Buying a 100-Ton C-Frame Track Press for Undercarriage Work

[MikePhua]

Track Presses and Their Role in Heavy Equipment Maintenance
A track press is a specialized hydraulic machine used to assemble and disassemble track chains on crawler-type equipment such as bulldozers, excavators, and loaders. These machines apply controlled force to press pins and bushings in or out of track links, ensuring proper alignment and tension. The most common configuration for field and shop use is the C-frame track press, which allows open access to the work area and accommodates various track sizes.
Terminology Note

• C-Frame: A press frame shaped like the letter “C,” allowing side access to the track chain.
  
• 100-Ton Capacity: The maximum force the press can exert, suitable for medium to large crawler machines.
  
• Pin and Bushing Replacement: A common maintenance task involving removal and installation of hardened steel components in track links.
  
• OTC: A well-known manufacturer of hydraulic presses and tooling systems.
  

Why a 100-Ton C-Frame Is Ideal
A 100-ton C-frame track press strikes a balance between portability and power. It can handle most track chains found on mid-size dozers (e.g., CAT D6, Komatsu D65) and excavators up to 40 tons. While larger presses exist, they are often stationary and require extensive shop infrastructure. The 100-ton unit can be mounted on a bench or mobile frame and operated with a hydraulic pump—manual, air-over-hydraulic, or electric.
Advantages include:

• Versatility: Compatible with multiple track sizes and brands.
  
• Accessibility: Open frame design simplifies alignment and pin removal.
  
• Portability: Can be moved between job sites or mounted in service trucks.
  
• Cost Efficiency: Lower operating costs compared to outsourcing track work.
  

Sourcing and Market Availability
Track presses are manufactured by companies such as OTC, ESCO, and DuraPress, with new units ranging from $8,000 to $15,000 depending on configuration. Used presses are often available through auction sites, equipment dealers, or fabrication shops. When buying used:

• Inspect the frame for cracks or weld repairs.
  
• Verify cylinder seals and pressure ratings.
  
• Confirm tooling compatibility with your track chain sizes.
  
• Request photos and dimensions before purchase.
  

In North Dakota, a contractor sought a 100-ton C-frame press to support a growing fleet of CAT and Deere dozers. After months of outsourcing pin and bushing work, he calculated that owning a press would save over $12,000 annually in labor and downtime. He eventually sourced a refurbished OTC unit from a mining surplus auction and retrofitted it with custom tooling for D7 track chains.
Tooling and Accessories
A track press is only as useful as its tooling. Essential accessories include:

• Pin pushers and receivers matched to track link dimensions
  
• Bushing press adapters
  
• Alignment jigs for consistent setup
  
• Hydraulic pump and hose kit rated for 10,000 psi
  

Some operators fabricate their own tooling using hardened steel and lathe work, especially when working with older or uncommon track types.
Safety and Operation Tips

• Always wear eye protection and gloves during press operation.
  
• Use a pressure gauge to monitor hydraulic force and avoid overloading.
  
• Keep tooling lubricated and free of debris.
  
• Train operators in alignment and press sequencing to prevent damage.
  

Conclusion
A 100-ton C-frame track press is a strategic investment for contractors, fleet managers, and equipment rebuilders. It enables in-house track maintenance, reduces downtime, and improves control over undercarriage service schedules. Whether sourced new or used, the key is matching press capacity and tooling to your equipment lineup—and ensuring safe, consistent operation with trained personnel.
