Caterpillar parts

Caterpillar parts from Fab Heavy Parts cover aftermarket replacement components and service tools for selected excavators, loaders, compactors, and diesel engines. Find parts for routine maintenance, fuel-system repairs, engine rebuilding, and equipment controls, with compatibility specified in each product listing.

The collection includes fuel transfer pumps, fuel injectors, overhaul rebuild kits, filter kits, speed sensors, throttle motors, and cab blower motors. Engine service tools are also listed for tasks such as injector sleeve removal, injector height measurement, and engine barring. Selected applications include Caterpillar 3044C, C3.4, C3.3, and C3.3B engines, along with equipment models such as 311B, 312B, 259D, 289D, and 299D. These references apply to individual products, not the entire collection.

Match your original part number and check the machine model, engine model, and serial-number prefix before ordering. Compare electrical voltage, connector details, mounting configuration, and kit contents where provided. Filter selections and other components can vary between machines with the same model designation.
