Dongfeng GX front cover Secondary lock assembly 5301612-C6200

The part number 5301612-C6200 is a unique official identifier authorized by Dongfeng, distinguishing this genuine front cover secondary lock from counterfeit or low-quality alternatives. By inputting this number into Dongfeng’s official parts database, users can access comprehensive details: production batch, manufacturing date, quality inspection records (e.g., lock engagement and durability tests), and authorized supply channels—enabling full lifecycle traceability. This traceability is critical for safety: if the secondary lock fails (e.g., unable to engage), the part number helps track production defects to prevent front cover accidental opening while driving. For workshops, it simplifies inventory management and procurement, ensuring accurate selection of GX-specific secondary locks. The number is clearly etched on the lock’s housing, remaining legible even after long-term exposure to engine heat and dust, facilitating easy authenticity checks

As a critical safety component, this secondary lock assembly provides redundant protection for the Dongfeng GX’s front cover, working with the primary lock to prevent accidental opening during driving. It features a spring-loaded locking pawl that automatically engages with the front cover’s striker plate when the primary lock is closed, creating a dual-lock barrier. The pawl requires a specific pull force (30-40N) from the front cover release cable to disengage—preventing accidental release from vibration or road bumps. Additionally, the lock has a visual engagement indicator (a small tab that protrudes when locked) to help technicians confirm proper installation. Tested under simulated extreme conditions (vehicle vibration at 60-120km/h, temperature cycles of -30°C to 85°C), the secondary lock maintains reliable engagement, ensuring the front cover stays securely closed, even if the primary lock malfunctions

To withstand the harsh engine compartment environment (high temperatures, vibration, and oil exposure), this secondary lock assembly uses high-quality, heat-resistant materials. The lock body is made of heat-stabilized PA66 engineering plastic (continuous use temperature: -30°C to 120°C), resisting deformation from engine heat. The locking pawl and striker plate are made of high-carbon steel (S45C) quenched to HRC 45-50, enhancing wear resistance—after 20,000+ lock/unlock cycles, wear is <0.05mm. The internal spring is made of stainless steel (304), maintaining elasticity and resisting rust from moisture or oil. The linkage rod connector is coated with wear-resistant nylon, reducing friction and preventing cable binding. Every unit undergoes 100% quality testing: high-temperature endurance tests (1000 hours at 100°C), lock cycle tests, and corrosion resistance tests, guaranteeing a service life of 8-10 years

Designed for efficiency, this secondary lock assembly features easy installation that integrates seamlessly with the GX’s existing front cover lock system. It uses the original mounting brackets—align the lock body with the pre-drilled holes on the front cover frame, fasten with 2-3 self-tapping screws (included), and connect the linkage rod to the primary lock release cable (no cable modification needed). The assembly has clear alignment marks (e.g., “FRONT” labels) to ensure correct orientation, and the linkage rod length is pre-adjusted to match the GX’s specifications—no on-site trimming required. A bilingual (English/Chinese) installation manual is included, providing step-by-step instructions and tips for verifying lock engagement. Even novice maintenance personnel can complete installation in 20-30 minutes, ensuring the secondary lock works in perfect sync with the primary lock, maintaining the front cover’s original opening/closing feel
