Husqvarna Shaft OEM #505168901

Restore precise power transmission and smooth operation to your Husqvarna outdoor power equipment with the genuine OEM Shaft (Part #505168901). This factory-original shaft component is a critical mechanical element — transmitting rotational force from the engine or drive system to the cutting head, gearbox, or adjoining assembly it serves. Engineered for durability and precision, shafts are essential components for Husqvarna equipment, designed to meet strict Husqvarna quality standards and crafted to withstand rigorous outdoor use, ensuring smooth power transfer and extending the lifespan of the equipment.

Also Known As:

• Drive Shaft / Inner Shaft / Flexible Shaft
• Transmission Shaft / Output Shaft / Intermediate Shaft
• Inner Drive / Shaft Assembly Component

Part Number Family Context: This shaft shares the “505” part number series with Spacer Sleeve #505173301, Washer #505173001, and Washer #505169801 — strongly suggesting these components work together within the same mechanical assembly on Husqvarna handheld outdoor power equipment. When replacing this shaft, inspect all related hardware in the same assembly for wear and replace as needed.

Key Features:

• Genuine OEM Part – OEM Certified: Guaranteed compatibility with Husqvarna outdoor tools for seamless installation — manufactured to exact factory specifications for correct diameter, length, and end geometry
• Critical Power Transmission – Delivers seamless power transfer for smooth and efficient operation between the engine and the cutting or drive system it connects
• Ensures reliable torque transmission between engine and cutting components, designed to maintain optimal performance under demanding outdoor conditions
• High Durability: Manufactured with robust materials to resist wear and mechanical stress — built to withstand the high rotational speeds, vibration, and torque loads of Husqvarna handheld outdoor power equipment
• Precision Geometry – Exact shaft diameter, length, keyway, and end spline or coupling profile are critical to safe engagement with adjacent bearings, gearboxes, and drive couplings — only a genuine OEM shaft provides these tolerances
• Reduces wear and vibration, improving the longevity and efficiency of your machinery
• Sold Individually – Order the exact quantity needed for your repair
• Direct-Fit Replacement – Engineered to the same dimensional specification as the original for drop-in installation without modification

Why Genuine OEM Shafts Matter: A shaft that differs in diameter, length, or end profile — even slightly — can cause misalignment, bearing overload, excessive vibration, premature wear of the gearbox or cutting head, and in severe cases, catastrophic failure of the drive system. Our OEM shafts combine expert craftsmanship and genuine materials, ensuring reliable, long-lasting performance that keeps your Husqvarna equipment running like new. Aftermarket substitutes may not meet the original dimensional tolerances, material hardness, or surface finish specifications required for safe, efficient power transmission.
