Hi my beomaster 6000 has a problem withe the volume it struggles to push up to 30 and just a running motor noise. had a look inside and I think the belt is slipping??

Any suggestions?? Can I get a new belt form the belt man...... martin?? 

Thanks

Common fault.
The belt may be worn but in most cases a gentle lubrication of the volume potentiometer will work wonders.
I generally advice against the use of contact cleaner unless there's a chance to clean it off afterwards
but in this case, where it's hard to get inside the potentiometer and sewing machine oil can't be found
as an aerosole spray, I would use the type of contact cleaner spray that has an amount of lubricant built-in.

You can clean the belt to further improve matters using isopropanol.

Thanks Martin

which bit is the potentiometer? Also is the contact cleaner wd40 and where would you sprayit?? I do have sewing machine oil.

Thanks 

Andy,

The potentiometer sits at the underside of the top part when in service position.
It is motordriven through a belt and a gearbox which also pulls
the screen for the volume readout using a dial string.
Quite an arrangement.

With all due respect Andy, and don't get me wrong, if you can't locate
the potentiometer, this may not be a task for you.

WD40 is good for losening rusty bolts in a car, it contains
lubricants but also acid in some form and probably other chemicals
that don't evaporate completely and which use we do not need.
We don't want that anywhere in our homes, especially not in our B&O.

For this task we need "real" contact cleaner with a hint of acid-free
oil in it.
Kontakt Chemie makes the "Kontakt 61" which is what I normally use,
though this is an exception from my normal practice.
Contact cleaner does not remove anything by itself, it merely losens and shifts the dirt and oxidation around and in the best
case it evaporates completely without adding to the mess. Clean and dry is good.

Normally, I would take the things completely apart, clean everything using contact cleaner or similar, wipe dry, lubricate sparringly any seize- or wear-prone parts and put back together. In this case though, the potentiometer is quite hard to access or even remove from the Beomaster and hard to take apart afterwards, besides it doesn't make much difference doing so. Do cover up the belt drive and dial string if you intent to spray to prevent excess slippage.

Thanks Martin

I wouldnt take it the wrong way. I have located it but didnt know if it was the motor bit on the right as you face it or the bit that pulls the volume strip on the left. Your right I wouldnt know what or where to spray so best left otherwise It might become completely stuck.

Thanks again help as always much appreciated

Hi I had the same problem with mine, I opened it up, as you have done, slipped the belt off (which as you may know you cant remove it completely) and carefuly cleaned the belt and the pullies with a damp cloth with some very mild fairy liquid on it. This worked for me, when I say very mild fairy, I mean a couple of drops in a full basin of warm water. Oh and I let it all dry before I put the belt back on

Hope this helps

Graeme

Thanks

have done all that and then roughened it with a light sandpaper. Works really well now

Thanks for all your help!!
