Introduction

Si les roulements sont usés ou si le ventilateur est endommagé, le remplacement de l'ensemble des roulements est nécessaire. Après l'ouverture du boîtier, le palier peut être retiré à la main.

    • Commencez par retirer le couvercle du boîtier en le dévissant.

    • Ensuite, dévissez l'écrou de la pince de serrage maintenant exposé tout en maintenant enfoncé le bouton de verrouillage de l'arbre.

    • Pour retirer l'écrou de la pince de serrage, vous devrez peut-être utiliser la petite clé à fourche fournie avec le Dremel.

    Is this a joke??? Wanna maybe possibly tell US WHAT A COLLET NUT LOOKS LIKE?? I mean it's obviously very exposed (not exposed one bit. My Dremel 4000 looks exactly like it did before. No Collet nut suddenly stood out) and not all of us have advanced degrees in Dremel parts

    Dam Jeff. I am not sure if you are being sarcastic or not, but maybe you should go lie down for while.

    • Avec vos mains, retirez soigneusement le cintre du boîtier.

    Mine seems to have solid caps without the slot. How are this type removed?

    This is getting worse. Maybe skipping the Collet Nut part threw me off - as there is no hanger. This description is PATHETIC!!!

    Jeff Wagner -

    I love how these pictures show you NOTHING related to what this guy is talking about

    Jeff Wagner -

    Wow, you guys are really amazing. Are you actually working on a Dremel 4000? Mine looks exactly like the pics. It has a hangar on it, as well as a collet nut.

    • Retirez les capuchons des brosses (un de chaque côté) à l'aide d'un tournevis à tête plate.

    • Les capuchons des brosses sont à ressort.

    I have found that the brushes are the most likely failure point on the Dremel tool. I haven’t purchased a new one in many years but they used to come with a spare set.

    In general commutator brushes are made of a soft high carbon compound, usually found with new springs attached. The brushes can be carefully reshaped using files, sandpaper and a razor knife to fit the recesses of the tool.

    Use the original to get necessary dimensions, a dial caliper is very helpful here to duplicate channels and recesses as well as determining how long the brushes should be. Should you need to shorten the brush a new concave can be established using a pencil or dowel wrapped in sandpaper being sure to match the concave to the channels so it matches the armature. It is preferable the curve be wider than the armature so edges don’t catch, it will naturally wear into a perfect curve. Blow off before installing.

    Once the tool is reassembled turn on and off several times then run for a while varying the speed.

    • À l'aide de la pointe du tournevis Torx 15, retirez les 5 vis (12,5 mm) qui maintiennent le boîtier ensemble.

    • Utilisez un outil d'ouverture en plastique pour écarter doucement les fils en plastique dur.

    • Pour dégager l'accès à l'ensemble électrique, retirez le capuchon du cadran à vitesse variable et le levier d'alimentation bleu, et mettez-les de côté.

    • Avec vos doigts, retirez délicatement la carte de circuit imprimé du boîtier. Il sera ainsi plus facile de retirer le cordon d'alimentation.

  9. phYVEECqJuWdkBXw

    • Chaque fil passe par une petite ouverture sur la carte de circuit imprimé et est maintenu par une vis à tête plate.

    • Desserrez la vis juste assez pour retirer le fil en le tirant doucement avec votre main.

    Hello I need to know or see where is plugged the blue wire, I think that know the problem it is disconnected? Thank you. if you need my e mail. charbonneau_eric66@hotmail.com

    on t11 and t12, which one is positive and which one is negative?

    Marc Webb -

    Hey Marc, the leads that go to T11 and T12 are mains (AC) current. The black wire goes to T12, and white to T11.

    • Retirez soigneusement les deux fils du circuit imprimé avec vos mains.

    • Notez bien de quel côté se trouve le fil noir et de quel côté se trouve le fil blanc.

    • Tirez prudemment sur le puits pour le sortir du boîtier.

    The blue wire has a seat below the brushing casing of the Dremel bottom assembly (you can see a little notch). Thus place the blue wire before putting back the stator…

Nice guide. FYI, I've found that removing the rotor/bearing assembly is just as easy without removing the input power wires.

Chris Barth -

Absolutely, it is.

josephbolton -

yeah why did we do that?

Junk McNuggets (Junk; Justin) -

thats an abrupt end for someone trying to learn all of this the first time. which one of those is the field assembly and which is the bearing assembly? my guess is the bearing assembly is the cylinder looking thing on the right...

and then what? it just says do it all backwards to put it together again...? whyd we take it apart for? mines whistling or squealing or just going "EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE..." when i turn it on. just started today too. am i supposed to just, like, smack this can shaped part on the table and then cram it all back into its plastic case?

i mean, that works when the kids are acting up so im gonna give it a try.,..

Junk McNuggets (Junk; Justin) -

Disassembly is shown, but main action of removing ball bearings from the shaft of the armature - vital essential sequence of removing - how to remove the collate pipe from the armature shaft, then how to pull out, ball bearings from the armature shaft is not shown. That is the most important procedure. No one wants to replace the whole armature and ball bearing assembly, at unnecessary high cost when the armature is okay. Please show how to remove ball bearings and replace them on the existing working armature.
