Excavator Undercarriage Parts & Components

Common excavator undercarriage parts include the track group, shoes or pads, bottom and carrier rollers, front idlers, sprockets, track adjusters, recoil assemblies, guards and mounting hardware. McCann can supply individual components or evaluate a matched replacement package. Provide the machine make, model and serial number so the correct configuration and component fit can be checked.

Component-by-component replacement can address wear where only selected parts have reached their OEM limits. When overall wear is high, a matched package may provide better value because new chains, sprockets, rollers or shoes can wear quickly against heavily worn adjoining components. McCann can compare a targeted repair with a broader replacement recommendation after measuring the machine.

Yes. McCann supplies OEM components through its CASE Construction Equipment, KOBELCO and Takeuchi dealer channels, along with quality aftermarket options. Service is also available for all makes including CAT, Deere, Komatsu, Bobcat and Kubota. Ask for both options with expected life and applicable warranty terms stated in writing before making a purchase.

Start with the machine make, model and serial number, then identify the track type and the component requiring attention. Wear should be assessed against the manufacturer's model-specific limits, including chain, bushing, pin, roller, idler, sprocket and grouser condition. McCann can help distinguish a targeted component replacement from a full matched undercarriage package.

McCann states that in-shop and in-field assembly installation are available. Field installation can help avoid transporting the machine for heavy undercarriage work. The machine must be properly supported and stored energy controlled, especially around the pressurised track adjuster and recoil assembly. Confirm installation scope, labour pricing and scheduling when requesting the quote.

Inspect the undercarriage on a schedule appropriate to the machine's duty cycle and working conditions, and measure wear against the OEM specifications. Maintain correct track tension, avoid unnecessary high-speed travel and excessive turning, and address worn sprockets, rollers, idlers or chains before failures damage adjacent components. Abrasive material, frequent travel and side-slope work can accelerate wear.

McCann carries excavators from three lines. CASE Construction Equipment covers excavators and mini excavators. KOBELCO covers mini excavators, conventional excavators, short-rear-swing excavators, and specialty excavators for long-reach, demolition, and material-handling applications. Takeuchi covers mini excavators. Parts and service for other makes, including CAT, Deere, Komatsu, Bobcat and Kubota, run through the same counter.
