Crown Wheel & Pinion 14X47 (Short)

This Crown Wheel & Pinion Set (OEM # 5003937) is engineered specifically for Fiat tractors, delivering reliable torque transfer between the differential and axle shafts. With 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. The "Short" designation indicates a compact design tailored for specific Fiat tractor models, ensuring compatibility with limited-space differential housings. Crafted from heat-treated hardened steel, the set resists wear, pitting, and thermal stress, making it ideal for rugged farming conditions.

Precision-machined tooth profiling ensures minimal noise, vibration, and backlash during operation, even under high loads. The hardened steel construction enhances longevity, while the OEM-grade engineering guarantees seamless integration with Fiat’s differential systems. This set is critical for maintaining drivetrain efficiency, reducing downtime, and preventing premature failure in demanding environments. Whether replacing worn components or restoring a tractor during an overhaul, this 14X47 gear set ensures factory-level performance and reliability.

Rigorously tested to meet Fiat’s OEM specifications (part # 5003937), this crown wheel and pinion set is trusted by farmers and technicians. Applications include Fiat tractors used in agriculture, forestry, or construction. Always verify compatibility using your tractor’s model number, serial code, or consult the service manual. Proper installation, lubrication with high-quality gear oil, and adherence to break-in procedures are essential for maximizing gear life and performance.
