⚙️ Key Features
- Engine group hub, 0.184 kg
- Listed for 26 applications across TAD, D and TADH series engines
🔌 Function
Provides the fixed centre on which its gear turns, locating the gear in the drive train and carrying its running loads into the engine casting.
⚠️ Common Signs of Failure
- Growl or rumble from the timing-gear area that rises with engine speed
- Backlash in the drive train that has grown noticeably since last checked
- Metallic debris on the sump magnet or in the oil
- Bearing surface scored, pitted or worn oval, or the hub loose in its location, on strip-down
🛠️ Service Notes
- Hub 21736275 at 0.115 kg covers the same 26 applications, and the larger 21736271 and 21736277 cover 18, so the number is the only safe guide
- Inspect the gear that runs on this hub for matching wear and renew the pair where the bearing surface has picked up
