Noisy Hobart N50 Mixer

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.
If you need parts:

Is the planetary still off before the taper pin is in place?

It's a shot in the dark but if everything lines up, I can think of two possibilities:

1. The taper pin in backwards, and
2. The shaft hole in the planetary is out of round.

The gear has not really changed. It is a fail-safe gear designed to break before the motor is damaged by the transmission being jammed.

As to whether it will last, I can't say. I know of no other sources for the gear other than keeping a watch of Ebay.

The N50 is a heavy duty / commercial counter top mixer. It is available in several different versions for different power sources. Make sure yours is the model for use with the power available at your location. The power versions are:

100-120/60/1, 100/50/1, 230/50/1, 220/60/1 and 230/60/1

This lists the information in the following format: voltage/frequency/phase. If used in the US or Canada (and many other parts of the world) you would most likely want the 100-120/60/1 or the 230/60/1 version. All are single phase, so this shouldn't be an issue to worry about. Use of any of the other versions could result in shortened life expectancy of the mixer or immediate, catastrophic failure of the mixer and possibility of burns, shock or electrocution if connection is attempted.

If the mixer matches the power available, check for proper wiring at the source point of connection and in the mixer. You may need an electrician to change the power at the connection point from 100-120/60/1 to 230/60/1 (or vice-versa since BOTH are available in North America). Also check to be sure that fuses or circuit breakers in the electrical panel are intact and on. Do not overlook GFI outlets if using the 100 to 120/60/1 version. Reset any tripped GFI outlet. If still unable to operate, verify that power is present at the connection point. If unable to operate, contact an electrician to check the power and wiring of the mixer.

The mixer data sheet is available here.

The best solution I can give you is to become a member at the Hobart Corp. website and use there schematics to find where the pin goes. It is free to use the parts catologues have a parts blowup.

Thank you for using FixYa, I hope this helps.

Have you contacted your closest Hobart branch?

you would have to have it made not available

Some of the N50's were packed with a white grease. It tends to seperate. So the oil portion finds it's way out. It sounds like it is getting into the motor case, and is running down the inside of the column. Hobart now uses a brown clay based grease --- Darina 2.

If the amounts are small, and the mixer is not excessively noisy, I wouldn't be concerned. If you wanted to fix it, the transmission would need to be removed, cleaned, and repacked. For a Hobart tech, 3 hours labor, $45 grease, plus parts.

CE is the marking that shows its european conformant.  I think the difference is mostly in terms of the no volt interlock switch.  This means the KA style N50 bowl won't work with the CE models - too low.

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.
