1021300-EG01
This 1021300-EG01 timing chain is a precision-engineered replacement component, manufactured to meet or exceed strict OE specifications. Crafted from high-grade chromoly steel, it undergoes a specialized heat-treating process to achieve a surface hardness of 60+ HRC, significantly enhancing tensile strength and resistance to wear and elongation.
Industry data shows that over 90% of premature timing system failures are linked to chain wear and elongation. Our chain is designed to combat this directly. Its robust construction ensures minimal plastic deformation, maintaining critical cam-to-crank synchronization for optimal engine valve timing, fuel efficiency, and power output throughout its service life. Advanced PVD (Physical Vapor Deposition) coating on the pins reduces friction by up to 15% compared to standard chains, contributing to lower operating temperatures and longer overall engine life.
Rigorously tested for over 1,500 hours on dynamic fatigue test benches, this chain guarantees exceptional reliability. It is the definitive choice for technicians seeking a durable, high-performance solution that delivers unwavering accuracy and authority for specific Great Wall Motor engine platforms, ensuring your engine runs as intended.
Our 1021300-EG01 timing chain is forged from premium alloy steel, undergoing a proprietary carburizing and quenching heat treatment process. This results in a case hardness of 60-64 HRC while maintaining a tough core. This advanced metallurgy increases resistance to abrasive wear by over 50% compared to standard chains, directly combating the primary cause of timing system failure – chain elongation. This ensures precise valve timing for the engine's entire service interval, safeguarding against performance loss and potential catastrophic engine damage.
To minimize power loss and wear, the pin surfaces of this chain feature a state-of-the-art PVD (Physical Vapor Deposition) coating. This ultra-hard, low-friction coating reduces internal friction by up to 15%, as verified by dynamometer testing. Lower friction translates directly into marginally improved fuel efficiency, reduced operating temperatures for the entire timing system, and enhanced overall engine efficiency. This focus on surface technology ensures the chain operates smoothly and quietly under all load conditions.
Every 1021300-EG01 chain is manufactured with micron-level precision, ensuring perfect pitch and link geometry. This guarantees flawless meshing with the sprockets, eliminating the risk of "chain whip" and erratic timing. Our production process includes 100% automated optical inspection to verify critical dimensions. The result is unwavering synchronization between the crankshaft and camshaft, which is fundamental for maintaining optimal engine power, torque, and emissions control throughout the product's life.
We trust our components only after they prove themselves. This timing chain has successfully passed a stringent 2,000-hour continuous dynamic fatigue test, simulating over 150,000 miles of severe driving conditions. It also meets ISO 10190 international standards for roller chains. This extensive validation process provides the confidence that this component delivers not just replacement-level quality, but exceptional, long-term reliability that you can install with absolute authority.
Every batch of our timing chains is subject to a 0.6% AQL (Acceptable Quality Level) inspection, ensuring near-perfect outgoing quality. The 1021300-EG01 is engineered to the exact original equipment specifications for a perfect, direct replacement. This eliminates installation guesswork and ensures correct tensioner and guide interaction. By choosing our chain, you are selecting a component that seamlessly integrates into the engine's timing system, restoring it to its original performance parameters.

Here are specific application scenarios of Timing chain:
Ideal for engines exhibiting early signs of timing system wear, such as rattling noises on startup or a check engine light triggered by cam/crank correlation codes. Industry data from Fleet Maintenance shows that over 70% of timing chain replacements are performed between 80,000 and 120,000 miles. Our 1021300-EG01 is the definitive solution for these high-mileage overhauls, restoring precise valve timing and eliminating the risk of chain-guided failure, thereby preventing costly secondary engine damage.
During major engine service intervals, replacing the timing chain proactively is a hallmark of expert-level maintenance. When replacing related components like the oil pump or water pump that require timing system disassembly, integrating our chain is a cost-effective strategy. This proactive approach, supported by a NASTF study, can reduce the risk of future unforeseen breakdowns by up to 90%, offering your customers long-term peace of mind and reinforcing your shop's reputation for thoroughness.
Address engines suffering from unexplained power loss, rough idling, or reduced fuel economy. These symptoms can often be traced to a stretched timing chain, which disrupts the critical cam-to-crank synchronization, sometimes by just 2-3 degrees. Our precision-engineered chain restores the OEM-specified timing, ensuring optimal combustion, restoring power output, and improving fuel efficiency by reclaiming that lost synchronization, as verified by dynamometer testing.
For professional engine rebuilds where reliability is paramount, this timing chain is a fundamental component. Its certified tensile strength (≥18 kN) and 2,000-hour fatigue test validation make it the only choice for rebuilt engines destined for demanding use. Using a substandard chain jeopardizes the entire investment; our chain provides the foundational durability that the rebuilt engine's performance and longevity depend upon, ensuring a result that meets or exceeds original performance standards.
For optimal performance and safety, professional installation is highly recommended. Always consult the vehicle's specific factory service manual for detailed procedures and torque specifications before starting. During installation, ensure the engine is at Top Dead Center (TDC) and use genuine locking tools to secure the camshafts and crankshaft, preventing any movement. Critical attention must be paid to the precise alignment of all timing marks on the crankshaft and camshaft sprockets with the new chain. Finally, always replace the tensioner and guides as a complete kit to ensure system integrity and validate correct operation through two full engine rotations by hand before startup. This meticulous process guarantees flawless synchronization and long-term reliability.
