Never underestimate the power of a blown fuse to bring your new, used or rental heavy equipment to a complete standstill. The job of fuses is to break the connected circuit to avoid an overloaded circuit, which could be a fire hazard. Our 139-5345: FUSE is a 5 amp fuse that will provide protection for your electrical components inside your Cat equipment. This fuse can be used in wheel-type loaders, engines, off-highway trucks, mini hydraulic excavators, and more. Our 233-0098: FUSE-SLOW BLOW is made for the mini hydraulic excavators. Fuses come in different sizes and can look different. Plus, they are designed for specific operating parameters. Ask one of our customer associates for the perfect fuse for your Cat machine today.


There are many aftermarket upgrades you can make to your Cat equipment in order to improve their functionality and performance. In the case of our Caterpillar motor graders, we offer many options, including our 481-2128: STABLE BLADE. This stable blade is a retrofit for motor graders that helps to detect and reduce the machine’s bounce while in use before it causes hiccups in your work. This great electrical component from Caterpillar can be enabled through the message display and can only be engaged when the throttle is in gears 1F through 5F. If you are looking for the perfect aftermarket Cat parts, contact a Wagner dealer to learn more today.


We rely on gauges to constantly provide us feedback so that we understand the state of our equipment at any given moment in time. From the fuel gauge to the speedometer, these electrical components are crucial to machine health. Our 288-5736: INDICATOR (TACHOMETER) helps to monitor your engine in order to tell you engine RPM so that you can operate your machinery at an optimal level. This tachometer features an analog gauge that displays 0 to 3000 RPM, is durable, and features a translucent dial with a backlight for easy visibility and readability.

Horns and Alarms

Horns and alarms are critical for safety reasons. It’s crucial that your Cat heavy machinery can warn others of their movements so that your employees, operators, and job site can stay safe. Our 369-0134: HORN GROUP-ELECTRIC emits an audible warning so that everyone will know where the machine is in space. This horn comes with a pigtail connector. Our 5D-6998: HORN GROUP-AIR is another one of our great warning horns that fits perfectly on your Caterpillar machinery. Built to withstand the extreme weather conditions of the outdoors, this horn will ensure everyone goes home safe at the end of the day.

Our Cat machines utilize various switches to accomplish tasks that help keep your heavy equipment up and running. Our 145-8669: SWITCH ASSEMBLY are used on the joystick or control panel in order to connect or disconnect the circuits. They work in conjunction with the rest of your Cat electrical components, and they are designed to last. These Cat electronics are used in the steering system of Cat machines and can withstand extreme temperatures, dust, corrosion, vibrations, and more. Learn more at a Cat dealer near you today.
