The worm gear driven by the motor stripped due to excessive load.
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.
and I thought replacing the hinge pin would fix it, I used an awl to push out the old pin then used the new pin to push the old one all the way out. That did not fix the problem. Went to a store to look over a new one and saw that the screw under the head at the hinge point on the new machines was not screwed in tight. Turns out that screw is the "bumper" for the head against the neck, so the head is held back by the screw. FIXED
Worn spring would not allow atthing mixer attacments
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.
it was a kitchen aid dough mixer, had to take the top portion off and replace the assembly with a new one that holds the teflon gear. You can purchace the gear only and it becomes less expensive, but at the time I didn't take the chance cause the greese was there and didn't want to take a chance. Its a simple repair by removing some cotter pins and phillips head screws.
the plastic covering the thumb screw cracked almost half way and lost the piece....so the new one is being used to replace this old one...very easy to install
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.
