Does this consider the CB or the FL head ?
Just installed mine, an SD5. From the Sanden FAQ: https://sandenaftermarket.com/about-sanden/sanden-faq/#:~:text=Sanden%20standard%20compressors%20rotate%20in,contact%20your%20official%20Sanden%20representative. Sanden standard compressors rotate in a clockwise direction only with the exception of SD5 Sanden models that can run in both clockwise and counter clockwise direction. For further information, please contact your official Sanden representative.
