    the mixer is a KitchenAid 5KPM50 heavy duty model

  • chris constable Aug 22, 2010

    I have looked at the diagram but it doesn't help.

  • chris constable Aug 22, 2010

    I have taken pin out and thought that would allow access to the 5 screws to complete access to worm screw gear

  • chris constable Aug 22, 2010

    Thanks manual perfect for my needs.

  • chris constable Aug 22, 2010

    thanks very much. I was doing the right thing, but needed confirmation that I was right before applying the extra force needed to remove the planetary.

I can direct you to the assembly diagram of the case for this unit. Note Kitchen Aid is made by Whirlpool.

This should give you some idea of how the screws and pins are held together. I would suggest you take a video when you are disassembling. That way you will not miss any intricate step when you are putting it back together.

Good Luck

    I am pretty sure this maual will have the answer your looking for. The basic units are pretty much the same. Operating voltages are different by geographic location. I still think this will work for you.

Runs but doesn't turn. Worm gear is not broken.


Something must be broken if the motor is turning and the planetary is not. It will be one of the following, we will start from the first point of contact with the armature
1) Worm gear broken (fuse gear) you say no teeth broken
2) Worm gear not broken but whole unbroken plastic part not gripping aluminium boss
3) Pin through worm gear broken or missing
4) Pin through centre (or bevel) gear broken or missing
5) Pin through small gear in planetary broken or missing
6) Pin through planetary hub centre shaft broken or missing

The most common ones in order of likelihood are, 1, 2, 3 and 6

Mixer noisey and not going round freely


Your mixer most likely has a stripped gears, or a combination of stripped gears. The 5kpm5ewh is an international model similar to the ksm5. The gearing inside the mixer will be the same, some of the electrical parts may differ.
Your mixer has a nylon worm gear inside, this is the most common gear to strip inside the mixer. I would recommend opening the mixer and inspecting all of the gears before you place an order.

Most likely you will need the worm gear, which is available by itself (http://www.mendingshed.com/kawormgear.html) or you can get it in the whole worm drive pinion gear assembly (http://www.mendingshed.com/kitchenaidgearassy.html) the whole assembly is a lot easier to replace, and will save you a lot of time. You may also need to replace the grease inside your mixer, KitchenAid recommends the Benalene 930-2 food grade grease, it is only available in a 30oz can (http://www.mendingshed.com/kagrease.html) And you will also need to replace the gearbox gasket (http://www.mendingshed.com/mixergasket.html).
To aid you in your repair, here is a link to the KitchenAid service manual (http://lib.store.yahoo.net/lib/mendingshed/kitchenaidservicemanual.pdf) This will walk you through how to take apart the mixer, replace the gear, grease and gasket, and reassemble the mixer.
Thank you,

On low it makes a really loud grinding noise the higher you turn up the speed the slower it becomes.


It sounds like the Worm Gear is going out. The faster the motor runs,
the more damages the Center Gear is grinding away the teeth of the
Worm Gear. Things start to slow down, and eventually they will come
to a halt. It's time to replace the Worm Gear. Also make sure to use
new fresh Kitchenaid Food Grade Grease with the new replacement.

Mixer makes a clicking noise and beater stops turning or mixing...gear seems to be slipping...


The only part that consistently wears out is the Worm Gear Follower located inside the Transmission housing. The teeth are wearing out and becoming chipped. The clicking noises you hear are made by the Worm Gear banging on the Follower. All the teeth of the Follower are now damaged and the Planetary stops rotating.
Removal and replacing of the Worm Gear Follower is no easy task. Let me know if you need help.
(Do not try to remove the Planetary assembly by forcing it with a screwdriver. That is not how it's done.)

While kneading bread my mixer suddenly starting hanging up at the back side. It makes the full circle but when it gets to the back it stops and "hums" and then sometimes will go on but most of the time...


It sounds like you have lost some teeth from your worm gear. This usually happens when the mixer has been overloaded. The teeth on the worm gear are designed to fail first to prevent more serious damage. To replace the part you will need to open the head on your mixer. The gears are at the front of the mixer packed in grease. It should be obvious that the worm gear has broken once the head is open. If it is not the worm gear, with the head open it should be easy to spot the problem. The gears are available as spare parts from several places on the internet. search for "kitchenaid worm gear"

When you replace the worm gear, you should be able to see if you need more grease. This will have been the "oil" you saw escaping.

Replacement parts for Wolfgang Puck stand up mixer


Very close; stand mixer parts (included accessories and manual only) can be accessed from this page:
http://www.wpcookware.com/categories.asp?cat=32
Just select your mixer's part number (located on a sticker inside the base) and click the link for a list of available parts. You will have to create an account to see anything useful, but all they ask for is your name, a password and an email address. When adding items to your shopping cart, be sure to check the 'Select Item' box. The ordering page will ask for the usual info. Prices are reasonable, but beware the shipping cost!
