If the crown is severely worn or has a missing tooth, the crown should be replaced. The old crown can be removed by making a cut between two teeth, and then knocking it down with a chisel.
Installing a new ring gear on the flywheel requires heating the ring to 204°C. This is done by uniformly heating the flywheel with a blowtorch until the heated surfaces acquire a light yellow tint.
Attention! Do not overheat the crown, otherwise its strength properties will be lost.
The crown has a beveled inner side of the teeth, which must face the starter. When the crown is warm enough, quickly replace it, tap if necessary, and cool naturally.
