Dongfeng GX truck parts Guide pin seal repair kit K152500K50

The kit includes all necessary parts to fully repair and restore guide pin sealing functionality, eliminating the hassle of sourcing individual components. Core items include: high-temperature-resistant FKM (Viton) seals (2 pieces, for primary and secondary sealing), low-friction PTFE-coated bushings (2 pieces, to reduce guide pin wear), corrosion-resistant stainless steel washers (4 pieces, for even load distribution), and a tube of high-performance lithium-based grease (10g, formulated for guide pin lubrication). Additionally, it includes a pair of disposable gloves and a detailed instruction sheet with step-by-step diagrams. This comprehensive set ensures technicians have everything needed for a one-time repair, reducing downtime and avoiding incomplete fixes that could lead to reoccurring seal failures

Each component in the kit is crafted from premium materials to withstand the harsh conditions of Dongfeng GX’s guide pin operation (exposure to brake heat, road salt, mud, and constant movement). The FKM seals resist temperatures up to 200°C (critical for brake caliper guide pins near hot brake discs) and maintain elasticity over 50,000+ operating cycles, far exceeding the lifespan of standard nitrile seals. The PTFE-coated bushings reduce friction between the guide pin and housing by 40%, minimizing wear and extending the guide pin’s service life. The stainless steel washers (304 grade) prevent rust and corrosion, while the lithium-based grease offers water resistance and remains stable in temperatures ranging from -30°C to 150°C. This material combination ensures the repaired guide pin maintains reliable sealing and smooth operation for over 80,000 km

Engineered to simplify guide pin repair (even for technicians with limited experience), the kit features user-friendly design elements. The seals have a pre-lubricated surface that eases installation into the guide pin housing, reducing the risk of damage during fitting. The bushings are marked with alignment notches that match the housing’s keyways, ensuring correct orientation without guesswork. The instruction sheet includes clear, labeled diagrams of the Dongfeng GX’s guide pin assembly, highlighting where each component fits and specifying torque values for fasteners (if applicable). Additionally, the grease tube has a precision nozzle that allows controlled application directly to the guide pin, avoiding over-greasing or mess. These features reduce repair time by 30% compared to generic kits, enabling faster vehicle turnaround for fleet operators

To guarantee performance and safety, the kit undergoes rigorous quality control measures at every production stage. All components are manufactured in an IATF 16949 certified facility, with each seal and bushing tested for dimensional accuracy via 3D scanning and for material integrity via pressure and temperature resistance tests. The kit complies with international automotive standards (ISO 6194 for hydraulic seals, SAE J310 for lubricants), ensuring compatibility with Dongfeng GX’s safety and performance requirements. A 24-month warranty covers the kit against manufacturing defects (e.g., seal leakage, bushing deformation, or grease degradation), providing peace of mind for repair shops and truck owners. By restoring proper guide pin sealing, the kit prevents contaminants from entering the pin housing (which could cause seizing or component failure) and maintains the vehicle’s braking or suspension performance—critical for safe operation in heavy-duty and long-haul conditions
