🔌 Function

Carries the cooling fan on its bearing and drive face, taking the belt load and keeping the fan running true.

⚠️ Common Signs of Failure

• Rumble or growl from the front of the engine that follows engine speed
• Fan visibly wobbling or running out of true
• Play felt when the fan is rocked by hand
• Belt wearing on one side or throwing off
• Grease weeping from the hub, or a hot bearing after a run

🛠️ Service Notes

• The serial breakpoint is the deciding detail, as this hub is for engines up to serial number 2071165481
• Check the fan blades and the belt for damage while the hub is off, and renew a fan with any cracked blade
• Set belt tension to specification after fitting, as an over-tight belt is the usual cause of hub bearing failure
