Worn out beater gears

Soft plastic gears inside the machine from what I've read around the web, sorry but you'll need a complete new mixer.

I've had one apart to see just how fixable it might be, and it took me about 30 minutes to get the motor and gearbox into a position where they could be looked at. The gearbox had 2 stainless steel clips holding the top cover on and I didn't want to pry at those in case the cover snapped.

Not a lot gained from looking inside it sadly.

Kitchen aid professional stops spinning

the pro series 600 has a worm gear, a worm follower gear, a bevel gear, and tree bearings the front rear and thrust bearings any of the above will cause the mixer to halt, to operate noisily, or grind, you need to open it up and look under the transmission cover. If it is an older model it could also be the transmission cover if it is a plastic one, My first thoughts is it is the worm follower gear. hope this helps you in the right direction.

Lower gears are slipping

I repair mixers and this model eats the metal gears like they are going out of style. If you remove the chrome band and the four screw holding the top on you will be able to remove the top. Towards the front of the mixer is the transmission cover. Hopefully your's is cast aluminum and not black plastic. Remover the cover and examine the gears. You will probably see gear next to the worm gear is severely worn. Be careful about ordering new gears. According to Kitchenaid they changed the teeth on the gear and the new gears will not work. The old gears are not available either. The fix is complicated and you probably want to send it in for repairs, then sell it.

Mixer has a broken gear or tooth in the head.

Hi. You have experienced the problem that many hundreds of kitchenaid mixer owners have. No doubt your mixer began having problems while you were mixing bread or cookie dough. Kitchenaid advertises that these mixers can handle these types of dough, the brutal truth is they cannot, for one very important reason. The cheap plastic transmission housing has failed, and as a result has caused damage to your mixer's transmission.

This cheap plastic part supports two of the most important shafts and gears in your mixer and has no business being installed in a high priced mixer. Heavy doughs place enormous stresses on these gears and shafts and this plastic part is not up to the task, Kitchenaid knows this of course, but refuses to issue a recall notice.

If your mixer is still covered by warranty, call Kitchenaid's so-called customer satisfaction dept. and demand a mixer replacement with a METAL transmission housing.

If out of warranty, unplug the mixer and don't use it. Remove the silver band from around the head of the mixer, then remove the four screws that secure the cover, remove it. At the front top of the mixer locate the transmission cover, if it's made of a shiny metal, you're in luck. If it's made of plastic, examine it carefully for cracks around the mounting screws or anywhere else on the housing. If you find cracks, you have found the culprit that has caused untold internal damage to yoúr mixer

If you are up to the task of repairing it, go to the website and do a search for your model's parts catalog. Download it, it will help with the disassembly and reassembly of the mixer.

You'll need to remove virtually all of the old grease. Remove the trans. components and wipe them clean, in order to correctly assess damage. When you determine which parts need replacement, you must insist on a metal housing when ordering parts. Try for parts. You can also order parts from Kitchenaid...Just be prepared to wait at least a month for them to arrive from Kitchenaid! "For the Way It's Made"?

Finally regrease with Chevron FM ALC EP-2 a Food Grade lube.

Be sure to tell the people at Kitchenaid what you think of their cheap plastic housing!

Stopped Mixing While Kneading Bread

Hi again Libby. You're right to be scared about further damage. If you want to fix this machine yourself, stop using the mixer. Go to the Kitchenaid website and download the drawings that match your mixer model Unplug the mixer! Take a screwdriver and remove the silver band from around the head of the unit ( 1 screw). Next remove the four screws that hold the top part of the mixer. Remove that cover, and look for a 'humpy" looking cover at the front of the machine. Examine this transmission cover carefully. If the cover is made of plastic, look for cracks. If you don't find cracks, you'be better off taking it to a repair shop. If you do find cracks in the plastic cover, remove the four screws that secure it. Remove the trans. cover.

