| Size of pulley
Hi everyone
I bought a used Cooper S about a year ago and just recently had to change the drive belt on the engine and to my surprise the belt that came off was 20mm shorter than standard BMW belt. my question being does anyone know the diameter of the various pulleys std and aftermarket so i can check what is on my mini (diameter of the contact patch). Any help would be appreciated.
