Turbocharger Gaskets and Sealing Components

Even the most advanced turbocharger relies on high-quality gaskets to prevent leaks, ensure proper airflow, and maintain pressure. For the Detroit Diesel 471 Turbo engine, Diesel Pro Power offers several gasket options to match different turbocharger housings and connection diameters.

Detroit Diesel Turbo Gasket – 5” Inside Diameter
This gasket features a 5-inch inner diameter and 6.5-inch outer diameter, ideal for sealing between turbo housings and riser flanges. Manufactured from high-temperature resistant composite material, it ensures a leak-free seal even under continuous boost pressure.

Detroit Diesel Turbo Gasket – 5.5” Inside Diameter
This variant accommodates slightly larger turbo flanges, maintaining tight sealing at elevated exhaust temperatures. Its multi-layer design provides superior compression retention and resistance to warping.

Both gasket options are in stock and ready to ship, allowing you to replace worn or damaged seals without downtime. Each gasket is also compatible with other Detroit Diesel 71-series turbo configurations, ensuring cross-application versatility.

Riser Blankets and Turbo Insulation

Turbo risers and exhaust systems on marine Detroit Diesel engines operate at extremely high temperatures. Proper thermal insulation not only improves safety but also enhances efficiency by maintaining heat flow through the turbine.

Riser Blanket for Detroit Diesel (Johnson & Towers)
Coast Guard approved and built with ultra-heavy-duty materials, this riser blanket features stainless steel internal wiring and multi-layer thermal insulation. Designed for demanding marine environments, it prevents engine room heat buildup and protects nearby components from heat damage.

Turbo Blanket – Right or Left Hand Configuration
These turbo blankets are custom-fitted for Detroit Diesel turbo assemblies, offering both right-hand and left-hand configurations. Each blanket is Coast Guard approved and constructed from high-temperature fabrics capable of withstanding direct contact with turbo housings. The stainless steel stitching ensures a long service life even under continuous heat cycles.

Benefits of Proper Turbo Insulation:

• Prevents radiant heat from damaging hoses and electrical components

• Improves turbo efficiency by maintaining optimal housing temperature

• Reduces risk of burns during maintenance or inspection

• Extends life of surrounding gaskets and joints

Turbo Riser Gaskets

The turbo riser gasket connects the turbocharger to the exhaust riser or elbow, sealing the exhaust gas flow from leaks. Diesel Pro Power’s turbo riser gasket for Detroit Diesel engines features precision-cut edges and exact dimensions for a snug fit.

Specifications:

• Inner width: 2”

• Inner length: 3.75”

• Outer width: 3.75”

• Outer length: 5.5”

These gaskets are resistant to high exhaust temperatures and pressure fluctuations, providing consistent performance for both freshwater and saltwater marine applications.

High-Temperature Jointing Compounds

For enhanced sealing performance during turbocharger installation, Diesel Pro offers the 762 Hi-Temperature Jointing Compound, suitable for both Detroit Diesel and Cummins turbo systems.

This compound withstands temperatures ranging from 550°C to 760°C, providing an extra layer of sealing assurance for joints exposed to vibration and thermal expansion. It’s ideal for assembling turbo housings, flanges, and exhaust manifold connections.

Key Benefits:

• Prevents gas leaks in high-temperature joints

• Protects gaskets and metal surfaces from corrosion

• Simplifies disassembly during future maintenance

• Sold in 225-gram tubes, easy to apply with a brush or nozzle

Turbo Oil Return Gaskets

Oil circulation is critical to turbocharger performance. The Detroit Diesel Turbo Oil Return Gasket ensures a secure seal between the turbo oil drain and the engine block or oil return tube. Measuring 3 inches wide and 1.5 inches long, this gasket prevents leaks that can cause oil contamination or turbo damage.

A properly installed oil return gasket maintains steady lubrication flow, which is vital for keeping the turbo bearings cool and clean. Always replace the oil return gasket whenever servicing or replacing the turbocharger.

Turbo Clamps, Bolts, Nuts, and Washers

Turbo assemblies require precise clamping force to ensure safe operation. Diesel Pro offers all necessary fasteners for Detroit Diesel 471 Turbo engines, including:

Turbo Clamp – 4.25” Diameter
This heavy-duty clamp fits 4-53, 4-71, 6V53, and 6V92 turbo connections. Constructed from corrosion-resistant steel, it provides a secure, vibration-resistant hold even in harsh marine environments.

Turbo Bolts, Nuts, and Washers
Each turbo installation typically requires four bolts, four nuts, and four washers to secure the assembly. These fasteners are engineered to withstand high vibration, thermal expansion, and salt exposure without loosening or corrosion. Diesel Pro’s hardware components are manufactured from marine-grade steel, ensuring long-term reliability.

Installation Tip:
When installing your turbocharger, torque all bolts in a cross-pattern sequence to evenly distribute pressure and prevent flange warping. Always use new washers to maintain consistent clamp load.

Turbo Silencer Filter and Airsep Components

Efficient air filtration is vital for maintaining turbocharger and engine performance. Diesel Pro Power offers high-quality Turbo Silencer Filters and Airsep filtration components for Detroit Diesel 471 Turbo systems.

Turbo Silencer Filter Element
This filter element fits housings with an 8 1/4" outer diameter. Designed to trap dust and airborne contaminants, it helps maintain consistent airflow and protect the turbo impeller from damage.

Airsep Filter – Tapered, 9” Diameter x 9” Length
Made by Airsep, this high-capacity air filter ensures superior air intake quality. Its tapered design optimizes airflow while minimizing resistance, contributing to smoother turbo operation and reduced exhaust smoke.

Airsep Spring Set
The Airsep spring set, compatible with Detroit Diesel Series 53, 71, and 92 engines, includes four 9.5" long springs. These maintain the tension and position of the Airsep filter assembly, ensuring stable operation even under engine vibration.

Airsep Filter Cleaning Kit
To extend filter life, Diesel Pro provides a complete cleaning kit suitable for Airsep systems used on Detroit Diesel engines. Regular cleaning helps maintain airflow efficiency and prolong filter lifespan, saving on replacement costs.

Hump Hoses and Turbo Air Connections

Proper hose connections between the turbocharger, aftercooler, and intake manifold are crucial for maintaining boost pressure and airflow integrity. Diesel Pro Power’s line of Detroit Diesel Hump Hoses covers multiple diameter transitions and configurations:

• 5” to 4” Hump Hose Reducer – Ideal for adapting turbo outlets to smaller intake tubing.

• 5” x 5” Straight Hump Hose – Standard size for many 471 turbo configurations.

• 5.5” to 5” Reducer Hose – Designed for minor diameter transitions in air systems.

• 6” to 5.5” Reducer Hose – Suitable for larger marine setups or modified air systems.

• 6” x 6” Straight Hose – Provides direct connection between large turbo and cooler inlets.

Each hose is reinforced with heat-resistant silicone and multiple fabric layers to withstand high pressure and temperature. The flexible hump design allows slight movement between connected components, reducing stress and preventing air leaks.

Maintenance Tip:
Inspect all hump hoses for soft spots, cracks, or oil residue during routine maintenance. Replace any hose showing deterioration to prevent boost loss or debris ingestion.