You will now see a lot of grease in this exposed transmission. Put on some latex gloves, get a bunch of paper towels and move some of this grease aside so you can lift the worm gear assembly free of the mixer ( see Kitchenaid drawing). Wipe it off and look for damage to the worm (spiral) gear. Look for damage on the other gear of this assembly, inspect the 2 bronze bearings at either end of the shaft. You're looking for cracks in, or pieces missing from the bearings, look for damaged teeth on the gear. Should you find damage at any stage, that part must be replaced. These parts can be ordered from the Kitchenaid website, and will take about a month for them to arrive.

When you order the required parts, insist that the replacement trans. cover be made of metal. When my mixer "blew up", my replacement was a metal one. If your problem dosen't fit the above solution. I can't help you further. If it does, please rate my solution.

Depending how much grease you had to take out to do the inspection, you might have to order a container of grease to replace it. Good luck! ricardok45.

Kitchenaid mixer makes a clanging noise

Hi. If your mixer is under warranty, call Kitchenaid. They are very good at replacing mixers under warranty.

If you are out of warranty, this is where the fun begins, NOT!

Remove the silver band from around the top of mixer. Remove 4 screws that secure the top cover, remove cover and at the front top of the machine locate the transmission cover. Inspect this cover carefully for cracks. If you find cracks in it...You have just discovered Kitchenaid's dirty little secret. A cheap plastic transmission housing! The failure of this cheap part is the cause of all of the rest of the damage inside the mixer, which may include a destroyed worm gear and shaft, destroyed bearings and their seats. You're not alone. I estimate that thousands of these plastic parts have failed causing great damage to the rest of the mixer

Kitchenaid's replacement housing is made out of metal. If you feel up to the task of repairing the mixer yourself goto the Kitchenaid website and do a search for the parts catalog for your mixer model, these will assist you with disassembly, reassembly and parts ordering.

If you're not up to the task, take it to an authorized repair place once you have put the cover back on.
Even if you're out of warranty, you may be able to have Kitchenaid pay for the replacement parts, they did for my mixer. Be persistent with them and try to get to a manager with your complaint. This cheap piece of plastic has no business being installed on a high-priced machine.

Regarding the Sunbeam Mixmaster (model 2346): How do I remove the front cover of the mixer so that I may reallign or replace the beater gears?

Pry the beater release button out with a screwdriver. There are two screws underneath it and one under the motor housing between the the beater holes. This will allow you to remove the chrome front cover, but not the motor and drive assembly. Getting to the part that contains the gears requires complete disassembly of the mixer. It is not designed for service, and requires patience and a variety of tools to disassemble.

It has a metal worm gear and plastic drive gears. If the beaters are out of alignment, then one or both of the plastic gears are stripped and the mixer is junk. Repair plus shipping costs equals the price of a new mixer. This is the weak point of these mixers and a fundamental flaw in an otherwise robust and sturdy design. It is definitly not the same mixer *********** bought 30 years ago.

Hobart A-200 serial # ?

Hi. Your mixer was manufactured in 1967. If you plan on keeping it, take the outer cover off, gently remove the two metal dust caps with a small screwdriver and look into each opening with a good flashlight to determine the quality and amount of grease in the trans. case.

Ideally the grease should almost fill the space with no oil visible. If you need to look further, I suggest that you open up the transmission cover, to determine the condition of the grease that lubricates the transmission. If you find that oil is seperating from the grease. you would do well to remove all of the oil and old grease and replace it with either Shell Darina EP-2, or Chevron FM ALC EP-2 grease. It's a messy job, but it will add years of life to your mixer.

Check the planetary seal, remove, clean and regrease the planetary gearing. With a mixer of this age, you never know if it has ever been serviced since it's manufacture or not. The grease must totaly encapsulate the trans. gears. As the grease breaks down it's level lowers and it leaves some of the upper gears without lubrication, and will result in preventable wear.

Good luck! If you found this solution helpful, please rate it. ricardok45
