John Deere 17D Tension Idler Assembly

Aftermarket Replacement | Part #9312918

This aftermarket tension idler assembly is built for the John Deere 17D mini excavator and arrives fully assembled and ready to install on your machine’s tensioner. The tensioner spring is not included and must be reused or purchased separately.

This idler replaces  9203517, 9312919, 9312918 and comes equipped with the correct bushing and brackets for a precise, direct-fit installation.

Built to original specifications, these single-flange idler assemblies use high-quality double-lip seals that keep dirt and debris out while locking lubrication in to extend component life. The yokes are designed to fit perfectly into your track frame, making installation fast, clean, and reliable.
