Caterpillar 239D3 Front Idler Details

Our Caterpillar 239D3 front idlers are designed to meet OEM specifications, ensuring reliable fit and performance. These dual flange tension idler assemblies feature durable double lip seals that prevent dirt and debris from entering while retaining lubrication for long-lasting operation.

The idler bolts directly to the tensioner or track adjuster to keep the rubber track properly tightened. If your track tensioner is fully extended and there’s still slack, a worn idler is likely the cause and should be replaced.

For optimal performance and a longer undercarriage lifespan, we recommend checking all undercarriage components during routine maintenance and replacing worn parts together.

At United Skid Tracks, we stock a full range of undercarriage parts for the Caterpillar 239D3, including  rubber tracks, sprockets, and bottom rollers—everything you need to keep your machine running smoothly.
