R4 / 6 / 12 Flywheel Ring Gear 8200279345 7725147147 702252428 119 Teeth

1. The ring gear part is made of standard 45# alloy steel and high-frequency quenching process. The hardness of the tooth part can reach 48-58HRC, which makes the product more heat-resistant, wear-resistant and durable.

2. Our company uses fully automatic CNC machine tools, machining centers, quenching machines and other equipment in the processing process to ensure better processing accuracy of the products, which can reach the dimensional accuracy of the original parts of the automobile factory, so that the sound of the products is smaller and more Stablize.

3. The inspection adopts 3-D Measuring/Metallurgical Micro-test/Hardness test/Tension test and other equipment to ensure that there will be no defective products in the factory.

4. The ring gear's teeth are machined to high tolerances to ensure smooth and reliable engagement with the starter motor's pinion gear. The ring gear's tooth count is carefully calculated to achieve the desired gear reduction ratio for efficient engine starting.
