Speed Gear Fiat

This Speed Gear (OEM # 5102789) is a critical component in Fiat tractor transmissions, responsible for regulating speed ratios and ensuring smooth power delivery across different operational gears. Crafted from heat-treated hardened steel, the gear undergoes precision machining to withstand high torque, abrasion, and repetitive stress during demanding tasks like plowing, tilling, or hauling. Its advanced tooth profiling minimizes noise and vibration, while the OEM-grade design guarantees seamless meshing with adjacent gears and synchronizers, maintaining transmission efficiency and reducing wear over time.

The gear’s hardened steel construction provides exceptional resistance to pitting, deformation, and thermal fatigue, ensuring longevity even in rugged agricultural environments. Designed for compatibility with specific Fiat tractor models, it plays a key role in enabling operators to shift smoothly between speeds, optimizing performance for fieldwork, road travel, or heavy hauling. Whether replacing a worn gear or rebuilding a transmission, this component restores factory-level reliability and precision.

Rigorously tested to meet Fiat’s OEM specifications (part # 5102789), this speed gear is trusted by farmers and technicians. Proper installation requires adherence to torque specifications, alignment checks, and lubrication with high-quality gear oil. Always verify compatibility using your tractor’s model number, VIN, or consult Fiat’s service manual to ensure seamless integration.
