Remove all hoses have then undo the Phillips screws that hold plastic body in place 5 or 6 usually

Remove one Phillips screw holding switch assembly and pull off switch bracket

unhook motor connecting wire loop from support bracket, lifts out

Lift out motor it helps if you Mark top of motor for reassembly later. Remove rubber seal at front, note how it fits for later

You are going to remove outer fan cowling

This is done by pulling it off with immense strength of by gently tapping with screw driver blade on edge of cover

Remove spacer washer, note how it fits

Now remove star screws to remove plastic plate

Remove motor brushes at 12 and 6 oclock, should now look like this

Lift out motor armature assembly clean and replace bearings. YOU NEED TO MEASURE AND NOTE EXACTLY THE POSITION OF THESE BEARINGS TO THE mm wAS ANY ERROR IN REASSEMBLY WILL BE CATASTROPHIC.

Note washer below top bearing (this is the hearing most prone to fail). The bottom bearing may not need replacing. Carefully lever this washer down until it sits on top of armature cylinder. After you remove bearing washer will come off too. Crimp inner did it washer with small pliers and replace in original position prior to fitting new bearing

Imagine (I forgot to photo) the washer is sitting flush on the armature this leaves a gap to insert a thin bicycle spanner or similar

the tricky bit another pair of hands is useful as is a vice or work bench or sturdy work table. Place the spanner under the bearing and place the spanner in a position on a bench where it takes the weight. Tap gently on motor shaft with hammer out scrap yard wood in between, saves the threads.

The bearing will drop off. Place the new bearing on shaft and tap down using a mild steel pipe that is just bigger than shaft in other words rests on the inner bearing ring only. Tap down into exact position you noted in measurement before. To the mm!

Repeat with bottom bearing but if bottom bearing looks OK don't bother. Replace motor in housing. THERE IS A SPRING CLIP AT BASE OF MOTOR HOUSING MAKE SURE IT IS IN PLACE TO REST BOTTOM BEARING ON. Once motor is seated you can test by gently pushing on shaft end you should feel a couple of mm springy give.

Now just repeat in reverse the disassembly steps. Replace plastic housing star screws. Replace washer position fan and top washer. Replace fan using CLOCKWISE action, left thread. Replace fan cowling etc etc you get t he idea. Good luck. My Miele is now been going 30 years on third set of bearings they cost £3 each
