This Bevel Gear Set (OEM # 5003937) is a critical component for Fiat tractor differentials, designed to transfer power efficiently between the drive shaft and axle. Featuring a 14:47 gear ratio (14 teeth on the pinion, 47 on the crown wheel), it provides optimal torque multiplication for heavy-duty tasks like plowing, tilling, or hauling. Crafted from heat-treated hardened steel, the gears resist wear, pitting, and thermal stress, ensuring longevity in harsh agricultural environments. Precision-machined tooth profiles minimize noise and vibration, while the OEM-grade design guarantees seamless integration with Fiat’s drivetrain systems.

The set includes a crown wheel (ring gear) and pinion gear, engineered to exact factory specifications for smooth meshing and minimal backlash. The hardened steel construction enhances resistance to mechanical fatigue, critical for tractors operating in muddy, rocky, or uneven terrain. Ideal for repairs or differential overhauls, this gear set restores factory performance and reliability, reducing downtime during peak farming seasons. Applications include Fiat tractors used in agriculture, construction, or forestry, where robust differential performance is essential.

Rigorously tested to meet Fiat’s OEM standards (part # 5003937), this bevel gear set is trusted by technicians and farmers worldwide. Proper installation requires precise alignment, lubrication with EP-90 gear oil, and adherence to torque specifications. Follow the manufacturer’s break-in procedure (e.g., gradual load increase) to maximize lifespan and ensure optimal gear contact patterns.
