How to change motor in Arri Arriflex 16BL film camera

Old and heavly used Arri 16BL 16mm film camera can have many issues. In our case motor (EMP) was faulty. It always went straight to 50 fps. No matter what combination of bridging in power plug was done. Only replacement NOS motor (BLE) fixed the problem. Wonder what type of motor sits in your Arri?
