Product Name: HP Cylinder Wrench (Part No. 20459001)

Description:
The HP Cylinder Wrench 20459001 is a specialized heavy-duty service tool for the maintenance of high-pressure (HP) cylinders in waterjet intensifier pumps . The tool is used to remove and reinstall the HP cylinder ("jug") from the hydraulic cylinder head during major pump servicing.

The wrench is designed to provide secure grip and adequate leverage for loosening or tightening the HP cylinder threads. The HP cylinder is a heavy component, weighing approximately 55 to 70 lbs , making this specialized tool essential for safe and effective maintenance.

The wrench is typically used with a support cradle tool that holds the weight of the HP cylinder while it is being threaded in or out of the hydraulic cylinder head . Using the correct service tools is critical—improper methods can damage the cylinder threads, scratch the cylinder bore, or injure personnel.

Applications:

• Removing the HP cylinder ("jug") from the intensifier pump assembly to access the plunger, high-pressure seals, and seal buttress components 

• Reinstalling the HP cylinder after seal replacement, plunger replacement, or other maintenance operations

• Used on KMT, H2O Jet, AccuStream, and other standard waterjet intensifier pumps

Features:

• Specialized Design: Specifically machined to fit the flats or external geometry of the HP cylinder for secure engagement 

• Heavy-Duty Construction: Built to withstand high torque loads without bending or breaking

• Corrosion-Resistant Finish: Typically manufactured from steel with a protective coating to resist the waterjet environment

• Safety Enhancement: Provides controlled leverage, preventing slippage that could damage the cylinder or cause injury

• Weight Support Integration: Used in conjunction with support cradle tools to safely handle the heavy HP cylinder 

Maintenance:

Service Procedure:

1. Full Depressurization (Critical): Before any maintenance, shut off the machine, fully depressurize the waterjet and hydraulic systems, and follow lockout/tagout procedures 

2. Support the HP Cylinder: Position a support cradle tool under the HP cylinder to manage its weight before attempting removal 

3. Apply the Wrench: Insert the wrench securely onto the HP cylinder flats or nut

4. Rotate Counter-Clockwise: Use steady, controlled pressure to unthread the cylinder from the hydraulic cylinder head. Support the weight of the cylinder until it completely clears the plunger 

5. Inspect Threads: After removal, inspect the cylinder threads for galling. If galling is present, dress the threads with a file or sandpaper before reinstallation 

6. Lubricate Threads: Prior to reinstallation, apply high-pressure anti-seize lubricant ("Goop") to the cylinder threads and shoulder guides 

7. Reinstall Carefully: Align the cylinder with the plunger using the support cradle. Thread the cylinder in clockwise.

8. Final Tightening: Tighten the HP cylinder hand-tight with the cylinder wrench, then tap the wrench with the palm of your hand to achieve final tightness 

Tool Care:

• Clean the wrench thoroughly after each use to remove grease, water, and metal debris to prevent rust

• Inspect the tool for burrs, cracks, or damage before each use

• Store the wrench in a clean, dry location to protect its precision surfaces
