🔌 Function

⚠️ Common Signs of Failure

• Worn or damaged mounting surfaces
• Excessive run-out or vibration
• Damaged threads or key/mating features
• Fretting between the shaft and attached components
• Impact or corrosion damage discovered during overhaul

🛠️ Service Notes

• Handle and store the shaft so the bearing journals and seal running surfaces stay unmarked — a nick on a seal track will cause a leak that no new seal will cure
• Remove the protective coating and check the shaft for straightness, scoring, pitting and stepped wear at the journals, splines and seal areas before fitting
• Lubricate journals, splines and seal surfaces with clean oil of the grade specified for the assembly as it goes together, and renew the seals and any single-use nuts or locking devices disturbed on removal
• Draw bearings and couplings on square with a press or drawing tool that loads only the correct race — hammering a bearing onto a shaft marks the races and can distort the shaft
• Set end float, backlash and shim thickness to the values in the workshop manual for your unit, then turn the assembly by hand to confirm it is free before applying power
