Just got off the phone with Aisin tech support. They are introducing a new kit for the Outback/Legacy platform which uses curvilinear timing belts. It is the TKF 011. Their current kit is TKF 006 for Forester/Impreza with modified curvilinear belts. You can look at a couple recent threads I started on this kit. Except for the belt, all other parts are the same. Aisin said the same thing Gates did - the same grooved idler works on both belts. In fact, Aisin will use the same grooved idler in both kits and refer to it as OEM 13085AA080. Subaru says the idler for curvilinear belts should be 13085AA061. I had both in my hands and they are identical except the 080 has two bearings. So, my earlier recommendation is validated. Use the 006 kit and buy the right timing belt or wait a couple weeks for the new TKF 011 kit to hit the stores.
