Parts for Detroit Diesel 6V71 Turbo – Oil Pump Section

The Detroit Diesel 6V71 Turbo engine is part of the legendary two-stroke Series 71 family — a line that defined reliability and endurance across marine, industrial, and heavy-duty applications. Its lubrication system, anchored by a precision oil pump, is vital to maintaining steady oil pressure, preventing wear, and ensuring the turbocharger and rotating assemblies function under ideal conditions.

This section of Diesel Pro Power’s catalog is dedicated to every key component of the 6V71 Turbo’s oil system — from the main oil pump to gaskets, seals, coolers, regulators, and filter assemblies. Every part listed is specifically selected for its compatibility with Detroit Diesel’s two-stroke V-series engines, guaranteeing exact fit and superior reliability.

Understanding the 6V71 Turbo Lubrication System

The lubrication system in the 6V71 Turbo engine operates under constant pressure, circulating oil through the block, crankshaft, bearings, and turbocharger to maintain stable performance even under extreme loads. Unlike naturally aspirated versions, the turbocharged 6V71 operates under increased thermal and mechanical stress, requiring impeccable oil circulation and pressure regulation.

Key functions of this system include:

• Lubrication of all moving parts: including pistons, connecting rods, and camshafts.

• Heat dissipation: the oil acts as a secondary cooling agent.

• Protection from contamination: through the oil filter system, which removes carbon and metal particles.

• Turbocharger support: ensuring steady oil supply to high-speed bearings for optimal boost performance.

The following components form the backbone of the oil system — each available new or rebuilt at Diesel Pro Power.

Oil Pumps for Detroit Diesel 6V71 Turbo

Right-Hand and Left-Hand Rebuilt Oil Pumps

The oil pump is the most critical element of the lubrication system. Diesel Pro Power offers both right-hand and left-hand rebuilt oil pumps compatible with the 6V71 Turbo engine. Each unit is carefully rebuilt and tested for flow rate, pressure retention, and internal clearances to meet OEM standards.

• Right-Hand Rotation Pump: Designed for engines with specific gear train configurations, ensuring correct directional oil flow.

• Left-Hand Rotation Pump: Equally vital for setups requiring counter-rotation, particularly in twin marine configurations.

Every rebuilt pump is sold with a refundable core deposit, promoting environmental sustainability through remanufacturing.

Scavenging-Type Oil Pump

For more demanding turbocharged configurations, the scavenging-type oil pump plays a pivotal role. This advanced unit efficiently recirculates oil from the crankcase, ensuring no residual oil remains that could cause foaming or lubrication delays. Built for high-performance 6V71 Turbo and multi-bank configurations, this pump is favored in marine and power generation setups where reliability is paramount.

Oil Pump Gaskets and Shims

Even the best oil pump depends on precision sealing and clearance. Diesel Pro Power offers an extensive selection of oil pump gaskets, shims, and sealing components that ensure optimal alignment and leak prevention.

• Oil Pump Gaskets: These are engineered to resist heat and oil degradation, ensuring a perfect seal between pump and housing.

• Oil Pump Shims: Available in multiple thicknesses (.005, .010, .020), these are used to adjust oil pressure output or gear clearance, fine-tuning pump performance.

Precision shims are especially critical during rebuilds or when replacing pumps, as even minor variations in clearance can affect overall oil pressure.

Oil Pressure Regulation Components

Maintaining the correct oil pressure in the 6V71 Turbo is essential for consistent lubrication and long-term durability. Diesel Pro Power provides all necessary components for pressure regulation and relief systems, including:

• Oil Pressure Regulator Valve: Controls maximum system pressure and prevents over-pressurization.

• Oil Pressure Relief Valve: Ensures rapid pressure release during cold starts or high-load conditions.

• Regulator Springs: Calibrated to factory specifications for correct response times and steady oil flow.

Together, these components protect the engine’s internal parts from damage caused by pressure fluctuations and maintain smooth operation under all load conditions.

