When it comes to keeping your Bobcat mini excavator running at peak performance, the top roller—also called the carrier roller—plays a critical role. For models like the Bobcat 331, 337, and 341, part number 7013581 is one of the most sought-after replacements. This precision-engineered component ensures smooth operation, proper track tension, and long-term reliability. Whether you’re maintaining your fleet or tackling a DIY replacement, understanding how this part fits and functions can save you time, money, and downtime.
Understanding the Bobcat 7013581 Top Roller
The Bobcat top roller, part 7013581, is designed for compact excavators such as the 331, 337, and 341. Its function is to guide the track's upper portion, reducing vibration and preventing unnecessary wear. When the roller is worn or damaged, operators may experience uneven track motion, increased noise, or premature track wear. Replacing it promptly helps maintain the excavator’s stability and extends the lifespan of your entire undercarriage system.
A major highlight of this replacement roller is its 2-bolt mounting system, which allows easy installation. Unlike older roller assemblies that required lifting or removing the entire track, this design makes it a true do-it-yourself repair for contractors and equipment owners. With just basic tools, the roller can be installed in less than an hour, minimizing equipment downtime.
Market Trends and Demand in Canada
The demand for high-quality aftermarket Bobcat carrier rollers in Canada has surged, particularly for part number 7013581. Market reports show consistent growth in undercarriage component sales, with a notable average price around $250 CAD per roller. The popularity stems from the affordability, wide availability, and compatibility across multiple Bobcat models such as the 331E, 334, 337, and 341G series.
As urban construction, agriculture, and landscaping projects continue expanding across provinces like Ontario, Alberta, and British Columbia, operators increasingly prefer aftermarket solutions that balance cost-efficiency with OEM-level performance.
AFT parts was born from a collective vision to revolutionize the aftermarket wear parts industry for heavy machinery. Frustrated by the lack of reliable alternatives, a team of experienced professionals set out to create a brand that would provide high-quality, precision-engineered parts for professionals. Through relentless dedication and innovation, AFT parts quickly became the trusted partner for those seeking exceptional performance and durability. Today, we continue to push the boundaries, delivering excellence and empowering heavy equipment professionals to achieve their highest potential.
Core Design and Performance Benefits
The engineering of the 7013581 top roller combines robust steel housing with precision-sealed bearings. This ensures maximum durability, corrosion resistance, and shock absorption under heavy-duty conditions. The outer shell is heat-treated for extended wear life, while the seals protect from dirt and moisture infiltration—two main causes of bearing failure in excavator rollers.
Operators report increased uptime due to lower friction and consistent performance even in challenging environments such as mud, gravel, or frozen conditions. The roller’s compatibility with original Bobcat mounting points ensures a precise fit without modification.
Top Rollers Comparison: Bobcat OEM vs. Aftermarket
This comparison shows how AFT aftermarket rollers deliver near-identical performance to OEM parts for significantly less, while still supporting proper fit, structural balance, and track reliability.
Real User Installations and ROI
A landscaping contractor in Manitoba replaced both top rollers on a Bobcat 337 in under 45 minutes using basic shop tools. With the new rollers installed, track noise decreased by nearly 40%, and uptime improved across multiple job sites. Another user in Quebec noted that the improved bearing design extended service intervals from 900 machine hours to nearly 1,300 hours, reducing maintenance costs by over 20%.
For small fleet operators, that translates directly to better ROI. Over time, a well-maintained set of carrier rollers can prevent costly undercarriage repairs averaging thousands of dollars.
Key Considerations Before Purchasing
When choosing replacement rollers for your Bobcat 331, 337, or 341, ensure the specifications precisely match part number 7013581. The 2-bolt system is critical for correct alignment and tension balance. Verify the supplier’s quality assurance—look for sealed bearings, heat-treated materials, and tested load ratings. Regular greasing and visual inspections every 250 running hours will further enhance component longevity.
Future Trends in Excavator Undercarriage Components
As equipment technology advances, the excavator undercarriage market is moving toward self-lubricating systems, ultra-hard coatings, and smart diagnostics integrated into carrier roller assemblies. Future replacements will likely feature embedded sensors that monitor temperature, vibration, and wear indicators in real time. For now, heavy equipment owners continue to rely on proven parts like the Bobcat 7013581 top roller as the industry benchmark for value and dependability.
Final Takeaway
Whether maintaining a single Bobcat mini excavator or managing a construction fleet, choosing a quality replacement like the 7013581 top roller ensures reliable operation, easier installation, and long-term savings. With its 2-bolt mount design, durable bearings, and $250 CAD aftermarket value, this roller remains one of the most practical solutions available for Bobcat 331, 337, and 341 owners. Replacing your worn carrier roller today means smoother tracks, less downtime, and greater equipment performance tomorrow.
