STEPS TO KEEP YOUR MACK DIFFERENTIAL RUNNING SMOOTHLY

Preventative Maintenance

Preventive maintenance includes many techniques—like correctly selecting and changing drive train oil and fluid filters—that help you keep small problems from becoming major repairs.

S-O-S Fluid Analysis

This is the best way for you to monitor what is happening inside your drivetrain systems. It consists of tests that enable you to forecast wear-related problems.

Inspections

Inspections combine your daily walkaround checks and our periodic technical analyses. They allow you to detect potential problems and impending failures so you can schedule maintenance and repairs.

Repair Management

Repair management helps you select before failure and after-failure repair options and control repair costs. It allows you to plan and schedule repairs, so you can get your machines back to work quickly and reliably.

Scheduling

A good scheduling system ensures that maintenance, inspections, and planned repairs are done on time. It helps you prevent the failures caused by overlooked maintenance.
