Service Questions with Louis: Component Inspections 

When it comes to keeping your rock crusher running at peak performance, component inspections are one of the most effective tools in your preventative maintenance arsenal. Regular inspections of critical parts like bearings, belts, liners, and rotors can help identify wear and tear long before it leads to costly downtime. These routine check-ups not only extend the lifespan of your crusher but also support safer operation and better production quality. By committing to thorough and timely inspections, you’re investing in the long-term reliability of your crushing operation.  

Check out Service Technician Louis’s list of recommended daily, weekly, and monthly inspections to add to your preventative maintenance routine. While this list is a good start, it’s important to review your owner’s manual for model specific inspection requirements. As always, remember to lock out and tag out your equipment before inspecting and working on it.
