529-8462: Master Track Pin

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 (529-8462) are installed in the master track link. Attributes: • Press Fit Master Track Pin • Length: 249 mm (9.8 in) • Diameter: 47.7 mm (1.88 in) • For use with Grease Lubricated Track (GLT), Positive Pin Retention (PPR2) systems. • 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. Application: Consult your owner's manual or contact your local Cat Dealer for more information.
