DJ Rock OP607 Engine Oil Pump

Engine Oil Pump for Nissan Applications

The DJ Rock OP607 engine oil pump is a premium gear-style replacement built to maintain steady oil pressure throughout the engine. It is a direct-fit lubrication component for select Nissan Frontier, Xterra, Pickup, D21, and 240SX applications, with a cast iron housing and standard-volume, standard-pressure operation.

For rebuilds and oiling system service, this pump helps restore proper circulation in engines that rely on consistent pressure at rotating and sliding surfaces. The OP607 is a practical choice when replacing a worn oil pump on Nissan Frontier and Nissan Xterra models, as well as earlier Nissan Pickup, D21, and 240SX vehicles.

Key Features

• Premium-grade engine oil pump
• Gear-type oil pump design with drive shaft operation
• Cast iron housing for strength and dimensional stability
• Standard pressure and standard volume output
• Gasket or seal included for installation
• Four mounting holes for OE-style fitment

Detailed Product Overview

The DJ Rock OP607 is engineered to circulate engine oil under pressure so critical internal parts receive lubrication during cold starts, normal driving, and higher-load operation. Its gear pump design uses hardened internal components and a pressure relief system to regulate oil pressure as operating conditions change. The cast iron housing adds durability in high-temperature engine environments, while the included gasket or seal supports a cleaner service replacement.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It is a fitment-based replacement for 1998-2004 Nissan Frontier, 2000-2004 Nissan Xterra, 1995-1997 Nissan Pickup, 1990-1994 Nissan D21, and 1989-1990 Nissan 240SX applications. Part number OP607 is also useful when searching for an OE-style Nissan oil pump replacement by application.

What This Oil Pump Helps Address

• Low oil pressure caused by a worn pump
• Inconsistent oil circulation in the engine
• Excessive internal friction from poor lubrication
• Oil pressure fluctuation during cold starts
• Noise or wear related to oiling system degradation

Installation Notes and Tips

Before installation, verify the engine application and compare the mounting pattern, drive type, and pump style to the original unit. Clean the mating surfaces thoroughly and inspect the oil pickup, oil pan, and related lubrication components for contamination or wear. Prime the oiling system and confirm proper pressure after startup to ensure the replacement pump is operating correctly.

Quality Assurance

DJ Rock OP607 is manufactured to meet or exceed OEM quality standards, with materials and construction selected for durability and consistent oil delivery. The pump is built for dependable service in Nissan Frontier, Xterra, Pickup, D21, and 240SX engine applications.
