GOOD NIGHT I HAVE A SONY BRAND EQUIPMENT WHICH IS DENOTED AS FOLLOWS 60CD CHARGE MINI MHC-MG110 HIFI COMPONENT SYSTEM. THE PROBLEM IS THAT THE RUBBER THAT APPEARS WORKS WITH THE MECHANISM OF THIS. IS TO SAY THE CD IS REVENT. TO REMOVE IT MEANS THAT THE SAME CARRIES 2 MOTORS WITH ITS RESPECTIVE PULLEYS. WHAT I WOULD LIKE TO KNOW IS HOW I CAN KNOW ABOUT THESE BELTS AND HOW MANY IS THE ONE WHO IS IN CHARGE OF EXECUTING THIS FUNCTION THANKS AGAIN AGAINST YOUR ATTENTION AND YOUR HELP. A LOT OF SABER THANK YOU.
