Step 4

              High and medium speed drive
  • Remove the Phillips screws to remove both plastic parts
  • The plastic parts are different
  • The screws are Imperial not Metric

Step 5

              Top Housing Cover
  • Remove the three torx screws
  • Lift off the housing cover
  • Pay attention to the white rubber buffer (red square)

Remove the three torx screws

Lift off the housing cover

Step 6

              Challenge: Unscrew the hidden screw
  • According to https://www.ifixit.com/User/1765524/jens, the plastic drive wheel can be unscrewed counterclockwise. To do this, the gearbox must be blocked. https://www.ifixit.com/User/730246/Julie… found a YouTube video documenting this. Starts at 7:25. Many thanks to Jens and Julien.
  • If the plastic drive wheel was removed in the above step, the next step can be skipped.
  • Loosening the Tx20 screw hidden by the plastic drive wheel is challenging
  • I was not able to pull off the plastic drive wheel
  • If you want to take a chance, you can drill a hole in the plastic drive wheel. However, I did not have the courage to do so.
  • I made myself a special tool -> see next step

If you want to take a chance, you can drill a hole in the plastic drive wheel. However, I did not have the courage to do so.

I made myself a special tool -> see next step

Step 7

              Special Tool
  • I machined a 6mm open end wrench to be form fit with the Tx20 bit
  • A slot has been cut in the screw for easier re-assembly

Step 8

              Open the gearbox housing
  • Remove guides (marked in red). They can be used after closing the case.
  • Remove seal. Has been replaced with silicone sealant.

Remove seal. Has been replaced with silicone sealant.

Step 9

              Planetary Gearbox
  • The one with the cross drive is the old one
  • The new one has a bayonet lock. However, the whisks and kneading hooks are in the same position, opposite of the mixing bowl.
  • Difference in gear thickness doesn’t seem to have an effect on the function.

Step 10

              Drive Gear

Step 11

              Labels
  • Cod. SER1018: Label from the plastic bag containing the three spare parts
  • Planetary gear label
  • 6-point nut: label and part

Step 12

              Insert Gears
  • Push each gear on its axis
  • Be careful with the spacers

Push each gear on its axis

Be careful with the spacers

Step 13

              Assemble the gearbox housing
  • There is a lot of grease in the housing. Grease all the parts to be well lubricated.
  • Replace seal. See step 8.
  • Stand the machine upright on its feet and place the arm in the horizontal position. With the arm raised, the shaft falls out from the slow drive.
  • Gently push the parts together.
  • When disassembling, the screws were loose. That’s why they were secured with a drop of screw lock.
  • Introduce the guides into the right places

Hallo , sehr tolle Anleitung!! Meine Frage - nach dem Tausch des kompletten Getriebes (keine Einzelteile wie Zahnräder und dergleichen) wird das Getriebe nach ca. 10 -15 min. Knetarbeit sehr sehr heiß! Man kann sich eigentlich daran Verbrennungen zuziehen. Was kann da die Ursache sein??

Vielleicht hast du eine Idee dafür?

Lg Heinz

Hallo Heinz

Folgendes fällt mir zu der Frage ein:

  • Das Getriebe sollte leichtgängig sein wenn man am Kunststoffzahnrad dreht. (Ohne Zahnriemen)

  • Ist das eingesetzte Getriebe geschmiert? Roter Zapfen beim 5. Schritt

Gruss Bruno

Hallo Bruno,

das ist ja eine geniale Anleitung - KOMPLIMENT!

Bevor ich das Gerät zerlege, hätte ich eine Frage.

Zwischen Gummi und Planetengetriebe (siehe Bilder Step 1+2) fallen im Betrieb schwarze Krümel raus…

Was könnte das sein (hart gewordenes Getriebefett)?

Danke

Peter

Hallo Peter

Da kann ich Dir leider nicht wirklich helfen.

Ich vermute eher verschüttete Lebensmittel.

vielen Dank für die detailierte Anleitung. Mir ist es gelunge das grosse Kunststoffzahnrad abzuschrauben, obwohl das verlinkte Video nicht funktioniert. Bei mir ist aber der untere Getriebedeckel gebrochen. Daher meine Frage: wo beziehst du deine Ersatzteile? Die meisten kommen aus UK oder Italien oder aus “zur Zeit nicht lieferbar”. Gibt es noch eine schlaue Quelle die Dr. Google unbekannt ist?
