20 Most Recent KitchenAid K5SS Heavy Duty Commercial Stand Mixer - Page 7 Questions & Answers

If lightly tapping the beater to get it to compress the spring does not work then you can drive the pin out that holds the beater on.

Once the pin is out you should be able to wiggle the beater and pull it straight off the shaft without having to push it up and rotate it first. If necessary just tap it lightly and it should slide off. Then you can replace the pin and lubricate the shaft with some olive oil or other cooking oil

It appears that retaining ring (7) has snapped. It is the retaining ring which attaches to the drive shaft. Here is the parts diagram:

From it you can see how to remove the case cover and access the gear train. You may have to replace the shaft if its groove is worn allowing the retaining ring to slip off.

2818 Sunset Place, los angeles - (310) 600-6007

I have never used any of these places so I can't recommend them or tell you anything about them. I got them thru Google.com

Although I can't find your mixer by the model number you gave me, I assume that your mixer is the kind which the bowl moves up and down not the "tilt-head" style.

See pg. 12 of the owners manual for bowl height adjustment procedure:

http://shared.whirlpoolcorp.com/assets/pdfs/literature/Use%20and%20Care%20Guide%20-%209707946.pdf

There is a screw in the base of the mixer which is turned
clockwise to raise the bowl
and counterclockwise to lower
the bowl.

Hi ALLENJUJU. To replace the agitator shaft will require a significant amount of extra effort, but will be well worth it in terms of gratification and reward for being able to successfully do it yourself. First, I’ll assume your mixer is no longer under warranty. Second, I’ll assume you have your Repair Parts manual on-hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this manual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) and then check to verify this matches your mixer model.
Turn to pages 4 & 5, titled: “Case Gearing And Planetary Unit” which shows you an exploded view of all the mechanical parts and assemblies for your mixer.
I highly recommend the following website that provides you step by step instructions with pictures (worth every bit of a 1000 words) to gain access to your planetary housing and agitator shaft. The mixer displayed is a different model (tilt-up) than yours, but the ‘insides’ are the same.

It would be helpful to have the following tools available as you begin to disassemble your mixer: a flat screw driver, a small Phillips screw driver or a punch drive, a pair of retaining clip/ring pliers, and a hammer.
You will need to remove the Planetary Drip Ring (Illus. No. 42) and Pin (Illus No. 25), which secures the Planetary Housing (Illus. No. 33) to the Center Vertical Shaft (Illus. No 19). (See pictures 6, 7 & 10, 11 from the link).
You’ll need the punch drive or small screw driver with a smaller diameter than the pin, a hammer, steady hands and plenty of patience. Rotate the planetary housing to expose the retaining pin with the vertical (center) shaft.
After removing the Planetary Housing, remove all the residual grease from the 18 tooth Agitator Shaft Pinion Gear (Illus. No. 47), which should expose a Retaining Clip (Illus. No. 61), which will need to be removed. With the Retaining clip removed, the pinion gear and Shim Washer (Illus No. 45) should easily slide off the top of the agitator shaft and you should be able to pull the agitator shaft down through the planetary housing bushing.
Take your new, replacement agitator shaft (be sure you’ve got the lower groove pin ordered, too, and insert through the bottom Planetary bushing. Replace the shim washer, 18 T Pinion Gear and Retaining Ring. Grease up the whole works with new grease, and reassemble the opposite of how you took it apart.
Here are five potential online vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). You should search for ‘food grade grease’ online (although I’ve seen automotive bearing grease used too – your call). Prices can vary widely between vendors, so do some comparison shopping.

Hi ALLENJ740, I believe the ‘knob’ that you’re referring to on the agitator shaft (rotating column) is called a ‘groove pin’, and you should be able to replace it yourself. Before you get started, it would be helpful to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this manual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) and then check to verify this matches your mixer model.
Turn to pages 4 & 5, titled: “Case Gearing And Planetary Unit” which shows you an exploded view of all the mechanical parts and assemblies for your mixer. Locate Illus. No. 40, Agitator Shaft, Part No. 4176067. Unfortunately the ‘geniuses’ at KA didn’t identify agitator shaft ‘groove pin’ for this model series...duh?
Sooo download this Repair Parts manual file K45SSWH0.pdf (341.41 KB) for a K45SSW model. The K45SS model and your K5SS model share the same agitator shaft part number, and in this manual Illus. No. 21 identifies the ‘groove pin’ (Part No. 9704677), which is the ‘knob’ part you need to replace.
You will need a punch drive with a smaller diameter than the groove pin, a hammer, steady hands and plenty of patience. Rotate the planetary agitator shaft so that the flush end of the groove pin with the agitator shaft is facing you (the extended part (knob) of the pin – or where it used to be - is facing away from you). Align your punch drive on the end of the groove pin and give it a good whack; repeat until the pin starts to come out the other side of the agitator shaft. Continue tapping until the pin comes completely free. Note the groves on the pin as you will need to orient the replacement groove pin the same way when you place it back on the agitator shaft. Just reverse the process. You’ll want to tap the groove pin home to make sure it’s securely in place. You don’t want it to come loose while mixing.
Here are five potential online vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). You should search for ‘food grade grease’ online (although I’ve seen automotive bearing grease used too – your call). Prices can vary widely between vendors, so do some comparison shopping.
Also, for future reference here are links to three excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers displayed in the links are different KA models, but the principles are the same.

• http://www.neilcrockett.com/mixer.htm
• http://www.foodonthefood.com/food_on_the_food/2009/04/how-to-repair-a-kitchenaid-mixer-yourself.html

Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble, troubleshoot, determine appropriate repair parts and reassemble your mixer to get it working again. Good luck. I hope this helps. Howard, Burke, VA

Hi SHIRLAFINK, you do not need to 'oil' the transmission gears on a KA mixer. Your KA mixer comes with enough grease to 'last a lifetime' - whatever that means?

