While kneading dough, my 27-yo stand mixer walked off the counter, and shortly thereafter the plastic bowl lift arm piece broke. After a quick internet search I ordered the part. Installation was extremely easy. 1) Using a rachet with a #3 Phillips head bit, remove the four screws holding the motor to the base. 2) Using the Roll Pin Punch pop out the roll pin. 3) Loosen and remove the cotter pin with the screwdriver and pliers. 4) Remove the broken piece. 5) Attach the replacement piece to the handle and insert the roll pin, tapping into place with the Roll Pin Punch. 5) Attach the lift arm to the piece and fix with the cotter pin. 6) Reattach the motor to the base. Ready for 27 more years of stand mixing duty!

Rather than duplicate previous repair works, I recommend going to this user site and follow their instructions: http://www.neilcrockett.com/mixer1.htm. Once you have done this repair, taking the unit apart is easier to perform this tasks. Order replacement Grease "Benalene 930-2" in the 3.3 oz container and be sure to use the full container to lather all around all the gear components so grease will be available to units for years to come due to heat build up under load. Too, the 3.5 oz container is made for one unit repair job and is available through Amazon. This grease is available on larger quantities if needed / desired. I did order both, a Worm Gear and the Worm Gear and Bracket as I wasn't sure of my mechanical ability to make this repair until I got inside the unit but the worm gear is easily replaced once you clean out all the old grease. The worm gear is a neoprene type gear with all other gears being metal. I assume neoprene is used as sacrificial to save other gears from breaking under loads and years of use.

Used the diagram on the website and a video
Totally worked!

Easily took apart and replaced gears. thanks

dis-assemble, replace part, re-lube, reassemble, test good.

disasembled found stripped gesr assembly ordered and replaced went very smoothly. It would have been good to have info and acsess to the correct gear grease to use in a mixer / food grade but it worked out well anyway.shipping was very fast thanks

Followed the repair instructions from the manual. ...

I did notice that the replacement part had an extension on it that allowed for the gear grease to be "pulled up" onto the drive gear ( the one that broke), while the unit is running. This feature was not on the original part, but was obviously an upgrade design which was added after my particular mixer was made. I think that the extension on the bracket will help prevent the new nylon gear from binding and stripping as we use the mixer from now on.

I'm glad that PartSelect had the more modern part on hand, and not just an "overstock" from the original, inferior design.

replaced worm gear and wonderd why they used plastic instead of a stronger metal gear, unit works fine

Disassembled gear housing and replaced worm gear/bracket assembly. The hardest part was cleaning and working around what looked like 2 pound of grease. I will contact you again if I need parts for anything. Thanks.

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.

Replaced gasket and O-ring. Problem solved. POC (Piece of Cake).
