Custom Application & Conversion Kits
A structured path for applications that do not fit a standard kit.
HKX can provide custom application and conversion kits engineered for many excavator and attachment combinations. These projects address situations where a standard circuit is unavailable, an existing system needs to be repurposed, or the attachment requires functions beyond the machine’s current plumbing.
The process begins with accurate machine and attachment information. HKX reviews the excavator model and serial number, current hydraulic arrangement, attachment functions, required flow and pressure, controls, connection points, and installation constraints before recommending a path forward.
Application Scope
Custom systems are defined by the verified application.
These categories describe common reasons to request custom engineering; they are not universal performance specifications.
- Legacy Machines
- Support paths for older or out-of-production excavators
- Conversions
- Review of existing circuits for a new attachment requirement
- Special Applications
- Planning for uncommon tools and multiple functions
- HKX Support
- Application and installation assistance
Attachment Applications
Start with the operating requirement—not a generic parts list.
Custom projects are evaluated around the actual machine, attachment, work cycle, and existing hydraulic system.
Circuit Conversions
Review whether existing auxiliary hydraulics can be adapted for a different compatible attachment function.
Uncommon Attachments
Plan flow, pressure, controls, drainage, cooling, and connections for specialized tools.
Multiple Functions
Coordinate primary, secondary, rotation, priority-flow, or other required circuits.
System Features & Options
Engineering begins with complete application information.
Custom solutions are scoped from verified machine and attachment data so the proposed system addresses fitment, hydraulic demand, controls, routing, and service access together.
Configuration details
Controls
Selected after the machine, attachment functions, and operator requirements are reviewed.
Recommended Options
May include circuit conversion, added functions, custom routing, specialized connections, electrical integration, case drain, or other application-specific equipment.
Routing & Connections
No universal flow, pressure, or upgradeability value applies. HKX must validate the complete application before specifying components.
Application & Installation Planning
Match the system to the excavator and attachment.
Accurate machine and attachment details help HKX identify the appropriate circuit, components, controls, routing, and installation support.
-
01
Identify the excavator
Provide the manufacturer, model, serial number, current hydraulic equipment, and any relevant machine options.
-
02
Define the attachment
Confirm the attachment make and model, required functions, flow, pressure, case drain, and connection requirements.
-
03
Select controls and routing
Review operator controls, oil sources, component placement, boom and arm routing, and service-access needs.
-
04
Prepare and support the installation
Use the packaged components and instructions, with HKX technical assistance available for installation and future parts identification.
