Yuchai engine spare parts Filter assembly K2100-1105350 K2000-1105300

Both filter assemblies deliver exceptional purification performance with gradient filter media, though optimized for their respective engine loads. K2100-1105350 uses a 3-layer composite media (glass fiber + polyester) with 10μm absolute filtration accuracy, capturing 99.6% of particles (metal shavings, carbon deposits) to protect YC6K’s large-bearing crankshaft. K2000-1105300 adopts 15μm media, targeting 99.2% particle retention for YC4E’s compact components. K2100’s 180g dirt-holding capacity (vs. K2000’s 120g) extends service intervals to 25,000km for heavy-duty use, while K2000 suits 15,000km intervals for light-duty. Both maintain pressure drop ≤0.15MPa at rated flow, ensuring stable oil supply and reducing engine wear by 35% compared to aftermarket filters

Engineered for Yuchai engines’ operating conditions, both assemblies feature durable structures with model-adapted enhancements. K2100-1105350 uses a 2.0mm-thick cold-rolled steel housing (Q235) to resist 1.2MPa oil pressure (common in heavy-duty cycles), while K2000-1105300 adopts 1.5mm steel for 0.8MPa medium-duty pressure. Both integrate a galvanized steel inner skeleton (1.0mm) to prevent media collapse under flow surges. The sealing gasket uses nitrile rubber (shore hardness 70±5) with a double-lip design, ensuring no leakage even under 500,000 vibration cycles (5-2000Hz, ISO 16750-3). K2100 adds a pressure relief valve (opening at 0.2MPa) to avoid oil starvation during cold starts, a critical feature for high-power engines

Both filter assemblies exhibit exceptional resistance to engine oil and temperature fluctuations, with tailored performance for application scenarios. K2100-1105350’s media withstands 150℃ continuous temperature (peak 180℃) for YC6K’s high-load heat generation, while K2000-1105300 handles 130℃ (peak 150℃) for YC4E’s moderate operating temp. Both are compatible with mineral oil, synthetic oil, and biodiesel blends, with media swelling ≤2% after 72-hour oil immersion. The steel housing’s electrophoretic coating (80μm thickness) resists corrosion, passing 800-hour salt spray testing (ASTM B117) for K2100 (heavy-duty outdoor use) and 600-hour for K2000 (urban operation). This ensures 1-year/100,000km service life for both, matching engine maintenance cycles

Optimized for fleet maintenance efficiency, both assemblies feature user-friendly designs with model-specific conveniences. K2100-1105350’s hexagonal housing (80mm across flats) allows wrench-free installation, while K2000-1105300 uses a knurled outer ring for hand-tightening—both completing replacement in 10 minutes. Both come pre-assembled with gaskets, eliminating separate parts sourcing. K2100 adds a pressure differential indicator (activating at 0.3MPa) to signal replacement, critical for heavy-duty operators. K2000’s compact size (Φ100×220mm) fits narrow engine bays of light trucks. Clear part number engraving and “IN/OUT” markings prevent misinstallation. A single technician can service 10+ units daily, reducing labor costs and ensuring engine protection
