🔌 Function

Fastens the fan guard to its mounting, holding the guard rigid against the airflow and vibration of a running engine.

⚠️ Common Signs of Failure

• Fan guard rattling, moving or sitting proud of its mounting
• Screw found loose, backed out or missing
• Elongated or pulled mounting hole in the guard
• Thread stripped or seized in the tapped hole
• Rust streaks running from the fixing point

🛠️ Service Notes

• This fixing holds a fan guard - never run the engine with the guard loose, incomplete or removed, and check every fixing is present and tight before starting
• The old number 21699972 is also replaced by 984753 and 984754, and 22072117 is also replaced by 984753, so an order against either of those numbers may call for more than this screw alone
• At 0.227 kg this is much, so it is not interchangeable with the general-purpose flange screws around it
