M5x Pulley Replacement for Older Mechanical Style Tensioner 11281427252

Over the years BMW switched from this older mechanical style tensioner to a hydraulic style tensioner.  The problem is, if the bearing in the pulley goes bad, you have to replace the whole tensioner unit/pulley which can be costly.  BMW does not sell just the replacement pulley, but we have found the exact size pulley replacement needed.  The mechanical tensioner is known to be a little more robust, as there is no hydraulic tensioner that can fail.  If your pulley is making noise, replace it at half the cost of replacing the entire tensioner.
