Infiniti Q45 Starter Drive Gear provides the initial force that activates the engine and enables starting with every turn of a key. This Starter Drive Gear is made specifically for the luxury sedan family. It is located at the rear of the starter motor, sliding into the flywheel within milliseconds. From that position, it cleanly withdraws to protect the various components from kickback. As early and later Q45 editions evolved, two distinct Starter Drive Gear designs emerged, using either a classic Bendix inertia or a modern roller clutch design, both tested under high compression starts not to slip. Whether they drive a 1990s Q45 sedan or a later Q45, each driver will enjoy the same confidence. This is because each Starter Drive Gear has been matched to factory specs. This guarantees tooth alignment with any production flywheel. Due to the superior quality of its heat treated steel, which helps its resistance to wear, the overrunning clutch variant even freewheels once the engine fires, cutting drag and improving efficiency. The reverse torque then cannot crack the housing and is therefore safer. The Starter Drive Gear manufactured by Infiniti is subjected to stringent quality control standards throughout its assembly to ensure each unit is balanced and properly lubricated so that it can make the voltage from the battery cause the crankshaft to rotate. Moreover, this process happens with the least amount of current draw possible. The reliability of this starter unit pays off after years of stop and go commuting as it ensures the starter replacement interval is much longer and keeps the Q45 on the road and not in the garage. These material selections allow the Infiniti powertrain to crank after long storage. This is made possible because the Starter Drive Gear remains rust free and instantly couples to the ring gear upon start command. Each sedan in the Infiniti line boasts characteristics of durability, quiet engagement, and performance of the factory Starter Drive Gear. Every Infiniti Q45 relies on its Starter Drive Gear when seconds truly matter.
