Its crankshaft-driven rotary design, five mounting holes, and precision-ground end plates support efficient operation under real engine conditions. The pump is individually tested for pressure and flow, and the M146 part number is commonly referenced in stock replacement service for Toyota 4Runner, Toyota Pickup, and Toyota Celica applications.\u003c\/p\u003e\u003cp\u003eThis part cross-references DNJ OP900 and EM-146 for the same application. The M146 is a practical choice when replacing a worn oil pump in a Toyota 4Runner, Toyota Pickup, or Toyota Celica and restoring stable lubrication performance.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLow oil pressure caused by pump wear\u003c\/li\u003e\n\u003cli\u003eInconsistent oil circulation during engine operation\u003c\/li\u003e\n\u003cli\u003eLoss of lubrication from worn internal pump components\u003c\/li\u003e\n\u003cli\u003eService replacement for stock engine oil pump maintenance\u003c\/li\u003e\n\u003cli\u003eRestoring proper pressure and flow in the lubrication system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify engine application and pump configuration before installation. Inspect the mating surfaces, replace the gasket or seal as needed, and confirm the drive engagement and mounting alignment during assembly. The M146 uses a crankshaft drive type and standard pressure\/volume calibration, so matching the original setup is important for correct operation.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eMelling manufactures this oil pump to production standards and tests each unit for pressure and flow under conditions that simulate engine operation.
