How much grease should I pack into a gear box of a food mixer? should all cogs be covered?

A white or clear lithium grease. Do not cake it on but enough to get into all of the cogs/worm gears.

Leaking oil is caused by the grease in the gear box separating. This often happens when the mixer is not used much and the grease is not kept mixed by the moving gears. The solution is two-fold. First run the machine more frequently. Second is to open the head and replace the old grease with an approved food-grade grease (6 oz. is the right amount). KitchenAid grease can be found online and at Ebay. The Service Manual can be found at:

While the Artisan series is not specifically referenced, the procedures are the same.

You can also take the mixer and manual to a competent repair person.

The problem you are describing if I follow right I take the grease hole plugs out take the two spanner nuts off the man shaft and the driven shaft stick gear puller jaws into grease hole and put the gear puller onthe center saft and gently raise the top case.

its gear oil from the gear box that the motor turns to make the beaters turn,you need to replace the seals or keep adding food grade oil before you dry out the gearbox and ruin it

Hi. Lubrication of the planetary is essential for your mixer. If you're still under warranty (1 year) call Kitchenaid for a replacement mixer but don't tell them that you disassembled anything.

If out of warranty, locate Chevron FM ALC EP-2 food grade grease for your mixer AND the planetary.
If you haven't already done so, go to kitchenaid.com, click on customer care, then click on manuals search. Enter your full model # in the search window and locate the parts list for you mixer. Download it, it will assist you with your servicing and will have all the part numbers for your mixer. If you need a new trans housing insist that it be METAL!

I would also remove the transmission cover, inspect it for cracks if it's one of the cheap plastic housings. If you find cracks, you have more problems with potential internal damage caused by these cracks as this housing supports two important gears and shafts. When it fails these gears skip and cause damage to the gear cogs and bearings. Kitchenaid's replacement housing is made of metal. Hopefully all you need is the planetary greased.

Depending how old the mixer is they used to use oil,now they use grease.Regardless it sounds like a seal is worn.Where is it leaking from?

You can put in a all purpose grease. I use MOBIL 1 Synthetic Grease (RED IN COLOR) and it works fine -- you will need 3 tubs of 16oz's each tub. The cost is 30.00 or so. Make sure to get all of the old grease out and pack around each of the trans and worm shafts with the grease, then pack around the MOTOR GEAR and then put all back together. While running it make sure you can see the grease and hear the noise of the mixer through the 2 caps that are FILL caps on the head of the mixer. ALSO, you will find that you will lose 1st gear IF you have tigtened down too much on the LOCK nut, SOOOO loosen in small increments until all 3 gears are perfect and strong. ALSO, the key to noise adjustment is to Tighten (WHILE MIXER IS RUNNING) slowly the large nut that controls pressure on the worm transmission. The general rule with tigtening this nut is to tighten it till it will not tighten and then back off the nut -- IF the unit when starting does not run or it seems bound up when you first turn it back on, THEN you have tightened it TOO MUCH, SOOO back it off again (loosen it) until it starts smoothly and when you turn the mixer OFF it should come to a slow stop and not abruptly stop the mixer. Hope this helps some of you out there trying to do your own adjustments --

Hi. The oil you see used to be mixed into the grease base. It's time to change the grease in your mixer. Remove the silver band, Remove the top cover. Remove the transmission cover. Clean out the transmission, remove all grease and oil. Replace with Chevron FM ALC EP-2 grease. This grease is an edible food grade..

Remove the planetary gear, clean and re-grease. If this solution has assisted you, please rate it. ricardok45

This kind of unit are lubricated with grase paste. If the unit stays inactive for a long time, or if the motor and gears are overheating the grease paste gets melted into thin oil, and that will cause the leak.
The oil leak is usually coming from the gear box inside the appliance.
To fix the problem the unit must be taken apart, and cleaned. After this step, there is need to spread again the grease, using special foodsafe grease paste.
Disassemblying the gear box is not that easy, you will need previous experience and a gear puller to do the job properly and safely.
This appliances are also held with security screws to prevent the users from taking apart the unit, and can only be disassembled using a Security screwdriver tip.

The grease can be purchased here, check at the bottom of the page: Kenwood chef food mixer Grease.
