Initially I thought this was due to worn motor brushes. I replaced the brushes but it did not fix the problem. Stator tested OK with an ohmmeter so I figured it was the armature part #PS3651001. Ordered that next and that fixed the problem. Spent 25 dollars which beats buying a new one. Next time I'm buying a used one from the 60s or 70s when they made them better! One tip - I had a hard time removing the pin that you need to remove the helical gear. Heating it with a heat gun helped a lot, also helped with replacing it after.

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."

I removed the screws on the back and base of the mixer. Took off the retaining ring and screws holding the mixer beater bar. Tapped out the retaining pin using an allen wrench and hammer. Carefully as not to scratch the unit. Removed the old grease, the screws holding in the worn worm gear. Replaced the gear, re-greased and reassembled the unit. To line up the retaining pin I used a very small allen wrench to get through the hole as it needed to set down all the way. Then when I wiggled it down it lined up the hole for the retaining pin. I tapped the pin back in place with the hammer and a larger allen wrench. Replaced the screws, lightly greased the gears. I had taken the "brushes" out earlier and learned that they go in a certain way. I also learned that the screw at the back by the wires, by adjusting it tighter or looser controls the speed lever. If your mixer won't work on low speed the screw has to be adjusted!

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

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

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.

worn teflon worm gear

  • Customer: Frank from Bethlehem PA
  • Difficulty: Really easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Pliers, Screw drivers

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.

Corroded speed control plate ( full of flour). Had used the mixer for grinding deer meat and lost the slow speed. Flour would fly up in my wife's face.

I just thought there had to be a way to replace a component to correct the speed problem. I've never worked on a mixer before, so I thought it would be a challenge. Actually the repair was fairly easy. Make sure the unit is unplugged from AC. I removed the back motor cover with one screw and removed the end seal. I compared the parts on the mixer with the diagram provided at the Part Select website. I then ordered the parts. When the parts arrived 3 days later, I removed the Speed Control Plate ( 3 screws) and Phase Control Bd (1 screw) as one Assy. Removed the old Governor and slipped on the new one. Assy the new Speed Control Plate and Phase Control Bd comparing wiring and screwed them back to the unit. Removed the two motor bushes by unscrewing the side black motor brush holders and inserting the new brushes. I tried powering motor and nothing happened. I thought, great, now what did I do? I found out that you must make sure the brushes actually touch the armature otherwise the motor doesn't run. The gears are worn from grinding to much deer meat and my wife says no more. I've ordered new gears and looks like that job, too, will be easy to repair. Adding these parts is alot cheaper than buying a new unit and it will run like new. Not bad for over 10 years of usage.
