576-4689: Track Link Assembly (GLT)

Description: 576-4689 is a grease lubricated track link assembly. Link assemblies, driven by sprocket and final drive, provide support to the machine weight, a rail for the machine to run on, and a place for the shoes to attach. Attributes: • Grease Lubricated Track (GLT) Link Assembly • Track Pitch: 190 mm (7.5 in) • Number of Track Sections: 49 • Grease Lubricated Track features internally greased pins and bushings to eliminate contact and friction, each track joint sealed to retain the grease. This improves internal wear life by 25% over sealed track, decreases undercarriage noise and reduces the potential of frozen or seized joints.
