Product Description
- Part Number: 6218-52-1013 (Alternative: 6218521013)
- Type: Gear-driven oil pump (with drive gear)
- Material: High-strength cast iron housing + precision gear assembly + wear-resistant bearings
- Structure: Integrated drive gear, directly driven by engine camshaft/crankshaft, with pressure relief valve and mounting flange
- Function: Supplies high-pressure oil to the engine lubrication system, ensuring lubrication and cooling of all moving parts
- Pressure Oil Supply: Generates pressure through gear meshing to deliver oil to key moving parts (crankshaft, connecting rod, camshaft, piston, etc.), forming an oil film to reduce metal wear.
- Cooling & Cleaning: Circulating oil carries away frictional heat and metal debris, assisting in engine cooling and cleaning the oil circuit to extend component life.
- Pressure Regulation: Built-in pressure relief valve precisely controls oil pressure, preventing seal damage from excessive pressure or insufficient lubrication from low pressure.
- Durability & Reliability: Precision-machined gears and high-strength housing resist impact and wear, adapting to the harsh conditions of high-load, long-hour construction machinery operation.
- OEM Compatibility: Manufactured to original equipment standards, with perfectly matched drive gear module, mounting holes, and interface dimensions, enabling direct replacement of the original 6218-52-1013 oil pump with easy installation.
Suitable for maintenance and replacement of the lubrication system in heavy construction machinery engines (e.g., Komatsu). It is a core component to ensure stable engine operation and prevent bearing and crankshaft damage.
