Let’s learn how to maintain your Cat® 120 motor grader. Proper, regular maintenance is crucial for optimizing performance and extending the life and usability of your machine. The following video will take you through some of the most important points of motor grader maintenance.

How to Maintain your Cat 120 Motor Grader

Before getting started, remember to always refer to your Operation and Maintenance Manual for guidance on maintenance, safety, settings, feature and more. Check your motor grader’s fluids regularly and replace them according to your motor grader’s recommended change intervals. Make sure your fluid filters and air filters are checked often and replaced as needed; you will find these grouped together on your machine for easy access. Inspect your work tool and tires for cracks, wear and damage, and inspect your powertrain daily, making sure that it’s clear of debris. Check for leaks and loose segment bolts. And practice all recommended safe operating procedures.

Cat 120 motor graders deliver fuel efficiency and easy maintenance features that reduce owning and operating costs. The articulation hitch gives you more maneuverability with a shorter turning radius. The standard drawbar circle moldboard with hardened circle teeth is built to last, giving you precision pass after pass. For tight finish grading, consider the top adjust drawbar option for applications that require maximum accuracy. It offers up to 45% reduction in maintenance costs over the standard. And the Circle Saver option can reduce your daily greasing requirements and save you repairs to your circle and pinion.
