MCS Starter Gears

20 products — part of all Starter Gears

MCS starter gears give Harley-Davidson owners the replacement intermediate and idler gears needed to restore reliable, quiet engine cranking when the starter drive train begins to show wear. The starter gear train steps down the motor's speed and multiplies its torque to spin the engine ring gear — worn or chipped teeth cause the grinding, stuttering or over-running that riders hear as a classic sign of starter system wear. MCS produce their starter gears to Harley-Davidson tooth profile and material specifications for the main Big Twin electric start applications, covering Evolution and Twin Cam starters that have accumulated significant mileage. Replacing starter gears before a tooth breaks eliminates the risk of a failed gear jamming the starter or damaging the ring gear. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries MCS starter components alongside a comprehensive electrical and starting system range.
