PTO Output Shaft Fiat

This PTO Output Shaft (OEM # 4958986) is a critical component for Fiat tractors, designed to transfer power from the tractor’s engine to external implements such as mowers, tillers, or balers. Crafted from high-grade hardened steel, the shaft undergoes precision machining and heat treatment to withstand torsional stress, heavy loads, and harsh fieldwork conditions. Its splined design ensures seamless engagement with PTO-driven equipment, maintaining consistent power delivery for tasks like plowing, harvesting, or irrigation. The OEM-grade engineering guarantees exact dimensions and compatibility, reducing wear on drivetrain components and ensuring long-term reliability.

The shaft features a corrosion-resistant finish and reinforced construction to resist bending, shearing, and fatigue, even in muddy, rocky, or uneven terrain. Its smooth splines and balanced design minimize vibration and noise during operation, enhancing operator comfort and equipment efficiency. Whether replacing a worn shaft or upgrading during a PTO system overhaul, this component restores factory performance for Fiat tractors used in agriculture, landscaping, or construction.

Rigorously tested to meet Fiat’s OEM specifications (part # 4958986), this PTO output shaft is trusted by farmers and technicians. Proper installation requires alignment with the tractor’s PTO driveline, lubrication of splines with high-quality grease, and adherence to torque specifications. Always verify compatibility using your tractor’s model number, VIN, or consult Fiat’s service manual to ensure optimal fitment and performance.
