Parts for Detroit Diesel 12V71 Turbo – Oil Pump Section

The Detroit Diesel 12V71 Turbo engine is part of the renowned Series 71 family, a line celebrated for its enduring design and exceptional performance across marine, industrial, and transportation applications. The oil pump system for the 12V71 Turbo plays a critical role in maintaining engine longevity, ensuring consistent lubrication across all moving components, and controlling temperature under demanding conditions. This section details all the vital oil system components available through Diesel Pro Power—your trusted global source for Detroit Diesel parts.

Oil Pump Overview for the Detroit Diesel 12V71 Turbo

The 12V71 Turbo engine utilizes a precision-engineered gear-driven oil pump that delivers constant oil pressure to the crankshaft, camshaft, pistons, and turbocharger bearings. These pumps are specifically designed to handle high RPM operation and heavy load cycles typical of marine propulsion, industrial power units, and on-road heavy-duty trucks. The correct oil pump not only ensures sufficient lubrication but also contributes to the cooling and cleaning of critical internal surfaces by circulating filtered oil under pressure.

Diesel Pro Power offers both marine and industrial versions of the rebuilt Detroit Diesel 12V71 oil pump. Each pump is meticulously rebuilt by skilled technicians, tested to OEM specifications, and comes with a refundable core deposit to encourage responsible recycling of components. These pumps are designed for direct replacement—guaranteeing a precise fit and factory-grade reliability.

Rebuilt Oil Pump for Marine Applications

The Detroit Diesel 12V71 Turbo Marine Oil Pump (Rebuilt) is engineered for continuous-duty operation. Marine environments require exceptional oil pressure stability to protect against saltwater corrosion, high humidity, and prolonged operation at constant loads. This pump features durable internal gears and housings designed to withstand extended running hours under high pressure, ensuring even oil distribution throughout the turbocharged engine.

Each rebuilt marine oil pump includes:

• Full pressure and flow testing to verify OEM performance levels.

• Replacement of all wear components, including bushings, gears, and seals.

• Re-machining of surfaces to ensure precise oil clearance.

• Compatibility verification with all 12V71 turbocharged marine engines.

When installed, this pump helps maintain optimal lubrication pressure for the crankshaft, connecting rods, camshaft, and turbo bearings—critical components under constant high load.

Industrial and Truck Oil Pump

The Detroit Diesel 12V71 Industrial Oil Pump (Rebuilt) is designed for engines operating in land-based or mobile heavy-duty applications such as trucks, loaders, power generators, and industrial machinery. These units face a wider range of RPM fluctuations and higher temperature variations than marine setups, so the industrial oil pump version incorporates reinforced housings and modified flow rates suitable for transient engine speeds.

Key features include:

• Reinforced steel gear sets for improved durability under variable loads.

• Calibrated pressure relief valve to maintain optimal system pressure.

• 100% compatibility with all industrial 12V71 turbo engine setups.

• Rebuild process exceeding OEM standards for oil delivery and volume control.

Proper lubrication within industrial and truck applications is essential for maintaining turbocharger integrity and preventing bearing failure, especially under heavy towing or constant high-RPM cycles.

Oil Pump Shims

Oil pump shims are essential components for setting correct oil pump clearance and pressure balance. Diesel Pro Power supplies precise Detroit Diesel Oil Pump Shims in various thicknesses—including .010 and .020-inch options—for the 6V71, 8V71, 12V71, and 16V71 engines. Adjusting shim thickness allows fine-tuning of oil pressure levels, ensuring consistent flow across the entire lubrication system.

Oil Pressure Relief Valve

The Detroit Diesel Oil Relief Valve serves as a safeguard for the lubrication circuit by controlling maximum oil pressure. When pressure exceeds the designed limit, the valve opens to reroute excess oil back to the sump, preventing damage to seals and bearings. For the 12V71 Turbo, Diesel Pro Power offers a heavy-duty valve assembly tested to maintain system stability under high boost and elevated oil flow demands typical of turbocharged operation.

Oil Pan Gaskets and Seals

The oil pan gaskets play an essential role in preventing leaks at the interface between the oil pan and the engine block. For the 12V71 Turbo, Diesel Pro Power offers both small and large gasket variations, allowing users to match their specific configuration—whether a single or double oil pan setup. These gaskets are manufactured from high-grade materials resistant to oil saturation and temperature cycling, ensuring long-term sealing integrity.

Oil Pump and Cooler Gaskets

Every gasket in the oil system contributes to maintaining oil pressure and cleanliness. The catalog includes:

• Oil Pump Inlet Gaskets and Inlet Pipe Gaskets, which seal suction pathways and prevent air from entering the pump system.

• Oil Cooler Gaskets, used between cooler plates and housings to prevent oil and coolant mixing.

• Oil Filter Adaptor Gaskets, ensuring a leak-free seal between filter bases and the block.
  These gaskets are cut from precision composites designed for durability under continuous high-pressure cycles.

Oil Filter Components

The oil filter assembly in the 12V71 Turbo system captures contaminants and maintains clean lubrication. Diesel Pro Power provides:

• Cartridge-type filters, for classic setups.

• Spin-on filters, offering quick installation and replacement.

• Oil Filter Adaptors, allowing conversion from older cartridge designs to modern spin-on filters for improved maintenance efficiency.
  Each filter base and adaptor is machined for a precise fit to Detroit Diesel’s 12V71 configuration, ensuring uninterrupted oil flow and proper filtration.

Oil Cooler Assembly

The oil cooler is another critical component that helps regulate temperature in the engine oil. Turbocharged engines generate significant heat, and maintaining optimal oil temperature is vital for preventing viscosity breakdown. Diesel Pro Power provides various configurations including 12-plate, 24-plate, and 24-plate-with-nipples oil coolers.

These coolers feature:

• Copper and brass construction for maximum thermal conductivity.

• Internal baffles to enhance oil flow distribution.

• Leak-tested housings for marine and industrial reliability.

Complementing these are several gasket sets and seals designed to ensure proper installation. The oil cooler installation kit for double coolers is ideal for large 12V71 turbocharged marine applications where dual cooling units are required for heavy load conditions.

Seals and Manifold Connections

To prevent oil and coolant cross-contamination, Diesel Pro Power supplies a complete range of seals for water manifold-to-oil cooler housings. Available in several diameters, these seals use heat-resistant materials suitable for high-temperature and high-pressure environments. Correct sealing prevents coolant leaks into the oil system, maintaining lubrication quality and preventing internal corrosion.

Dipstick Assemblies and Guides

Accurate oil level measurement is essential for maintaining proper lubrication pressure. Diesel Pro Power offers dipsticksin multiple lengths and configurations for both marine and industrial 12V71 Turbo engines, along with dipstick tubes and guides. These are precision-calibrated to reflect correct oil levels based on engine model and oil pan configuration.

Oil Pressure Switches

The catalog includes a variety of Fuel and Oil Pressure Switches ranging from 5 PSI to 27 PSI make/break thresholds. These switches are used for both warning systems and automatic engine shutdown protection in marine and industrial environments. Proper oil pressure monitoring ensures operators are alerted to any potential lubrication system failure before critical damage occurs.

Mechanical and Electrical Gauges

Complementing the switches, Diesel Pro Power supplies mechanical and electrical oil pressure gauges in 12-volt and 24-volt versions. These instruments provide real-time pressure readings, allowing operators to monitor the health of the lubrication system continuously.
