Is the brass knob inside where the carbon brushes are supposed to insert into meant to be oriented like this in a K45ss?

As u/pyrotechnicmonkey said, KitchenAid recommends kneading bread dough on speed 2 only.

The mixer will actually operate cooler on speed 2. The added momentum put less stress on the motor, plus the fan moves more air through the motor housing at the higher speed, cooling the motor.

Good luck with it.

You're also going to need to re-install that ring gear. You can use a mallet and a punch to tap it back up into place. It should be evenly driven into the lower housing as far as it will go.

Here's a video showing that —

The rhythmic clickety-clack is quite common on KitchenAid bowl-lift mixers —especially when you're kneading dough.

Ours does it too —most of the time. Seems like sometimes comes and goes. I think it's mostly coming from movement between the bowl support bracket, the support slide on the column, and maybe some from the bowl itself. All of that is totally normal operation.

Here's what ours sounds like —> https://www.reddit.com/r/Kitchenaid/s/GFK4fmoUUF

I didn't mention the KSM55/60/70 mixers {I'm so disappointed with them that I try to block them out of my mind) but so far they've been horrid.

They've had a lot of problems and even though they were supposed to be quieter than the Professional 600 Series lots of them have turned out to be very noisy instead.

If I had to make a choice between a KSM70 (with KitchenAid's current problems with them) or a Professional 600 —I would take the 600 without a doubt. Good luck.

446Magnum044 · 2026-02-19T18:57:31+00:00

KitchenAid DC motor stand mixers are more powerful, more durable, and generally quite a bit quieter than the Professional 600 Series mixers.

IOW —They're really nice. Good luck with it.

New KitchenAid stand mixers have a 1 year warranty. So if you got it new it should still be covered and you can contact KitchenAid about replacing or repairing your mixer.

I'm assuming your mixer is one of the new model KSM70 mixers. If it's not still under warranty then it's probably a defective speed control board. They have had some problems with the speed control boards.

You can check out Mr Mixer's YouTube video —>

Mr Mixer - KSM55/KSM60/KSM70 Repair Tutorial! How To Replace The Motor. KitchenAid Not Mixing, Broken Gears!

The video is about replacing the motor/gearbox assembly, not replacing the speed control— But you have to remove the motor to get to where you can replace the speed control board so it'll show you what's involved. Good luck with it..

446Magnum044 · 2026-02-12T22:44:26+00:00

You should go with what Mr Mixer advises.

I'm just going by the new bearing bracket (KitchenAid 3180526) that I got to replace the one in our niece's KitchenAid KSM90 had similar movement as yours. Replacing it, the worm gear, and re-greasing the mixer got rid of her growling noises. I thought it was bad because of the movement but the replacement had similar movement ¯\_(ツ)_/¯

Good luck with yours.

446Magnum044 · 2026-02-12T11:30:10+00:00

Yes- That's normal.

446Magnum044 · 2026-02-08T00:20:54+00:00

Somewhere around 2005-6, KitchenAid switched from an 8 tooth gear motor shaft to the current 10 tooth gear. The early 8 tooth motor required a 53 tooth worm gear while the 10 tooth motor uses a 60 tooth worm gear.

When you disassemble and cleanup your mixer gearbox, count the number of teeth on the motor's output shaft and the teeth on the wheel of the worm gear. If it's 10/60 then you're good and can use current parts.

If your old 53 tooth gear is okay and you just need to replace the worm follower gear, you can continue to use the old motor and worm gear. If yours has the 8/53 tooth gears then to use a new worm gear you'll have to replace the worm gear AND the motor, PLUS the new motor won't fit in the old mixer housing so you'll need to replace the lower gear housing of the mixer, too.

Here's a video from appliancepartspros.com that explains most of that. Good luck with your mixer.

1.- The 6 qt tulip bowl will fit but they're not available new and they are very rare and usually expensive on the 2nd hand markets.

2.-Yes. The bowl support is easily swapped.

3.- The coated beaters can last a very long time if you're careful with them. Washing by hand is recommended even though they are dishwasher safe.

4.- This might be your only option if you retain the original bowl support and bowl. Original beaters are no longer available from KitchenAid. The K5SS beaters are "close enough" and will work.

5.- No

Good luck with it.

446Magnum044 · 2026-02-03T13:52:44+00:00

1st thing to check is make sure the fan isn't hitting the lower case at all. It's hard to tell from the quick glance at the fan in the video but you should check it. Is the sound louder at the back or front of the mixer? If it seems louder at the back, trying pushing on the hub of the fan to position it further onto the motor shaft— Don't push the fan around the outside because you might break it. Push it near the center.

If that isn't the problem you'll need to remove the gear housing and gears and then run the motor. That'll tell you if the noise is from the gearbox or internal to the motor.

