️ Installing Connecting Rods to Cross Head Pistons – Detroit Diesel 8V71 | DIESELPRO.COM


In this video, Diesel Pro Power demonstrates how to install connecting rods onto cross head pistons during the long block assembly of a Detroit Diesel 8V71 engine. This step is essential to forming a strong, balanced connection between the piston assembly and the rotating crankshaft, ensuring smooth performance under the demanding conditions of a two-stroke diesel engine.


The 8V71 is part of the iconic Detroit Diesel Series 71, trusted across marine, industrial, transit, and military applications for its simplicity and durability. The 8V71 uses a cross head piston design—a two-piece piston configuration that includes a piston crown and a separate skirt, connected by a wrist pin and a slipper (button) bearing. This design reduces side loading and extends piston life.
