Servus mitnander,

ich suche (fast schon verzweifelt) jemanden unter euch, der mir behilflich sein kann, meinen `68er Beogram 100 V wieder flott zu kriegen.

Diagnose:
Der Motor brummt nach dem Einschalten.
Der Teller dreht sich nicht automatisch mit, lässt sich aber von Hand ohne weiters bewegen.

Indikation:
Noch keine, da ich nicht weiß, was zu tun ist.

Therapie:
Eure Hilfe ...!?

Vielen Dank für eure Mühe, schöne Grüße aus dem Allgäu,
Christian

Christian,

Many, many, many years ago these motors started giving problems in the Beogram-1000.
I didn't think any had survived this long. Not without some repair at least.
What I remember is, that the motor should be taken out and disassembled completely. The bearings are stuck in hardened grease and should be cleaned with iso propyl-alcohol. Then oiled (oil to be used with sewing-machines is fine) and re-assembled. To center the bearings when re-assembling, just tap the motor gently with the shaft of a big screw-driver. You will feel the rotor moving more and more freely with each tap.
Tighten screws fully and put the motor back in.
Usually it works well, BUT... I HAVE seen the motor getting stuck again within a short time. It can be extremely hard to clean the bearings completely at the first try. If this happens you will have to start over again.

Good luck,

mfg,
