Product Overview

The Front Idler Assembly, also known as Track Idler or Guide Wheel, is installed at the front section of crawler excavators.

Its main functions include:

• Guiding the track chain during machine operation
• Maintaining proper track alignment
• Supporting the track tension adjustment system
• Reducing abnormal track vibration
• Improving overall undercarriage durability

For a 36-ton class excavator such as LiuGong CLG936, the undercarriage system is exposed to continuous impact, heavy loading and abrasive working conditions.

A worn or damaged front idler may cause:

• Track chain deviation
• Uneven track wear
• Increased travel resistance
• Abnormal vibration
• Accelerated wear of track rollers and track chains

Our CLG936 front idlers are manufactured with professional undercarriage production technology, providing reliable replacement solutions for equipment dealers, contractors and repair workshops.
