CAT IT24F Joystick Conversion: Feasibility, Process, and Considerations

[MikePhua]

Overview of CAT IT24F Joystick Retrofit Options
The CAT IT24F was originally designed with traditional pedal and lever controls. Retrofitting this model with joystick controls—either for loader or steering functions—has been considered by operators wanting a more modern, ergonomic interface. However, converting older CAT machines like the IT24F is complex, expensive, and often less practical than expected.
This guide explores what’s involved, the benefits, limitations, and real-world experiences from operators who have considered or attempted joystick retrofits.
Why Operators Consider Joystick Conversion

• Comfort and Ergonomics: Joysticks reduce repetitive stress on ankles and legs, which is especially important for operators with limited mobility or long workdays.
  
• Precision Control: Hand-operated joysticks offer smooth, proportional hydraulic control—ideal for loader work.
  
• Modernization: Bringing older machines closer to current control standards.
  

Despite these advantages, conversion on older models often proves costly, technically challenging, and may not deliver the expected return on investment.
Technical Requirements and Challenges

• Actuators: Installing joysticks typically requires dual hydraulic actuators (around $800 each) to control valve spools.
  
• Joystick Assemblies: Control sticks are several hundred dollars each.
  
• Control Module or Computer: Required to interface joystick movement with hydraulic functions (typically $300 or more).
  
• Wiring Harness and Additional Components: Adapters, updated wiring, potentially $500+ for loom and switches.
  
• Dealer Reprogramming: Necessary to enable new controls—often only licensed dealerships can perform this step.
  

Total conversion costs can approach the value of a newer machine already outfitted with native joystick controls.
Alternative Adaptation Methods
Some operators suggest mechanical retrofit shortcuts:

• Cable-operated joystick kits: These are used in smaller tractors or backhoes and require adapting existing valves with cable control plates.
  
• Custom linkage fabrication: Using rods and heim joints to connect joysticks to valve levers mechanically.
  

These do-it-yourself options may be less expensive but offer limited smoothness and precision.
Real-World Operator Feedback
From experienced operators:

“You will need two actuators, a new computer, and a wiring loom. Honestly, it’s not worth the money.”
“It is almost impossible to convert, unless you want to spend almost the same amount as for a one-year-old machine.”

Others advise testing new joystick-equipped models before deciding, since sensitivity, lag, and responsiveness vary widely.
Procedure Summary for Joystick Retrofit

• Evaluate: Is joystick control worth the investment for this machine?
  
• Plan: Identify parts needed—joysticks, actuators, control unit, harness.
  
• Install:
  • Remove or bypass foot and hand levers.
    
  • Mount joysticks and actuators securely.
    
  • Run wiring and calibrate control module.
    
• Reprogram: Dealer or specialized technician needed to enable the controls.
  
• Test & Adjust: Fine‑tune for sensitivity and safety.
  

Pros and Cons
Pros:

• Ergonomic benefits, especially for operators with mobility limitations
  
• Potential precision advantages for loader tasks
  

Cons:

• High cost and complexity
  
• Requires dealer intervention and calibration
  
• May introduce control lag or oversensitivity
  
• Not universally compatible with older mechanical hydraulics
  

Case Example: Operator Perspectives
One user who switched to a joystick loader after an ankle injury later observed:

“I moved from a foot/hand machine to a joystick. Mainly due to an ankle injury. But joystick controls are not all I thought—they’re easy to overreact with. There’s a slight lag and unintended movement when terrain is bumpy.”

This underscores the importance of understanding joystick sensitivity and machine behavior before undertaking a retrofit.
Terminology Explained

• Actuator: A hydraulic or electro-hydraulic device that moves a valve or mechanism in response to electronic control.
  
• Control Module / Computer: An electronic unit that processes joystick signals into commands for hydraulic movement.
  
• Cable-Operated Valve: A traditional valve operated by physical cables rather than electronics or hydraulics.
  
• Flow Sensitivity: The responsiveness of a hydraulic system to joystick input. High sensitivity can cause jerky movement, especially on uneven terrain.
  

Conclusion
While ambitious and potentially helpful for some operators, converting a CAT IT24F to joystick control is usually not cost-effective or straightforward. For most users, the complexity, expense, and calibration needs outweigh the ergonomic gains—especially when used machines with factory-installed joysticks are available for a similar investment.
However, for those committed to retrofitting, mechanical cable systems or actuator-based kits combined with dealer programming may offer a workable—though advanced—solution. Testing joystick-equipped machines before committing is highly recommended to ensure comfort, control, and operator satisfaction.
