STAND 4 UNIVERSAL DRIVE SPINDLE 🚨 PART BROKEN
Defect Diagnosis & Rapid Repair Procedure:
Root Cause: Cold billet entered Stand 4 with entry temperature below 920°C ➔ torque exceeded design yield of 85 kNm ➔ calibrated safety shear pins fractured to protect the main reduction gearbox.

Step-by-Step Fix (from SOP-MNT-RM-04):
1. Apply LOTO padlock to Stand 3-4 Main Drive Motor Circuit Breaker.
2. Remove sheared pin fragments from spindle drive flange sockets.
3. Inspect female coupling splines for burrs or deformation.
4. Insert set of 4 hardened safety shear pins (SAP #SP/MECH/RM/0339).
5. Torque clamping flange bolts to 380 Nm using calibrated torque wrench.
6. Perform 5-minute no-load jog rotation test before re-introducing hot billets.
