Product Name: Jackbolt Lubricant (Part No. 400001-2)

Description:
This component is a specialized high-pressure thread lubricant designed specifically for waterjet cutting systems. It is formulated for lubricating jackscrews (also known as jackbolts or tie rod bolts) and their corresponding threaded bores during the assembly and maintenance of intensifier pumps, high-pressure cylinders, and end cap assemblies . The lubricant is engineered to withstand extreme pressures, typically up to 60,000–94,000 PSI, and is crucial for ensuring that fasteners can be torqued accurately and disassembled without galling or seizure.

The "Jackbolt Lubricant" is distinct from general-purpose greases. It is often referenced in OEM manuals by specific product names, which may include JL-M grease or similar high-pressure assembly compounds . It is a direct replacement or equivalent for JL-M lubricant as specified in KMT and H2O Jet maintenance procedures and is compatible with H2O Jet, Flow, KMT, AccuStream, OMAX, WSI, and BFT waterjet systems.

Applications:

• Lubricating jackbolts, tie rods, and mounting studs during intensifier pump assembly and major maintenance .

• Coating the internal threads of the High Service Exchange Cycle (HSEC) or hydraulic cylinder head before installing jackbolts .

• Preventing thread galling and seizure on high-stress, large-diameter fasteners under high preload.

• Used during cylinder head installation, end cap fastening, and any procedure requiring accurate torque application on critical bolts.

• Ensuring future disassembly is possible without damaging threads or seizing components.

Features:

• Extreme Pressure Rating: Specifically formulated for the high clamping loads and pressure cycling of waterjet intensifiers (60,000–90,000+ PSI) .

• Anti-Galling & Anti-Seize: Prevents cold welding, galling, and seizing of stainless steel and alloy threads under heavy loads .

• High Film Strength: Contains solid boundary lubricants to maintain a protective film between metal surfaces under extreme compression .

• Water & Corrosion Resistant: Protects threads from moisture and corrosion in wet waterjet environments.

• Accurate Torque Application: Ensures a consistent coefficient of friction, allowing fasteners to be tightened accurately to manufacturer specifications .

• Compatibility: Formulated to be compatible with seal materials and safe for use in waterjet hydraulic systems.

Maintenance:

When to Use (Critical Applications):

• Every Jackbolt Installation: Apply liberally to the full length of the threads and to the ends of the jackbolts, as well as to the internal threads in the HSEC or cylinder head, during every reassembly .

• High-Pressure Cylinder Assembly: Essential for lubricating the large threads on high-pressure cylinders to prevent galling during installation .

• Major Pump Overhauls: Always use fresh lubricant when rebuilding the intensifier pump.

• Seized Fasteners: If galling occurs during disassembly, repair the surfaces, clean thoroughly, and apply fresh lubricant before reinstalling .

Application Guidelines:

• Ensure Lubricant is Well-Mixed: Before use, verify the lubricant is well mixed and not dried out due to age .

• Apply Liberally: Unlike anti-seize which requires a thin film, jackbolt lubricant is often applied generously to the full length of the threads to ensure proper hydraulic tensioning and lubrication.

• Clean Threads First: Before applying, ensure threads are clean, dry, and free from old lubricant, debris, or corrosion.

• Torque to Specification: After applying lubricant, tighten fasteners to the specific torque values listed in the equipment service manual using a proper torque wrench.

• Do Not Mix with Anti-Seize: This product is a dedicated assembly lubricant, not a standard anti-seize. Use as directed by the OEM manual .
