Technician Field Workbench
FIELD WORKSPACEWO Created / Awaiting TechAssigned Work Order: WO-2026-0047 • Asset: Tower 04 (Bearing Assembly B17)
Technician: Sarah Lin (Lead Specialist)
Why this inspection is required
Abnormal vibration velocity (7.80 mm/s) has deviated +17.8% from the historical operating baseline over the previous 36 hours. Bearing housing temperature has concurrently risen to 68°C.
What to inspect
- Bearing raceway condition & acoustic spalling check
- Radial & axial alignment runout (< 0.05 mm)
- Mounting bolt torque specification (280 Nm)
- Lubrication viscosity & thermal particulate audit
Governing Engineering ProcedureMP-B17-04 — Class B17 Bearing Inspection Protocol §4.2
Field Verification Checklist
Execute each item in accordance with SOP-MECH-07 safety rules.
4 CHECKS MANDATED
01.Bearing Race & Acoustic Condition
Inspect outer/inner raceway for micro-spalling, pitting, or acoustic frequency distortion.
02.Radial & Axial Alignment Check
Verify shaft alignment using precision dial gauge (tolerance < 0.05 mm).
03.Mounting Bolts & Harmonic Damper Torque
Verify all 8 mounting bolts meet 280 Nm torque specification.
04.Lubricant Quality & Seal Integrity
Inspect Mobilith SHC 220 grease for thermal discoloration and particulate contamination.
