The Caterpillar 173-0946 Sprocket Segment (Sprocket Tooth) is a genuine OEM-specification undercarriage component designed for Caterpillar D6R and D6T series dozers. This sprocket segment is part of a segmented sprocket design, where multiple segments bolt together to form the complete drive sprocket ring.
The segmented sprocket design allows for individual replacement of worn segments rather than replacing the entire sprocket, significantly reducing maintenance costs and downtime. Each segment features precision-machined tooth profiles for optimal engagement with the track chain.

Note: This is a sprocket segment for Caterpillar D6R and D6T series dozers. Multiple segments are required to form the complete sprocket ring - consult your parts manual for the exact quantity per sprocket. The segmented design allows for cost-effective individual segment replacement. Verify machine serial number and undercarriage configuration before ordering.
