CATERPILLAR 7E-0977 Pulley – OEM-Grade Durability for Heavy Equipment Drivetrains

The Caterpillar 7E-0977 Pulley is a precision-engineered component designed to optimize power transmission in a wide range of heavy machinery, including articulated dump trucks (AFX-725, AGF-730), earthmoving compactors (BMR-816F, BKL-815F), and various industrial and truck engines such as LGK-C13, 3NL-3176B, and 7LG-3176. Manufactured using high-strength alloy steel with advanced metallurgy processes, this pulley features exacting dimensional tolerances—typically with a diameter calibrated to fit specific belt profiles and load conditions—ensuring seamless integration within the drivetrain system. Its robust construction guarantees exceptional resistance to wear, corrosion, and fatigue under rigorous operational stresses, making it an indispensable part for maintaining peak equipment performance.

Technically, the 7E-0977 Pulley supports optimal belt alignment and tension, reducing slippage and mechanical losses in power transfer. Its precision-machined grooves and balanced design minimize vibration and noise, contributing to smoother engine operation and extended component lifespan. Suitable for use in both industrial and truck engines (e.g., 1DW-3196, PWG-3512B, KCB-C13) as well as excavators (AKX-345B II, ALD-345B II), this pulley meets or exceeds OEM specifications, ensuring compatibility and reliability. By maintaining drivetrain efficiency, it helps reduce downtime and maintenance costs, ultimately enhancing the productivity of Caterpillar heavy equipment across mining, construction, and earthmoving applications.
