| UPDATED Clamp Master Links for | |||||
| SystemOne Undercarriage | |||||
| A new Clamp Master Link is available for the following specific machine models: | |||||
| Low Sprocket Tractors D3C/G/K, D4C/G/K, D5K, D6K | |||||
| 953, 963 | |||||
| Elevated Sprocket D6H/R/T, D6M/N | |||||
| The new clamp master links incorporate a center strut for improved strength and rigidity. The ability to easily remove the track is a key feature of the clamp master link on SystemOne UC. The clamp master can be taken apart by removing the bolts from the master link instead of requiring tooling to press the link on or off. The master link retains the same unique SystemOne ?straight? link design and provides unmatched reliability and durability of SystemOne Undercarriage. | |||||
