SIS 2.0's responsive Cloud-based design allows you to login from any device giving you the parts and service information at your fingertips when you need it.

Since 1933 HOLT CAT has offered legendary Cat power systems service and support, from extensive parts inventories to preventive maintenance, generator support, diagnostics and 24/7 emergency service. We have dedicated and tenured staff dedicated to meet your unique needs, providing solutions and partnering with you to get the job done.

The choice of a full Cat Certified Rebuild or a customized rebuild matched to your specific needs. Your CAT machine wasn't built to have one life. It was built to have several. And our 70,000 square foot rebuild facility was built to make each of those lives every bit as productive as the first. Thanks to our efficient, modernized process, smaller Cat machines that you never thought were options for a rebuild are now perfect candidates. Let us help you maximize your investment. Power train components are completely disassembled and all critical engineering updates are incorporated.

Undercarriage is the lifeblood of your machine and maintenance costs can consume over 50 percent of the maintenance budget on your track machines. When you partner with HOLT CAT to manage your undercarriage, we will help you reduce downtime and operating costs, while dramatically increasing uptime and productivity.

Regular fluid testing can give you a picture of your machine's health and find problems before they occur. SOS measures wear in specific components by determining the amount of wear particles in the fluid from that component with real-time test results online. Plus, you don't need an advanced degree in chemistry to take advantage of your oil, coolant or fuel sampling results.
