Caterpillar Manuals
Browse service manuals and repair guides for Caterpillar vehicles.
Caterpillar Inc. is the world's largest construction equipment manufacturer, headquartered in Irving, Texas, whose yellow machines have built infrastructure from the Hoover Dam to the Burj Khalifa since the company was founded through the merger of Holt Manufacturing and C.L. Best Tractor Co. in 1925. Cat's product range spans hydraulic excavators, bulldozers, motor graders, wheel loaders, articulated trucks, and mining machinery, with the 797F haul truck capable of carrying a 363-tonne payload — the largest two-axle vehicle in the world. Caterpillar's Tier 4 Final ACERT diesel engine technology and Cat Connect telematics allow remote machine health monitoring and predictive maintenance scheduling. Factory service manuals cover the complete Cat C-series and 3500 engine families, the Cat Advanced Productivity Electronic Control Strategy, the load-sensing hydraulic systems, and the Product Link fleet management system programming.
