This&nbsp;is very easy to clean using cotton buds and tapehead cleaner (isopropanol or carburettor alcohol - it&#39;s all the same).</p><p>When you have the belts dismounted, try rotating the motor pulley&nbsp;by hand. It should run quietly, no rumble. If the motor rumbles or clicks when rotated it will&nbsp;need to be replaced. Not&nbsp;too hard but requires a little bit of soldering and a couple of screwdrivers including a tiny watchmakers with a flat blade for the motor pulley grub screw. But check for belt residue first.</p><p>Martin</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/116819.aspxWed, 21 May 2008 05:56:27 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:116819patr5120https://archivedforum.beoworld.org:443/forums/thread/116819.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=116819Finally got the Beocord 200 running. ThanksMartin for the small belt. Unfortunately the drive motor sounds pretty noisy , a bit of a rumble and there is a rhythmic interference type crackle that comes through the speakers which seems to be to a similar beat as the motor noise. This is a unit that has probably had less than 10 hours use&nbsp;since it was bought in 1980&nbsp;So apart form the belts being in need of replacement&nbsp;, it is unlickley to be worn out.
