The Epiroc 2657467151 Sprocket (Drive Sprocket) is a genuine OEM-specification undercarriage component designed for the Epiroc DMM3 drilling rig (formerly Atlas Copco DMM3). This sprocket is a critical drivetrain component that engages with the track bushings to propel the machine.
The DMM3 is a versatile drilling rig used in underground mining for production drilling, bolting, and ground support applications. This sprocket features precision-machined tooth profiles for optimal engagement with the track chain, ensuring efficient power transfer from the final drive to the undercarriage. The 34-bolt mounting pattern provides secure attachment to the final drive.
