The J3300-1002064A cylinder liner is produced using the centrifugal casting process, which ensures a uniform microstructure and eliminates porosity. The material is a high‑strength alloyed cast iron (GGG‑40 equivalent) with precisely controlled graphite morphology, providing excellent wear resistance and thermal conductivity. The inner bore is plateau‑honed to a mirror‑like finish with a defined cross‑hatch pattern that retains oil and promotes rapid ring seating. The liner’s outer diameter is precision‑ground to ensure a perfect interference fit in the engine block, preventing cavitation and movement under load.
Each J3300-1002064A liner undergoes 100% inspection, including dimensional checks for bore diameter, roundness, and surface finish. A non‑destructive eddy current test is performed to verify material integrity and detect any subsurface defects. The liner also meets strict hardness specifications (230‑280 HB) to resist abrasive wear from piston rings. This rigorous quality control guarantees that the liner will provide consistent compression, low oil consumption, and extended engine life under the most demanding conditions.

The J3300-1002064A cylinder liner is a direct OEM replacement used in Howo engines such as the WD615, MC11, MC13, and D10 series. It is installed in the engine block as a dry liner, where it forms the cylinder wall against which the piston rings seal. The liner’s precise dimensions and superior surface finish ensure minimal friction and oil consumption while maintaining high compression for efficient combustion.
In heavy‑duty applications, the cylinder liner is subjected to extreme thermal and mechanical stresses. A worn or damaged liner can lead to blow‑by, oil consumption, power loss, and ultimately engine failure. The genuine J3300-1002064A liner restores original engine performance, ensuring that your Howo truck continues to operate reliably in mining, construction, and long‑haul environments. It is also used in remanufactured engines and as a standard replacement part during major overhauls.
When replacing cylinder liners, always use new piston rings and seals. Ensure the block bore is clean and within specifications. Follow the correct liner protrusion and use a liner puller tool to avoid damage.
Correct installation of the J3300-1002064A cylinder liner is essential to ensure proper sealing and long engine life. Follow these steps:
Thoroughly clean the engine block cylinder bore. Remove any old sealant or debris. Measure the block bore and the liner outer diameter to verify correct interference fit.
Apply a thin layer of liner sealant (if specified) to the outer surface. Using a liner press, slowly and evenly press the liner into the bore until it reaches the correct protrusion above the block deck. Never hammer the liner.
After installation, check liner protrusion with a dial gauge to ensure it is within 0.03‑0.10 mm. Re‑check the bore diameter for distortion. Install new piston rings and piston.
Worn cylinder liners can cause a range of engine performance issues. Common signs that replacement is needed include:
If any of these symptoms are observed during engine overhaul, immediate replacement with genuine J3300-1002064A liners is recommended. Continuing to operate with worn liners can lead to piston ring failure and catastrophic engine damage.
The alloyed cast iron and precise heat treatment provide excellent resistance to abrasive and adhesive wear, extending engine life.
The plateau‑honed surface retains oil for optimal ring lubrication, minimizing oil passing into the combustion chamber.
Precision‑ground outer diameter and exact length ensure correct interference fit and protrusion, guaranteeing a perfect seal every time.
To maximize the service life of your J3300-1002064A cylinder liners, follow these best practices:
By adhering to these guidelines, you ensure that the J3300-1002064A liners perform optimally throughout their intended service interval.
Aftermarket cylinder liners are often made from inferior cast iron with inconsistent hardness and poor surface finish. They may have incorrect dimensions, leading to poor fit, hot spots, and premature failure. The genuine J3300-1002064A is manufactured to the exact specifications of the original equipment, using premium alloyed iron and state‑of‑the‑art centrifugal casting. Each liner is inspected for hardness, microstructure, and dimensional accuracy, guaranteeing that it will perform exactly as the original part.
By choosing authentic SINOTRUK HOWO parts, you protect your investment and ensure your truck maintains its power, efficiency, and resale value. The Sinotruk howo parts catalog includes a full range of engine and chassis components engineered for maximum durability. For fleet managers and owner‑operators who demand the best, the genuine J3300-1002064A is the only responsible choice.
The J3300-1002064A cylinder liner is used across a wide range of Howo models: T7H, A7, and classic Howo‑7 series equipped with WD615, MC11, MC13, and D10 engines. Always verify the liner height and bore diameter using the service manual; different engine variants may have slight dimensional differences.
Each J3300-1002064A is individually wrapped in protective oiled paper to prevent rust. The packaging is clearly labelled with the OEM number and batch code. For bulk orders, liners are shipped in sealed cartons with foam separators to avoid transit damage.
Production of the J3300-1002064A takes place in IATF 16949 certified facilities, using precision centrifugal casting and CNC machining with in‑process gauging. Statistical process control ensures that dimensional variations are kept to a minimum, far exceeding the requirements of the original design. Every batch is accompanied by a material certificate and hardness test report, guaranteeing that the liners delivered are identical to those fitted on new Howo trucks at the factory.
