Good afternoon
my beocenter 9500 is workung fine, just the tape drive is out of service! the center is open , the tape drive is disassembled : reason for the malfunction : the big flat belt is distroyed!
I do have the new 3 belts allready but I do not know the routing of the large belt . how is the routing of the belt ? does somebody can explain to me?
I think for me its clear: around the white little weel , wich is fixed on the removed ironed bridge wich is fixed over the two alu big wheels, then arround the black plastik wheel . but now how arround the alu wheels?
What starting position does this two wheels have ( there are two signes on the surface, (maybe this signes are just holes to make the alu wheels balanced).
Thanks for any help, regards ueli
If the big wheels are viewed side by side with the rest of the mechanism above, then the belt goes all the way around the big wheel on the left, and then loops under the one on the right, with the outside of the belt going around the little wheel in the corner and then stretching up to the drive wheel.
Perhaps you could post a photo and I could draw it on?
Thanks for your reply . Aside of the picture is the driving wheel , fixed on the iron bridge wich will be fixed over the two alu wheel.
thanks for your help
Best regards ueli
Ask the seller for mounting instructions.

Yours looks different to mine, but then I know that there are two versions.
If you look at this thread: https://archivedforum2.beoworld.org/forums/t/18104.aspx
There is a photo showing the routing for my type which is similar - can you work it out from that?
Cancel my last!
Have a look at this video which shows a belt change on a BC2500. The tape deck on your 9500 is very similar, except that your motor is mounted in a different place and feeds the system via an additional belt.
I think you will be able to work it out from this: https://www.youtube.com/watch?v=JnAD5PbyBGA
By the way, I found the video linked from this thread: https://archivedforum2.beoworld.org/forums/p/26380/210508.aspx#210508
(And as an aside, Martin (who posted about asking the belt supplier) sells belt replacement kits and always includes excellent fitting instructions! This explains his reticence to help out the competition!)

Competition is healthy.Having said that, I make next to no profit on the belts I provide so I really don't have to sell any.The far majority of my belts are from my own production because most of the cheap standard belts generally available on Ebay etc. areuseless in B&O.I need quite a few belts (and other else-unavailable parts) for my own repairs and restorations so I have to make some myself.
Producing molds, having chemical analysis done, casting, testing etc. is both very costly and timeconsuming.For most of the parts I provide I will never reach the point of break-even.And I also spend time making instructions.
So competition doesn't bother me. What bothers me is all the damage done to nice vintage B&O decks caused by wrong belts.I've seen no less than five different size belts sold for the same deck - by the same seller. None of them correct, andeven if the size was close to being correct, the elasticity was far off.I've even seen drain- or sewer pipe gaskets (!) sold on Ebay as belts for Beogram 1000 etc. They were about the right size but stiff asplastic and of course absolutely useless.Not a single day goes by without one or more emails or Ebay messages from frustrated belt buyers.Some of them stopped when things didn't look or feel right - but unfortunately not all.I do my best to help out where I can. That often begins with sending them the correct parts - and sometimes alsoreplacement parts to take care of whatever collateral damage was caused.
So please don't get me wrong. I help a lot of people every single day. Parts, advice, diagnoses etc.More than a few times did I send my belt mounting instructions to people whobought belts from Portugal or wherever, and several times was I blamed when motor bearings got damaged and the motorstarted screeching after just a few playing hours, when electronics burned etc. etc. etc.I've heard it all enough times to only supply my instructions to people who bought my belts.
But yes, there are two very different deck types. OP has the later type and it's somewhat identical to thedeck used in Beosystem 2500 as Guy mentions.Don't be surprised if something doesn't seem to fit or if the motor makes more noise or draws more currentthan normal. Blame that on the belts and stop using the deck asap. I'm running out of spare motors.
Hallo Martin
Besten Dank für Deine Antwort. Vor einigen Tagen stand ich mit meinem Beocenter am Abgrund (sprich verschrotten) , nun bin ich einen Schritt weiter....
Ich verstehe Deine Argumente sehr gut , ein solches Gerät in der Schweiz reparieren zu lassen, übersteigt sehr oft den Realwert eines Gerätes (wegen sehr hohen Fachmannkosten, sehr oft kostet schon nur der Gedanke, einen Schraubendreher in die Hand zu nehmen).
Also versucht man es selber, sucht nach Ersatzteilen in der Bucht und bestellt dei dem, der so etwas anbietet und ist froh , etwas gefunden zu haben. Im Nachhinein ist man immer wieder etwas schlauer).
Nun drehen die Räder wieder, solange alles richt eingestellt ist , d.h. in die richtige Position geschaltet ist , wechsle ich die Spielrichtung (Tonkopf ausfahren, drehen, einfahren ), bleibt alles stecken und ein Schleifgeräusch ist zu hören.Drehe ich nun mit dem Finger am rechten Schwungrad (etwa eine viertel Drehung ) verschwindet das Geräusch und das Tonband funktioniert wieder. Gleicher Vorgang passiert, wenn ich von Vorspulen auf Rückspulen schalte. Meine Diagnose: sobald der Widerstand auf den Antriebsriemen ansteigt , dreht die Antriebswelle weiss , durch und generiert das Schleiffgeräusch , weil die Haftung/Andruck Riemen zu klein ist.
Folgerung: ich möchte zwei (2)Stück Deiner Flachriemen/Antriebsriemen bestellen . Wie kann ich bezahlen , wie lieferst Du. Postfach in Weil am Rhein vorahnden, Paypal ebenso. Sonst Lieferung per Post in die Schweiz.
Danke und Gruss Ueli

Hallo Ueli ,
ein recht typischer Fall von " Schrottriemen " , das hast du schon richtig analysiert .
Der Grip , sprich die Vorspannung des Capstanriemens ist bei diesem Laufwerk
extrem wichtig , ist er zu lasch , bekommst du Fehlfunktionen sowohl beim
Abspielen , bei der Reversefunktion und auch beim Spulen vorwärts und
rückwärts .
Bei der Gelegenheit des Wechselns des Riemens solltest du auch
unbedingt das Kurvenrad kontrollieren und gut schmieren , auch die
Leichtgängigkeit der Magnetspulenanker überprüfen .
Die Vorspannung des Riemens in Zusammenarbeit mit den
Magnetspulen sorgt für das richtige Abtasten bzw. Abfahren des
Kurvenrades , welches die verschiedenen Laufwerksfunktionen
auslöst .
wünsche viel Erfolg ( ist alles kein Hexenwerk ! )

Hello Martin,
I'd like to buy a set of belts with instructions for my recently acquired BC9500, the tape unit is the second version I think.
