Mixer ran way too fast at slow speeds.
‘Can’t remember well enough to describe accurately. Removed one screw to remove rear cover. Removed two screws to remove bright-metal band - probably not necessary but it did yield a bit more working space. IIRC, three screws and removing wires from spade-connectors was sufficient to remove the speed control plate. Remove one more screw to remove phase control board (probably unnecessary). I took close-up pictures with my iPhone first to assure wires would get replaced on the proper lugs (only to discover the wiring diagram later). Adjusting the control plate to meet the speed criteria in the instructions was very easy. It did serve to remind me that I probably didn’t need either of the new parts; readjusting the old speed control plate would probably have done it. But I appreciate the POM brought on by the new parts.
It’s an incredible pleasure to work on something so well-made as this old Kitchen-Aid mixer. I just enjoyed handling it! Having achieved a proper repair was rather satisfying too. I just loved the entire experience!
Replaced the speed control plate and phase control board and works well. Pay attention to speed control board spring and adjustment lever when reassembling.
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.
After 40 years, the spring latch that holds the bowl in place broke from metal fatigue. I make bread for a Farmers Market and HAD to have that part. The part arrived in less than 18 hours!!!!
I screwed the two screws into the place of original holes and Voila! it was repaired.
Mixer would slip gears under load, finally would not mix under any load
Rather than duplicate previous repair works, I recommend going to this user site and follow their instructions: http://www.neilcrockett.com/mixer1.htm. Once you have done this repair, taking the unit apart is easier to perform this tasks. Order replacement Grease "Benalene 930-2" in the 3.3 oz container and be sure to use the full container to lather all around all the gear components so grease will be available to units for years to come due to heat build up under load. Too, the 3.5 oz container is made for one unit repair job and is available through Amazon. This grease is available on larger quantities if needed / desired. I did order both, a Worm Gear and the Worm Gear and Bracket as I wasn't sure of my mechanical ability to make this repair until I got inside the unit but the worm gear is easily replaced once you clean out all the old grease. The worm gear is a neoprene type gear with all other gears being metal. I assume neoprene is used as sacrificial to save other gears from breaking under loads and years of use.
Followed the repair instructions from the manual. ...
I did notice that the replacement part had an extension on it that allowed for the gear grease to be "pulled up" onto the drive gear ( the one that broke), while the unit is running. This feature was not on the original part, but was obviously an upgrade design which was added after my particular mixer was made. I think that the extension on the bracket will help prevent the new nylon gear from binding and stripping as we use the mixer from now on.
I'm glad that PartSelect had the more modern part on hand, and not just an "overstock" from the original, inferior design.
disasembled found stripped gesr assembly ordered and replaced went very smoothly. It would have been good to have info and acsess to the correct gear grease to use in a mixer / food grade but it worked out well anyway.shipping was very fast thanks
Disassembled gear housing and replaced worm gear/bracket assembly. The hardest part was cleaning and working around what looked like 2 pound of grease. I will contact you again if I need parts for anything. Thanks.
First i went to the Kitchen Aid web site and found a video on how to take a part the mixer. Followed the instructions from the video and it was very easy. The grease in the machine was black so i cleaned it out of the transmission and repack it with hi-heat wheel bearing grease that i got from a auto parts store it took about a 1/2 lb. then put the gasket in and back together and put the o-ring on. Have run for awhile and it is ok. Want to say that these are very well built machine.
