160102130004A001 Cylinder Liner – Heavy-Duty SANY Diesel Engine Component

Precision cylinder bore for SANY high-output diesel engines. The 160102130004A001 Cylinder Liner is a premium OEM-grade sleeve engineered for exceptional wear resistance, optimal heat transfer, and reliable piston guidance in SANY heavy-duty diesel engines. This centrifugally cast liner features a precision-honed inner bore and a carefully engineered outer profile ensuring perfect interference fit within the engine block. Trusted worldwide, SANY parts deliver consistent accuracy and material integrity. With OEM number 160102130004A001, this Cylinder Liner dramatically reduces oil consumption, maintains compression sealing, and extends overhaul intervals in SANY excavators, loaders, and heavy-haul equipment.

The 160102130004A001 Cylinder Liner is a wet-type sleeve forming the combustion chamber bore within SANY diesel engines. It is the critical sliding surface for piston rings, directly affecting oil consumption, blow-by control, and overall efficiency. Six liners are required per complete SANY six-cylinder engine build.

The liner is manufactured using the centrifugal casting process. Molten special-alloy cast iron is poured into a rapidly rotating mold; centrifugal forces distribute the metal evenly, creating a homogeneous microstructure with exceptional density and consistent grain orientation. This eliminates porosity and aligns graphite flakes circumferentially.

As a wet-type liner, the outer surface of the 160102130004A001 is in direct contact with engine coolant circulating through the water jacket. This provides superior heat transfer away from the combustion zone, enabling higher specific power outputs and better thermal stability under sustained loads.

The wet design also allows each liner to be replaced individually during engine overhaul without requiring complete block machining. This significantly reduces rebuild costs and downtime for SANY equipment operators.

The 160102130004A001 features a stepped outer profile with precisely machined sealing grooves that accept O-rings (Part No. 160102120008A001) at both upper and lower sealing lands. These O-rings prevent coolant migration into the crankcase and stop combustion gas from entering the cooling system.

The inner bore is finished using plateau honing technology—a two-stage process that removes surface peaks and micro-finishes the final surface. This produces an optimal bearing surface for ring seating and oil retention. The crosshatch angle is controlled between 35 and 45 degrees.

The cast iron alloy includes carbon, silicon, manganese, chromium, and molybdenum to produce a fine pearlitic matrix with Type A graphite flake distribution. Chromium creates hard carbide phases that resist abrasive wear while maintaining machinability.

The liner is installed using interference fit: the engine block is heated and the liner chilled. As components return to ambient temperature, the block contracts around the liner, creating a tight metal-to-metal fit that prevents movement and enhances heat transfer.

After installation, liners are finish-honed in place on a specialized boring station, ensuring all six bores are perfectly aligned and round within 0.005 mm. This provides consistent compression and minimal blow-by throughout the service life of the engine.

The 160102130004A001 Cylinder Liner is a direct OE replacement for many SANY diesel engines. Verified compatible machinery includes SY215C, SY225C-9, SY305C, SY335H-10, SY485H excavators; SW305, SW405K, SW955K wheel loaders; SYZ320C, SYZ436C dump trucks; STC250E, STC800T5 truck cranes; and SRT45C, SRT95C mining trucks.

It also fits SANY engine families including Deutz TCD 6.1L, 9.0L, 13.0L, and selected ISUZU 6HK1, 6BG1 engines equipped with SANY cylinder bore specification. During overhaul, all six liners should be replaced as a set to maintain consistent bore geometry and ring seal across all cylinders.

Fastening uses Hexagon Flange Bolts (Part No. 1001675556), 24 bolts per engine block assembly. Always cross-reference OEM number 160102130004A001 with the engine serial number to ensure correct bore diameter and liner protrusion specifications.

• Block prep: Clean the liner bore thoroughly. Remove old O-ring residue and deposits. Machine deck flat if required.
• Temperature differential: Heat block to 80–100°C, chill liner at -18°C for one hour. Slide liner in without hammering.
• Liner protrusion: After thermal stabilization, protrusion must be 0.10–0.15 mm for correct head gasket sealing.
• O-rings: Ensure O-rings (160102120008A001) are correctly seated. Never install with rolled or twisted rings.
• Final honing: Finish-hone bores with torque plate installed. Aim for RA 0.25–0.45 µm, cross-hatch 35–45°.
• Wear monitoring: Measure bores at major overhauls. Replace when wear exceeds 0.15 mm to avoid piston slap and blow-by.

After honing, thoroughly clean each bore with soapy water and hot water until a white rag remains clean. Record bore measurements (taper ≤0.02 mm, out-of-round ≤0.01 mm). For severe-duty applications, inspect every 4,000–5,000 hours.

The 160102130004A001 has passed 5,000 rapid thermal cycles from -40°C to 450°C at the combustion face while the coolant side cycled -40°C to 135°C. No cracking, distortion, or loss of interference fit occurred.

High-cycle fatigue testing reached 100 million compression cycles at 250 bar peak pressure. Post-test microstructure remained fine pearlitic with Type A graphite; hardness stayed within 5% of initial value. Wear resistance is exceptional.

Field testing in mining and construction recorded average liner service life exceeding 15,000 operating hours without exceeding maximum wear dimensions. Oil consumption was below 0.5% of fuel mass throughout service.

Corrosion testing per ASTM G31 (3,000 hours in coolant at 100°C) and ASTM B117 (500 hours salt spray) showed weight loss <0.10 mg/cm²/h. O-ring grooves maintained dimensional integrity after 2,000 coolant cycles.

Each liner is 100% inspected via CMM for dimensions, plus metallurgical and NDT checks (eddy current). Only components passing all gates are released as genuine SANY parts.

Counterfeit liners use inferior cast iron grades, inadequate chromium content, and poor graphite distribution. They cause rapid ring scuffing, high oil consumption, and excessive blow‑by. Some crack under combustion pressure, leading to catastrophic engine failure.

The OEM 160102130004A001 is manufactured under strict SANY quality assurance with 100% dimensional verification and statistical process control. Each batch is analyzed for chemical composition, microstructure, hardness, and tensile strength.

Plateau honing is performed on sequence‑controlled machines with in‑process gauging. This reduces break‑in wear by up to 40% compared to single‑stage honing used on generic liners.

Traceability allows SANY’s global dealer network to verify origin and quality. Genuine parts are backed by comprehensive warranty; using non‑OEM components may void engine warranty claims.

Protect your investment with genuine SANY liners. The 160102130004A001 ensures correct fitment, prevents blow‑by, reduces oil contamination, and delivers the lowest total cost of ownership.
