Dongfeng GX truck parts Push disk rubber sleeve repair kit K201731K50

The kit includes all necessary parts to fully restore the push disk’s functionality, eliminating the need to source individual components. Core items include: 2 high-quality rubber sleeves (primary and backup, made of oil-resistant compound), 4 corrosion-resistant stainless steel washers (for even load distribution), 2 high-tensile steel retaining rings (to secure the sleeve in place), and a tube of high-temperature grease (15g, formulated for push disk lubrication). Additionally, it comes with a detailed instruction sheet featuring step-by-step diagrams of the Dongfeng GX’s push disk assembly, guiding technicians through disassembly, sleeve replacement, and reassembly. This comprehensive set ensures a complete, long-lasting repair in one session, reducing truck downtime for fleet operators

The rubber sleeves in the kit are crafted from premium nitrile-butadiene rubber (NBR) with added polymer modifiers, specifically designed to withstand the harsh conditions of Dongfeng GX’s push disk operation. This material resists degradation from engine oil, transmission fluid, and grease—common contaminants that cause premature wear of standard rubber sleeves. It maintains elasticity in extreme temperatures ranging from -40°C (cold winters) to 120°C (engine bay heat), avoiding brittleness in cold weather or softening in hot conditions. The rubber’s tensile strength of 18 MPa ensures it can endure the repeated compression and expansion of push disk movement (up to 50,000+ cycles) without cracking or tearing, extending the push disk’s service life by 2–3 times compared to low-quality sleeves

Engineered to streamline push disk repair (even for technicians with limited experience), the kit features user-friendly design elements. The rubber sleeves have a pre-lubricated inner surface that eases installation onto the push disk’s metal shaft, reducing the risk of damage during fitting. The retaining rings are designed with a split opening and easy-grip tabs, allowing them to be installed or removed with standard pliers (no specialized tools required). The instruction sheet includes clear labels for each component and highlights critical torque values (e.g., 8–10 N·m for washer fasteners) to ensure proper assembly. These features reduce the average repair time by 40% compared to generic kits, enabling faster vehicle turnaround for busy repair shops

By replacing worn rubber sleeves, the kit fully restores the push disk’s original performance—critical for maintaining smooth clutch/transmission operation in Dongfeng GX trucks. Worn sleeves often cause push disk play, leading to clutch slippage, uneven gear engagement, or transmission noise; the kit eliminates these issues by restoring proper alignment and damping. The NBR rubber also acts as a vibration damper, reducing noise and vibration transfer from the push disk to the cabin, improving driver comfort. The kit complies with international automotive standards (ISO 815 for rubber materials, SAE J200 for performance) and is manufactured in an IATF 16949 certified facility. Backed by a 18-month warranty against manufacturing defects (e.g., rubber cracking, retaining ring failure), it provides Dongfeng GX truck owners with reliable push disk performance and long-term peace of mind
