KSM150PSQG5 KitchenAid Mixer - Instructions

I found a video on how to repair mixer that would not turn. Watched video several times and replaced worn worm gear. Getting the old worm gear was the most difficult part of the job. I had to go purchase a pin punch ($5.50) with the correct tool is was easy.

Unscrew and dismounted the mixer, gather all pieces and screws, cleaned and washed every part, took away the old grease and replaced it with a new one, also looked carefully for the lost teeth and found them, Put grease in every part, put back and screwed all the pieces of the mixer, then tried the mixer which worked really well.

followed the instruction on you tube

My husband looked at youtube to figure out what the issue was. He saw a video that identified that the likely problem was the worm gear. My husband took the kitchenaid applicance apart, as he saw in the video. We ordered the part, it took less than a week to arrive. He rewatched the video that demonstrated how to put the kitchenaid mixer back together. It's a bit messy due to all the packing grease, but a pair of nitrile gloves, paper towels, and an old rag help. We put a garbage bag over the appliance after it was taken apart to protect it from any dust and my curious cat. We let the kitchenaid cycle for about a minute to make sure the gear was greased. I haven't used it to make bread yet, but I'll do that soon. Thanks for supplying the part that saved us at least one hundred dollars and TRY to get a person who will repair small appliances.

Per a video on this site, I removed the stand part, then removed the rear electrical cover and aluminum band which wraps around the mixer. Next, remove the drip ring and planetary gear (use a punch). Then remove the 4 screws securing the bottom housing and the 5 screws around the planetary gear housing. You should be able to pull the upper and bottom housings apart now. This exposes the control lever. Just unscrew it and replace it. Re-install all parts in reverse order.

Repair was easy. Remove the seal ring with a flat blade screwdriver and drive out retaining pin. Pry out lower unit using two screwdrivers, one on each side. Once apart, use spring clip pliers to remove snap ring. Pull out shaft and replace. Clean and lubricate as you reassemble in reverse. Google the model number to get detailed instructions.

I was very happy with the customer services department and the support I received in identifying the part I needed for the repair. I received an email confirming my order with all details. I do wish you had a more cost effective shipping alternative, like Priority mail.
The repair went well and the mixer is back in business, for making those Chocolate Chip Cookie and brownies if you know what I mean.

Thank you

1. Removed the mixer from the base by removeing the pivot pin at the mixer base support. 2. removed the retainer ring from the housing. 3. removed the pin from the shaft. 4. removed 5 philips machine screws from the round base. 5. removed the round base from the mixer housing. 6. removed the o-ring from the shaft. 7. removed the shaft and large worm/pinion gear from the shaft. 8. pressed out the pinion drive gear from the mixer. The reverse operation repaired the mixer to new condition.

Order part through parts select. it only took 3 days to receive part. The mixer was very easy to take apart and to replace the gear. it was back together in about 20 min. The video from kitchen aid to repair the unit is awsome. Thanks

Remove the mixer head from the base by removing the 4 Phillips head screws. Pry off the ring around the rotating part with a flat head screwdriver. Punch out the pin holding the rotating part and remove. Remove the trim strip by removing the two Phillips screws at the rear of the unit. Remove the 4 screws at the bottom of the mixer head. Carefully separate the bottom of the head from the top using a flat screw driver. There will be the power wires connecting the top to the bottom of the unit. It is best to disconnect these wires to avoid breaking them during rest of the procedure. There will be a lot of grease in the gear box of the mixer. The assembly holding the damaged worm gear can now be removed by removing the three screws holding it to the bottom of the mixer head. At this point I removed the grease from the worm gear assembly to allow better inspection. Punch out the pin holding the worm gear to its shaft and remove the shaft. The worm gear is now free and can be replaced. Add some extra grease to the new gear and reassemble the mixer in the reverse order.

After removing one screw at the top of the rear housing, and the housing you have clear access to the wire attachment points. I useg a very small screw drive to unlock the female disconnects from the male connectors.I disconnected and connected the wires one at a time to be certain I did not misconnect the wires. The ground wire is attached with a screw. The moulded strain releif is pushed onto the main housing cutout and the rear housing tabs slip into pockets at the bottom of the main housing. The screw at the top holds it is place.

Replaced gears and cleaned and re-greased gears

I removed the cover off the back of the mixer. Carefully remove the cardboard gasket around the outside edge. Unlock the nuts that hold the two adjusting screws. Count the turns to remove each screw in order to keep the right adjustment. Pull the plate away enough to remove the control board. There is one long and one short wire that gets plugged into each side of the plate. Watch the location of each wire to make the right connection. Reattach the screws to the proper position. Then install the gasket and rear cover. Check for proper operation.

watched instruction video (from Part Select), the demonstration was close enough to enable me to repair the mixer. Newer mixers are disassembled differently.

Unscrewed 3 Philips screws. Pried out the old screw cap. It had been there for 25 years and had flour, egg, etc. build up over the years. Did use a needle nose plier to lift it out. Put in the new one. Needed a rubber mallet to snug it down. Design has changed slightly over the years. Put the 3 screws back in and as they say in England, "you have an uncle named Bob."
