Which Machines Share the Same Rubber Tracks

[MikePhua]

The Rise of Track-Driven Compact Equipment
Rubber-tracked compact machines—especially skid steers and compact track loaders (CTLs)—have transformed jobsite mobility over the past two decades. Their ability to traverse soft ground, minimize surface damage, and maintain traction in wet conditions has made them indispensable in landscaping, utility work, and urban construction. Manufacturers like Bobcat, Caterpillar, Case, and Komatsu have all contributed to the rapid expansion of this category, with global sales of compact track loaders exceeding 100,000 units annually by the mid-2010s.
As these machines proliferated, so did the demand for replacement tracks. But with dozens of brands and models on the market, operators often ask: can tracks from one machine fit another?
Track Compatibility Depends on More Than Brand
Rubber tracks are not universally interchangeable. Compatibility depends on several key parameters:

• Track width (typically 300–450 mm for CTLs)
  
• Pitch length (distance between drive lugs)
  
• Number of links or bars (determines overall track length)
  
• Drive lug profile and spacing
  
• Guide system (single or dual flange rollers)
  

For example, a Bobcat T190 uses tracks that are approximately 320 mm wide with 49–50 pitch links. While a Caterpillar 247B may appear similar in size, its undercarriage geometry and sprocket design differ, making direct swaps unreliable without precise matching.
Undercarriage Manufacturers and Cross-Brand Overlap
Interestingly, many compact machines share undercarriage components sourced from a small group of OEM suppliers. Companies like Berco, ITM, and Solideal have supplied track systems to multiple manufacturers, leading to partial compatibility across brands.
Examples of shared undercarriage platforms:

• Early Bobcat and ASV models used similar track widths and roller spacing
  
• Case 420CT and New Holland C185 shared track dimensions due to corporate overlap
  
• Komatsu CK30 and Gehl CTL70 used interchangeable tracks with minor adjustments
  

However, even when dimensions match, drive lug profiles may differ. A mismatch can cause premature wear, derailment, or sprocket damage.
How to Identify a Compatible Track
To determine if a track from one machine will fit another, operators should inspect the inside of the track for stamped specifications. Most tracks include:

• Width (e.g., 320 mm)
  
• Pitch (e.g., 86 mm)
  
• Number of links (e.g., 50)
  
• Manufacturer code or part number
  

Matching these numbers across machines increases the likelihood of compatibility. Additionally, measuring the sprocket diameter and roller spacing can help confirm fit.
In North Carolina, a contractor successfully used take-off tracks from a Bobcat T180 on a Komatsu CK35 after verifying pitch and link count. The tracks lasted over 600 hours before needing replacement.
Used Tracks and Temporary Solutions
In emergency situations—such as a snapped track during a critical job—operators may consider using worn or take-off tracks from other machines. While not ideal for long-term use, these can serve as temporary solutions.
Considerations for used tracks:

• Inspect for cracks, missing lugs, or exposed steel cords
  
• Avoid tracks with deep sidewall gashes or delamination
  
• Use only on low-impact surfaces like pavement or compacted soil
  
• Keep speed and turning to a minimum to reduce stress
  

In Pennsylvania, a crew used discarded tracks with 25% tread remaining for a two-week pavement job. The tracks held up, allowing them to preserve their new set for more demanding terrain.
Field Replacement Techniques
Replacing a rubber track in the field is possible with basic tools and teamwork. The process involves:

• Lifting the machine using bottle jacks or an excavator boom
  
• Releasing track tension by bleeding grease from the idler cylinder
  
• Compressing the track using chains and ratchet binders
  
• Levering the track off with digging bars and crowbars
  
• Installing the new track and re-tensioning with grease gun
  

A two-person crew can complete the swap in under two hours with practice. In Australia, a remote operator replaced both tracks on a Case 420CT using only wood blocks, a chain binder, and a six-foot pry bar.
Recommendations for Long-Term Track Management
To reduce downtime and improve track longevity:

• Keep a spare set of tracks on hand for high-use machines
  
• Rotate tracks between machines if compatible
  
• Track hours and inspect for wear monthly
  
• Avoid aggressive turning on abrasive surfaces
  
• Store unused tracks in a cool, dry place away from sunlight
  

Fleet managers in Texas reported a 30% reduction in track-related downtime after implementing a rotation and inspection schedule across their Bobcat and Case loaders.
Conclusion
While rubber tracks may look similar across compact machines, true compatibility depends on precise measurements and undercarriage design. With careful inspection and matching, operators can sometimes repurpose tracks between brands—especially in urgent situations. Understanding the anatomy of a track and the geometry of the undercarriage is key to making informed decisions. Whether sourcing new tracks or salvaging used ones, a methodical approach ensures safety, performance, and cost-effectiveness in the field.
