Product Details

Flywheel Ring Gear by ATP®. Flywheel Tooth Number: 153. Size: 12.006" ID, 12.837" OD. The ring gear has teeth which engage with the starter motor allowing the engine to crank over and start. Repeated engagement with the starter results in worn or broken ring gear teeth. Once this is diagnosed, the ring gear must be replaced. ATP ring gears are designed to fit and function just like the original part to ensure durability and long life.

Features

  • Manufactured to meet or exceed original equipment specs
  • Eliminates grinding from damaged teeth
  • Increases starter drive life

The primary purpose of the flywheel is to store kinetic energy and preserve the rotating inertia of the engine through its cycles. The flywheel ring gear is also engaged by the starter drive pinion to make the electric motor turns the crankshaft starting a vehicle. The dual mass flywheel is used to eliminate engine vibrations preventing premature gear wear. Proper operation of both flywheels are critical for high performance of the vehicle. If your flywheels, dual mass flywheels, or related parts such as flywheel bolts, shims, or ring gears are cracked or damaged, turn to ATP products. They are designed and manufactured to meet or exceed the highest OE standards for quality, fit, and function. Made of premium quality materials, the products ensure superior durability for long-lasting service life.
