Turn the lower body over so you are looking at the gear assembly of the cleaner. Pop the oscilator chamber cover off the gear assembly, it is held in place by 2 latches on either side. On the gear set not directly on the oscillator shaft there is a screw you must remove to extract the assembly. Once this screw is removed lift the gear assembly out of place, be sure not to alter the gear placement in anyway.