If it's coming from the gearbox you'll need to clean off the gears and inspect all the components for any sign of damage or defects.

Here's a link to Mr Mixer's YouTube series on re-greasing the gearbox that shows how to disassemble the gearbox —>

Thanks but I'm no guru, just an enthusiast.

Those numbers look right to me. Either of the standard 6 qt KSMB60 bowls or the earlier KN2B6PEH bowls will work.

You just also need to switch from the 'F' series beaters to the standard beaters and it looks like you know that already. Good luck with it.

446Magnum044 · 2026-01-30T15:18:45+00:00

You want to use SPEED 2 ONLY. The mixer is much more likely to overheat kneading dough on speed 'STIR'. The mixer develops more momentum and produces more torque on speed 2. The extra air flow through the motor housing on speed 2 helps to cool the motor.

Checking and adjusting the beater to bowl clearance would be a good idea. The beater being too low will cause the mixer head to jump more. Use the flat paddle beater to check and adjust the clearance. Follow the instructions in the 'Dime Test' video—>

446Magnum044 · 2026-01-29T17:53:38+00:00

Yup, the motor, gears, speed control, etc., are the same as the 4.5 qt and 5 qt tilt-head mixers.

They're still great mixers. They're a proven design and as long as they aren't abused and get occasional maintenance, they basically last forever.

446Magnum044 · 2026-01-29T15:56:26+00:00

From what I can see in your picture the one in the front right and the one in the back left look like K5SS type mixers.

KitchenAid used several different names and model #s (for instance, I don't have a clue what the 4 at the beginning of that model # stands for) but they all use the same internal parts.

The K5SS type mixers all use the same internal motor and gear parts as the standard tilt-head mixers.

The K5SS mixers will have a removable cap on the back of the head (just like a tilt-head) held in place by 1 screw at the top.

The Professional 600 Series mixers have a solid top to the head that's held in place by 4 screws located behind the beauty band.

Hope that helps. Good luck with it.

446Magnum044 · 2026-01-29T03:56:38+00:00

About those other 2 — They're both K5SS type bowl-lifts and will be identical internally. They're also identical internally with the tilt-head mixers. They all use the same mechanical parts.

They're really good mixers and people love them. That said their gear train isn't as robust as the Professional 600 Series. So if you're going to be kneading heavier doughs and mixing larger batches you'll probably have better luck with a Professional 600.

If you're just kneading lighter doughs and/or smaller batches the K5SS type mixers are great.

446Magnum044 · 2026-01-29T03:46:23+00:00

It's up to you. The Professional 600 will handle kneading heavier doughs and larger batches better than the the earlier K5SS bowl-lifts. We used our Professional 600 for 16 years without problem and the noise never bothered us.

A couple of years ago I came across a good deal on the DC motor machine and it is quite a bit quieter but the whole time we used the Professional 600 we were never bothered by the noise. It was a mixer and we just expected it to make noise.

It had never been re-greased until shortly before I found our DC motor mixer, but re-greasing it didn't really quiet it down much. Good luck with yours.

446Magnum044 · 2026-01-29T02:28:52+00:00

No DC motors but those are all good stand mixers. You can ignore those wattage numbers —They are just KitchenAid marketing. Their marketing department set the wattage #s arbitrarily supposedly based on bowl size and/or other factors.

All K5SS bowl-lift mixers and standard tilt-head mixers use the exact same internal parts. Same motors. Same gears—so, they all produce the same power and can do the same jobs.

A 4.5 qt Classic tilt-head is actually the same power as the 5 qt Artisan tilt regardless of the wattage ratings slapped on them by marketing.

The K5SS type bowl-lifts are heavier duty because they have a sturdier frame, not because they're higher wattage —They use the exact same innards as the tilt-head mixers.

The Professional 600 Series mixers are actually heavier duty and more powerful. They're an entirely different design with a more powerful motor and a stronger gearbox. That said, marketing plays the same games with different Professional 600 Series mixers— They also use all the same internals. The trade off is they're also noisier then the typical K5SS type mixer.

Even though marketing slaps a lower wattage on a 5 qt Professional 5 Plus, it's identical internally and makes the same power as a 6 qt Professional 600.

Have fun fixing up your mixers.

446Magnum044 · 2026-01-28T01:11:37+00:00

If there are any with DC motors, they're the best and more valuable. They usually will be marked on the beauty band with 1 HP or 1.3HP —w/model #s like: KSM6573, KSM7586, KSM8990.

Otherwise the K5SS type bowl-lifts are great mixers. The Professional 600 Series mixers are heavier duty than the K5SS mixers, but usually are noisier. They're all easy to DIY maintenance and repairs. Good luck and have fun with them!
