Help Prevent Costly Repairs With Heavy Equipment Maintenance Checklists
In construction or any industry where heavy equipment is used, time is money. Heavy equipment breakdowns can significantly slow down or even bring a project to a standstill, impacting productivity, deadlines and potentially incurring financial penalties.
The costs of unplanned downtime can quickly add up when you consider the need for fast repairs of failed components and any related damage, rental replacement equipment and potential delays of materials.
What’s the best way to avoid unexpected repairs and downtime?
Prioritize early detection of equipment warning signs before they spread. Use a checklist to make sure you don't forget to check in on any systems or parts. Note unusual sounds or subtle changes such as paint discoloration. Minor issues like these can be hard to spot. But with the right knowledge, you can often stop them before they lead to major repairs.
Taking a proactive heavy equipment maintenance approach can:
Reduce operating costs per hour
Enhance safe operation
Protect your warranties
Extend component and equipment life
Stabilize schedules
Increase uptime and productivity
Help you identify preventive actions you can take
Preventive machine health monitoring not only saves money but also helps ensure a successful job. Key parts of a proactive heavy equipment maintenance plan should include:
Regular inspections using the Operation and Maintenance Manual (OMM) for your equipment as a guide
Cat® inspection apps
Awareness of any other issues that could impact equipment failures
Knowing when to consult your local Cat dealer
Inspections take time. How can I make them fast and effective?
The best way to make inspections fast and accurate is to use checklists and tools. Daily walkaround inspections are recommended. You or your Cat dealer should train operators to keep them up to date on their machines. Download safety checklists for walkaround inspections and startup and shutdown procedures here.
Caterpillar also offers Cat Inspect, an easy-to-use application which allows you to download and complete predefined inspection tasks on your phone, laptop or tablet. You can include pictures, comments and ratings for your Cat equipment and other OEM equipment.
The Cat Inspect web portal allows you to retrieve completed inspections so that you can quickly view changes over time.
Inspection forms include:
Preventive maintenance checklists
Technical analysis forms (TA-1)
Daily safety walkarounds and more
With the ability to create custom forms, you can document exactly what you need to. Contact your local Cat dealer for initial setup and support.
You can also order planned maintenance kits that have everything you need for correct filter and fluid replacements.
Symptoms That Could Indicate A Problem
In general, you should note any condition that is unusual or a sign of damage such as cracks, dents, dirt or fluid buildup as well as sounds or noises that are not normal. Consult your equipment’s OMM before taking any action or making repairs.
This guide provides an overview of engine, hydraulic, electrical and undercarriage symptoms. You'll also see possible causes and actions you can take.
Here’s one scenario you might encounter. Grinding or clicking when turning the ignition key, could be caused by:
Worn starter motor
Damaged flywheel
Misaligned gears
Magnetic clutch failure
Low battery voltage
The repair indicator inspection guide outlines what to look at and what to look for. With that information, you can narrow down the culprit. In this case, you’re probably facing a battery, starter or flywheel replacement.
Be sure to address all indicators as soon as possible to prevent larger issues.
If You Do the Repairs Yourself, Does It Void The Warranty?
Your warranty is very important to ensuring the value of your equipment. A Caterpillar equipment warranty may be voided for a number of reasons.
Specific coverage details and terms vary by product type, application and location. Contact your authorized Cat dealer for coverage details, including the applicable Caterpillar Limited Warranty.
And follow the recommendations for maintenance and specifications for filters, fluids and parts to maintain your equipment and its warranty.
One additional means of protection is an Equipment Protection Plan (EPP) for a new, used or rebuilt machine. An EPP:
Provides coverage beyond standard machine warranty for parts and labor, and protects you from unplanned repair costs from covered defects in Cat material and manufacturer workmanship
Offers multiple coverage options to fit your needs and budget
Includes genuine Cat parts and service performed by factory-trained dealer technicians
Transfers with the machine when you sell it in the same region the EPP was purchased
If you have questions about the right repair or diagnostic kits for your job, get in touch with your Cat dealer. They can provide expert guidance tailored to your specific needs.
