Terry Components Black Wrinkle Starter Motor for Harley Davidson 773590

The Terry Components Black Wrinkle Starter Motor (Part Number: 773590) is engineered for high performance and durability in Harley Davidson motorcycles. Built with a heavy-duty solenoid plunger, return damper, and springs reinforced with stronger components, this starter ensures reliable operation under demanding conditions. The clutch shaft and rollers are precision-ground and hardened, significantly extending service life and maintaining optimal engagement over time. All internal components are assembled with a specialized lubricant designed specifically for starter roller clutch applications, reducing wear and enhancing longevity.

The CNC-machined billet mounting noses are secured with aerospace-grade fasteners, providing robust attachment and reducing vibrations during operation. Each starter undergoes a comprehensive testing process on a dynamometer, which includes high-low voltage tests, stall torque measurement, solenoid engagement checks, amperage draw analysis, load testing, maximum RPM evaluation, and motor impulse waveform analysis. This rigorous testing guarantees consistent performance and reliability.

Equipped with a 4.4:1 gear reduction ratio, this starter produces approximately 46% more cranking torque than stock units, enabling it to start even the most powerful engines with ease. For optimal results, it is recommended to use the starter with Terry battery cables paired with a battery capable of delivering 300+ cold cranking amps, such as the Drag Specialties battery. Crafted in the USA, this high-performance starter is designed to meet the demands of serious riders and professional mechanics alike, ensuring dependable starting power for your Harley Davidson motorcycle.
