3KSM5CBTER0 KitchenAid Mixer - Instructions

I disassembled the mixer using a YouTube video as a guide. Disassembly was easy, as everything was held together with pins and threaded fasteners, and all electrical connections were plug-on.

Cleaning out the old grease was messy and time-consuming. I used a putty knife, screwdrivers (used them like small putty knives in the crevasses), paper towels, and finally, small cloths dampened with alcohol. After about a hour (maybe 90 minutes) everything actually looked like new.

I originally diagnosed the problem as the plastic gear loosening up from it's hub, so I ordered the complete gear tower assembly. It turned out not to be the problem- the gears were fine. With the gears removed to eliminate load, I applied power and saw that the original symptom was still there.

Further research turned up that this symptom is more likely a failed field coil, or possibly the phase control board. I ordered both from PartSelect. In the meantime, I tested the armature by measuring the resistance across the brushes as I slowly turned it by hand. At every angle, the resistance was about 7.5 ohms. Nothing lower, and no opens, so I'm pretty sure the armature is OK.

The phase control board arrived, but as of this writing, the field coil has been back ordered for almost a month. While I waited, I tried a partial reassembly of the head with the new board, and it worked! This weekend, I'll finish reassembly of the motor unit to the base/gearbox and calibrate the speed governor. In addition to the new gear tower and phase control board, it has new grease, seals, and both side levers (tilt and speed control) that had lost their knobs some time ago.

Hopefully it will be ready for another quarter century of use!

Followed step-by-step video instructions for dis-assembly/reassembly found at ereplacementparts.com. All went well except when driving out the pin that holds the worm gear in the tower. The video wasn't exactly clear enough about what position the pin should be in when driving it out and I inadvertently drove the pin out so that it was trapped inside the tower assembly. Result? I had to bend the pin to get it out, causing an extra expenditure and wait time to order a new pin. So, lesson learned: be sure the pin is horizontal to the tower and not perpendicular to when driving the pin out. Also, I found that having the mixer apart was a good time to replace the grease in the housing. I don't think it would be required to replace the grease at this time but I was worried that pieces of the old worm gear could remain in the grease and possible get jammed in the gears after repairs were completed. Be sure to get a "food grade" grease not grease from your local auto parts store! The table knife was the best tool to use to remove the grease and to smear the grease all over the internal gears when replacing it.

I called my fiancée.

I first ahd to remove the original feet by removing screws that held them in place. The new feet that I purchased were different then the original. They were a push in type and not held in by screws. I had to modify the base by drilling the foot holder to accept the new style feet. Once this was done, the feet were installed and looked good.

repair is farly simple just take your time, First attempted i didnt replace the speed covernor looked ok but had problems getting slow end to work properly decided to go ahead and install since i purchased it also and walia took care of the cogging problem. Good Luck

Two flat head screws removed, swapped out the latch, and replaced.
The entire repair took about two minutes.
Price was acceptable given the worth of the mixer.

unscrewed the old one........screwed in the new one, no chance for electrocution or power tools..........darn!

removed the screws holding the mixer housing and then removed the worn worm gear by removing the roll pin holding it on the shaft. Replaced the worm gear and inserted the pin that hole it in place. Replaced some of the gear grease and reassembled mixer. Went very easily. No problems at all.

Watched a YouTube video to disassemble,from there went smoothly. One small piece of advice,take pictures with your smart phone during the process. Makes remembering easier.

Pulled off end cover. Used the how-to video's to show me how to remove the (3) components (watch out when it comes to removing the spring). Removed all (3) components (one issue was the black cardboard seal, which because of its age broke. Hindsight tells me that I should have purchased a replacement seal along with the (3) new parts.
Fixed the broken part of the seal with scotch tape). Installed all new parts with the help of the video's and put the cover back on. Even with the new parts, the mixer would not run. Come to find out, after I took it to an appliance repair person, that someone had pulled both brushes and put them back in improperly. I could not find a how-to video that showed me how to de-install/re-install the brushes properly. I assume that was because new brushes were no longer available for purchase. At any rate, when the brushes were put in properly, everything worked. The repair person also adjusted the (2) screws on the speed control plate so that when you change the speeds via the lever, it all works properly. I didn't find a how-to video covering those adjustments either.

Looked for the probable cause from a U-tube video, then found the parts list and repair video on the PartSelect website. When the parts arrived within 3days the shipped email had a video on exactly how to complete the repair. Repair video was very well done and easy to follow.

Looked at the mixer schematic form your website,which made it easy for me to take it apart. Once it was apart & all the grease removed I disassembled & cleaned all the drive parts. Saw what was warn, ordered the parts from you. Three days later received the parts, everything fit perfect. Added grease,assembled the mixer and it ran perfect, good for another 20 yrs. Thank you for making it so easy to repair an old mixer in just over two hours. Rolf

Just twisted it in to place. Parts Select was awesome! Thank you!

This is the tightening screw that holds the attachments into the motor unit of the mixer. Found your web site and reordered 2 replacement pieces (in case one breaks!). Very EZ and user friendly. Thank you!

Place Pin in hole where it was missing then gently tap pin into place
Run a test and all is good ??
make sure to use a drift pin set
