Three phillips-head screws held the "Cap Screw" in place on the stand of the mixer. After cleaning the stuff out of the screw slots, the screws came out surprisingly easy. After the plate was lifted off, we cleaned the residue from under the plate, placed the new one in position and easily screwed in the 3 screws.
We were very pleased by the quick delivery of the part.

Looked at the mixer schematic form your website,which made it easy for me to take it apart. Once it was apart & all the grease removed I disassembled & cleaned all the drive parts. Saw what was warn, ordered the parts from you. Three days later received the parts, everything fit perfect. Added grease,assembled the mixer and it ran perfect, good for another 20 yrs. Thank you for making it so easy to repair an old mixer in just over two hours. Rolf

Attachments would not work, spindle turned erratically, with no power

Punched out the roll pin to remove eccentric from spindle, undid 5 screws (after removing trim ring), and removed 4 screws to undo the motor housing. Make sure to keep the one screw with a lock washer in the BACK of the housing. Undid the screw on top to remove the back of the motor housing to take out the strain relief grommet, prior to removing the motor housing. Scraped the excess grease into a tub to re-use. Pulled out the shaft, and lifted out the old (stripped) gear and plopped the new one in. Make sure to mark match points for parts, and put the pins back in in the right order. You have to put the 5 screws back in before sliding the trim ring on, and putting the roll pin back. make sure all gears mesh and test before snugging the motor housing screws. Be sure to orient the strain relief grommet securely, and be careful of the filter plates in the back of the housing (they're brittle). putting the grease back is like frosting a cake. Save a little for the planetary ass'y.
