High Performance Truck Parts Fuel Filter HA11383

1. Core Function & Design Philosophy

2. Premium Material & Precision Manufacturing

• Filter Media: Adopts high-density multi-layer composite filter paper with high porosity and excellent dirt-holding capacity. It efficiently captures metal shavings, carbon deposits, dust, and sludge as small as 5–10 microns, preventing abrasive wear on engine cylinders, crankshafts, bearings, and camshafts.
• Housing & Structure: Constructed from thick, high-strength steel plate with anti-rust and anti-corrosion coating. The sealed, pressure-resistant casing withstands system pressure up to 1.0 MPa, avoiding oil leaks or deformation under heavy loads. The internal heavy-duty spring-loaded bypass valve ensures uninterrupted oil supply during cold starts or when the filter is clogged, protecting the engine from oil starvation.
• Sealing System: Equipped with a high-temperature-resistant rubber gasket (nitrile rubber) that maintains elasticity and sealing performance at temperatures from -30°C to 120°C, preventing oil leakage at the installation interface.

3. Key Performance Advantages

1. High Filtration Efficiency: Achieves ≥98% filtration accuracy for solid particles, effectively extending engine service life and reducing maintenance costs.
2. Excellent Compatibility: Fully compatible with API CJ-4/CI-4/CH-4 grade diesel engine oils, suitable for both conventional and high-pressure common rail fuel systems.
3. Long Service Interval: The robust filter media and large dirt-holding capacity support a service life of 5,000–10,000 kilometers (depending on operating conditions), reducing replacement frequency and downtime.
4. Harsh Environment Adaptability: Performs reliably in extreme environments such as high temperature, high humidity, dusty construction sites, and muddy roads, ensuring stable engine lubrication in mining, logistics, and engineering machinery scenarios.

4. Installation & Maintenance Notes

• Direct Fit: Standardized size and interface enable tool-free, quick installation (screw-on design), matching OE part numbers L1007-061 and JX0810.
• Genuine Quality Guarantee: As an original Yunnei Power accessory, it undergoes 100% quality inspection, including pressure testing, filtration efficiency testing, and durability cycling, to meet OEM quality standards.
• Replacement Reminder: For optimal engine protection, replace the HA11383 oil filter during every oil change, especially for vehicles operating in heavy-load or dusty conditions.

5. Application Scenarios

• Light-duty trucks (Yunnei D25/D30 engine models)
• Forklifts and material handling equipment (490 series engines)
• Small construction machinery (excavators, loaders)
• Commercial vehicles and agricultural machinery
