Bosch 1600 Express Belt spindle noise

[Sarahh]

Hi, I have just replaced very worn brushes on motor, when I refitted belt I have now a noise - when belt not on no noise - when I turn the spindle( that belt goes round)  without belt on no noise in anti clockwise direction , ratchet sound clockwise. Belt has no sign of wear - machine worked quietly until this point. Belt is a snug fit when I stretch belt and rotate spindle noise goes. Any ideas?  Spindle listed on diagram but not in partnumbers.  Drum bearing okay. Any ideas?

Hi - I had a slight query on one of the brushes I had replaced and marked before I reassembled because it popped out when fitting .  So I restripped machine I reisntalled the other way round and the problem is fixed.

Yes if you fit a carbon brush the wrong way around it can make a very loud ratchety or clicking sound.
