Known for its distinctive two-stroke design, the 6-71 Turbo model features a turbocharger that enhances airflow efficiency and boosts horsepower output, all while maintaining the same rugged mechanical simplicity that made the naturally aspirated 6-71 a favorite across the globe.

This catalog section focuses on every vital component that supports the lubrication system of the 6-71 Turbo — from the oil pump and coolers to the filters, seals, and gaskets that keep oil circulating cleanly and efficiently. Whether you’re rebuilding a marine propulsion engine, maintaining an auxiliary generator, or restoring a vintage heavy-duty truck, these parts are designed to ensure consistent oil pressure, proper cooling, and optimal performance.

Understanding the 6-71 Turbo Oil System

The oil system in the Detroit Diesel 6-71 Turbo engine serves as the lifeblood of the entire power unit. Beyond simple lubrication, it performs several critical roles — reducing friction, removing heat, cleaning moving components, and ensuring the turbocharger itself is adequately lubricated. The turbocharged configuration places additional demands on oil circulation, as the turbo bearings operate at extremely high RPMs and temperatures.

To meet these challenges, the system uses a precision-engineered oil pump to maintain steady pressure, a network of coolers and filters to control temperature and purity, and a series of gaskets and seals to prevent leaks. The parts listed here form a complete ecosystem — allowing operators to maintain factory-grade oil performance standards across marine, industrial, and vehicular applications.

Detroit Diesel Oil Pumps for the 6-71 Turbo

These units are sold with refundable core deposits, reflecting Diesel Pro Power’s commitment to sustainability and cost efficiency.

Each oil pump plays a crucial role in drawing oil from the pan, pressurizing it, and distributing it through critical pathways — including the crankshaft bearings, camshaft bushings, rocker arms, and turbocharger. A malfunctioning or worn pump can lead to inadequate lubrication, resulting in increased engine wear or even catastrophic failure.

Oil Pump Rebuild Quality and Testing
Rebuilt pumps at Diesel Pro Power are fully disassembled, cleaned, and re-machined where necessary. Wear components like gears, seals, and bushings are replaced with new, high-quality equivalents. The housing is inspected for scoring and flatness, ensuring perfect gear clearance and pressure consistency. Each pump is bench-tested to verify flow rates and pressure retention under load.

Compatibility Across the Series 71 Family
While this section focuses on the 6-71 Turbo, many of these pumps are also compatible with other Series 71 configurations such as the 3-71, 4-71, and naturally aspirated 6-71 engines. The design continuity across the Series 71 family allows for simplified maintenance and part interchangeability — one of the key reasons these engines remain popular worldwide.

Oil Pump Gaskets, Shims, and Repair Kits

Gaskets and Seals
Oil pump gaskets for the 6-71 Turbo ensure leak-free connections between the pump body, cover plates, and adjoining housings. Proper sealing maintains oil pressure throughout the system and prevents contamination. Gaskets must be replaced during every overhaul or oil pump removal to ensure reliable operation.

Pump Shims and Calibration
The oil pump shim (commonly used in the 3-71, 4-71, and 6-71) allows for precise adjustment of pump clearances and pressure regulation. Even a small deviation in oil pressure can affect turbo lubrication and bearing longevity. Maintaining the correct shim thickness helps preserve ideal oil pressure — typically within Detroit Diesel’s specification range for the 6-71 Turbo engines.

Complete Oil Pump Repair Kits
For operators who prefer in-house rebuilds, Diesel Pro Power offers a comprehensive oil pump repair kit designed for the Detroit Diesel 6-71. Each kit includes seals, gaskets, fasteners, and other wear components required to restore the pump to proper working condition. These kits are essential for long-term maintenance programs in fleets and shipboard engine rooms where downtime must be minimized.

Oil Coolers and Cooling Components

6-, 8-, and 13-Plate Oil Coolers
Turbocharged engines produce significantly more heat, particularly in the oil system. The Detroit Diesel 6-71 Turbo relies on an oil cooler to remove excess thermal energy from the circulating oil. Options include 6-plate, 8-plate, and 13-plate coolers — each tailored for different operating environments and duty levels.

The multi-plate construction provides high surface area for efficient heat exchange between oil and coolant. In marine applications, seawater passes through the cooler housing, absorbing heat from the oil. The 13-plate design, often chosen for high-performance or continuous-duty engines, ensures stable oil temperatures even under heavy loads.

Cooler Adaptor Gaskets and O-Rings
Every cooler connection requires precise sealing. Diesel Pro Power supplies all associated gaskets, O-rings, and seals, including those for the cooler tube, cooler adaptor, and block interfaces. These seals prevent oil and coolant from mixing — a critical safeguard, since cross-contamination can rapidly lead to bearing failure or turbo damage.

Marine Application Note
For marine installations of the 6-71 Turbo, maintaining a clean and corrosion-free oil cooler is vital. Saltwater deposits or restricted flow can impair cooling performance. Diesel Pro Power’s marine-grade cooler components and seals are designed with corrosion-resistant materials to extend service life in demanding environments.
