Lexus RX350 Starter Motor

Lexus RX350 Starter Motor provides the first twist to get the V6 engine started by converting electricity from the battery to the engine's crankshaft. The Starter Motor consists of a solenoid connected to the battery, gauge wiring, and an armature with field coils or permanent magnets, so when current passes through it, the armature revolves and pushes a pinion into the flywheel after the engine fires up and a clutch that backs it off, which is overrunning. This Starter Motor assembly is also dependent upon a Lexus ignition triggered relay and a neutral safety switch to prevent cranking when the shifter is not in the park or neutral position. Early Lexus RX350 models use a direct drive configuration, whereas later versions use a gear reduction Starter Motor, which allows a gear set to be applied between armature and pinion, increasing the torque and reducing the size. Thus, all Lexus Starter Motors guarantee RX350 drivers quick and safe starts from their Lexus RX350 every day. The Starter Motor is essential for reliable performance.
