Routine maintenance of your production loaders helps ensure high productivity, keeps operating costs down, and promotes long machine life.

Production loaders set the pace for putting rock in the box. Keeping them digging and loading efficiently is largely a function of routine maintenance. Proper routine maintenance, coupled with good operating practices, delivers the lowest cost per ton.

Production loaders, which set the pace for putting rocks in the box, need to be maintained properly to ensure lowest cost per ton.

Following the inspection guidelines and maintenance intervals detailed in your wheel loader operation and maintenance manual is the best way to keep operating costs down, and it’s the main way to avoid mechanical failures that result in costly unplanned downtime and lost production. Additionally, routine inspection and maintenance — with emphasis on repair before failure — enable components to achieve their full design lives. Worn components taken out of service before they fail also have a greater likelihood of providing valuable cores for remanufacturing.   

Routine maintenance is a shared responsibility of maintenance technicians and wheel loader operators. The pre-shift truck inspection conducted by the operator is both a safety inspection and a maintenance inspection. Ideally, the operator will use a checklist for the walk around inspection. Figure 1 is an example checklist for wheel loaders. Additional information about conducting a wheel loader walkaround inspection can be viewed on the Caterpillar Web site: safety.cat.com.

The problems that the operator detects and reports during the walkaround inspection and during the operating shift often can avert costly mechanical failures. Regardless of who is conducting inspections, monitoring machine health, or performing routine maintenance, the operation and maintenance (O&M) manual for your wheel loader provides details that can guide those actions. When you have questions, refer to the O&M manual first for answers.

Here’s an overview of maintenance recommendations for key systems.
