Hey all,
New user here. I've owned a Beogram 1602 for some time, and recently snagged a Beomaster 6000 and Beocord 8004 from a law office that was tossing them due to a nonadjustable volume stuck at 60%. None of the volume presets work either, but I was able to trace the issue to the volume servo motor, which is receiving voltage in correspondence with button input but is not engaging. I'm able to adjust the volume by disengaging the belt from the servo pulley and turning the potentiometer. The gearbox appears to be spinning as it should, but the motor feels awfully stiff. I want to strip it down and check it out, but the motor module itseld seems stamped shut or something. Can't figure out how to open it without damaging it, and I am having no luck finding a replacement part online. Anyone rebuilt one of these little motors or who can point me in the right direction for a replacement? I love how the unit sounds, looks, feels, and everything else seems to function 100% as well as on the Beocord. Any advice is great, and I can share photos if that is helpful
Thanks!
er,is it a silly question,but if the volume control works manually,and the motor is rotating too,it must mean that the drive belt is stretched and loose?.(very common problem)
You won't be able to turn the motor from the pully end as it is a step down gearbox.They are very reliable usually,although the internal grease can solidify if the unit has not been used for some time.
You seem to suggest though that the motor is actually turning?
Member Dillen can supply the correct belt which is crucial to proper operation.

Sorry I should have clarified; I was able to turn the motor by hand through the gearbox (I have since learned that I am not supposed to do this, however it appears I did not do any damage to the gears) but the motor does not turn when the buttons are pressed. The drive belt is in good condition and doesn't appear to be the issue. So, in summary, I am getting voltage at the motor leads, but the motor is not engaging, and I was able to turn the motor by hand, but the motor felt rather stiff. I've read elsewhere on this forum that some have encountered similar issues and were able to fix the motor by rebuilding it
You can indeed(with patience)dismantle the volume control drive motor,but try it first by connecting a small battery (9volt)across it to see it turns.Disconnect the motor from it's supply though,to avoid damaging the drive electronics.
If it does turn,it will suggest that the problem is in the drive electronics,which will be easier to sort out than dismantling the motor?
