Detroit Diesel Blower Teardown (8V71) | DIESELPRO.COM

In this video, Diesel Pro Power walks you through the disassembly of a Detroit Diesel 8V71 blower, one of the most vital components in a two-stroke Detroit Diesel engine. This teardown offers a hands-on look at how the blower is assembled internally, and what goes into servicing or rebuilding it properly.

The blower, also known as a roots-style air scavenging pump, plays a critical role in the operation of Detroit Diesel two-stroke engines like the 8V71. It forces air into the cylinders to flush out exhaust gases and deliver the fresh charge needed for combustion, essential for engine performance, fuel economy, and emissions control.

Whether you’re rebuilding an 8V71 engine or just want to understand the inner workings of its air handling system, this video provides valuable visual guidance.

⚠️ Important Note: This video is for demonstration purposes only and does not include safety instructions or torque specifications. Always refer to the official Detroit Diesel service manual when performing actual disassembly or installation work.

Why You Should Buy Your 8V71 Rebuilt Blower From Diesel Pro Power

The Detroit Diesel 8V71 depends entirely on its blower to operate. As a two-stroke engine, it cannot breathe, scavenge exhaust gases, or produce power without a properly functioning Roots-style blower. When the blower is worn — causing low power, hard starting, smoke, poor fuel economy, and uneven cylinder temperatures — replacing it with a high-quality rebuilt unit is essential.
