Idler wheels guide and tension the track without transmitting power, while drive sprockets are powered components that propel the track through engagement with track links.
Inspect idler wheels every 250 operating hours for wear, bearing play, and seal integrity. Replace when flange wear exceeds 30% of original thickness or when bearings show excessive play.
Idler wheels with replaceable bearings and seals can often be rebuilt. However, wheels with significant wear on the running surface or structural damage typically require complete replacement.
