KSM103RB KitchenAid Mixer - Instructions

Easily took apart and replaced gears. thanks

just as the you tube instructions said.

I rip everything apart and put new and grease it. works like a new one.

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

Easy

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.

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.

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

Simply removed damaged gears. Very simple to do. Ordered gears. Replaced gears. Both working well ( so far. ) Machines are easy to dismantle. Just be sure to put the screws back in the holes you took them out of when dismantling...no lost screws. On the smaller model, took pictures of the wire positions to be sure they were replaced in the proper order. Larger model had no wires to remove.

Went to partselect, found model number, printed blow-up of mixer. Figured out disassenbly procedure. Drove out main pin removing mixer head from stand. Save pin. Drove out pin in mixer main shaft which allowed planetary head to be removed. Save pin.
Removed stainless steel bezel to expose screws for removal of bottom half of mixer body. Removed screws and carefully separated mixer halves using two screwdrivers as prybars. Care must be exercised to prevent chipping of paint on body.
Separated body. cleaned grease from gears to find actual problem. Removed broken geartooth and grease near broken part to make sure no small broken chips remained. Removed pinion shaft assembly, drove pin from gear releasing broken pinion/shaft. Save pin/
Cleaned grease from pinion shaft assembly using mineral spirits and a small brush to reveal how part could be disassembled. Ordered part immediately on-line. Part arrived 1 business day after it was ordered.
Reversed process for replacing pinion shaft. Applied fresh grease obtained from excess already in mixer, spun pinion shaft to make sure grease was properly distributed. Reinstalled pinion shaft assembly. CAREFULLY plugged in mixer and jogged motor to make sure all was free and that mixer worked. If you can repair this mixer, you should have enough sense to do this diagonistic. Keep fingers away from all moving parts, don't touch expposed electric wires. Plug in only after making sure switch is in off position. Jog using mixer switch. Make sure mechanism is free.
Complete re-assembly by following blow-up and reversing disassembly steps. It may be good to write down you disassemblly procedure if it is possible that you won't be reassembling within a day or two.

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

Unscrewed the existing screw cap, put the new one in place, replaced the screws. So easy!

With a screw driver remove the screws holding the old base in place. With a flat head screw driver carefully pry and remove old mixer base. With 600 grit sandpaper clean and make smooth any burrs or rough spots in the mixer base recessed area. You can use some light grease and coat the outer edges of new mixer base and place in the now cleaned mixer base recessed area. The new base maybe a tight fit and not be fully seated in the recess. If a tight fit, place the piece of 2x4 piece of wood over the new part that is in the recess and carefully tap the base home using the sledge hammer. Check to see, if the base is fully seated. If not fully seated, tap again When fully seated replace the screws. You may have to adjust the height of the stand mixer head with mixer paddle attached for proper clearance between bowl and paddle. See your mixer manual for adjustment procedure

I replaced the phase control board because the mixer had only
one speed and was surging. I noticed from other posts that it
is important to note the setting of the speed plate before you
remove it in order to remove the phase control board. Also be
careful removing the associated 'slip-on' terminals as it would
be easy to damage the speed plate. If I ever do this again I
will go ahead and replace the speed plate, probably the cheapest
item to replace. The operation was a success and the mixer is
back in business. Thanks.
