Abstract
In an aspect, a tensioner is provided for maintaining tension in an endless drive member in a belt-in-oil drive system. The tensioner includes a base that is mountable to a stationary structure and that has a circumferential wall that defines an arm pivot axis, an arm having a radially inner arm surface, and an endless drive member engagement surface that is engageable with an endless drive member, a bushing positioned between the radially inner arm surface and the circumferential wall of the base cup, and a tensioning spring. The arm is supported on the base cup via the bushing. The tensioning spring is positioned to bias the arm in a first direction about the arm pivot axis.
