What is a Radiator? A radiator is a type of heat exchanger used to transfer thermal energy from one medium to another for the purpose of cooling. It is typically found in the engine cooling system of vehicles and heavy machinery. For example, a CAT C15 Industrial Engine radiator is located at the front of the machine, where it can receive a constant flow of air. The hot coolant flows through the radiator's core, releasing heat into the surrounding air.

Small Talk about Machinery Maintenance: How often should I change the hydraulic oil filter on my excavator? The frequency of changing a hydraulic oil filter depends on the machine's usage and operating environment. A general recommendation is to follow the manufacturer's maintenance schedule, typically every 250 to 500 hours of operation. However, in dusty or harsh conditions, more frequent changes are advised to protect the system. Regular oil and filter changes are key for prolonging the life of your hydraulic parts .

Durable Transmission, Engine, and Electrical Parts

A machine's transmission system is what puts power to the ground. Our inventory includes crucial transmission components such as the Bevel Gear for the CAT 950GC Wheel Loader ( 512-1741 , 327-8692 ) and Friction Plates for CAT 793C Transmission ( 7T-2815 , 255-9267 ). We also provide Torque Converters and Drive Shafts , ensuring a smooth and powerful operation for your CAT machinery.

The engine system is the very core of your machine. We provide a full range of engine parts, from Cylinder Head Gaskets ( 4P-8915 ) to Exhaust Mufflers for various CAT engines ( 4916057 , 295-8200 ).

Small Talk about Machinery Maintenance: Why is my excavator's hydraulic cylinder moving slowly? Sluggish hydraulic cylinder movement can be caused by various issues, including low hydraulic fluid level, a clogged filter, a faulty relief valve, or a worn-out pump. If your CAT 374F Excavator Hydraulic Cylinder is slow, check the fluid level and filter first. If the issue persists, a professional diagnosis is recommended to check for pressure leaks or pump wear.

What is a Turbocharger? A turbocharger is a turbine-driven forced induction device that increases an internal combustion engine's power output by forcing extra air into the combustion chamber. For example, a CAT C13 Engine turbocharger significantly boosts engine efficiency and performance by compressing the intake air.

What is a Fan Drive? A fan drive is a component that transmits power from the engine to the cooling fan. It often uses a clutch mechanism to control the fan speed. For example, the fan drive on a CAT 336D Excavator ( 295-9439 , 137-3746 ) regulates the fan's speed to optimize engine cooling and fuel efficiency.

Small Talk about Machinery Maintenance: What does a track adjuster recoil spring do? A track adjuster recoil spring on a bulldozer, such as a CAT 349 Excavator , acts as a shock absorber for the track system. It maintains proper track tension and absorbs shocks from obstacles like rocks, preventing damage to the track and final drive components. A broken or weak spring can lead to track derailment and excessive wear on other components.
