I JUST PURCHASED A NEW BALANCER AND BOLT FROM MBZ. I AM GOING TO REPLACE MINE NOW EVEN THOUGH IT LOOKS OK. THAT WAY I WON'T HAVE TO THINK ABOUT IT ANYMORE. DOES ANYONE HAVE ANY TIPS ON DOING THIS JOB, I NEED TO KNOW THE SIZE OF THE ALLEN BOLT, HOW TO HOLD THE PULLEY WHILE LOOSENING THE BOLT AND IF A PULLER IS NEEDED TO REMOVE THE BALANCER ONCE THE BOLT IS LOOSE. THANKS FOR THE HELP.
