SOURCE: KitchenAid KPRA Brass input shaft sheared. Need a replacement

The "brass input shaft" is designed to break in the event of too much torque being applied; it acts as a shear pin. For safety considerations, I would be careful what I used to replace the shear bolt/shaft. Failure of the shear bolt is necessary to prevent more serious damage to either: 1) the mixer, 2) the pasta attachment, and perhaps most importantly 3) the object stuck in the pasta attachment (think of ingested clothing, hair, fingers, etc). Unfortunately, KitchenAid refuses to supply replacement shear bolts (and I couldn't get an answer as to why); however, they seem pretty good about replacing the attachment under warranty. But logic dictates that a part, such as a shear pin, that is designed to fail, will have a high probability of breaking long after the warranty period has expired. To that end, I have machined a bunch of spare shear bolts to the same physical dimensions as the original part out of 5/16" brass hex stock. I would consider making some available to others in need at a nominal fee.

Runs but doesn't turn. Worm gear is not broken.


Something must be broken if the motor is turning and the planetary is not. It will be one of the following, we will start from the first point of contact with the armature
1) Worm gear broken (fuse gear) you say no teeth broken
2) Worm gear not broken but whole unbroken plastic part not gripping aluminium boss
3) Pin through worm gear broken or missing
4) Pin through centre (or bevel) gear broken or missing
5) Pin through small gear in planetary broken or missing
6) Pin through planetary hub centre shaft broken or missing

The most common ones in order of likelihood are, 1, 2, 3 and 6

Broken input shaft


KitchenAid doesn't sell any internal parts for the KitchenAid pasta attachments, the only thing to do is buy a replacement, if it is just the pasta roller you can purchase the KPSA, if not the others are just sold in the KPRA pack

Kitchenaid Mixer Planetary becomes sluggish when met with resistance.


The problem will be with the worm gear, if the gear is not stripped then check that the locating pin for the worm gear is not broken or missing. Occasionally the plastic gear can detach from the aluminium boss between plastic and shaft. The worm gear is the 99.9% place where drive can slip. Afterthought, I suppose the planetary pin is not missing or broken??

Do th gears in a kitchenaid mixer need oil


Hi SHIRLAFINK, you do not need to 'oil' the transmission gears on a KA mixer. Your KA mixer comes with enough grease to 'last a lifetime' - whatever that means?

Depending on the age of your mixer and how heavily you use it, there may be a time when you might want to replace the grease, but that period is usually measured in years of useage.

Of course if one of the gears strips or breaks, you will need to replace all the grease when you replace the broken gear. Attempting to use salvaged grease jeopardized the remaining gears if pieces of metal or plastic debris are suspended in the old grease.

Mixer has a broken gear or tooth in the head.


Hi. You have experienced the problem that many hundreds of kitchenaid mixer owners have. No doubt your mixer began having problems while you were mixing bread or cookie dough. Kitchenaid advertises that these mixers can handle these types of dough, the brutal truth is they cannot, for one very important reason. The cheap plastic transmission housing has failed, and as a result has caused damage to your mixer's transmission.

This cheap plastic part supports two of the most important shafts and gears in your mixer and has no business being installed in a high priced mixer. Heavy doughs place enormous stresses on these gears and shafts and this plastic part is not up to the task, Kitchenaid knows this of course, but refuses to issue a recall notice.

If your mixer is still covered by warranty, call Kitchenaid's so-called customer satisfaction dept. and demand a mixer replacement with a METAL transmission housing.

If out of warranty, unplug the mixer and don't use it. Remove the silver band from around the head of the mixer, then remove the four screws that secure the cover, remove it. At the front top of the mixer locate the transmission cover, if it's made of a shiny metal, you're in luck. If it's made of plastic, examine it carefully for cracks around the mounting screws or anywhere else on the housing. If you find cracks, you have found the culprit that has caused untold internal damage to yoúr mixer

If you are up to the task of repairing it, go to the kitchenaid.com website and do a search for your model's parts catalog. Download it, it will help with the disassembly and reassembly of the mixer.

You'll need to remove virtually all of the old grease. Remove the trans. components and wipe them clean, in order to correctly assess damage. When you determine which parts need replacement, you must insist on a metal housing when ordering parts. Try mendingshed.com for parts. You can also order parts from Kitchenaid...Just be prepared to wait at least a month for them to arrive from Kitchenaid! "For the Way It's Made"?

Finally regrease with Chevron FM ALC EP-2 a Food Grade lube.

Be sure to tell the people at Kitchenaid what you think of their cheap plastic housing!

If this solution has assisted you, please rate it. Good luck! ricardok45
