Speedometer main shaft vibration
 

Hello,

I am wondering if someone has found a solution for the problem I am facing.

I have a 71 speedometer, with the cable to my 901 gearbox.

The cable connect in the speedometer to a shaft which has a sort of magnet flying-wheel on the other side.

The problem is that the shaft sometimes vibrate. There is a very little play, like if the shaft is too loose in his housing. There is a screw to press the flying-wheel against the main body but it doesn't help.

Did anyone encounter the problem ? Any idea how to solve it ? Any kind of bushing solution ?
