OEM Cylinder Liner 1002916798 designed exclusively for the Shacman X5000 heavy‑duty diesel engine. This precision‑ground 1002916798 liner forms the perfect running surface for piston rings, ensuring optimal compression and oil control across hundreds of thousands of kilometers.
Manufactured from high‑grade centrifugal cast iron, the Cylinder Liner 1002916798 offers exceptional wear resistance and heat dissipation. Its honed inner surface retains oil for lubrication while minimizing blow‑by and oil consumption under extreme turbocharged pressures.
Replacing worn liners with genuine 1002916798 units restores engine compression to factory specifications, improving fuel efficiency and reducing exhaust emissions. Each liner is inspected to meet Shacman’s stringent roundness and surface finish requirements.

The 1002916798 cylinder liner is the direct interface between the piston rings and the engine block. It must withstand combustion temperatures exceeding 800°C while maintaining a precise bore geometry that supports compression ratios critical for diesel ignition.
When liners wear beyond their service limit, piston ring sealing degrades rapidly. This leads to crankcase pressurization, increased oil consumption, and reduced power output. Installing a fresh set of genuine Cylinder Liner 1002916798 components reverses these symptoms.
The 1002916798 liner is produced using a centrifugal casting method that forces impurities to the outer surface, which is subsequently machined away. This results in a dense, homogeneous inner bore structure free from porosity.
The phosphorus alloy addition creates a network of hard iron phosphide particles throughout the matrix. These particles provide excellent scuff resistance during cold starts when oil pressure has not yet fully developed in the engine.
The inner surface of the Cylinder Liner 1002916798 undergoes a plateau honing process. This creates a series of deep valleys for oil retention and flat peaks that support the piston rings. The result is a surface that seats rings quickly while maintaining long‑term wear resistance.
Proper oil retention in these honing grooves is essential for lubricating the top piston ring, which operates under the most severe thermal and mechanical stress. Insufficient lubrication leads to micro‑welding and catastrophic ring failure.
Every 1002916798 liner is measured for roundness and cylindricity using air gauging equipment. The tolerance for bore distortion is held to within 0.01 mm, ensuring that piston ring tension remains uniform around the entire circumference.
The outer diameter that fits into the engine block is ground to a precise interference specification. This guarantees correct liner protrusion above the block deck, which is critical for achieving a reliable cylinder head gasket seal.
Before installing the 1002916798 liner, thoroughly clean the block counterbores and inspect for corrosion. The new O‑ring seals must be lubricated with clean engine oil and carefully positioned to avoid twisting during insertion.
Liner protrusion should be checked at multiple points around the circumference using a dial indicator. The specified protrusion for the Cylinder Liner 1002916798 ensures that the fire ring of the head gasket receives adequate clamping force.
The 1002916798 liner is specifically designed for the Shacman X5000 engine. Fleet operators benefit from a single part number across their vehicles, simplifying inventory management and ensuring that the correct component is always available.
Mixing genuine 1002916798 liners with aftermarket alternatives can create an imbalance in cylinder compression and thermal expansion rates. For consistent engine performance, always replace all six liners as a matched set.
The market contains many imitation liners that fail prematurely. We supply only the authentic Shacman X5000 Cylinder Liner 1002916798 with complete manufacturer documentation and anti‑counterfeit verification.
Each liner is protected with a rust‑preventive coating and packed in a custom foam insert to prevent handling damage during shipping. Our logistics partners are experienced in handling precision engine components.
When ordering, always specify the full part number 1002916798 to receive the correct wet‑type liner for the X5000 application. Our technical team can assist with engine serial number verification to eliminate any possibility of error.
