⚠️ Common Signs of Failure

• Bearing rumble or overheating
• Oil leakage around housing seals
• Shaft misalignment or vibration
• Cracked housing or fretted mounting face
• Excessive bearing movement

🛠️ Service Notes

• Clean and inspect the housing bore before assembly — scoring, ovality, discoloration or signs of a bearing having spun in the bore mean the housing must be replaced, not reused
• Press or draw bearings in squarely, supporting the housing properly and applying force to the housing and bearing race that is being fitted; never pull a bearing home using the shaft or the mounting fasteners
• Fit new seals and O-rings, and lubricate the bearing and seal lips with the grease or oil specified in the workshop manual for your engine before closing up
• Follow the manual's shimming, endfloat and preload procedure for the assembly rather than judging it by feel
• Turn the assembly by hand before it goes back into service; it should rotate smoothly with no roughness, tight spots or unexpected play
