🔌 Function

Transmits rotation between the components it links inside the engine, carrying the torque and locating them on its bearing surfaces.

⚠️ Common Signs of Failure

• Knock, whine or rumble that follows engine speed
• Play felt when the shaft is rocked in its bearings
• Bearing journals scored, blued or picked up
• Metal in the oil or on the filter element
• Keyway, spline or drive feature worn or twisted

🛠️ Service Notes

• Check the bearings and bushes the shaft runs in and renew them with it - a new shaft in a worn bore will not last
• Look at the oil feed to the shaft before reassembly, since oil starvation is the usual cause
