Description:
Track pins, along with the bushings, hold the track links together. The pin acts as a hinge at an adjoining bushing. Master track pins are installed in the master track link.

Attributes:
• 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.
• Positive Pin Retention (PPR) track has a metal retaining ring pressed into the groove between the pin and the link. This prevents end-play generation and helps ensure oil retention in high impact applications for excavators.
