BMW N47 tool for removal of the balance shafts, from the gears. This tool will help you to remove the balance shafts from the cylinder block of the engine.

Replacement of the OEM BMW tool : 11 8 870. Pretty much the same tool, but from normal steel. We are using it in our shop for several years without any issues, so we have decided to start selling it, because the OEM tool is quite expensive for what it is.
