A skid steer loader having transversely spaced wheel assemblies driven through a drive chain entrained around a tensioning idler is disclosed wherein the tensioning idler is mounted in a pair of arms movably positionable by an adjusting mechanism to control the tension in the drive chain. The adjusting mechanism is housed within a box welded to the chain case and includes a necked down portion extending through the box for external manipulation of a drive portion. An O-ring seal prevents the loss of fluid from the box during operation of the loader. A spring clip engagable with the drive portion of the adjusting mechanism prevents the movement thereof during operation of the loader.
