Service Questions with Louis: Parts that Require Regular Replacement

Heavy equipment is the backbone of industries like construction, agriculture, and mining. These machines, such as rock crushing equipment, take on demanding tasks daily, making their reliability crucial for productivity and safety. However, without regular maintenance, even the most robust equipment can break down unexpectedly, leading to costly repairs, project delays, and safety hazards. Implementing a consistent maintenance routine ensures that your heavy machinery operates efficiently, extends its lifespan, and minimizes downtime—ultimately saving your business time and money.

Top Five Parts That Require Frequent Replacements

It’s recommended that you inspect every part of your equipment prior to use. If any wear parts, such as the following, or any other part of the equipment is broken, bent, cracked, or otherwise not to standard, it’s recommended that you replace it before operating.

• Wear Liners
  • Replace wear liners when liners are worn down to ¼ inch thick
  • This also applies to secondary curtain liners

• Impactor Primary Curtains
  • Primary curtains are typically two sided and should be flipped when worn down to 1 inch from the mounting ear

• Blow Bars
  • Blow Bars can be worn down to 7/8 of an inch before flipping them the first time.
    • 
  • The second side can be worn down to ¼ inch before bars need to be replaced
  • Always replace cracked or broken blow bars

• Jaw Dies
  • Jaw Dies are one sided and can be flipped from top to bottom
  • Worn down, or smooth, jaw dies may not properly grip and crush the rock to the size required so it’s best to flip them before that happens.

• Screen Cloth
  • Screen cloths can be manufactured from a variety of materials, like wire cloth
  • Always refer to the screen cloth manufacturer’s guide for replacement

Making Regular Maintenance Part of Your Day

A proactive approach to inspections, servicing, and repairs helps prevent major failures, reduces operational costs, and maximizes productivity. Whether it’s checking fluids, replacing worn-out parts, or following manufacturer recommendations, staying on top of maintenance ensures that your equipment remains a reliable asset rather than an expensive liability.
