At some point the planetary drive head started wanting to just drop off (fall) - like, into the mixing bowl) when operating the mixer. Why does that happen? Does something need to be replaced? Did a clip or retainer disappear? I could epoxy that drive head to the vertical shaft (the one that sticks down with MANY tiny long teeth along the shaft, but that might affect repairability long term.
quinn47 , If part not available for some reason. Just a thought! If possible and you have no alternative, is it possible to drill a hole, then thread hole and use a set screw to keep the piece in place when using and still be removable when need be. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
Pinning the shaft like this works. I pre-drilled with a .100” drill, followed by a .125” and then drove a 1/8” spring pin in flush. There is a step in the bore in the hub around the shaft. After pinning I filled this gap with JB weld to increase engagement bearing and I I put a dab of JB weld on both ends of the spring pin to resist walkout. I made sure all the parts slid well on the shaft and redistributed some grease to all the appropriate places.
The person that said Apoxy tothe top was the only one that made any sense to me. That’s what I did and I hope it works.
Here’s some pictures the job that I did on it. Was white, I took everything apart, And painted red. I try to put a pin under the planetary but didn’t work, Wasn’t much space to hit the shaft and be secure. So what I did, I put the pin on the top side. I did use a pain that I bought on Harbor Freight Tool if you decided to make the same job make sure you open up the both ands off the PIN, it will prevent the pin to come off good luck.
After cleaning the housing and shaft squeaky clean, I applied two part epoxy to the splines on the shaft and installed into housing. I let the epoxy completely cure before drilling my 1/8” hole then installing the 1/8” spring pin. In my photo you can see the epoxy squeezed out about a 1/16". This prevented the upper ring gear from fully seating where I could not install the pin through the shaft. I used a razor knife to cut the epoxy off flush and everything fit perfectly!
Thank you for asking this question, I appreciate it and all the responses. The planetary drive came off the shaft on my Kitchenaid after a busy season of making Christmas cookies. So, I bought retainer ring pliers & some JB Weld, ready to epoxy. However, while I was testing the connection between the drive & shaft, I couldn’t get the shaft back out of the drive!! I just smashed it in as far as it would go and put the mixer back together, greasing the gears for the first time in 14 years. It’s working great now, but we’ll see how long it lasts! If the drive comes off again, at least I have my JB Weld handy to glue that thing once and for all. LOL
