Hobart N50 / KitchenAid Model G: how do i remove planetary?

Hi, i saw that you were a Hobart tech for a long time. i have a KitchenAid Model G which was made by Hobart and is identical to an old N50. this one is about 1938 vintage. it needs cleaning up and new grease but i cant get the planetary assembly off. i removed the ring and then the shaft pin but the planetary doesnt want to come off the shaft like it does for current model KitchenAid mixers. is the planetary assembly just stuck on the shaft for sitting all these years or is there something else i need to remove first? thanks in advance, dan 925-672-2143

Hobart N50 noises


The frequency is the same in all gears.
disconnect the power and invert the mixer and remove the planetary after driving out the taper pin, then you can access the transmission. It may be a rotor shaft bearing in the motor or no grease on the worm gears.
Nice touch with the video.

My hobart n50 runs on the same speed in 1 and 2 and will not engage in 3 .. also sounds louder than normal..how do you lube?


Hello Ldl,

I understand that you are having a problem with you 5 quart commercial mixer by hobart. The 1 and 2 are the same speed and you are not getting 3. You also would like to know what oil to use in your machine and how to fill the unit.

To answer you speed question first. The speed is adjusted by the bolt located in the middle of the planetary (the part that turns underneath of the head the attachments hook to). If this bolt is tightened all the way up or to lose it will not allow you to achieve all of the speeds. You will have to adjust this screw many times and turn the machine on to check you speeds. Eventually you will achieve all three speeds.

Before I answer how you lube the machine you need to know what kind of lube to use. The gear box uses a 90 weight gear oil and the planetary uses 140 weight gear oil (grease).

Lubing the gear box with top cover:
1. Remove the top of the gear box (the cover)
2. There is a Round plate with three bolts (do not remove) in this plate there is a disc (looks like a cap seal) use a small screw driver to pry this disc out carefully you will have to put it back once you are done lubing the unit.
Lubing with out a top cover:
1. Remove the switch and gear selector (remember position of gear selector)
2. Fill thru whole in side behind plate removed

Lubing planitary:
1. Remove drip ring
2. Remove the planetary (unscrew bolt in middle)
3. Remove key located in the side of shaft
4. Lube and put back together

Hobart N-50 Mixer beater attachment spins but has no resistance


Sounds like the shear pin on the planetary shaft has sheared off. Has the mixer been subjected to a heavy load. Remove the planetary and see if the shear pin is intact otherwise you may have to open up the transmission.

How to completely dismantle a Hobart N50 or KitchenAid Model G


If you only want to service the unit and not open the case, you can add grease through the gear shifter plate opening once you remove it. if you have a grease gun with a flex nozzle that's a bonus.
If not it is a messy job. Keep lots of paper towels at hand and use a narrow spatula to get the grease inside. Get as much in as you possibly can.

To remove planetary, with pin removed, spray a bit of wd-40 or other penetrating oil into where the pin came out of let it penetrate for a few minutes. Plan-A Take two screwdrivers and gently try to pry the planetary away from the body of the mixer. Plan-B Add a bit more lubricant to the shaft pin area and install a beater, then try prying with one screwdriver while putting downward pressure on the beater, alternate prying on both sides of planetary. Excessive force at the planetary top can/will crack it as it is a molded piece of metal. If you found this solution helpfull, please rate it. Good luck.

New (old) N50 ML-4749


You should be able to purchase the manual. I know that Hobart abandoned that policy a few years back -- unless they re-instated it. Call Mother Hobart and ask. 937-332-3000

There is a few tricks to these units, it would be tough to convey here. But here goes...

Remove back cover. Loosen 6 or 7 screws around outside of motor windings. Thump the nose of the mixer downward to break the seal. Watch for spacer washers where shafts go into motor case. Remove spring. Remove idler. Remove shifting guide. Remove gear assy. Leave beveled gears in place if possible. Clean. Use Darina II grease. (20 oz) Clean and permatex "seal". Tighten mounting bolts. Adjust set screw at back of planetary. (Double set screw. The first one is to lock the adjustment.) Test in 1st and then 3rd while turning the set screw. You just make it quiet for a proper adjustment.

Good luck -- Mike

Noisy Hobart N50 Mixer


First, there is a double set screw (one on top of the other - if they are both there) towards the back of the planetary.

Remove the first screw, it should have a normal tip, not pointy. Run the mixer in 1st and adjust the screw, first out then in. Then repeat in 3rd. You should clearly hear a difference.

If not, you probably need to repack the grease in the transmission. The proper grease is called "Darina II". It's expensive ~ $35 per mixer.

Hobart N50 Tripped


The reset button is to protect over amping the motor. The N-50 is not a very strong unit, (commercially), but you won't break a gear. If you overload the unit, you'll either trip the overload (reset button), or you will break the taper pin that attaches the planetary to the center shaft.

If you're looking for a small commercial unit, and you're in the US, look into the 10 qt Precision Mixer.