Depending on the age of your mixer and how heavily you use it, there may be a time when you might want to replace the grease, but that period is usually measured in years of useage.

Of course if one of the gears strips or breaks, you will need to replace all the grease when you replace the broken gear. Attempting to use salvaged grease jeopardized the remaining gears if pieces of metal or plastic debris are suspended in the old grease.

I hope this helps - hslincoln, Burke, VA

This is a bad rheostat switch. You will need to visit a repair center to have this fixed or get the part you need.

Hi DENAULTR, this is a repeat of my previous answer to your problem. It would also be helpful to have the Parts List manual on hand. If you're lacking one, you can download a PDF version Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this manual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) and then check to verify this matches your mixer model. Turn to pages 6 & 7, titled ?Motor And Control Parts?, which provides an exploded view for the disassembly and reassembly of your mixer?s electrical components, along with all the part names and numbers. Locate Illus No 47, Brush holder assembly that includes Illus. Nos. #28, 32, 33, 34, & 46, and Illus. No. 29, Brush & Spring assembly respectively. Make sure you orient each bruch correctly following the illustration here: The Parts List diagrams along with the picture above regarding the orientation of the brushes should get your mixer powered back up and operational. Good luck! I hope this helps. Howard, Burke, VA If this solution has been helpful to you, please rate it, thanks! -hslincoln

HI KEN9486, from the way you describe your mixer’s malaise, the apparent lack of power during the dough mixing process does not appear to be to be a mechanical issue, but electrically induced. You’ve already put your fingers on the culprit – the brushes! Anytime your mixer’s brushes have been worn down as much as you indicated, they should be replaced.
Be sure you have the Parts List manual on hand to order the correct brushes. If you're lacking one, you can download a PDF version from the KA website: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this manual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) but check to verify this matches your mixer model.
On Pages 6 and 7, you will find the brush & spring assembly (Illus. No. 29) and Part No. 9706416 that you need to order. Replace them both.
Here are five potential online vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). Prices can vary widely between vendors, so do some comparison shopping.
I think you’ll find new ‘life’ in your mixer after you’ve replaced the brushes and it should be able to handle dough mixing without further problems. Good luck, I hope this helps. Howard, Burke, VA

HI PANNABECKERS, sorry to hear about your mixer’s malaise. It is very disconcerting to purchase an expensive brand name kitchen appliance with a solid reputation and find the reality falls far short of your expectation, but I digress on KA quality. You don’t say how old your mixer is, but I’ll assume it’s no longer under warranty (you’ve had it over a year).
By the description of your mixer’s symptoms, I concur with your assessment and say that your mixer is headed for some type of mechanical /transmission breakdown, if it hasn’t failed completely, yet. What can you do?
The good news is that this can be fixed quite easily (OK, maybe with a little effort) by yourself, if you are a DITY type person, feel adventurous, and your mixer is not under warranty you can troubleshoot it yourself. Be sure you have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this manual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) and then check to verify this matches your mixer model.
Turn to pages 4 & 5, titled “Case, Gearing and Planetary Unit”, which provides and exploded view for the disassembly and reassembly of your mixer, along with all the part names and numbers.
To disassemble your mixer you will need a regular and Phillips screwdriver, snap-ring pliers, a small drift pin punch and a small hammer. By using the exploded views in the Part List manual, you should be able to disassemble, inspect, identify and replace broken/worn parts, and reassemble your mixer.
After clearing all the grease away, check to see if the gears are just loose, excessively worn or broken. If it’s worn or broken you can order replacement parts and install them yourself.
Besides a replacement gear, and grease you might consider replacing the gasket, too. You should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call). It can be messy but quite gratifying to diagnose and repair your KA mixer yourself.
If you do need repair parts, here are five potential online vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). You should search for ‘food grade grease’ online (although I’ve seen automotive bearing grease used too – your call). Prices can vary widely between vendors, so do some comparison shopping.

Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer, should you decide to go that route.
If you feel this repair is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping. I hope this helps. Howard, Burke, VA

the rotating plate needs to be pulled of and clean the grease out and only put two teaspoon dabs on ether end. to pull it of you will need to push the pin in the middle out and just lightly tap it back in.

Hi WWW_SOCRAFTI, you can easily download both the Owner’s Manual and Parts List manual for your K5SS mixer online from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this model range), and then select this file: KSM50PPWH0.pdf (5156.65 KB) from the Owners Manuals (9) list and this file: KSM50P.pdf (438.31 KB) listed under Parts List (4). Check to verify they match your mixer model. You can save them to your PC hard drive, and then you can print a hard copy if you wish, or just refer to it when you need to use it.
The reason I suggest downloading the Parts List manual is that should you decide to try and troubleshoot and fix your KA mixer, this manual will be invaluable in the disassembly and reassembly of your mixer along with listing all the part names and numbers. Having the correct part names and numbers is critical when reordering replacement parts when your mixer eventually will stop working.
Good Luck with your mixer, I hope this helps. Howard, Burke, VA

Normally you would not remove the spring for cleaning. It should not come in contact with any ingredients under normal operation. If you need to remove it you will need to punch the pin that holds it out using a suitable punch and hammer.

I think you have a K45SS. It sounds like there is a problem with one of the gears, probably the worm gear. The worm gear is designed to be the first to fail if the mixer has struggled with a heavy dough or other difficult to mix substance. The best way to establish the cause will be to open the head up and check the gears for signs of damage.

Motor brushes are fairly cheap to buy. It sounds like the first place to start: http://kitchenaidmixerspares.co.uk/Home/tabid/36/ProductID/88/Default.aspx

It sounds like you need a new speed control phase board:
