Detroit Diesel 16V71 Non-Turbo – Engine Overhaul Kit Catalog

The Detroit Diesel 16V71 is one of the most iconic engines in the two-stroke Detroit Diesel Series 71 family. Known for its V16 configuration, naturally aspirated design, and reliability in continuous-duty operations, the 16V71 powered tugboats, offshore supply vessels, heavy industrial machinery, and power generation applications worldwide. When these engines require a full rebuild, a properly assembled overhaul kit is the foundation for restoring performance and extending service life.

Diesel Pro Power offers complete inframe and overhaul kits for the Detroit Diesel 16V71 Non-Turbo engine, backed by more than 40,000 satisfied customers worldwide. Below, you’ll find a detailed guide to the kits, components, and supporting parts that ensure your rebuild project is a success.

Complete Inframe & Overhaul Kits for Detroit Diesel 16V71

One-Piece Piston Overhaul Kit

Designed for natural (non-turbo) Detroit Diesel 16V71 engines equipped with one-piece pistons. This configuration was commonly used in older-generation marine propulsion systems and stationary power units. The one-piece piston offers strength and simplicity, making it suitable for applications where rugged reliability is prioritized over lightweight design.

This overhaul kit includes all major wear components needed for a complete rebuild: pistons, liners, rings, bearings, gaskets, and seals. By replacing all internal moving components as a matched set, operators can restore compression, fuel efficiency, and dependability to factory specifications.

Two-Piece Crosshead Piston Overhaul Kit

Later variants of the Detroit Diesel 16V71 Non-Turbo engine utilized two-piece crosshead pistons. These pistons, built with a separate crown and skirt, allow for easier maintenance and can withstand higher thermal loads. The crosshead design is especially advantageous in marine applications where engines are subjected to long periods of heavy, continuous-duty operation.

The two-piece piston overhaul kit provides all the same essential components as the one-piece version but with pistons engineered for the crosshead configuration. Many operators prefer this style when rebuilding because it simplifies future service and extends piston life under demanding conditions.

Cylinder Liners & Related Components

The cylinder liner is the wear surface in which the piston travels, making it one of the most critical components in any Detroit Diesel 16V71 rebuild.

Standard Cylinder Liner Inserts

A direct replacement for standard-size liners, these inserts restore proper sealing and cylinder wall integrity. Ideal for engines being rebuilt within standard bore tolerances.

Oversize Cylinder Liner Inserts (.010 to .030)

When engines have experienced extended wear or damage, oversize liners are required. These liners compensate for cylinder wear and restore proper piston-to-liner clearance, ensuring maximum compression and efficiency.

Liner Shims

Thin liner shims are used during installation to fine-tune liner height, ensuring perfect deck alignment across all cylinders. Even a few thousandths of an inch in liner height variation can cause gasket sealing issues, making these shims essential to a professional-quality rebuild.

Gasket Kits for Detroit Diesel 16V71

Every overhaul requires a comprehensive gasket set. These gaskets maintain proper sealing in critical areas such as cylinder heads, crankcases, water jackets, and intake/exhaust systems.

Complete Overhaul Gasket Kit

This full kit provides every gasket required for a top-to-bottom rebuild. It eliminates the need to source individual gaskets, reducing downtime and simplifying the overhaul process.

Inspection Cover Gaskets

These smaller gaskets are designed for inspection block covers, allowing operators to reseal access points during inspection or partial service without replacing the full set.

Crankshaft Seals & Sleeves

The crankshaft seals protect against oil leaks at the front and rear of the engine. Given the size and operating pressures of a Detroit Diesel 16V71, high-quality seals are essential to prevent oil loss and maintain lubrication.

• Standard Single Lip Seals – Designed for engines operating under normal tolerances.

• Oversize Seals – Used when crankshaft wear requires a slightly larger seal diameter.

• Sleeves for Oversize Seals – Allow worn journals to be resurfaced and sealed effectively, prolonging crankshaft service life.

• Universal Rotation Seals – Accommodate engines configured for either left-hand or right-hand rotation, ensuring flexibility in marine propulsion applications.

Essential Rebuild Tools

No engine rebuild is complete without the proper tools. Diesel Pro Power supplies tools designed specifically for Detroit Diesel engines, ensuring proper installation and reducing the risk of damage.

• Piston Ring Compressors – Allow safe installation of piston rings into liners without breakage.

• Piston Ring Assembly Tools – Ensure proper ring placement and tension, critical for sealing.

• Tune-Up Kits – Provide specialized tools for setting injector timing, adjusting valves, and performing precision service on Detroit Diesel Series 71 engines.

Filtration & Lubrication Components

During an overhaul, filters and oil management systems must also be renewed to ensure clean operation.

• Spin-On Oil Filters – Provide easy replacement and superior filtration compared to older canister-style filters.

• Cartridge Oil Filters – For operators maintaining the original-style filter housings.

• Oil Filter Bases & Wrenches – Ensure proper installation and removal of filters.

By refreshing the lubrication system during an overhaul, you protect your new components from premature wear caused by contaminants.

Cooling System Components

The Detroit Diesel 16V71 generates significant heat during operation, particularly in marine propulsion where engines run under heavy loads. Proper cooling is vital to longevity.

• Thermostats – Available in multiple temperature ratings (160, 170, 180 degrees) to suit different applications and climates.

• Thermostat Seals – Ensure coolant does not leak past thermostat housings.

• Radiator Cleaners – Keep cooling passages clear of scale and buildup.

• Block Heaters – Improve cold-weather starting performance and reduce engine wear during startup.

Electrical & Monitoring Components

Rebuilt engines must be carefully monitored during break-in and operation.

• Temperature Switches – Activate alarms when coolant reaches dangerous levels, protecting against overheating.

• Mechanical & Electric Gauges – Provide accurate readings of oil pressure, water temperature, and other critical parameters. Available in 12V and 24V configurations.

Finishing & Protective Products

After an overhaul, many operators choose to restore the engine’s appearance with OEM-style finishes.

• Detroit Green Paint – Restores engines to their original factory look.

• Primers – Protect bare metal surfaces from corrosion before painting.

These products not only enhance appearance but also add a layer of protection against rust in marine environments.
