How to use this SAA4D102E-2A-B4 engine hub
- Identify the engine variation. The full engine code matters because suffixes can indicate different arrangements or applications.
- Match the part number when possible. A part number match is stronger than a description-only match.
- Watch for serial breaks. Komatsu engine parts can change by serial number, option code, or machine application.
- Use diagrams only after narrowing the system. Diagrams and callout tables belong on lower-level component or diagram pages where the image and table are specific to that section.
