What Is A Starter Motor Replacement

Before the advent of the starter motor, various methods were used to start engines, including wind-up springs, gunpowder cylinders, and human-powered techniques like a removable crank handle that engaged the front of the crankshaft, pulling on an airplane propeller or pulling a cord wound around an open-face pulley. The hand-crank method was commonly used but was inconvenient, difficult, and dangerous. Engine behavior during starting could be unpredictable, with the engine potentially kicking back and causing sudden reverse rotation. Many manual starters included a one-directional slip or release feature so that once engine rotation began, the starter would disengage. However, in the event of a kickback, the reverse rotation of the engine could suddenly engage the starter, causing the crank to unexpectedly and violently jerk, possibly injuring the operator. This led to the invention of electric starters.

The starter motor is an electric motor that turns over or “cranks” the engine to start. It includes a powerful motor and an attached starter solenoid. When you turn the ignition key to the START position or press the START button, the battery voltage flows through the starter control circuit, activating the starter solenoid if the transmission is in Park or Neutral. The starter solenoid then powers the starter motor and pushes the starter gear forward to mesh with the engine flywheel, which is connected to the engine crankshaft. The starter motor spins the engine crankshaft, allowing the engine to start. In cars with push-button start, the system disengages the starter as soon as the engine begins running. At Advanced Mobile Mechanics, we handle starter motors daily for all makes and models. Suppose you suspect your car needs a new starter motor.