Oil Coolers for the 6V71 Turbo

Turbocharged engines generate significantly more heat than naturally aspirated models, making the oil cooler an indispensable component. Diesel Pro Power offers Detroit Diesel oil coolers in various configurations — 13, 16, 18, and 24-plate models — each engineered for efficient heat exchange.

• 13-Plate and 16-Plate Coolers: Ideal for light to medium-duty applications.

• 18-Plate and 24-Plate Coolers: Suitable for heavy marine or industrial use, providing superior cooling capacity.

• Coolers with Nipples: Include integrated fittings for fast installation and secure oil line connections.

Each cooler is built to resist corrosion, handle high oil pressures, and maintain consistent viscosity control across extreme temperature ranges.

Oil Cooler Gaskets and Adapter Seals

Diesel Pro Power provides every sealing element required for oil cooler installation and maintenance. These include:

• Oil Cooler Gaskets and Housing Gaskets: Precision-cut for exact fitment on the 6V71 Turbo’s cooler housing, preventing leaks and cross-contamination.

• Oil Cooler Adapter Gaskets: Seal between the cooler base and adapter, ensuring reliable flow between engine block and cooling stack.

• Oil Cooler Cover Gaskets: Designed for easy replacement during overhauls without distorting under clamping pressure.

• Water Inlet Seals and Gaskets: Maintain watertight connections between cooler housing and manifold.

Each gasket uses oil-resistant composite material capable of withstanding high heat and continuous oil exposure — an essential detail for long-lasting maintenance.

Oil Filtration Components

Proper oil filtration ensures longevity and stable performance for the 6V71 Turbo engine. Diesel Pro Power offers complete filter system components compatible with both original cartridge-type and upgraded spin-on filter assemblies.

• Cartridge-Type Filters: Traditional configuration designed for precise filtration and cost-effective maintenance.

• Spin-On Filter Adaptor Kits: Allow conversion from cartridge to modern spin-on filters, simplifying replacements and reducing service time.

• Oil Filter Bases and Gaskets: Machined to exact OEM tolerances, ensuring perfect fitment and oil flow consistency.

Supporting accessories include oil filter wrenches, adaptor gaskets, and copper sealing washers, all designed to ensure leak-free service.

Additional Lubrication System Components

A complete oil system is more than just pumps and filters. Diesel Pro Power’s catalog also includes:

• Oil Pans and Gaskets: Sealing solutions for the 6V71 and 6V92 configurations, ensuring a clean interface between block and sump.

• Dipsticks and Dipstick Tubes: Precisely calibrated for accurate oil level readings. Available in multiple lengths for varied engine setups.

• Oil Filler Caps and Guides: Designed to prevent contamination during oil refills.

• Pressure Switches (5 to 27 PSI): Compatible with both fuel and oil circuits, ideal for engine monitoring systems.

Each item supports proper oil management and complements the 6V71 Turbo’s lubrication network for consistent, dependable operation.

Cooling & Sealing Interfaces

Since oil and coolant circuits intersect in certain components, Diesel Pro Power also supplies water seals and manifold gaskets connecting oil coolers to the engine’s cooling system.

These parts ensure:

• Zero fluid cross-contamination

• Proper alignment during reassembly

• Prevention of cavitation and leaks under pressure

They’re crucial in marine installations where high thermal stress and vibration can otherwise lead to seal failure.

Finishing and Maintenance Accessories

Completing a rebuild or servicing the 6V71 Turbo engine often involves small but essential components such as:

• Detroit Diesel Green Paint: Perfect for restoring the iconic factory finish after overhaul or component replacement.

• Mechanical and Electric Gauges: Ideal for monitoring oil pressure, temperature, and performance metrics in real time.

These accessories not only ensure mechanical health but also preserve the authentic look and professional appearance of Detroit Diesel engines in marine or industrial installations.
