Crown Wheel & Pinion 14X47

This Crown Wheel & Pinion Set (OEM # 5005447) is engineered for Fiat tractors, delivering reliable power distribution between the differential and axle shafts. Featuring a 14:47 gear ratio (14 teeth on the pinion, 47 on the crown wheel), it optimizes torque multiplication for heavy-duty tasks such as plowing, tilling, or hauling. Crafted from heat-treated hardened steel, the set resists wear, pitting, and thermal stress, ensuring longevity in rugged farming environments. Precision tooth profiling minimizes noise and vibration, even under high loads, while maintaining smooth operation and efficient power delivery.

The OEM-grade design guarantees seamless integration with Fiat tractor differential systems, ensuring factory-level performance and reliability. The hardened steel construction enhances resistance to mechanical fatigue and deformation, critical for tractors operating in muddy, uneven, or abrasive terrain. Whether replacing worn gears or restoring a tractor during an overhaul, this 14X47 set ensures minimal downtime and maximizes drivetrain efficiency.

Rigorously tested to meet Fiat’s strict OEM specifications (part # 5005447), this crown wheel and pinion set is trusted by farmers and technicians worldwide. Applications include Fiat agricultural tractors used in fieldwork, construction, or forestry. 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 lifespan and performance.
