Parts for Detroit Diesel 12V71 Turbo – Blower Section

The Detroit Diesel 12V71 Turbo engine is one of the most powerful and reliable models from the legendary Series 71 family. Known for its two-stroke design, turbocharged efficiency, and marine-grade durability, this engine depends heavily on the performance of its blower system to maintain proper air delivery and combustion balance. The blower is a critical component that forces air into the cylinders, ensuring the precise air-to-fuel ratio needed for optimal power and responsiveness—especially under high-load conditions often seen in marine, industrial, and generator applications.

Diesel Pro Power provides a complete catalog of blower components and accessories for the 12V71 Turbo engine. Whether you need a fully rebuilt blower assembly, replacement shafts, couplings, seals, or gaskets, our inventory ensures that your Detroit Diesel engine continues running at peak performance. Every product in this section meets OEM standards or exceeds them for fit, durability, and reliability.

Rebuilt Detroit Diesel Blowers and Components

The Detroit Diesel Blower for 6V71 and 12V71 (rebuilt) is the centerpiece of this section. It’s expertly remanufactured to restore full compression and boost characteristics while maintaining precise air delivery across all cylinders. Each blower is sold with a refundable core deposit and includes new bearings, rotors, and seals to ensure performance equal to or better than new. This is ideal for marine vessels, heavy-duty trucks, and industrial power units using the 12V71 Turbo.

Complementing the main blower assembly are the blower oil tube assemblies—available in both 1/4" x 1/8" and 1/8" x 1/8" sizes—to ensure consistent lubrication flow to the blower bearings. Diesel Pro Power also supplies the blower repair kit for Series 71 turbo engines, a comprehensive solution that includes seals, bearings, and gaskets, allowing you to rebuild your blower in-house with professional-level results.

Installation and Coupling Components

Proper blower installation is crucial for balanced airflow and correct gear alignment. The blower installation gasket kit for 12V71 and 12V92 Turbo engines covers both blowers, offering all the required seals and gaskets to complete a top-end service. To maintain mechanical connection and torque transfer between the blower and accessory drive, Diesel Pro Power stocks blower couplings, hub plates, and accessory drive hubs for thin 48 spline shafts—essential for secure operation at high RPMs.

For further support, parts like the blower shafts (available in both 5" and 5.86" lengths, depending on marine or industrial setup) and blower shaft retainers ensure smooth, aligned rotation within the housing. Precision-machined sprockets, chains, and clamps for blower drive systems are also available to keep the blower system operating under correct tension and synchronization.

Gaskets, Seals, and Bearings

Maintaining an airtight and oil-tight seal throughout the blower system is key to preventing performance losses and premature wear. Diesel Pro Power offers every critical gasket used in blower installation, including the blower gasket screen, striker plate gasket, end plate gasket, and block-to-blower gasket. These components are designed to withstand the extreme heat and pressure of turbocharged engines while maintaining leak-free operation.

Supporting these are blower seals and seal sleeves, which ensure reliable sealing around the rotating shafts. The bearing for accessory and blower gear drive (Series 71 and 92) is another essential part, machined for long-lasting service and resistance to high rotational stress—ideal for demanding turbo applications.

Airflow and Accessory Components

Beyond the blower itself, maintaining proper air and crankcase ventilation is vital. The air box kit for 12V71 and 12V92helps maintain clean and regulated airflow, while the valve assembly for the air box breather prevents pressure buildup. For turbocharged engines, Diesel Pro Power also provides aftercooler gaskets and hydraulic governor gaskets, ensuring proper sealing for boosted intake systems and precise fuel control.

Additional accessories include the shutdown solenoids available in 12V, 24V, and 32V configurations—allowing for safe engine shutdowns in marine and industrial applications—and Teleflex Morse control terminals (clevis and ball joint styles) compatible with 43C marine cables.

Maintenance Essentials and Finishing Touches

To complete any professional rebuild, Diesel Pro Power carries Detroit Diesel green engine paint for authentic restoration and gasket spray sealant for easy installation and leak prevention. These finishing supplies are often overlooked but make a major difference in ensuring a durable, professional-grade rebuild that stands up to marine and industrial demands.
