Ring gear is worn and its time to flip it over.
Had something to rotate the flywheel on when heating the ring gear. You take what you have LOL.
Heating and some tapping with the hammers.
Flywheel and ring gear cleaned up in the media blast cabinet.
Some small steel wires to keep the ring gear in the right place but preventing the heat from getting to the flywheel.
Some heat and some light hammer tapping and its in place.
