal very lightly remove the bur from each weld.. but don't dress the rest of the flywheel, as these are interference fit.

Getting them off is easier than getting them on. Some people try baking them in an over on 400-500 degrees for about a half an hour and then IMMEDIATLY drop them on the flywheel and tap down flush real quick with a hammer. You have about um.. 5 seconds to do this before the metals expand/contract form contact.

If you have a rosebud tip for your torch.. this becomes easier.. just heat the ring ear evenly and then drop it on.. don't get it red hot.. In fact.. probably just hot enought right before you see it turn is fine.
