What the COUPLING does
Couplings join rotating or hydraulic elements while accommodating the small misalignments a working machine always has. On a percussion drill they also have to survive the impact pulse travelling through the assembly.
Signs it needs replacing
- Backlash or lost motion between driving and driven halves
- Rubber or elastomeric elements cracked, crumbled or extruded
- Vibration and noise that rise with speed
- Fretting or wear debris around the coupling faces
Before you fit it
Check alignment when a coupling has failed. A coupling that wore quickly is usually reporting a misalignment that will consume the replacement at the same rate.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
