Parts For Detroit Diesel 12V149 Non-Turbo - Blower Section

Parts for Detroit Diesel 12V149 Non-Turbo – Blower Section

The Detroit Diesel 12V149 is one of the most powerful engines in the legendary two-stroke Detroit Diesel family. With twelve cylinders arranged in a V-configuration and a massive displacement of over 1,700 cubic inches, this engine is designed to move heavy loads and power vessels or industrial equipment that demand extreme reliability. Central to that performance is the blower, also known as the supercharger — a precision-engineered component that supplies the air necessary for the two-stroke cycle to operate efficiently.

This section provides everything needed to service or replace your 12V149 blower system, from complete rebuilt units to repair kits, gasket sets, and sealing components — all sourced from Diesel Pro Power’s trusted inventory, used by more than 40,000 customers in 180 countries worldwide.

Detroit Diesel 12V149 Blower – Rebuilt

The rebuilt Detroit Diesel 12V149 blower is a factory-grade, remanufactured supercharger designed to restore full breathing performance to your non-turbo 12V149 engine. Each unit is disassembled, cleaned, and inspected to ensure all tolerances meet or exceed OEM specifications. Precision-fit rotors and end plates ensure proper air delivery to each cylinder bank, maintaining even combustion and smooth idle.

A high-quality rebuilt blower eliminates power loss caused by worn rotors or leaking seals. It’s essential for engines that show reduced air pressure, uneven firing, or excessive oil accumulation in the airbox. Sold with a refundable core deposit, this component offers an environmentally responsible and cost-effective alternative to new units.

For marine operators, industrial users, and standby power systems, the rebuilt 12V149 blower from Diesel Pro Power ensures reliable air induction for peak engine output and fuel efficiency.

Detroit Diesel Blower Installation Gasket Kit for 12V149

During blower removal or replacement, a new installation gasket kit is required to ensure airtight and oil-tight reassembly. This kit includes all gaskets and seals necessary to mount a single blower to the 12V149 block, preventing air leaks that could affect compression balance and combustion.

Each gasket is constructed from high-temperature, oil-resistant materials suitable for continuous operation in marine and industrial environments. Proper sealing between the blower and intake housing also prevents unfiltered air from entering the cylinders, protecting internal components from damage.

If you are rebuilding or reinstalling your blower, Diesel Pro Power’s gasket kit saves time and ensures a precise fit — no cutting, trimming, or fabrication required.

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

The blower repair kit provides everything needed to restore functionality to a worn blower assembly without replacing the entire unit. This kit includes precision bearings, oil seals, gaskets, and other critical components for a complete rebuild.

The 12V149 shares design similarities with its smaller and larger siblings — the 8V149 and 16V149 — so this repair kit fits all three configurations. Each component is engineered for proper alignment of the blower rotors and shaft assembly, ensuring smooth airflow and stable boost pressure across all twelve cylinders.

Rebuilding your existing blower with this kit helps extend its service life, minimizes downtime, and restores original airflow characteristics. It’s an economical solution for fleets, ship operators, and power plant technicians who maintain Detroit Diesel 149-series engines in continuous operation.

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

Proper oil control inside the blower depends on the seal sleeve assembly, which prevents lubricant migration from the gear train into the airbox. This seal sleeve kit includes the critical retaining sleeves, seals, and supporting hardware for one blower.

Over time, worn seals can lead to oil leaks that reduce air delivery efficiency and foul internal engine components. Installing new sleeves and seals ensures the blower operates with full oil separation, helping maintain consistent pressure levels and preventing carbon buildup inside the intake manifold.

All parts are manufactured from corrosion-resistant materials suitable for both marine and stationary applications, guaranteeing long-term durability even under high temperature and continuous duty cycles.

Teleflex Morse Ball Joint and Clevis Terminals – 1/4" Marine Cable

Efficient throttle and governor control are vital for Detroit Diesel engines, particularly in marine propulsion systems. The Teleflex Morse ball joint and clevis-type terminals are high-precision fittings designed for 43C marine control cables, ensuring smooth linkage movement between the engine’s governor and the helm or control station.

The ball joint terminal allows angular movement for flexible routing of cables, while the clevis terminal offers secure pin connection at the throttle lever or governor arm. Both components are built from corrosion-resistant metals to withstand harsh saltwater environments.

Replacing worn terminals ensures consistent throttle response, smoother control input, and long-term reliability in demanding marine conditions.
