Dongfeng KL truck parts Flexible shaft with ball joint assembly 1703070-96375060-96355

Built as a critical link for mechanical control, this assembly delivers precise power transmission between the cab control lever and transmission selector. The flexible shaft features a multi-strand stainless steel core (316 grade, 7×19 strand structure) with high torsional stiffness, ensuring 99% torque transfer efficiency and minimal backlash (≤0.5mm) during gear shifts. The integrated ball joint (made of wear-resistant POM material) allows 360° rotation and ±15° angular deflection, adapting to the relative movement between the cab and chassis without restricting shaft movement. This combination eliminates gear shift lag, enabling drivers to engage gears with 20% less effort compared to standard shafts. For Dongfeng KL’s complex control layout, the shaft’s flexibility allows routing around chassis components while maintaining consistent transmission performance

Engineered for long-term reliability under repeated torsional stress, the 1703070-96375060-96355 assembly features a rugged dual-layer shaft design. The inner core is made of high-tensile stainless steel (tensile strength 1800MPa) that endures 2 million torsional cycles (equivalent to 500,000km of operation) without fatigue failure. The outer sheath is a low-friction Teflon (PTFE) tube with a nylon reinforcement layer, reducing friction between the shaft and sheath by 60% and preventing wear from dust or moisture. The ball joint’s bearing surface is coated with molybdenum disulfide lubricant, ensuring smooth rotation over 100,000+ gear shifts without additional maintenance. This structure avoids common issues like shaft seizing or breakage, which cause control failure and $1,200+ in repair costs

Optimized to withstand the extreme conditions of truck chassis operation, the assembly exhibits exceptional environmental resilience. The stainless steel shaft core is inherently resistant to rust and corrosion from road salt, rain, and diesel fumes, passing 2500-hour neutral salt spray testing (ASTM B117) with no degradation. The outer sheath’s nylon layer resists UV radiation and chemical damage from cleaning agents, maintaining structural integrity in temperatures ranging from -40℃ to 120℃—adapting to frigid northern winters and sun-exposed chassis. The ball joint’s housing is made of IP65-rated ABS plastic, blocking dust and water ingress, while its rubber seal prevents lubricant leakage. These features ensure reliable performance in construction sites, coastal regions, and snowy environments

This flexible shaft assembly is designed for efficient installation and long-term cost savings for Dongfeng KL operators. Its pre-assembled ball joint and mounting brackets allow a single technician to complete replacement in 30 minutes using standard tools—no specialized alignment equipment needed. The OE-compatible design ensures perfect fit with the transmission and control lever, avoiding the misalignment issues of aftermarket shafts that cause gear grinding (leading to $800+ in transmission repairs). The high-durability components extend the assembly’s service life to ≥300,000km—three times that of non-OE alternatives—reducing replacement frequency. By ensuring precise gear shifts, it reduces clutch and transmission wear by 25%, lowering maintenance costs. Backed by a 1-year/150,000km Dongfeng warranty, it provides reliable control transmission and predictable expenses for fleet operations
