A starter ring gear, sometimes called a starter ring or ring gear, is a 

medium carbon steel ring with teeth that is fitted on the periphery of a 

flexplate or flywheel of an internal combustion engine, mostly for automotive 

applications.

The teeth of the starter ring are driven by the smaller gear (the pinion) of the

 starter motor. The primary function of the starter ring is to transfer torque

 from the starter motor pinion to the flywheel or flexplate to rotate the engine to 

begin the cycle.

The starter ring gear is most commonly made by forming a length of square

 or rectangular steel bar into a circle and welding the ends together. There 

then follow various heat

treatmentlike normalising and tempering and machining operations, 

including the machining of the teeth and finally a heat-treatment operation. The teeth of the starter ring need to be hardened in 

order to increase their strength and resist wear. The normal hardness at 

pitch circle diameter is 45-55 HRC. The hardness at the root of the teeth is about 40 HRC and at 2 

mm below root the hardness is 35 Hrc max. The body of the ring is generally 

left untreated.

Engines with manual transmission usually have a heavy flywheel, typically 

5 to 10 kg of cast iron, with the starter ring gear shrunk onto the outside. 

This is done by heating the ring to around 200 °C to expand the ring which is then placed onto the flywheel, hold the ring 

gear with hydraulic pressure of 5 kg/cm2 for 1 min and allowed to cool the 

ring gear.The starter ring is thereby firmly attached to the flywheel.
