These machines rely on steel track chains composed of links, bushings, and pins that wear over time due to friction, impact, and environmental exposure. Replacing or rebuilding track chains requires high-force pressing equipment capable of disassembling and reassembling components with precision.
A track press typically applies between 100 and 300 tons of hydraulic force to remove or install pins and bushings. The jig—the fixture that holds the track in place—is the heart of this operation. It must be rigid, modular, and adaptable to various track sizes and configurations. Without a properly designed jig, the press cannot deliver force evenly, risking damage to components or injury to technicians.
Jig Design Fundamentals and Material Selection
An effective track press jig includes several key elements:

• Base frame constructed from high-strength steel I-beams or box tubing
  
• Adjustable saddles or cradles to support track links
  
• Removable side plates to accommodate different chain widths
  
• Pin alignment guides to ensure axial force application
  
• Safety shields or deflection guards to contain debris
  

• Pin pushers with hardened steel tips
  
• Bushing extractors shaped to grip outer diameters
  
• Spacer blocks to isolate specific links
  
• Hydraulic return cylinders for controlled retraction
  

• Galling: A form of wear caused by adhesion between sliding surfaces, often resulting in material transfer and surface damage.
  
• Yield Strength: The stress at which a material begins to deform plastically, beyond which permanent deformation occurs.
  
• Spacer Block: A rigid insert used to isolate or support components during pressing operations.
  
• Return Cylinder: A hydraulic actuator that retracts tooling after force application, improving cycle time and safety.
  

• Regular inspection of welds and fasteners
  
• Use of pressure-rated hydraulic hoses with burst protection
  
• Installation of emergency stop switches and pressure relief valves
  
• Operator training in force alignment and load path awareness
  

• Reduced setup time
  
• Easier transport between job sites
  
• Compatibility with multiple press models
  

• Design for at least 1.5x the maximum expected press force to ensure structural integrity
  
• Use hardened steel for contact surfaces to prevent deformation
  
• Include alignment pins and guides to maintain axial force direction
  
• Test jig under load with dummy components before live operation
  
• Maintain a log of press cycles and tooling wear for predictive maintenance
