Abstract

Disclosed is a fastening arrangement of a drive wheel member for an endless track of a tracked vehicle. The drive wheel member includes a hub member and a drive sprocket member, wherein the drive sprocket member includes a set of tooth members arranged around the circumference of the drive sprocket member. The drive sprocket member also includes a ring-shaped support member for tooth members of the drive sprocket member. The fastening arrangement is configured for fastening a tooth member of the set of tooth members to the support member so that the tooth member is in an operation position for engaging with the endless track, wherein the fastening arrangement includes an attachment device configured to detachably attach the tooth member to the support member such that the tooth member is detached from the operation position if the tooth member is subjected to a radial force exceeding a certain threshold.
