- Precision Tolerance Machining: Tight dimensional tolerances for bearings, shims, and spacers ensure perfect alignment, reducing vibration and extending swivel operational life.
Applicable Operating Conditions
- These NOV swivel spare parts are built fordemanding onshore and offshore drilling environments where reliable swivel operation is critical, including:
- NOV LB-300, LB-500, LB-650 drilling swivel routine maintenance and repairs
- NOV P-500 swivel unit overhaul and component replacement
- TDS 11-SA top drive swivel washpipe and sealing component upgrades
- High-torque, high-pressure rotary drilling operations
- Harsh wellsites with extreme vibration, mud exposure, and temperature fluctuations

Professional Maintenance & Troubleshooting Recommendations
- Seal & Packing Inspection: Check oil seals, packing rings, and washpipe seals for wear or leaks every 1,000 drilling hours; replace worn components immediately to prevent fluid loss.
- Bearing Lubrication & Check: Lubricate bearings via grease fittings per OEM specifications every 500 hours; inspect bearing races for pitting or damage quarterly.
- Shim & Alignment Calibration: Verify bearing shim thickness and alignment during every overhaul to maintain proper preload and reduce excessive wear.
- Washpipe Assessment: Inspect washpipe assemblies for cracks or corrosion every 2,000 hours; replace damaged units to avoid packing failure and fluid contamination.
- Scheduled Overhaul Intervals: Conduct a full swivel overhaul (seals, bearings, packing) every 20,000 drilling hours to prevent catastrophic failure mid-operation.

Field NOV Swivel Fault Repair Cases
Case 1: LB-300 Swivel Oil Leakage
An NOV LB-300 swivel experienced severe lubricant leakage from worn upper/lower oil seal rings. Replacing the OEM oil seal rings (Part No. 6506-0018-00, 6506-0019-00) eliminated leaks, restoring proper lubrication and resuming drilling operations.
Case 2: LB-500 Swivel Bearing Failure
A rig’s LB-500 swivel seized due to a failed Timken bearing and misaligned shims. Installing a new bearing (Part No. 7602-022061) and precision bearing shims restored smooth rotation, avoiding a full swivel replacement.
Case 3: P-500 Swivel Packing Failure
The P-500 swivel experienced mud contamination due to a worn packing set. Swapping in a new OEM packing assembly (Part No. 703429-G3U) fixed the sealing issue, preventing further internal swivel damage.
