Detroit Diesel 3-71 Non-Turbo (2-Valve Head) – Camshaft & Related Components

The Detroit Diesel 3-71 non-turbo engine with a 2-valve head configuration is a cornerstone of the classic Series 71 line, known for its simplicity, durability, and efficient two-stroke design. This three-cylinder engine has powered countless industrial, marine, and generator applications worldwide thanks to its rugged dependability and ease of maintenance. At the center of its operation lies the camshaft—responsible for precisely timing the valve and injector actions that define the smooth, rhythmic operation of every Series 71 engine.

Over decades of service, the camshaft and its related components endure high rotational stress and load. Wear in these parts can cause performance issues like poor timing, injector misfires, or uneven compression. Replacing these critical components with precision-engineered parts restores the 3-71’s signature performance, reliability, and efficiency.

Diesel Pro Power offers a full selection of premium aftermarket camshafts and related components specifically designed for the Detroit Diesel 3-71 non-turbo 2-valve head engine, delivering OEM-level precision, fit, and longevity.

Camshaft Assemblies for Detroit Diesel 3-71 Non-Turbo (2-Valve Head)

The camshaft controls both the fuel injector timing and valve operation on this two-stroke engine. Diesel Pro Power provides camshafts that are precisely machined and balanced to OEM standards. Each camshaft is heat-treated and surface-hardened for long-term durability and reduced wear. With proper camshaft timing, the 3-71 maintains efficient fuel delivery, clean combustion, and balanced performance across all three cylinders.

Camshaft Bearings, Bushings, and Gears

The smooth operation of a camshaft depends on the integrity of its supporting components. Diesel Pro Power supplies high-quality camshaft bearings, bushings, and drive gears specifically engineered for the 3-71 non-turbo engine. These parts ensure correct alignment and minimize vibration, extending the life of both the camshaft and engine block. Proper replacement of these components during an overhaul helps maintain consistent oil pressure and precise mechanical timing.

Rocker Arms, Shafts, and Valve Train Components

The 2-valve head configuration uses rocker arms to translate camshaft motion into precise valve lift and injector movement. Diesel Pro Power’s rocker arms, shafts, and adjustment hardware are manufactured to match factory tolerances, ensuring perfect synchronization between the camshaft and cylinder head components. Replacing these parts along with your camshaft ensures optimal compression, smoother idle, and reduced fuel consumption.

Seals, Gaskets, and Thrust Hardware

To complete your camshaft service, Diesel Pro Power carries all the required sealing and alignment components, including camshaft seals, thrust washers, and gaskets. These parts maintain oil integrity, prevent leaks, and keep lubrication flowing evenly across all camshaft journals. Proper sealing also helps reduce internal friction, protecting the camshaft and bearings from wear during extended operation.
