Abstract
In the operation of a track chain assembly a high degree of wear is normally experienced due to the environment in which a track-type machine must operate. This wear is typically accelerated by foreign matter that is carried by an idler member of the track chain assembly and is permitted to remain on its contact surfaces as they engage the other track chain components. The present invention provides a scraper assembly that defines a plurality of scraping portions that are adapted to carry a scraping insert on an end portion thereof. The scraping inserts are continuously urged into engagement with the contact surfaces of the idler to remove foreign material therefrom before the contact surfaces engage other track chain components.
