24 Hour Emergency Service

Komatsu CARE

Every Komatsu Tier 4 Interim construction equipment machine comes standard with Komatsu CARE — a complete service and advanced product support solution that Komatsu and Komatsu Southwest provide to you throughout the entire lifecycle of the machine.  Komatsu CARE features our exclusive complimentary factory-scheduled maintenance program for the first 3 years/2,000 hours.


KOMTRAX is Komatsu’s wireless equipment monitoring system. Through the web you can monitor your machine’s daily activities and performance. Information is provided in several areas.

Preventive Maintenance

Whether you have one machine or fifty, your equipment deserves the same care that Komatsu Southwest gives its own rental fleet. That’s why we offer a Preventive Maintenance Program to help you maintain your equipment. Just tell us which machines you’d like us to cover, and we’ll make sure they’re properly serviced on time by a qualified technician.

Komatsu Oil & Wear Analysis program (KOWA)

The Komatsu Oil & Wear Analysis (KOWA) program uses independent laboratories across the United States to determine how your machine is performing, based on a small sample of oil or other fluids. KOWA detects fuel dilution and coolant leaks, identifies contaminants, and measures wear-metals. Komatsu Southwest technicians will help interpret this information. Regular sampling provides indications of increasing contaminants, so you can schedule repairs at the optimum time.

Rebuild Services

Our remanufacturing services are available for Mechanical Components, Engines, Transmissions, Torque Converters, Final Drives and Hydraulic Cylinders. Components are rebuilt for any brand, any model at OEM specifications.

For replacement components that deliver exceptional value, Komatsu Southwest provides components from our manufacturers’ state-of-the-art remanufacturing and rebuild facilities. These facilities are staffed with highly skilled, experienced craftsmen and knowledgeable customer representatives.

We provide a quick turnaround for these services and can save you up to 40% over buying new.

Repair and Maintenance Programs (RAMP)

Any type of service for your equipment is available at any of our locations throughout Nevada, Utah and Wyoming.


Undercarriage costs consume a significant portion of the average operating cost-per-hour for your track-type equipment; properly maintaining your undercarriage systems is essential. Komatsu Southwest offers a comprehensive undercarriage management program for all manufacturers, including a FREE computer assisted Track Management System (TMS). Take advantage of this free service to reduce unscheduled downtime and operating expense.
