[JUDGE - Iter 2]: ### OEM 6240-11-7820 (COVER)
I can see in the diagram two large sheet-metal heat shield cover plates. The larger cover on the **left side** of the diagram is a broad, roughly rectangular plate with multiple bolt holes and a flat profile. The arrow labeled **3** points to this cover, with the note "To Cylinder Block" (ã·ãªã³ããããã¯ã¸). This is the main heat shield cover that mounts to the cylinder block.

| OEM | Description | Callout |
|-----|-------------|---------|
| 6240-11-7820 | COVER | **3** |
| 6240-11-7830 | COVER | **12** |

[gemini-3.5-flash - Iter 2]: 1. **OEM 6240-11-7820** → I can see the left-side heat shield cover component. Tracing the line, **callout arrow 9** points directly to this cover.
2. **OEM 6240-11-7830** → I can see the right-side heat shield cover component. Tracing the line, **callout arrow 10** points directly to this cover.

[mistral:magistral-medium-latest - Iter 2]: 1. Identify the parts listed:
   - Part 1: KEY=6240-11-7820 | OEM=6240-11-7820 | COVER
   - Part 2: KEY=6240-11-7830 | OEM=6240-11-7830 | COVER

3. Match the parts to the callouts based on the visual description:
   - OEM 6240-11-7820 matches the larger cover pointed to by callout 3.
   - OEM 6240-11-7830 matches the smaller cover pointed to by callout 4.

OEM 6240-11-7820 → I can see a larger cover with a complex shape → callout arrow 3 points here.
OEM 6240-11-7830 → I can see a smaller cover with a simpler shape → callout arrow 4 points here.

```markdown
3. OEM 6240-11-7820 → I can see a larger cover with a complex shape → callout arrow 3 points here.
4. OEM 6240-11-7830 → I can see a smaller cover with a simpler shape → callout arrow 4 points here.
```
This solution correctly matches the parts to their corresponding callout numbers based on the visual description in the diagram.

[gemini-2.5-flash - Iter 2]: 1.  **OEM 6240-11-7820 → I can see a component described as 'COVER'. In the diagram, there are two distinct components that could be described as 'COVER': a small L-shaped bracket (callout 11) and a flat rectangular plate (callout 12). Since both parts (6240-11-7820 and 6240-11-7830) are described identically as 'COVER' and the diagram does not provide specific part numbers for callouts 11 and 12, it is not possible to definitively assign 6240-11-7820 to either callout 11 or 12 based solely on the provided information.**
2.  **OEM 6240-11-7830 → I can see a component described as 'COVER'. Similar to 6240-11-7820, it is not possible to definitively assign this part number to either callout 11 or 12 without further distinguishing information (e.g., a more specific description for each part number or a parts list with callout references).**
