Detroit Diesel 6V92 Turbo Overhaul Kits & Engine Rebuild Components

The Detroit Diesel 6V92 Turbo is one of the most recognized two-stroke V6 engines of the Series 92 family. Designed for performance, versatility, and long service life, this turbocharged model has been widely used in marine vessels, buses, fire trucks, military vehicles, and industrial equipment. With its compact design and impressive power-to-weight ratio, the 6V92 Turbo has remained a trusted choice for operators who demand reliability under heavy-duty and continuous-use conditions.

Over time, however, even the most robust Detroit Diesel engines will show signs of wear. Pistons, liners, rings, gaskets, bearings, and seals naturally deteriorate with thousands of operating hours. To restore power and efficiency, Diesel Pro Power offers complete inframe overhaul kits and supporting components for the Detroit Diesel 6V92 Turbo. These kits provide everything required to rebuild your engine to factory-level performance, whether it’s a Turbo Intercooled (TI) or Turbo Aftercooled (TA) version.

Complete Inframe Overhaul Kits for Detroit Diesel 6V92 Turbo

Overhaul Kit for 6V92 Turbo Intercooled (TI)

The Turbo Intercooled version of the 6V92 uses an intercooler to reduce intake temperatures, improving combustion efficiency and lowering stress on the engine. Our overhaul kit for the 6V92 TI includes replacement pistons, liners, piston rings, pins, retainers, seals, and a comprehensive gasket set. This kit is engineered for operators who require maximum uptime in marine, transit, and industrial environments where reliability is critical.

Overhaul Kit for 6V92 Turbo Aftercooled (TA)

The Turbo Aftercooled (TA) engine variant uses an air-to-air aftercooler to deliver cooler, denser intake air, resulting in higher horsepower and improved durability. The 6V92 TA overhaul kit provides the same full component package as the TI kit but designed specifically for aftercooled applications. By selecting the correct kit, you maintain compression ratios, airflow, and combustion characteristics exactly as Detroit Diesel intended.

Cylinder Liners and Liner Inserts

The 6V92 relies on wet-type cylinder liners, which are easier to replace and provide better cooling. These liners must be installed with precision, and Diesel Pro Power provides all the necessary options for a proper rebuild.

• Standard Liner Inserts – Ideal when your engine block is in original condition and requires no machining.

• Oversize Liner Inserts – Designed for situations where the block has been re-machined or shows wear. These ensure the liner seats securely, preventing coolant leaks and ensuring proper combustion chamber sealing.

For efficient service, we also supply the Detroit Diesel Cylinder Liner Puller, a professional-grade tool designed to safely remove liners without damaging the engine block. This tool is especially important in fleet and marine applications where downtime is costly.

Piston Rings and Tune-Up Kits

No overhaul is complete without new piston rings. The Detroit Diesel 6V92 ring sets restore compression, reduce oil consumption, and ensure smoother engine operation. Each ring set is designed to match OEM tolerances, with high-strength materials to withstand the intense pressures of a turbocharged two-stroke engine.

To complement overhaul kits, Diesel Pro Power also offers Detroit Diesel tune-up kits for Series 53, 71, and 92 engines. These kits include specialty tools and components that allow mechanics to adjust timing, fuel delivery, and governor settings with precision, ensuring your rebuilt engine performs at its best.

Gasket Kits for Detroit Diesel 6V92 Turbo

Every inframe rebuild requires a fresh set of gaskets. Over time, gaskets lose their sealing capability due to heat cycles, vibration, and pressure.

• Complete Overhaul Gasket Kit – Includes head gaskets, manifold gaskets, water pump gaskets, oil seals, and all critical sealing components.

• Inspection Gaskets – Available for block covers, these are essential for periodic inspections without the need for a full kit.

With new gaskets, you eliminate coolant leaks, oil leaks, and compression loss—restoring the reliability Detroit Diesel engines are known for.

Bearings and Main Components

Main Bearing Caps

The main bearing cap supports the crankshaft and keeps it in alignment during operation. Diesel Pro Power offers new replacement bearing caps for the Detroit Diesel 92 Series, ensuring that your rotating assembly is properly supported during high-load operation. Replacing worn bearing caps during an overhaul reduces the risk of crankshaft misalignment and premature bearing wear.

Crankshaft Seals and Sleeves

Seals are critical for preventing oil leaks and maintaining pressure balance. The Detroit Diesel 6V92 Turbo requires both front and rear crankshaft seals, available in several configurations:

• Front Seals – Offered for both right-hand and left-hand rotation crankshafts, designed with Teflon sealing for durability under turbocharged pressures.

• Rear Seals – Available in single-lip and double-lip versions, with options for standard or oversize fit. Operators can choose universal rotation seals or seals designed specifically for right-hand or left-hand rotation engines.

• Crankshaft Sleeves – When wear is present, oversized sleeves allow proper installation of new seals, ensuring a secure fit and preventing oil leakage.

Replacing these seals during every overhaul ensures reliable lubrication and minimizes the risk of contamination.

Fuel Filtration and Service Components

A rebuilt engine must be protected from contaminants. The fuel system is one of the most critical areas of maintenance for two-stroke Detroit Diesel engines.

• Primary Fuel Filters – Available in spin-on or cartridge designs to trap larger contaminants before they reach the injection system.

• Secondary Fuel Filters – Provide finer filtration, ensuring only clean fuel reaches the injectors.

• Filter Wrenches – Diesel Pro Power offers filter removal tools designed to handle both fuel and oil filters safely and quickly.

Replacing filters during an overhaul is a simple step that extends the life of injectors and protects the precision components inside the fuel system.

Oil Filtration System

Clean oil is the lifeblood of the Detroit Diesel 6V92. Rebuilt engines require new oil filters to prevent premature wear.

• Spin-On Oil Filters – Easy to replace, designed for durability and high-flow capacity.

• Cartridge Oil Filters – An alternative configuration used on some Detroit Diesel engines, offering the same high level of filtration.

• Oil Filter Wrenches – Specialized tools available for multiple engine types, including Detroit Diesel, Cummins, and Caterpillar, making filter servicing faster and safer.

Cooling System Components

Turbocharged engines like the 6V92 TI and TA produce additional heat, making cooling system components especially important.

• Thermostats – Available in 170° and 180° options depending on operating environment.

• Thermostat Seals – Ensure proper sealing and coolant flow through the thermostat housing.

Replacing thermostats during an overhaul prevents overheating and ensures your Detroit Diesel runs at the correct temperature for maximum efficiency.

Specialized Tools for 6V92 Rebuilds

Professional mechanics and fleet operators understand the value of proper tools. Diesel Pro Power provides:

• Cylinder Liner Pullers – For safe and damage-free liner removal.

• Piston Ring Assembly Tools – Designed for both Detroit Diesel and Cummins engines, ensuring piston rings are installed correctly and securely.

• Filter Wrenches – Essential for servicing spin-on and cartridge filters.

These tools make rebuilding the 6V92 Turbo faster, safer, and more efficient.

Applications of the Detroit Diesel 6V92 Turbo

The 6V92 Turbo is found in a wide variety of demanding environments, including:

• Marine Applications – Fishing vessels, tugboats, workboats, and ferries where continuous duty is required.

• Transit Buses and Coaches – Widely used in public transport systems during the 1980s and 1990s.

• Fire and Emergency Vehicles – Where high horsepower and reliability are critical.

• Military Vehicles – Armored personnel carriers and logistics vehicles have used the 6V92 for decades.
