Just got round to rebuilding my cyclone - bought it second hand a few months back. I've been trying to return it to factory spec until I came across something really odd in the manual. The previous owner had a spool arangement on the spur gear shaft, but when built to the manual, there is a one way bearing. I built it as the manual but I couldn't understand why the bearing was rotating the wrong way. But then I looked at the exploded diagram at the back, which shows the spur the other way!
