WP240309-2 240309-2 replaces KitchenAid Replacement Gear

I have an older (~1988) KitchenAid KSM-5 Proline bowl lift model, one of the last of the ones with the Hobart engineering (has the motor brush screws on the side of the mixer head).My unit began to whine and overheat, particularly when I used higher speeds, when mixing a large batch (~1,000g) of bread dough -- perhaps the toughest job one of these mixers is subject to in home use.My dilemma was to repair or replace. After a review of more recent models, I found that an equivalent replacement to my old workhorse, relatively bullet proof KSM-5 model was a KitchenAid KSM-7 Proline, which costs ~$600, but is not as readily repairable. (In the KSM-7, if the motor or drive train gives problems, the whole motor assembly must be replaced, unlike in my KSM-5, individual gears and components can be readily removed and replaced.)Since the one, which I had seemed to be overall of better build and service quality, and is much quieter in operation than KitchenAid 5 qt models commonly available in membership and big box stores, I decided that repair, if possible, was the best course.Though the motor and other features have changed a lot after Hobart sold the KitchenAid line in the early 1900s, this part fit mine perfectly and restored it to almost as good as new operation.Some disassembly and assembly is required to install. Clean out any and all old grease along with any worn bits of metal or plastic from the old gears. Thoroughly repack all the gears in the forward portion of the housing with a heavy grease such as "Food Grade Grease & Gasket by Ohoho - Compatible With Kitchen Stand Mixer," or "Impresa Products 4 Oz Food Grade Grease for Stand Mixer Universally Compatible."

perfect fit.

works great

My kitchenAid stopped spinning and I had a feeling it was the nylon gear. Luckily my dough was done kneading. I opened up my mixer with the help of some online videos and sure enough it was the nylon gear. I went with the whole mechanism. It’s a perfect match and works like the first day I purchased this mixer 24 years ago. After putting it back together with new grease I tried adjusting the speed control and it broke at the screw mounting. I ordered a new speed controller from the same vendor and my mixer is running brand new. These two fixes saved me from having to buy a new mixer.

The part fit great once you figure out how to get the machine apart to replace it

Perfect fit for my Artisan mixer.Comes dry, you will have to grease it yourself. Easy to drift out the pin when it's clean and new and not already mounted in the mixer. Grease both sides of the washers, pack the gear teeth with grease, grease the shafts and their holes. Put it back together using a finishing nail to line things up at the pin hole, then gently tap the drift pin in until centered. Mount it to the mixer, then coat it with lots more grease. I learned the hard way that you're better off with a factory part and not a knock off, and you absolutely want the proper kind of black grease not the white food grade grease ever.

I'm on my second of these; the first one lasted a few months and burnt out on some really dense pasta dough. I'm considering that my fault, but if this one burns out quickly too I'll revise my rating. I've replaced just the worm drive itself in years past, and it's so much quicker and easier just to swap in the whole tower like this.

My K5SS began to skip and fail after over 39 years of dutiful service. As I suspected it was the principal transmission gear that was at fault with some of the gear teeth missing. Ordered this part to replace the tower. Fit perfectly and after applying some food safe grease, turned on and was back in service. Looking forward to continued utility with the ‘built like a tank’ KitchenAid!
