I also need to get into the motor assembly housing to change a part but can’t see how it comes apart!!
Once the handle covers are removed, the next bit is to gently lever off the speed control knob – it’s a tight friction fit, then undo the nut holding it to the handle cover panel. After this undo the mains power connections from the multi-block joiner they go into then remove the 2 screws securing the mains wire. Then undo 2 bolts at each end of the handle going downwards into the main body. At this point the handle can be removed as well as the top body plate. You have to fiddle the electrics and switches through the hole in the top body plate to remove it. Now 3 bolts and a small crosshead screw is all that holds the upper motor section to the lower. Remove these and you can separate the 2 halves which gives you acess to the water pump. This is held in by screws founf underneath the plastic ring at the base of the motor body (around where the small reound blue sponge filter goes). This ring is held in by plastic springy clips. Gently lever round it to get it come off.
On my Hoover dust magnet cyclone cylinder machine I found another filter beneath the plastic box that collects the dirt & dust. I removed it and washed that too. I didn’t know there was one there until I read it somewhere. You shouldn’t use soapy water to wash it, just plain, cold water. It has made a big difference to the vac’s performance.
I think you are trying to do the impossible but try this site.
If the armature is worn like an apple core or if the lines between segments on the copper commutator are gaping and not parallel you will need a new or rebuilt motor.
If brushes are properly removed there is a tiny flag terminal which will slide out of most brush housings where the wire meets the brush itself. New brushes are best installed after dressing the armature surface with a fine carbarundum seating stone or very fine wet dry sandpaper and then the motor is run in at half speed at reduced voltage.
|There is usually a hold down clamp over each brush to seat it and a lock tab underneath to align the new brush.
