The 826G II (Series II) is engineered for maximum reliability in high-volume landfill operations. Maintaining its Cat 3406E engine, Electronic Clutch Pressure Control (ECPC) transmission, and specialized axle guarding systems is essential for preventing debris-related failures. This service manual is the definitive guide for technicians performing hydraulic flow tests, engine overhauls, and electrical circuit diagnostics to ensure the machine maintains peak compaction density.

Machine & Powertrain Information

The Caterpillar 826G II (Prefix AYH) is powered by the legendary Cat 3406E ATAAC diesel engine, providing the high torque rise necessary for pushing heavy waste loads. This manual details the complete service requirements for the engine’s electronic fuel system, including HEUI/EUI diagnostics, valve adjustments, and turbocharger maintenance. It also covers the specialized cooling package designed to handle the high-ambient temperatures and airborne debris common in landfill sites.

The powertrain includes a heavy-duty planetary powershift transmission with electronic control for smooth, responsive shifting. This guide provides detailed instructions for the torque converter with lock-up clutch, the No-Spin differentials, and the oscillating rear axle. Technicians will find critical data for maintaining the Cat Axle Guard System, which protects planetaries and seals from wire-wrap and plastic entanglement.
