Terex SKSS-13 Infinity Blasthole Drill Service Manual (91-A11-374)

The Terex SKSS-13 Infinity Blasthole Drill is engineered for deep, precise drilling in demanding mining environments. This Service Manual dives into rotary head mechanics, air system routing, hydraulic feed cylinder behavior, and structural stress points that often show early wear. Its diagrams help technicians visualize how each subsystem interacts under load, especially during continuous drilling cycles.

Applications & Use Cases

Diagnosing rotary head vibration or torque loss
Servicing feed cylinders, air compressors, and drive motors
Tracking hydraulic pressure irregularities
Preparing the drill for sustained high-depth drilling operations
Identifying worn bushings, bearings, and seals

FAQ
Does the manual include air and hydraulic schematics?
Yes, complete layouts with flow direction markers.

Is it helpful for heavy mining operations?
Definitely. It covers common fault patterns seen in long drilling shifts.

Safety Note
Lock out the air system before opening any compressor or feed components.
