Lubricant leaking from planetary gear

To remove the planetary you knock the silver pin out with a punch. There is no 'oil' as such in the machine. Sure it is oil but it is breaking down out of the grease. It is harmless and food grade so nothing to worry about. The grease should not have got to the point it needs replacing until it is about 5 years old. I would remove the planetary and wipe the shaft clean and any excess inside the planetary remembering that you do need to leave some lubrication on the gear teeth in there.

Grease inside the Planetary Assembly (the shaft is tight fit to the Planetary
plate at the factory and is not designed to be taken apart, so do not use
any hard object such as a screwdriver to separate them) over times can
turn to liquid and leak down the bowl. Removing the Planetary assembly
and adding Kitchenaid Food Grade Grease is not a task for a novice.
To properly remove the Planetary Assembly, you must work from inside
the Transmission Housing: Remove in this order: Retaining Clip(25), Bevel Gear(21),
Retaining Pin(18), Worm Follower Gear(19). Use a soft mallet to tap out the Shaft
of the Planetary Assembly(15). Re-assemble it in the reverse order.
Note: The Bevel Gear is extremely tightly fit on the shaft, and a pin punch
must be used to remove from the shaft.

I came across a manual for a Blakeslee f-40 60 80 and here is what it said. Hope this helps

Lubrication
The planetary and spiral-beveled gears are self-lubricated for life. The lubrication used is micromly grease and must be re-applied if gears are replaced. The transmission uses Mobil "delvic 1" synthetic oil which should last the normal life of the mixer. No lubrication is required for the auxiliary drive hub.
If lubrication is applied to the auxiliary hub a grease-like substance will possibly leak out causing damage to the product.
Applications of any lubrication will Void Warranty.

Hi,

It sounds like the Planetary Gear assy. has gear lubricant leaking into it from the gear case above it. This may not be that unusual so there may be 2 possibilities or a combination of both. The Gear Case is directly above the Planetary Gear assy. It is filled (sort of) with a food grade (assuming...I hope) grease that is necessary to keep things lubed. There are fiber washers and possibly an o-ring in the shaft assembly which should keep the grease from migrating toward your food. The Planetary Gear assy. is the part that rotates around on the business end of the mixer. It has a bronze bearing that is intended to run without lubrication. However it is a wear point and if worn sufficiently, could allow escape lubricant from the gear case above to drip into your mix. The Kitchen Aid Service Manual is a good source of info. You can get it as well as complete diagrams of the internal parts at:

I know if it was my mixer, I'd give it a look. They're good tools and worth the effort!

Good luck.

Your kitchenaid mixer is meant to leak a tiny amount of oil around the rim of the planetary gear on the front of the machine. This is just a means of lubrication. If however you are getting alot of oil coming out of the sides of the unit, the transmission gasket may be worn or broken if this is the case it will have to be replaced. part number for the gasket is 4162324. If your getting alot of oil from the center of the unit this could indicate worn or broken seals. there are 4 located inside the unit, and would need to be dismantled in order to replace. part number for all four is 3180163. If you are leaking alot of oil or grease continued use of the mixer might cause it damage. Hope this helps

Thanks

The transmission center shaft seal/chimney is bad.You need to tear the transmission down in order to repair,let me know.

Hi. Your mixer needs to be serviced, have old grease and oil removed, parts cleaned, then re assembled with new grease. Remove the tapered-pin from the planetary gear, remove planetary gear, clean lubricate and re install. Chevron FM ALC EP-2 is a "Food Grade" lubricant, meaning that it's safe for human consumption if it accidentally gets into food. There are no seals, only bushings. The existing bushings will hold back the new grease. The oil has separated from the base of the grease. If you don't use your mixer very often, start it up about once a week to keep the grease properly mixed.

If you'd like more info on your mixer goto kitchenaid.com, look up your model # download the PARTS drawings. Use these drawings to re-assemble and to determine if you need any replacement parts. Be prepared to wait at least a month for your parts to arrive.

Hi. The grease that your mixers are lubricated with has reached a stage where the oil is leaching away from the grease. All your machines need this grease changed. Shell Darina EP-2 or Chevron FM ALC EP-2. These machines need to be internally cleaned and re-greased. It's important to remove the oil from any place that it drips. The planetary gear must be removed, cleaned and re-greased also. It's a messy job, but you can do it yourself if you're familiar enough with machinery. If not, then a suitable service outlet can easily do it.

If you choose to do it, go to the Kitchenaid website and locate the parts files for your particular model, these drawings will assist greatly with the project. If you can, take digital photos at every step of dis-assembly as a reference for re-assembly. If this solution assists you, please rate it. Good luck! ricardok45

Leaking of oil in a stand mixer is not necessarily indicative of a large problem.

Kitchenaid stand mixers are overpacked with oil to last the lifetime of the motor. If the motor sits idle for some time (is not used), the oil may begin to drip from the gears and settle. Oil leakage may primarily be seen from around the beater shaft or planetary action.

A stand mixer can lose up to a 1/4 cup of oil before it needs to be serviced.

It is recommended to run the mixer on speed 10 for 2 minutes in order to redistribute oil back into the motor. In order to prevent future occurences, this is recommended to be done every 3 weeks if mixer is not being used.
Exploded parts views for all mixers are available at www.kithchenaid.com. Click "Customer Care" in the upper right hand corner of the main page, and then select "Locate Manuals and Guides." You will need to enter the unit's model number exactly as it appears on the bottom of the mixer. It will be listed on a white sticker.

Thanks,, great info..

I took mine all apart and the oil was just at the point of turning into grease. Nasty,, brown smelling ****.... I cleaned it all up and just used a sync 50w gear oil.. I over filled it and the extra ran out of the motor end of the gear box... It might have been about 2 table spoons too much.. Now it does not leak anymore.

Thanks again,, jaybeesee
