Service Magazine SEPD1506, 3 October 2012, "A New Front Track Idler Arm Is Now Available on Certain Asphalt Pavers". Disregard this article. Use the following article.

Description of Change: A longer idler wheel arm 366-8397 is now available. This component will allow for longer track and under carriage life by allowing for more track wear. The lower arm adds additional range for the tension cylinder to account for more undercarriage wear.

Adaptable To: 366-8397 Arm will replace the 179-6983 Arm .
