Parts for Detroit Diesel 12V149 Turbo – Blower Section

The Detroit Diesel 12V149 Turbo represents the pinnacle of two-stroke power and precision. Designed for high-performance marine, industrial, and power generation applications, the 12V149 engine integrates a Roots-type blower with turbochargers to deliver maximum airflow, boost pressure, and combustion efficiency. This twin induction system makes the 12V149 Turbo one of the most advanced engines in Detroit Diesel’s legendary 149 Series — capable of producing exceptional torque, throttle response, and reliability under continuous heavy load.

This section features every major blower and turbo-related component you need to maintain or rebuild your 12V149 Turbo engine. From complete rebuilt blowers to turbo gaskets, clamps, seals, and installation kits — Diesel Pro Power provides premium-grade, ready-to-ship parts trusted by over 40,000 customers in 180 countries.

Detroit Diesel 12V149 Blower – Supercharger Rebuilt

The rebuilt blower (supercharger) for the Detroit Diesel 12V149 Turbo is precision-restored to OEM standards to deliver optimal air volume and pressure to all twelve cylinders. The blower supplies constant airflow for the two-stroke combustion process while the turbochargers provide additional boost at higher RPMs. Together, they ensure efficient fuel burn, improved power, and reduced exhaust temperatures.

Each rebuilt blower undergoes full disassembly, rotor inspection, clearance verification, bearing replacement, and end plate alignment to guarantee a factory-grade rebuild. Every unit is sold with a refundable core deposit, allowing for efficient exchange and reduced downtime.

Replacing or overhauling your blower is essential if your engine shows signs of poor acceleration, uneven idle, oil leakage, or decreased turbo efficiency — all symptoms of worn seals or rotor wear.

Detroit Diesel Blower Installation Gasket Kit for 12V149

When installing or resealing your 12V149 blower, a complete installation gasket kit is mandatory to prevent air and oil leakage between the blower and intake housing. This kit includes all gaskets required to seal a single blower assembly and maintain maximum boost integrity.

Precision-cut from durable, high-temperature materials, these gaskets provide reliable performance in demanding environments like marine propulsion systems and stationary generator applications. Proper gasket sealing ensures that all boost pressure generated by the blower and turbochargers is retained within the intake manifold for optimal performance and fuel economy.

Detroit Diesel Blower Repair Kit for 8V149, 12V149, and 16V149

For operators who wish to rebuild rather than replace their blower, the Detroit Diesel blower repair kit provides every essential component — including bearings, seals, and gaskets — for restoring airflow efficiency and reliability.

Compatible with the 8V149, 12V149, and 16V149 engines, this kit ensures correct rotor alignment, gear balance, and seal containment for a tight, efficient blower assembly. A properly rebuilt blower maintains steady air delivery to the turbochargers, ensuring fast spool-up and balanced combustion throughout the RPM range.

This repair kit offers a practical, cost-effective solution for technicians maintaining multiple 149-series engines across fleets or industrial sites.

Detroit Diesel Blower Seal Sleeve Kit for 8V149, 12V149, and 16V149

The seal sleeve kit ensures proper lubrication control within the blower housing. It prevents oil migration into the air passages, which can otherwise cause carbon buildup and reduced boost pressure.

Each kit contains sleeves, seals, and retainers designed to withstand the high internal pressures and temperatures of turbocharged configurations. Installing new sleeves helps maintain a clean, efficient air stream and supports longer turbocharger life by preventing oil contamination.

This kit covers one blower and is a direct fit for 8V149, 12V149, and 16V149 engines — ensuring that each engine operates at full air handling efficiency.

Turbo System Components for Detroit Diesel 12V149

While the blower provides constant airflow, the turbocharger system on the 12V149 enhances power output by compressing additional air into the engine under load. Maintaining the seals, joints, and fasteners of this system is critical for reliable turbo performance and safety.

Turbo Riser Gasket

The Detroit Diesel turbo riser gasket ensures a perfect seal between the turbocharger and the riser assembly. Its reinforced construction resists heat, vibration, and high exhaust gas pressures — preventing leaks that could lower boost pressure or damage turbo components.

Dimensions: Inner width 2”, inner length 3.75”, outer width 3.75”, outer length 5.5”.

Hi-Temperature Jointing Compound for Turbos

The 762 Hi-Temperature jointing compound is specially formulated for Detroit Diesel and Cummins turbo applications. Rated for up to 760°C (1400°F), it provides a secure seal between turbo flanges, manifolds, and joints exposed to extreme heat. It’s ideal for assembly and maintenance of turbo and exhaust components in marine and heavy-duty engines.

Turbo Clamps – 5.25” and 5.75”

These high-strength turbo clamps are designed to secure the turbo housing and riser components under heavy pressure. The 5.25” and 5.75” diameter clamps maintain tight sealing at all boost levels, preventing exhaust gas leaks that can cause turbo lag and performance loss.

Turbo Bolts, Washers, and Nuts

Each 12V149 turbo assembly requires four sets of bolts, washers, and nuts. These high-tensile fasteners are designed to withstand heat expansion and vibration. Using new hardware during turbo installation ensures secure, leak-free connections and extends the service life of your turbo system.

Turbo Silencer and Filter Element

To reduce noise while maintaining airflow, the Detroit Diesel turbo silencer attaches to the turbo outlet. It minimizes acoustic resonance without restricting boost pressure. The silencer element (filter cover) fits silencers with an 8¼” outside diameter, ensuring optimal air filtration and minimal restriction.

Hump Hoses – Turbo Connection

Hump hoses connect the turbocharger outlet to the blower or intercooler piping. Diesel Pro Power offers multiple diameter configurations:

• 5.5” straight

• 5.5” to 5” reducer

• 6” to 5.5” reducer

Each hose is reinforced to handle high boost pressures and resist heat degradation. These components absorb vibration and movement between engine components, preventing premature cracking or detachment under heavy load.

Teleflex Morse Ball Joint and Clevis Terminals

For engines installed in marine propulsion systems, Teleflex Morse control terminals provide precise throttle and governor response. The ball joint and clevis-type terminals are compatible with 43C series marine control cables, offering smooth, corrosion-resistant linkage between the helm and engine.

These terminals ensure dependable throttle actuation — crucial when controlling a large, turbocharged diesel engine like the 12V149 under varying load conditions.
