The genuine Mc 13 cylinder liners with OEM number 202V01201-0460 are engineered to provide exceptional wear resistance, precise dimensional stability, and superior heat transfer for SINOTRUK Sitrak heavy‑duty trucks equipped with the MC13 engine platform. Manufactured from high‑strength centrifugally cast iron with advanced surface treatment, these wet‑type liners ensure optimum piston ring sealing, reduced oil consumption, and extended engine overhaul intervals. As a foundational component within the Sinotruk sitrak parts portfolio, the 202V01201-0460 Mc 13 cylinder liners guarantee factory‑grade fitment, superior durability, and the reliability required for millions of kilometers of heavy‑haul operation.
The 202V01201-0460 Mc 13 cylinder liners are not generic cast iron tubes; they are precision‑engineered components specifically developed for SINOTRUK Sitrak’s MC13 engine. These wet‑type liners feature a centrifugally cast structure that provides a uniform, fine‑grained pearlitic matrix with evenly distributed graphite flakes, resulting in exceptional wear resistance and scuff‑free operation. The liner’s bore surface is finished with a plateau honing process that creates a micro‑oil reservoir pattern, ensuring rapid piston ring break‑in and sustained low oil consumption throughout the liner’s service life.
Engine endurance data from MC13 platforms confirms that using the genuine 202V01201-0460 cylinder liners reduces cylinder bore wear by over 60% compared to aftermarket alternatives. The liners’ optimized wall thickness and external cooling jacket design maximize heat transfer to the coolant, maintaining consistent cylinder temperatures and preventing hot spots that can lead to piston scuffing. For fleet managers, this translates into extended overhaul intervals, reduced oil consumption, and lower total cost of ownership.
Centrifugally cast iron with optimized microstructure delivers hardness of 220–260 HB, resisting abrasive wear from combustion residues.
Precision‑controlled wall thickness and external cooling jacket geometry ensure uniform heat dissipation, preventing thermal distortion.
Plateau honed bore surface with Ra 0.4–0.8 μm finish and optimized cross‑hatch angle ensures rapid ring seating and low oil consumption.

The 202V01201-0460 cylinder liners are produced using a centrifugally cast process that ensures a uniform, fine‑grained pearlitic matrix with evenly distributed Type A graphite flakes. This structure provides exceptional wear resistance and scuff‑free operation under high cylinder pressures. After casting, each liner undergoes stress relieving, then rough and finish machining with CNC equipment to achieve bore roundness within 0.005 mm and straightness within 0.01 mm over the entire length. The final plateau honing step uses diamond stones and a computer‑controlled stroke to create the optimized micro‑geometry required for minimal oil consumption and rapid ring seating.
Every liner is 100% inspected for bore geometry, hardness, and surface finish using coordinate measuring machines and optical profilometers. This level of quality control ensures that the genuine 202V01201-0460 liners meet or exceed Sinotruk’s stringent specifications, providing the foundation for long‑term engine reliability.
When installing the genuine 202V01201-0460 cylinder liners, ensure the engine block counterbores are clean and free of corrosion. Measure liner protrusion using a dial gauge; acceptable range is 0.08–0.12 mm above the block deck. Apply a thin film of anti‑seize compound on the liner flanges and use new O‑rings to prevent coolant leaks. Press liners into place using a suitable tool, never hammering directly. After installation, verify that each liner rotates freely by hand.
Regular maintenance should include monitoring oil consumption and coolant levels. Any sudden increase in oil consumption may indicate bore glazing or wear. Using the genuine 202V01201-0460 liners ensures that the replacement components match the original metallurgy and surface finish, preventing premature wear and maintaining engine efficiency. For overhaul, always replace liners as a full set to ensure uniform compression and consistent cylinder performance.
Worn cylinder liners typically exhibit increased oil consumption, blow‑by, and reduced engine power. Visual inspection often reveals vertical scratches or a polished, glazed bore surface. If these signs appear, immediate replacement with the genuine 202V01201-0460 liners is essential. Continued operation with worn liners can lead to piston ring breakage and catastrophic engine damage. Proactive replacement at 800,000–1,000,000 km is recommended for heavy‑haul applications.
Additionally, always inspect the cylinder block for cavitation erosion around the liner seats; any pitting should be repaired or the block replaced. Using the genuine 202V01201-0460 liners with their precise external geometry helps maintain proper coolant flow and prevents hot spots that accelerate erosion.
Every 202V01201-0460 Mc 13 cylinder liner is manufactured in IATF 16949 certified facilities, with 100% dimensional inspection, 100% ultrasonic testing for internal defects, and 100% hardness verification. Each liner undergoes a 200‑hour thermal cycling test to validate structural integrity under simulated operating conditions. The bore surface is measured with laser interferometry to confirm plateau‑honing quality. Counterfeit liners often use lower‑grade iron with inconsistent hardness and inadequate honing, leading to rapid wear and high oil consumption; the genuine 202V01201-0460 guarantees safety, reliability, and full SINOTRUK warranty coverage.
Aftermarket cylinder liners frequently use lower‑grade grey iron with a coarse, uncontrolled microstructure that leads to rapid abrasive wear and scuffing. Many non‑original liners also lack proper plateau honing, resulting in extended ring break‑in times and high initial oil consumption. In contrast, the genuine 202V01201-0460 features a precisely controlled metallurgy and surface finish that ensures immediate sealing and sustained performance.
Additionally, aftermarket liners often have dimensional variations that cause improper liner protrusion, leading to head gasket failure and coolant leaks. The genuine 202V01201-0460 liners are produced to exacting tolerances, guaranteeing correct sealing and thermal transfer. By choosing the original 202V01201-0460 Mc 13 cylinder liners, you eliminate the risk of premature engine failure, minimize oil consumption, and ensure maximum uptime for your fleet.
