DJ Rock OP602 Engine Oil Pump

Engine Oil Pump for Nissan Applications

The DJ Rock OP602 engine oil pump is a premium gear-style pump built to maintain steady oil pressure throughout the engine. It is a direct-fit lubrication component for select Nissan models, including the D21, Pathfinder, 720, Maxima, 200SX, 280ZX, 510, and 810.

With a cast iron housing, drive shaft operation, and standard pressure/standard volume output, this pump is built for consistent oil circulation in demanding engine conditions.

Key Features

• Premium-grade engine oil pump for lubrication system service
• Cast iron housing for strength and resistance to heat-related distortion
• Gear-type oil pump design for steady oil delivery
• Drive shaft driven for direct mechanical operation
• Standard pressure and standard volume output
• Gasket or seal included for installation support
• 4 mounting holes for secure fitment

Detailed Description

The DJ Rock OP602 oil pump is engineered to circulate engine oil under pressure so rotating and sliding components receive consistent lubrication. Its gear-type design helps maintain oil flow across a wide range of operating conditions, while the pressure relief function regulates system pressure during cold starts and higher engine speeds. The cast iron housing adds durability in high-temperature environments, and the drive shaft configuration matches the mechanical layout used in the listed Nissan engines. This part cross-references Sealed Power 224-41901 and Spectra Premium M111 for the same application. For Nissan D21, Pathfinder, 720, Maxima, 200SX, 280ZX, 510, and 810 service, OP602 is a practical replacement when restoring oil pressure and lubrication performance.

What It Helps Address

• Low oil pressure readings
• Reduced oil circulation through the engine
• Engine noise related to lubrication loss
• Wear from inconsistent oil delivery
• Pressure fluctuation during cold starts or higher RPM operation

Installation Notes and Tips

Verify engine application and pump drive style before installation. Inspect the mating surfaces, oil passages, and related seals during service. Prime the pump and confirm proper oil pressure after startup. For Nissan D21, Pathfinder, and 280ZX applications, follow the factory service procedure for timing and lubrication system checks.

Quality Assurance

DJ Rock OP602 is built to meet or exceed OEM quality standards using durable materials and precision internal components. The pump includes a gasket or seal and is designed for reliable lubrication system service in the listed Nissan applications.
