Note:
This idler assembly is a critical undercarriage component for Caterpillar D11 series dozers, designed to guide the track chain and maintain proper track tension.
Compatible with HDXL, GD, and HD undercarriage systems, providing flexibility for various track configurations.
Features precision-machined bearing surfaces with hardened tread for maximum wear resistance in severe dozing applications.
The 13.307-inch (338 mm) rim width accommodates wide track shoes for excellent flotation and stability.
Due to its extreme weight (857 kg), specialized heavy lifting equipment and strict installation procedures are mandatory.
Please verify exact compatibility with your specific machine serial number and undercarriage configuration before installation.
If you need specification sheets for other undercarriage components (track rollers, carrier rollers, sprockets, track shoes), please feel free to let us know.
