Abstract: An automatic mechanical tensioner assembly with a shipping and installation position in which a collar engages a fixed hollow sleeve, limiting or securing a moveable tensioner housing in place against the force of a spring. The collar has a semicircular body defining an inner circumference extending from a first end to a second end of the body. The semicircular body has two axially extending flanges defining a cutout, and a collar tab extending radially from the semicircular body. In the shipping and installation position, the first end of the collar engages with a delivery groove of the hollow sleeve, biasing the moveable housing towards an anti-rotation washer engaged with an end of the fixed hollow sleeve and compressing the spring.
