Maintenance Points for Excavator Undercarriage Parts

During excavator operations, issues such as oil leakage from track rollers, damaged sprockets, weak mobility, and inconsistent track chain tightness often arise. These problems directly affect the excavator's performance and mobility.

Origin Machinery provides tips to extend the service life of undercarriage parts:

 1. Track Roller

1Avoid Soaking:

To prevent prolonged immersion in mud, prop up the single-sided crawler chassis after daily work. Utilize the walking motor to shake off dirt and debris from the track.

2Keep Dry:

 In winter construction, ensure the rollers remain dry to prevent damage to the floating seal. Water freezing overnight can lead to seal damage and subsequent oil leakage.

 2. Carrier Roller

1Prevent Damage:

The carrier roller, crucial for maintaining track alignment, should be protected from damage.

2Keep Clean and Dry:

Minimize immersion in mud to prevent lubricating oil leakage. Regularly clean the X-frame inclined platform to avoid hindering carrier roller rotation with accumulated debris.

 3. Idler

The idler, positioned in front of the X-frame, maintains chain alignment during operation. Keep it ahead during operation to prevent abnormal chain wear. The tension spring absorbs surface impact, reducing wear.

 4. Sprocket

1Positioning:

Mount the sprocket behind the X-frame to prevent abnormal wear and potential frame damage.

2Regular Cleaning:

Clean the traveling motor guard regularly to prevent soil and gravel accumulation, which can wear internal components and corrode joints.

 5. Track Assembly

1Gravel Removal:

Regularly clear gravel from the track assembly, particularly in mines where wear is most severe. Gravel lodged between track plates can cause bending and deformation.

2Tension Adjustment:

Avoid excessive tensioning of the link assembly to prevent premature wear of track components. Adjust tension based on construction road conditions.

Implementing these maintenance practices will optimize excavator performance and extend the lifespan of undercarriage parts.
