KAMBROOK PLANETARY MIXER KEM500 REDANZ - Food Mixers

You are going to need to remove the top housing and look inside, there is a circlip on the main planetary shaft that retains the planetary and mixer shaft assembly. You may get away with a new circlip but if the groove that engages the circlip is damaged you'll probably need to fit a new planetary as well.

I haven't seen enough of that model to remember, look up a local service agent and ask them is probably your best option. Whoever does the warranty repairs for Kitchen Aid would be the best person.

Edward, it sounds like your planetary is starting to separate.Where the center shaft connects to the planetary commonly separates, the pieces are machine pressed together, and can separate, usually your beater, and planetary plate will just fall off into the mixer, while the center shaft stays up inside the mixer with the gears on it.

What you will need to do is buy a new planetary assembly, you do also have the option to have it pressed back together by a machinist, but it is usually cheaper just to buy a new planetary. According to your model number you have a Onyx Black mixer, here is a link to the replacement planetary on our website: http://www.mendingshed.com/9708176.html

That should solve your problem, also here is a link to the service manual in case you need any help taking the mixer apart: http://ep.yimg.com/ty/cdn/mendingshed/kitchenaid6qtservicemanual.pdf

And of course, if you need any help you can call us and speak with a KitchenAid technician over the phone

Thank you,

The planetary is replaced by removing the chrome drip ring from the housing and then knocking the through pin out that holds the planetary hub onto the shaft from the gearbox. In New Zealand the planetary comes as individual parts not an assembled unit so will certainly look different to the full assembly you take off. The lip of the planetary ripping off is most likely caused by one or more of the 5 gearcase screws under the planetary coming loose and rubbing. Check the other 4 (total) screws at back and middle of gearcase as well.

The problem will be with the worm gear, if the gear is not stripped then check that the locating pin for the worm gear is not broken or missing. Occasionally the plastic gear can detach from the aluminium boss between plastic and shaft. The worm gear is the 99.9% place where drive can slip. Afterthought, I suppose the planetary pin is not missing or broken??

we need more info and clarity first we will need a model number for your mixer before we give any advise, next what head falls off, the planetary if so then i will assume that you have an accolade professional or pro series or pro 600 mixer, in which case you need to order a new planetary for your mixer. (planetary is the part that the beater is attached to) please send us more info so that we can help you

Is the planetary still off before the taper pin is in place?

It's a shot in the dark but if everything lines up, I can think of two possibilities:

1. The taper pin in backwards, and
2. The shaft hole in the planetary is out of round.

The Planetary plate comes attached to the shaft from the factory. It is not supposed to get
loose and come apart but it often does due to the mixer's vibrations and the user's constant
attaching and removals of the flat beater, wire whip or dough hook onto the beater shaft.
Try to remove the Planetary plate first : Gently rock it from side to side while pulling on it
to separate from the shaft. Notice the groves on both the shaft and inside the planetary
housing. That is how they are attached to one another at the factory (just friction, no screws
or pins). Now for a permanent solution:
Take a trip to Home Depot or Ace hardware and buy the J-B Industro Weld Compound
(Not the 5 minute type). Mix an equal amount from both tubes (Black and Red). Use a Q-Tip
and apply a thin layer of the mixture on both the shaft (grooved section) and inside the
planetary housing. Now re-attach the planetary plate to the shaft. Use a long strip of duct tape
to hold the plate in place (to prevent it from falling back out). Allow the epoxy to dry overnight
or at least for 8 hours.
The Planetary assembly is now permanently attached to the shaft of the mixer.
