Dongfeng renault engine parts Gear chamber assembly D5010550477

Designed to maintain the engine’s lubrication system integrity, the assembly features a multi-layer sealing structure. The chamber body integrates a precision-machined sealing groove that accommodates a high-temperature-resistant FKM (Viton) rubber gasket, creating a leak-proof seal between the chamber and engine block. Additionally, each gear shaft opening is fitted with double-lip oil seals (with spring-loaded design) that prevent engine oil leakage while blocking dust, dirt, and coolant from entering the gear chamber. These seals withstand temperatures up to 180°C and maintain elasticity over 10,000 operating hours—far exceeding the lifespan of standard nitrile seals. Unlike poorly sealed chambers that cause oil loss or component wear, this design ensures consistent lubrication and protects internal gears from contamination-related damage

The gear chamber’s internal mounting surfaces and gear shaft bores are precision-machined via CNC processing, with a surface roughness of Ra ≤ 0.8μm and concentricity tolerance of ≤ 0.02mm. This ensures the chamber accurately positions the camshaft gear, crankshaft gear, and auxiliary drive gears (e.g., for the fuel injection pump), maintaining optimal gear meshing clearance (0.15–0.25mm) and minimizing noise/vibration during operation. The chamber also includes reinforced ribbing around gear mounting areas, enhancing structural rigidity to resist deflection under dynamic loads—preventing gear misalignment that could cause premature tooth wear or gear failure. Rigorous testing confirms the assembly maintains stable gear alignment even at the engine’s maximum RPM (up to 2,800 rpm), ensuring reliable power transmission to critical engine systems

Built to withstand the harsh conditions of engine operation (high temperatures, oil exposure, vibration), the chamber body is crafted from high-strength aluminum alloy (ADC12 grade) with T6 heat treatment. This material offers excellent thermal conductivity (dissipating heat from gears to prevent overheating) and corrosion resistance (withstanding long-term exposure to engine oil and coolants). The alloy’s tensile strength of 220MPa ensures the chamber resists cracking or deformation under the mechanical stress of gear rotation and engine vibration. Unlike cast iron alternatives, the aluminum construction reduces weight by 30% (improving overall engine efficiency) while maintaining comparable durability. Additionally, the chamber’s interior surfaces are coated with a wear-resistant ceramic composite, reducing friction between gears and chamber walls and extending the assembly’s service life to over 150,000 km

Engineered for efficient maintenance in automotive repair facilities, this assembly simplifies installation with user-friendly features. It comes with pre-assembled sealing gaskets, oil seals, and all necessary mounting hardware (high-tensile bolts with torque specifications matching Dongfeng Renault’s OEM standards)—no need for separate parts procurement. The chamber has laser-etched alignment marks that align with reference points on the engine block, guiding technicians to position it accurately in 45–60 minutes using standard torque wrenches. To guarantee quality, the product is manufactured in an IATF 16949 certified facility, with each unit undergoing strict inspections: dimensional checks via 3D coordinate measuring machines, pressure tests (to verify sealing integrity), and dynamic gear alignment tests. It also includes a 24-month warranty against manufacturing defects (e.g., material cracking, seal failure, or machining errors), providing Dongfeng Renault engine owners and repair shops with long-term peace of mind
