Description:
Track bushings (part # 610-4677), along with the pins, hold the track links together and are part of the sealing arrangement between the link and the bushing.

Attributes:
• Stepped Wall Master Bushing for use with Grease Lubricated (GLT) systems.
• Stepped wall bushings have a larger diameter in the wear area to provide additional wear life.
• 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.
• Length: 164 mm (6.46 in)
• Wear Area Diameter: 70 mm (2.76 in)
• Inside Diameter: 47 mm (1.85 in)
