1. Core Overview & Target Application Brief
This comprehensive spare parts catalog is precision engineered exclusively for the IRI-160D workover rig, covering 1996-2002 NOV-manufactured units and 1998 IRI-160D specific models, including compatible components for Drawworks 1287/2042, pneumatic systems, hydraulic systems, crownblock, swivel S200, rotor drive, and transfer case subsystems. Tailored to meet the specialized needs of workover rig maintenance teams, oilfield service contractors, drilling operators, and equipment rental firms, these parts target the most disruptive field pain points: brake system failure, pneumatic valve leaks, hydraulic control malfunctions, gearbox wear, seal degradation, and cardan shaft damage that cause costly unplanned downtime and safety hazards during well workover, well servicing, and remedial drilling operations.
2. Detailed Product & Component Specifications
The IRI-160D workover rig replacement parts line features high-durability, field-proven components built to withstand the extreme mechanical stress, pressure fluctuations, and harsh environmental conditions of onshore well workover operations. Each part is crafted from premium materials—heat-treated alloy steel for shafts and gears, oil-resistant nitrile rubber for seals, corrosion-resistant brass for pneumatic valves, and high-tensile components for brake systems—with strict dimensional tolerances (±0.002 inches for critical mating surfaces) to ensure perfect fitment with original NOV IRI-160D rig hardware. This catalog covers all critical subsystems of the IRI-160D, eliminating the risk of fitment errors and performance gaps common with generic aftermarket parts, and includes direct cross-references for legacy and new part numbers for simplified sourcing.
3. Key Functional Specifications
- System Compatibility: Engineered for IRI-160D rig pneumatic (operating pressure 90-120 PSI) and hydraulic (operating pressure up to 3000 PSI) systems, with full compatibility for Drawworks 1287/2042 and swivel S200 assemblies.
- Wear Life Metrics: Heat-treated gear and shaft components offer a 25,000+ operating hour service life; industrial-grade oil seals resist fluid degradation for 2,000+ hours; pneumatic valve components maintain tight sealing for 15,000+ actuation cycles.
- Load Rating Compliance: Load-bearing components (cardan shafts, drive flanges, brake parts) meet the IRI-160D’s rated workover load capacity, adhering to API 4F structural safety standards.
- Legacy Part Cross-Compatibility: All parts include direct replacements for legacy NOV codes, ensuring seamless upgrades for 1996-2002 IRI-160D rigs without modification.

4. Field Fault Repair Cases (Real-World Scenarios)
3.1 Case 1: Drawworks Brake System Failure (Onshore Workover Site)
Issue: IRI-160D rig drawworks brake failed to hold load, creating a safety hazard during tubing pulling. Root cause: Worn brake tape (11200502) and faulty brake mechanism (11318000) for Drawworks 2042. Repair: Replaced brake tape, brake mechanism, and related rollers; adjusted brake clearance and tested load holding. Outcome: Restored full brake functionality, met API safety standards, and resumed workover operations without delays.
3.2 Case 2: Pneumatic Valve Leak (Remote Well Servicing)
Issue: Air pressure loss in the IRI-160D pneumatic system, causing slow valve actuation and rig control issues. Root cause: Degraded Bendix R8 valve (IA347) and faulty pilot valve (108-762-90). Repair: Replaced faulty pneumatic valves, pressure-tested the air system, and cleared air line blockages. Outcome: Eliminated air leaks, restored consistent pneumatic pressure, and regained full rig control responsiveness.
3.3 Case 3: Hydraulic Control Panel Malfunction (Workover Rig Overhaul)
Issue: IRI-160D hydraulic control panel failed to regulate fluid flow, disrupting drawworks operation. Root cause: Faulty hydraulic control panel assembly (10930423) and worn control valve (10979072). Repair: Swapped damaged control panel and valve, bled air from the hydraulic system, and calibrated pressure settings. Outcome: Restored stable hydraulic flow, resumed normal drawworks operation, and completed rig overhaul on schedule.
