Parts for Detroit Diesel 6-71 Non-Turbo (2-Valve Head) – Blower Section

The Detroit Diesel 6-71 Non-Turbo depends on its Roots-type blower to clear exhaust and deliver fresh air to the cylinders. A well-sealed, properly timed blower is essential for smooth idle, strong acceleration, and long engine life. This catalog includes rebuilt blowers, gaskets, couplings, shafts, seals, and accessories for a complete, leak-free installation.

Rebuilt 6-71 Blowers

• Left-Hand (LH) – Mounts on the left side when viewed from the flywheel.

• Right-Hand (RH) – Mounts on the right side.

Each unit is fully remanufactured with new bearings, seals, and gaskets, rotors timed to spec, and tested for pressure and endplay. Sold with a refundable core deposit. Correct rotation ensures proper airflow and governor alignment.

Parts for Detroit Diesel 6-71 Non-Turbo (4-Valve Head) – Blower Section

The Detroit Diesel 6-71 (four-valve head) is a cornerstone of the Series 71 two-stroke family. On these engines, the Roots-type blower isn’t just an add-on—it’s the heartbeat of the air system, scavenging exhaust and packing fresh air for every power stroke. This section brings together the rebuilt blowers plus every seal, gasket, shaft, and accessory you need to service the blower drive on in-line 6-71 applications (including marine setups with Allison gears).

Rebuilt 6-71 Blowers (Left-Hand & Right-Hand)

Two orientations are common on the 6-71:

• Left-Hand (LH) Mount – Blower mounted on the left side of the engine when viewed from the flywheel.

• Right-Hand (RH) Mount – Blower mounted on the right side of the engine.

Each rebuilt unit is fully disassembled, cleaned, inspected, and fitted with new bearings, seals, and gaskets. Rotor timing and clearances are set to factory spec so you get stable idle, crisp throttle response, and strong scavenging under load. Units are sold with a refundable core deposit for cost savings and sustainability.

When to choose LH vs. RH: match the orientation your engine/installation was built with—this keeps your governor, intake ducting, and accessory drives aligned without modifications.

Parts for Detroit Diesel 6-71 Turbo – Blower Section

The Detroit Diesel 6-71 Turbo combines the classic Series 71 two-stroke architecture with turbocharging for stronger mid-range torque, improved scavenging, and cleaner operation. On these engines, the Roots-type blower still does the heavy lifting for air scavenging, while the turbocharger boosts overall airflow. Keeping the blower, its drive, and all sealing surfaces in top form is essential to preserve turbo response, balance airbox pressure, and protect the rotors and gears from premature wear.

Rebuilt 6-71 Turbo Blowers (Left-Hand & Right-Hand)

Choose the orientation that matches your engine:

• Left-Hand (LH) Blower – Mounted on the left side when viewed from the flywheel.

• Right-Hand (RH) Blower – Mounted on the right side when viewed from the flywheel.

Every rebuilt unit is completely disassembled, cleaned, inspected, and assembled with new bearings, seals, and gaskets. Rotor timing and end clearances are set to factory spec so the blower works in harmony with the turbo, delivering crisp throttle response and strong scavenging. Units are sold with a refundable core deposit for cost savings and sustainability.

Fitment tip: Always match the original LH/RH placement to keep your governor, intake ducting, and accessory drive aligned without modification.
