Parts for Detroit Diesel 671 Non-Turbo - (2 Valve Head Type) - Blower Section

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.

Blower Kits

• Repair Kit (Series 71 – Natural) – Replaces bearings, seals, and gaskets to restore pressure and reduce rotor noise.

• Installation Gasket Kit – 6-71 – Includes blower-to-block and cover gaskets for tight airbox sealing and oil control.

Shafts, Couplings & Drive Components

• Coupling (Thin 48-Spline) – Transfers torque from the gear drive to the blower input without backlash.

• Blower Shafts – Available in several 48-spline lengths:

• ≈ 12.125" (standard inline)  ≈ 11.06" (short cover)  ≈ 12.00" (marine / Allison).

• Retainer & Rotor Gear Hub – Hold shaft alignment and maintain precise rotor timing.

• Hydraulic Pump Drive Hub – Couples blower shaft to hydraulic pumps on marine units.

Lubrication & Sealing Parts

• Oil Tubes – Deliver oil to the blower drive and governor for reliable lubrication.

• Drive Gear & Screen Gaskets – Prevent air or oil leaks around the blower cover.

• Blower-to-Block & End Plate Gaskets – Maintain correct airbox pressure.

• Seals & Sleeves – Keep oil out of the intake; sleeves restore worn sealing surfaces.

• Drive Cover Hose (≈ 2.75" × 0.95") – Replaces aged rubber to stop seepage.

Air Intake & Silencer

• Industrial Air Cleaner (4" inlet) – High-flow filter for dry or dusty environments.

• Marine Silencer (6-71) – Cuts intake noise without restricting airflow; corrosion-resistant construction.

Governors, Breathers & Electrical

• Air Box Breather Valve – Balances crankcase pressure and reduces oil mist.

• Hydraulic Governor Gasket – Seals governor to drive housing.

• Shutdown Solenoids – 12 V / 24 V – Reliable fuel cut-off for service or emergency stops.

Marine Control Hardware

• Teleflex / Morse Ball-Joint & Clevis Terminals (¼", 43C) – Precision throttle and governor linkage ends with corrosion resistance for marine use.

Finishing Supplies

• Detroit Green Paint – Heat-resistant OEM color for corrosion protection.

• High-Tack Gasket Spray – Improves gasket adhesion and prevents leaks during assembly.
