Kenwood Chef model 701A?
With K beater fitted, mixer was on low speed and suddenly there was a screeching noise. beater then made a clicking sound as it turned very slowly.
Motor is OK and runs normally. I removed the cover under the arm and can see the drive belt, which looks OK. Fault seems to be somewhere in the arm, but I'm unsure how to gain access to these parts
