Simplfied Service, Low Maintenance Costs

    
• Maintenance is easier with large service doors for access to critical components

    

• Maintenance-free track components and easy to replace track pads lower service costs

    

• Standard ground-level controls and an optional hydraulically operated rotor turning device simplify bit removal and replacement

    

• The accessory drive system allows use of select machine fuctions when the engine is turned off

    

• Electrical system wiring is color-coded and numbered for easy identification and wrapped in a protective, abrasion-resistant nylon braid for longer life

    

• Monitor fluid conditions with regular sampling to help extend change intervals up to 500 hours engine oil, 6000 hours hydraulic oil and 12000 hours coolant

    

• Electronic Control Modules (ECMs) monitor machine systems to alert the operator of performance issues 

    

• VisionLink® takes the guesswork out of managing your entire fleet–regardless of size or equipment manufacturer*–by providing maintenance needs, machine hours, location, fuel usage, idle time, diagnostic codes, and more through interactive dashboards on your mobile device or desktop, helping you make informed decisions that lower costs, simplify maintenance, and improve safety and security on your jobsite

    

• Remote Flash allows you to update onboard software without a technician being present, allowing you to initiate software updates when convenient, increasing your overall operating efficiency**

    

• Remote Troubleshoot allows your Cat dealer to perform diagnostic testing on your connected machine remotely**

    

• Convenient parts availability, dealer locations and service repair kits simplify ordering of high wear components 

* Data field availability can vary by equipment manufacturer and is provided through an application programming interface (API). 
** Must be within cell range coverage.

Sustainability

    
• The Cat C9.3B engine meets U.S. EPA Tier 4 Final, EU Stage V and Korea Stage V emission standards

    

• Cat U.S. EPA Tier 4 Final, EU Stage V, and Korea Stage V Final diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels* up to: 20% biodiesel FAME (fatty acid methyl ester) or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.

    

• Engine Idle Speed Management helps maximize fuel efficiency and reduce greenhouse gas emissions by elevating engine speed to an intermediate idle to complete specific tasks and returning to low idle when finished. 

    

• Automatic Load Control helps you save fuel and reduces greenhouse gas emissions by automatically matching milling speed to engine load for maximum production at peak efficiency.

    

• Standby/Resume pauses major machine functions and lowers engine speed to conserve fuel and helps reduce greenhouse gas emissions during truck exchanges.

    

• Traction Control maintains consistent traction to increase machine efficiency, helps reduce fuel burn and greenhouse gas emissions.

    

• Cat Scheduled Oil Sampling (S•O•S^SM) Services helps reveal excessive wear, contaminated fluids or other “unseen” issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine’s operation and maintenance manual for more information.

    

• Cat Grade with Grade and Slope for cold planers allows for accurate material planning to help reduce overages during the paving process and increase final project quality for a longer lasting road surface.

    

• Don’t waste fuel idling. Cat VisionLink online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.

    

• VisionLink displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.

* Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
