Caterpillar SIS 7.2021 Service Information System, Parts Catalog & Repair Manuals

Caterpillar Service Information System, commonly referred to as CAT SIS, is a technical information platform used for identifying parts, reviewing service procedures, troubleshooting faults, and maintaining Caterpillar machinery and power systems.

The 7.2021 release provides access to illustrated parts information and electronic service documentation for a wide range of Caterpillar construction equipment, industrial engines, power plants, attachments, and related systems.

CAT SIS combines the electronic parts catalog and technical service information within a single searchable application, allowing technicians to locate machine-specific information using serial numbers, product families, component groups, and part references.

Important Technical Information

CAT SIS is a service information and electronic parts catalog platform. It does not directly communicate with Caterpillar electronic control modules and does not replace Caterpillar Electronic Technician.

CAT SIS is used for:

• Parts identification
• Repair documentation
• Technical specifications
• Troubleshooting procedures
• Maintenance information

Caterpillar Electronic Technician is required separately for:

• Machine communication
• Fault-code retrieval
• Live data
• Diagnostic tests
• Controller configuration
• ECM programming
• Calibration procedures

The information displayed in CAT SIS should be selected according to the correct machine model, serial number, engine arrangement, and component configuration.
