Beomaster 6000 (2702) restoration: broken FM dial wheel shaft bearing
When dismantling the Beomaster 6000 quad, I already noticed a damage to the ball bearing inside the shaft/bearing house of the FM dial wheel. The retainer clip was also missing and the 3mm nut was the wrong one. It needs to be a self locking nut. So time to start fixing this.
I guess the bearing got damaged while trying to remove or fix the (missing) retainer clip. It looks like someone pierced hard with a screwdriver on the metal shielding of the bearing. It turned out to be hard to remove the shaft as well due to some light damage to the end (where the retainer clip sits). Some force had to be used to tap it out.
The ball bearing is a SKF 625R type. The R stands for a low friction one sided metal dust shielding. The other side is open. That allows to put some (silicone) grease in it.
All is good! Another issue fixed. Up to the next one...
