Product Name: Intensifier Assembly Tie Rod (Part No. 20458191)

Description:
The Tie Rod (P/N 20458191) is a critical structural fastener for the intensifier pump assembly in a waterjet cutting system . As a primary component of the intensifier stack, it runs the entire length of the pump, passing through both End Bells and the Hydraulic Cylinder to secure the assembly .

Manufactured from high-strength, heat-treated alloy steel, the tie rod is engineered to withstand the extreme separation forces generated inside the intensifier during high-pressure operation up to 60,000–94,000 PSI (approximately 4,137–6,480 bar) . Its function is to provide the clamping force that holds the entire intensifier assembly together, ensuring the End Bells remain perfectly parallel and that internal seals are properly compressed for leak-free operation . This component is cross-referenced under part numbers 100017-1 (H2O Jet) and TL-001005-1 (60K systems) .

Applications:

• Secures the End Bells, Hydraulic Cylinder, and other components into a rigid intensifier stack (Intensifier Assembly 20458728) .

• Maintains the alignment and preload necessary for high-pressure cylinder and hydraulic seals to function .

• Used during major pump overhauls, seal replacements, or complete intensifier rebuilds.

• Compatible with H2O Jet, KMT, AccuStream, and other standard 60k-94k intensifier systems .

Features:

• High-Strength Alloy Steel: Heat-treated for tensile strength and fatigue resistance under millions of pressure cycles .

• Precision Threads: Machine-cut threads on both ends ensure accurate torque application and secure fastening with hex nuts (P/N 20460489) .

• Non-Wear Component: The tie rod itself is not a high-wear consumable; however, the threads are subject to stress.

• Critical Alignment Tool: Proper torquing of the tie rods is essential to prevent oil manifold damage .

Maintenance:

When to Inspect:

• Visible Thread Damage: Stripped, galled, or corroded threads prevent proper clamping and require immediate replacement.

• Intensifier Leakage: External oil or water leaks from between sections of the pump stack may indicate uneven tie rod torque.

• Difficult Assembly: If the tie rod binds when threading through the End Bells, the threads are likely damaged.

• Poor Alignment: During rebuilds, if the End Bells cannot be squared properly, a bent tie rod may be the cause.

Inspection and Replacement Guidelines:

• Full Depressurization (Critical): Before any maintenance, fully depressurize the waterjet system and follow lockout/tagout procedures .

• Removal: Remove hex nuts (P/N 20460489) from the tie rod ends and slide the rod out of the intensifier stack .

• Lubrication: Apply a thin layer of high-pressure anti-seize lubricant to the threads during reassembly to prevent galling.

• Replacement Criteria: Replace the tie rod immediately if threads are damaged, the rod is bent, or if stress cracks are visible.

• Torque Compliance (Critical): Tighten the hex nuts on both ends in a crossing (staggered) pattern to the specific torque value (e.g., 160 Nm / 120 ft-lbs). Use an alignment fixture to square the End Bells .
