This guide explains how to effectively use the Caterpillar 735 Articulated Truck (WWC) service manual, covering all major sections including disassembly, testing, schematics, specifications, system operation, troubleshooting, torque specifications, and the importance of the WWC serial number.

Importance of WWC Serial Number in CAT 735

The WWC serial number prefix is critical when using the Caterpillar 735 service repair manual PDF.

Why WWC Matters:

• Ensures correct parts compatibility
• Matches exact wiring diagrams and schematics
• Provides accurate engine and hydraulic configurations
• Prevents errors during troubleshooting and repairs

For example, a CAT 735 WWC articulated truck may have updates in sensors, transmission systems, or control modules compared to other serial ranges. Always confirm your serial number before starting any repair work.

Disassembly and Assembly for Troubleshooting Access

Even when troubleshooting, accessing internal components often requires proper disassembly and assembly procedures.

Key Areas Covered:

• Engine access and component removal
• Transmission and drivetrain inspection
• Hydraulic pump and cylinder access
• Dump body and articulation joint inspection
• Electrical harness and control modules

Technicians working on CAT D350D or CAT 740 trucks will notice similar layouts, but the WWC-specific manual ensures precise guidance.

Testing and Adjusting Procedures

The testing and adjusting section is essential for accurate troubleshooting.

Includes:

• Hydraulic pressure testing
• Engine performance diagnostics
• Transmission calibration checks
• Brake system testing
• Steering and articulation adjustments

For example, if your CAT 735 has slow hydraulic response, the manual provides step-by-step testing procedures similar to CAT 745C and 740 models.
