Dongfeng VR Transmission control lever and support assembly 1703025-KC100

The 1703025-KC100 assembly features an ergonomically optimized control lever with a non-slip rubber grip (textured surface for enhanced hand traction) and a tailored length/angle (700-750mm lever length, 15-20° tilt from vertical). This design reduces driver fatigue during extended shifts (e.g., 8+ hour driving sessions) by aligning with natural hand movements and minimizing wrist strain. Additionally, the lever’s internal linkage uses precision-machined pivot points and low-friction bushings (made of oil-impregnated bronze) to ensure smooth, backlash-free shifting—allowing drivers to engage gears with minimal effort and clear tactile feedback. The optimized shift throw (80-100mm between gears) further enhances precision, reducing the risk of missed shifts or gear grinding in high-pressure scenarios (e.g., uphill acceleration)

The assembly’s support frame is crafted from high-grade carbon steel (Q235 or equivalent) with a powder-coated finish, delivering exceptional structural rigidity and corrosion resistance. The steel frame undergoes robotic welding to ensure uniform joint strength, withstanding the constant mechanical stress of daily shifting (up to 500+ shifts per day) and cab vibration from rough road surfaces. Unlike flimsy aluminum or plastic supports, it resists bending, deformation, or cracking—even under accidental impacts (e.g., driver leaning on the lever). The powder-coat finish (thickness: 60-80 μm) also protects against rust and scratches from dust, moisture, and road debris, ensuring the assembly maintains structural integrity for 500,000+ km of operation

The D5010224535 assembly incorporates safety features to prevent accidental gear disengagement or unintended shifts. It includes a factory-calibrated detent mechanism (a spring-loaded ball bearing that locks into gear-specific notches) that holds the lever firmly in the selected gear, even during sudden cab jolts (e.g., hitting potholes). For transmissions with reverse gear, the assembly may also include a reverse lockout feature (a push-down or lift-up mechanism) that prevents accidental reverse engagement while moving forward—reducing the risk of transmission damage or vehicle instability. Additionally, the lever’s grip is designed with a non-slip surface to ensure secure handling in wet conditions (e.g., rainy weather), further enhancing driving safety

Designed for easy, efficient installation, the 1703025-KC100 assembly includes all OEM-matched hardware—such as mounting bolts, lock washers, and linkage pins—that align perfectly with the Dongfeng VR’s cab floor and transmission linkage points. No additional drilling, welding, or modification is required; technicians can complete the replacement by removing the old assembly’s fasteners, disconnecting the linkage, and securing the new assembly in place (typically 1-2 hours). The pre-assembled design (lever, support frame, and linkage come fully assembled) eliminates the need for time-consuming component alignment, ensuring the assembly works seamlessly with the VR’s transmission system immediately after installation. This reduces vehicle downtime, critical for fleet operators relying on Dongfeng VR trucks for time-sensitive deliveries
