Product Features & Engineering Advantages
Critical Component for Engine Longevity
The oil pump is the heart of the engine lubrication system. It draws oil from the oil pan and forces it under pressure through oil galleries to rotating bearings, sliding pistons, and the camshaft. Consistent oil pressure is essential to prevent premature wear and engine failure in heavy-duty excavator applications.
Precision Trochoid Rotor Design
Features precision-engineered trochoid gear rotors that ensure consistent oil flow and pressure regulation. This advanced design provides smoother operation and more efficient oil delivery compared to traditional gear pumps, reducing operational friction and improving overall engine efficiency.
High-Pressure Performance
Engineered to deliver high-pressure oil to components requiring regular lubrication such as crankshaft and camshaft bearings. Maintains adequate oil pressure even under heavy load conditions common in excavator and construction applications. Ensures proper lubrication during cold starts and high-temperature operation.
Robust Construction
Manufactured from high-strength cast iron housing with hardened steel rotors. Built to withstand extreme combustion pressures and temperatures in demanding construction and mining environments. Corrosion-resistant construction ensures long-lasting performance under extreme engine temperatures and pressures.
Direct Crankshaft Drive
Engineered for direct drive from the crankshaft, ensuring positive and reliable operation whenever the engine is running. This eliminates the risk of auxiliary drive system failure and ensures immediate oil pressure upon startup.
OEM-Compliant Specifications
Manufactured to meet or exceed original Yanmar specifications for the 4TNV94 engine series. Ensures compatibility with Yanmar, John Dee re, and other equipment brands using this engine platform.
Compatible with Various Engine Configurations
Suitable for both naturally aspirated and turbocharged (4TNV94HT) engine variants. Works with common rail and direct injection systems common in Yanmar Tier 4 compliant engines.
Multiple Condition Options Available
Available as brand new aftermarket units or professionally remanufactured pumps. Remanufactured options undergo rigorous cleaning, inspection, and testing to provide a cost-effective alternative without compromising quality.
Quality Assurance
  • 100% Tested - Every oil pump undergoes functional testing to ensure proper pressure and flow characteristics before shipment
  • OEM Standard - Manufactured to meet or exceed original equipment specifications in ISO-certified facilities
  • Warranty - 6-month warranty against manufacturing defects
  • Global Shipping - Fast DHL, FedEx, UPS shipping available from multiple warehouses
  • Expert Support - Need help identifying your part? Send us your engine code or old part number
Installation Note
The oil pump is typically located inside the timing gear case or oil pan. When installing a new oil pump on a Yanmar 4TNV94 engine, it is critical to ensure proper priming before startup to avoid dry running damage.
Always inspect the oil pickup tube O-ring and screen for debris during installation. Professional installation is recommended due to the precision required for proper alignment and sealing. Regular oil changes with the correct viscosity oil (typically 10W-30 or 15W-40 API CI-4 or higher) will extend the life of both the oil pump and the engine.
Warning: Never operate the engine without verifying proper oil pressure after pump replacement. Low oil pressure can cause immediate and severe engine damage.
