Parts For Detroit Diesel 16V149 Non-Turbo - Blower Section

Parts for Detroit Diesel 16V149 Non-Turbo – Blower Section

The Detroit Diesel 16V149 Non-Turbo engine represents the peak of the legendary 149 Series design — a massive, high-output V16 two-stroke powerplant built for heavy-duty industrial, marine, and power generation use. Known for its durability and distinctive sound, the 16V149 delivers consistent torque and horsepower under extreme conditions. Like all Detroit Diesel two-stroke engines, its operation depends entirely on the performance of its Roots-type blower system , which provides the airflow required for scavenging and combustion. Without the blower, the 16V149 cannot function, making this component one of the most critical systems in the entire engine.

At Diesel Pro Power , we supply a comprehensive selection of blowers, repair kits, gasket sets, and seal sleeves designed specifically for the Detroit Diesel 16V149. Whether you are performing a full rebuild, restoring a marine propulsion engine, or maintaining a generator set, these components deliver the performance, reliability, and precision expected from OEM-grade Detroit Diesel parts.

The Role of the Blower in the Detroit Diesel 16V149

Unlike four-stroke engines, the Detroit Diesel 16V149 requires a blower to operate. This positive-displacement Roots blower delivers pressurized air into the cylinders, pushing out exhaust gases and allowing fresh air to enter for the next combustion cycle — a process called scavenging .

Each 16V149 engine is equipped with two large blowers , one mounted on each bank of the V-block, driven directly by the engine gear train. Together, these units deliver the massive volume of air required to sustain the 16-cylinder, two-stroke cycle. The blowers are precision-machined, balanced, and sealed to maintain the proper air pressure ratio.

If a blower loses efficiency due to worn rotors, leaking seals, or damaged bearings, the results are immediate:

• Reduced power output and slower acceleration.

• Poor fuel economy and increased smoke.

• Difficulty starting, especially under load.

• Higher oil consumption due to air-oil cross-contamination.

A properly functioning blower is therefore not just important — it’s essential. Maintaining clean, well-sealed, and precisely timed blowers keeps your 16V149 running smoothly and ensures long-term reliability in even the harshest conditions.

Rebuilt Detroit Diesel 16V149 Blowers

The rebuilt Detroit Diesel 16V149 blower is a precision-engineered, fully restored component that brings your engine’s air system back to factory performance standards. Each blower is completely disassembled, cleaned, inspected, and rebuilt using premium-grade materials and advanced balancing equipment.

Key features of Diesel Pro’s rebuilt blowers include:

• Complete disassembly and ultrasonic cleaning to remove all carbon, sludge, and corrosion.

• Rotor re-timing and balancing to ensure proper air delivery across all cylinders.

• New bearings, seals, and gaskets for maximum sealing integrity.

• Re-machined surfaces and tested clearances to match Detroit Diesel specifications.

• Pressure and flow testing before shipping to guarantee performance.

Each blower is sold with a refundable core deposit , meaning customers can return their old blower for credit once the new one is installed. This ensures proper recycling of Detroit Diesel castings and allows us to continue supplying authentic, OEM-spec components.

Rebuilt blowers restore lost compression, eliminate uneven air delivery, and reduce the chance of oil leakage — restoring your 16V149 to its full, original power potential.

Blower Repair Kits for 8V149, 12V149, and 16V149

For operators who prefer to rebuild their existing units in-house, Diesel Pro Power offers blower repair kits that include every essential component needed to restore performance. Each kit is designed for one blower and is compatible with the 8V149, 12V149, and 16V149 engines.

These kits typically include:

• Precision-engineered bearings for both rotor shafts.

• Oil and air seals to prevent leaks and contamination.

• Gaskets and O-rings to ensure a perfect seal between housing components.

• Retainers, washers, and fasteners to maintain internal balance.

By using these kits, you can rebuild your existing blowers without sacrificing quality or fitment. Properly rebuilt blowers provide efficient scavenging, stable idle, and consistent air pressure, all while reducing emissions and oil consumption.

Blower repair kits are especially valuable for operators managing fleets or maintaining multiple engines. Rebuilding with these high-quality kits offers significant cost savings while maintaining the integrity of original Detroit Diesel equipment.

Blower Installation Gasket Kits for Detroit Diesel 16V149

When installing a rebuilt or serviced blower, proper sealing is critical. Diesel Pro Power’s blower installation gasket kits are engineered to provide all the necessary gaskets and seals to reinstall one blower unit securely.

Each gasket in the kit is manufactured from heat-resistant, oil-resistant composite material capable of withstanding the high pressures and temperatures typical of Series 149 engines. The kit ensures a precise seal between the blower, intake manifold, and engine block, preventing air and oil leaks that can lead to performance loss or premature wear.

Proper installation with a fresh gasket kit ensures:

• Airtight fit between the blower and cylinder head housing.

• Protection against vibration-induced leaks.

• Long-term resistance to oil seepage and gasket failure.

• Maintenance of consistent boost pressure and scavenging performance.

Replacing gaskets during any blower service is one of the most effective ways to preserve air system integrity and extend the life of your Detroit Diesel 16V149.

Blower Seal Sleeve Kit

The blower seal sleeve kit reinforces the sealing surfaces that protect the blower’s internal bearings and oil system. Over time, the original sleeves can become scored or worn, allowing oil to seep past and enter the air stream — a common cause of smoke and contamination in older engines.

Each sleeve in Diesel Pro Power’s kit is precisely machined to restore the sealing surfaces of the rotor shafts, ensuring tight, even contact with new seals. This helps maintain proper air pressure inside the blower while preventing oil leakage.

Benefits include:

• Longer seal life due to reduced friction.

• Prevention of oil-fuel mixture contamination.

• Restoration of factory-grade pressure balance.

• Lower operating temperatures and reduced maintenance.

These kits are compatible with 8V149, 12V149, and 16V149 blowers, making them ideal for both partial rebuilds and complete overhauls.

Air Control & Accessory Components

In addition to the main blower assemblies, Diesel Pro Power carries essential accessories and related hardware to support proper operation and control.

Teleflex Morse Cable Terminals – Available in ball-joint and clevis styles, these terminals are ideal for connecting throttle or governor linkages in marine and industrial applications. Built from corrosion-resistant materials, they provide smooth, reliable motion even under vibration.

Gasket Spray Sealant – Designed to improve gasket adhesion and prevent blowouts. It’s recommended during reinstallation to hold gaskets in place and ensure uniform sealing under torque.

Detroit Green Paint – For a professional finish after rebuilds or maintenance. It protects against corrosion and provides the iconic factory look associated with Detroit Diesel engines.

Maintenance and Service Tips for 16V149 Blowers

To keep your Detroit Diesel 16V149 performing at its best, regular inspection and maintenance of the blower system are essential. Below are key recommendations followed by marine engineers and power generation professionals worldwide:

1. Inspect blower timing and end clearance during every major overhaul. Rotor misalignment can cause reduced efficiency and metal contact damage.

2. Replace gaskets and seals whenever a blower is removed or reinstalled. Reusing old gaskets often leads to air leaks that degrade performance.

3. Check for oil leaks or carbon buildup around the blower outlet and intake manifold—early signs of seal wear.

4. Lubricate drive gears and inspect for wear to prevent vibration and gear damage.

5. Monitor exhaust color —excessive black smoke may indicate a failing blower seal or insufficient scavenging pressure.

6. Use only high-quality, Detroit Diesel–compatible lubricants and sealants to maintain system integrity.

Following these guidelines ensures that your engine maintains consistent airflow and operates at maximum efficiency.
