Can someone help please?

I've got a 1985 Japanese made BB1100S and one of the tuners has an issue. As I turn the D string tuner to slacken off the string, rather the string coming slack, the tuning is unscrewing itself and the knob with worm gear is coming out of the tuner back plate. Is there anyting I can do to fix it?

I really don't want to replace the tuners, they've got an amazing look to them from over 40 years of use although that 40 years of use may be the problem!

 

Are they these guys?
