Parts for Detroit Diesel 2-71 – Blower Section

The Detroit Diesel 2-71 Non-Turbo engine represents one of the most efficient and reliable small two-stroke engines ever designed. Compact yet durable, it delivers consistent performance across a wide range of industrial, marine, and generator applications. Like every engine in the Series 71 family, the 2-71 depends entirely on its Roots-type blower to provide the necessary air for combustion. This positive-displacement blower forces air into the cylinders, ensuring complete scavenging of exhaust gases and consistent fuel efficiency.

At Diesel Pro Power, we provide a complete selection of blower components designed for exact fitment and long-term dependability—whether you’re rebuilding an existing unit or performing routine maintenance. From rebuilt blowers to repair kits, gaskets, seals, and drive components, every part is designed to restore and preserve the legendary performance of your Detroit Diesel 2-71.

Rebuilt Detroit Diesel 2-71 Blowers

A properly functioning blower is the foundation of two-stroke engine performance. Our rebuilt Detroit Diesel 2-71 blowers are fully disassembled, cleaned, and rebuilt to factory specifications. Each unit receives new bearings, seals, and gaskets, and the rotor timing is recalibrated for even, efficient airflow.

Before shipping, each blower is pressure-tested to ensure tight sealing and verified for proper rotor end clearance. The result is a blower that restores factory boost, improves engine responsiveness, and eliminates the oil leaks and air pressure loss that often occur with worn units.

Each rebuilt blower is sold with a refundable core deposit, meaning you can return your old blower for credit after installation. This system ensures sustainability and guarantees that every customer receives a high-quality, authentic Detroit Diesel component that meets OEM-grade standards.

Key benefits of Diesel Pro’s rebuilt blowers:

• Restores optimal air pressure for maximum power output.

• Reduces oil seepage and internal friction through precision sealing.

• Perfect fitment for marine, generator, and industrial Detroit Diesel 2-71 engines.

• Backed by Diesel Pro Power’s commitment to performance and quality assurance.

Blower Repair & Installation Kits

For those maintaining their own engines, our blower repair and installation kits simplify service without compromising on quality.

Blower Repair Kit – Designed for restoring a used blower to peak condition. Each kit includes premium seals, gaskets, and bearings to correct air leaks and re-establish balanced airflow. Rebuilding your blower not only improves performance but also prevents costly damage caused by poor lubrication or imbalance.

Blower Installation Gasket Kit – Provides every essential gasket needed when reinstalling the blower. These precision-cut gaskets prevent pressure loss between the blower and the engine block and protect against oil leaks. They’re resistant to high heat, oil saturation, and vibration—ensuring a long, trouble-free service life.

Together, these kits allow for a complete service of your 2-71 blower assembly—saving time, simplifying maintenance, and restoring engine reliability to factory performance levels.

Drive System Components

The blower drive system connects directly to the engine’s gear train, so alignment and balance are critical. Over time, components such as the shaft retainer and gear cover gaskets can wear, leading to leaks or timing issues. Diesel Pro Power offers durable replacements for these high-wear parts, ensuring that your blower drive remains precise and stable.

Blower Shaft Retainer – Locks the blower shaft securely in place, maintaining rotor timing and preventing excessive end-play.

Blower Drive Gear Cover Gasket – Seals the front drive housing, keeping lubrication contained and protecting against contaminants.

Governor Spring Cover Gasket – Ensures the governor housing remains sealed against pressure loss and oil seepage.

These components may seem small, but their proper function is vital for overall blower efficiency, as even minor misalignment or leaks can reduce boost pressure and engine balance.

Blower Seals and Sleeves

Seals and sleeves play a crucial role in preventing oil intrusion into the air stream. In two-stroke Detroit Diesel engines like the 2-71, even a small oil leak can disrupt airflow, cause fouling, and reduce engine efficiency. Diesel Pro Power supplies high-quality seals that are resistant to heat, oil, and wear, keeping the blower performing at its peak.

Blower Seals – Maintain airtight separation between the oil and air chambers. Proper sealing prevents oil carryover into the intake system, ensuring clean combustion and reduced smoke.

Blower Seal Sleeves – Reinforce sealing surfaces and extend the lifespan of your new seals. Precision-machined for a perfect fit, these sleeves help maintain consistent pressure and reduce friction on the sealing lip.

Gaskets and Lubrication Lines

Maintaining the right pressure inside the 2-71’s air and oil circuits is essential for engine longevity. Diesel Pro Power provides all the necessary gaskets and lines to ensure your blower remains leak-free and properly lubricated.

• Drive Gear Cover Gasket – Prevents oil leaks around the blower gear housing.

• Governor Drive Gasket – Ensures consistent airflow to the governor assembly.

• Hydraulic Governor Gasket – Maintains a tight seal between the blower and the governor drive for reliable operation.

Each gasket is made from high-grade materials designed to handle the high vibration and oil exposure characteristic of Detroit Diesel engines.

Electrical & Accessory Components

To complement your blower service, Diesel Pro Power also offers essential electrical and accessory items that ensure dependable control and finishing touches:

• Shutdown Solenoids (12V & 24V) – Heavy-duty solenoids that provide reliable emergency shutdown capability for both 12-volt and 24-volt systems.

• Teleflex Morse Ball Joint and Clevis Terminals – Marine-grade connectors for throttle and governor cables, providing smooth, precise movement under heavy vibration.

• Detroit Green Paint – Authentic OEM color for finishing engine rebuilds, corrosion-resistant and heat-tolerant for marine and industrial use.

• High-Tack Gasket Spray Sealant – Ideal for securing cut gaskets during installation, ensuring a tight seal even under high-temperature conditions.

The Importance of the Blower in the 2-71

Unlike naturally aspirated engines, the 2-71 cannot operate without a properly functioning blower. This engine’s two-stroke cycle relies on the blower to provide the fresh air needed to purge exhaust gases and maintain compression pressure. A worn or damaged blower can lead to:

• Hard starting or loss of power.

• Increased smoke and unburned fuel.

• Oil leaks or excessive crankcase pressure.

• Uneven idle and fuel inefficiency.

By ensuring your blower assembly, seals, and gaskets are in top condition, you protect the entire engine from premature wear and maintain the crisp throttle response that Detroit Diesel engines are known for.
