Hi all,

Recently I found a set of 3 BeoSystem 5000 units at my local thrift store (€15,00 😁)

It consists of the Beocord 5000 (Type 4921), the Beomaster and the Beogram CD-50 plus the Master Control Panel.

The Beocord needs new belts as it does not open by itself. Are there dimensions known of these belts?

If I search the net, I find it somewhat confusing, mostly I find a set consisting of 3 belts.

Are these all belts or is this just for the cassette drive mech itself and not for the drawer?

Does anyone have the dimensions of these belts and, is this belt set also used in other units by B&O?

 

The CD-50 does open and close but does not play a disc, it makes a rattling sound. Maybe the laser unit that is stuck

Correct belts can be found here - both the 3-belt set for the tapedrive and the belt for the drawer.
(Plus many other parts).

B&O never disclosed specs like dimensions/friction/elasticity.
But they are not standard belts, and you can forget the junk sold at Ebay, if you have your motor bearings etc. dear.

As Martin says, you don’t need any dimensions, just the correct belts.

Ebay sellers sell generic junk you don’t want to buy, believe us. Too tight and you’ll ruin the precious motor, too long and the deck will wow like hell. Rubber quality also matters. Useless.

Beoparts will sell you specially and carefully remanufatured belts to specs.

I had a look there (at the B&O shop), and surprisingly it is not to expensive to ship to my country. So I will order them there I guess. But I only seem to find the 3 belt set if I type the beocord 5000 in there. The drawer belt I cannot find.

BTW, you only assumed I wanted to buy at ebay, that was never the case. I wanted to buy at my local vendor that has belts but hasn't got the specs of these. So I guess either those are generic ones or he does not know which ones I mean.

Normally buying outside of your country is much more in shipping than if I buy something local. That is why I wanted the measurements.

Your local vendor will not have the correct belts anyways.
He may be able to match the sizes - sort of -, but the elasticity is what kills most drives.

The drawer belt is BS-018.

Thanks :) !

I could find that one.

In cas of the CD-50 making a rattle noise when reading a disc (inserted the right way), do you think it is some part that needs

replacing also? If so, maybe I can order that along with the rest.

Difficult to diagnose from a distance. It could be many things, but most likely not as simple as a part in need of replacing.
- Bad height adjustment of the hub.
- Dry spindle motor bearings.
- Dry tracking mech/gear.
- Any combination of the above or something completely different.

Does it spin the disc?
Does it show the numbers of the tracks?

Not sure if it spins the disc, I will open it to see if it does.

Numbers are not shown.

 

Yesterday I took a video of what happens:
