High-performance flywheels, gear rings, control cables, and hydraulic systems built to specifications.
An engineering analysis on safety margin, structural rigidity, and precision engine timing operations.
In modern powertrain engineering, securing the crankshaft while torque-critical bolts are tightened or loosened is one of the most vital tasks for mechanics and OEMs alike. The installation of dual-mass flywheels (DMF), single-mass flywheels, harmonic balancers, and timing belts requires locking components that can withstand up to 350+ Nm of torsional resistance. Standard improvisation methods, such as using slot screwdrivers or dynamic pry bars, risk damaging gear teeth profiles, causing stress fractures on cast alloy engine casings, and altering sensor alignment rings.
Our CE certified flywheel lock tools are precision engineered to mesh perfectly with the teeth profile of engine ring gears. By distributing the shear stress evenly across multiple gears, our tools eliminate point-load concentration, guaranteeing safe torqueing of the crankshaft pulley bolts without distorting critical engine clearances.
As internal combustion engines evolve alongside hybrid powertrains, the dimensional tolerances of flywheels continue to shrink. Future driveline components utilize lighter, ultra-high-tensile steel, which requires next-generation timing locks. Our technical roadmap focuses on the integration of carbon-molybdenum alloy matrices that yield higher tensile strength (exceeding 850 MPa) while keeping the tool lightweight and highly ergonomic.
Whether servicing transcontinental shipping fleets, commercial logistics trucks, or construction excavators, downtime is the largest overhead expense. Our flywheel lock tools are developed in tandem with top-tier truck manufacturers (including Hino, Scania, Mercedes-Benz, and Sinotruk), enabling fleet managers to streamline engine repair times by up to 35%.
By providing direct compatibility with various engine blocks, TVC Auto mitigates the risk of crankshaft timing drift, which is a major contributor to post-maintenance engine knock and timing sensor mismatch codes. Our tooling systems act as a protective barrier for high-value logistics fleets, ensuring predictable and clean maintenance workflows.
Zhejiang TVC Auto Co., Ltd. was established to become an independent, specialized company focused on manufacturing clutch parts. After more than ten years of continuous effort, the company has grown into a significant player in the industry. Led by renowned experts, researchers, and senior engineers in clutch manufacturing, we take responsibility for technology, quality management, product development, and sales.
Our management team, with expertise in manufacturing, production, logistics, procurement, and equipment management, has built three major product lines (light, medium, and heavy) covering a wide range of products.
Zhejiang TVC Auto Co., Ltd. specializes in the research, development, production, and sales of clutches for light, medium, and heavy trucks. Our products are suitable for various truck models and use high-quality raw materials from reputable suppliers to ensure top standards. We manufacture over 90% of our clutch parts in-house, all of which pass national authority testing.
We are committed to delivering products on time with high efficiency, and our prices are highly competitive in the market. From the beginning, we have implemented the ISO/IATF16949: 2016 quality control system, demonstrating our dedication to quality. Our products are well-recognized in both domestic and international markets.
