Question about Hobart N50 Stand Mixer

1 Answer

N50 with loud noise in operation

We obtained the N 50 used from a company that used it to mix trial mixes of product. It has been loud since we received it. We took it to an authorized service center for repair. The service center lubricated it and charged $400.00, the noise was back within a week. We are extremely pleased with the operation of this machine, we only wish we could be in the same room while it operates! My question is two part, 1. is there a parts breakdown available for this machine and 2. is it worth my time to dismantle it myself and replace the bearings, seals, and inspect the gears. (This is what I requested when I sent it in to the service center). Thanks for your assistance.

My Kitchenaid mdl: KSM 155gbca is making a loud bumping noise with or without an attachment.

It is more than likely in the planetary or the fuse gear inside the gear box. Try it once you have the planetary off before you go looking inside the gear box. Easiest is planetary problem but far far more likely is the fuse gear.

My hobart n50 mixer,when pluged in does nothing at all. why? and what to do?

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.

Ibought a hobart n 50 mixer took it oversaes used a 700 watt step down transformer to work it but after a few minutes it over heats is there a certain trans former to be used for it thank you

Assuming the mixer is overheating (and not the transformer), first check (with a multimeter) the voltage being supplied to the mixer from the transformer and ensure it is near 120V. Next, do you know the powerline frequency in the country you're in? The mixer (assuming it came from US) was designed for 60Hz US power. Many other countries use 50Hz, which could cause overheating if the mixer is used heavily. When 60Hz equipment is used on 50Hz power, it normally must be "derated" meaning it must be "underworked" as compared to its original capabilities.

Be sure to test the voltage going to the mixer, from the transformer, not only when the mixer is off, but be certain to test it in use, mixing whatever it is you are mixing -bottom line is to be sure the transformer continues to output 120V under load, with the mixer loading the transformer.

If all is OK with the power going to the mixer, then the problem is either in the mixer or the problem is how it is being used. What are you mixing with it - are you overworking the mixer? Does the mixer always overheat or only with particularly demanding jobs (cut down batch size in this case). What gear are you mixing in? If overheating in second gear, try mixing the same batch in first gear. If you have or can find a user's manual, it probably gives reccommended batch sizes for various typical products you might mix, be sure to follow these recommendations and "derate" for 50Hz if necessary.

It's possible the motor is weak from a long life spent working hard. A weak motor will draw excessive current and overheat. Where is the mixer hottest? The front at the gearbox/transmission or the rear where the motor is located? Maybe the transmission is lacking lubracation and needs a grease change. There a many possibilities for your mixer to overheat, and I hope this helps.

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.

May need lubrication out of use 15 years

Hi Snowbird. Your mixer was manufactured in late 1940's or early 50's. It was sold with one all-purpose combination whisk/beater. There is no dough hook available from Kitchenaid. There are two greases you can use in your mixer. Shell Darina-2, or Chevron FM ALC EP-2, the Chevron product is rated as "food grade", meaning that it is safe to ingest if it drips into the food you are mixing.

Remove screws and cover to expose the transmission. Remove all traces of old grease and replace it with one of the above "approved" greases. If you find this solution helpful, please rate it. ricardok45

More info re: n50 hobart mixer

Judy. Hobart was sold to Illinois Tool Works (ITW) several years ago. The Kitchenaid product line was sold to Whirlpool Corp. several years ago too.

The new N-50 mixers have a motor that is designed by Hobart, but no longer built by Hobart. Last year Hobart began out-sourcing approx. 12-15% of their componnents to Asia. Their parts catalog does not show anything but metal gears. I suspect the new motors have been built in Asia. Wattage is not the output of the motor, but how much power it takes to run the motor and is no indication of how much power goes into your mixing bowl. The true measure of mixing power is horsepower. The N-50 motors are rated at 1/6 HP. Wattage claims by mixer manufacturers is a complete snowjob, and they all do it. Consumers have no protection as a result of this policy. It is a marketing ploy to make you believe that this indicates output power. Shame on all of them! Most componnents of the new N-50's are still manufactured in the USA.

I see that you've done some homework on Kitchenaid Mixers. I wish I had before I bought mine. Yes, they have a plastic transmission housing, and yes, they fail under strong loads demanded by bread dough and stiff cookie dough mixtures (my HD Professional 450 watts failed 5 months out of warranty, after only 30 uses making bread). Go to the website and search for Kitchenaid mixer problems and reviews and brace yourself for a shock.

My mixer failed on Oct. 28th. and I had to fight tooth and nail with Kitchenaid to get them to re-imburse me for the cost of the parts that were destroyed by the housing failure. Here we are in 2009 and I'm still waiting for one more part. Kitchenaid parts take at least a month to arrive (in my experience).

I didn't do the research on mixers until mine failed. Since then I've purchased an older Hobart N-50 (with a motor BUILT by Hobart), and this is what I recommend you do, as it will save you much grief down the road. Mine was manufactured in 1990 and only needed. re-greasing to make it like new.

You can find them often on eBay but will have to buy without trying them. Try to find one that is newer rather than older, as a rebuild will get very expensive. I got mine from a Rest. Equip. Wholesaler and was able to try it out in all gears. The previous post (solution) was correct in saying that you should look for one that has a black knob on the shifter handle, this will be a newer one as opposed to an ancient one with an all metal shift lever and potentially worn out innards. If you find one, take it to Hobart, or a Hobart tech can come to you (check service rate) have the unit cleaned, inspected and re-greased. Sit back and take comfort in the fact that these mixers were built like a tank, and will probably outlast you.

Most of all. Good luck, and happy hunting. ricardok45

Loud and throws flour all over

Do you find the motor running too fast at the lowest setting? Then you need to bring it to someone to adjust the low speed setting. If you are preparing double batches you are over loading the mixer and/or using too fast a speed setting to mix. Don't try to double recipes just because the bowl can handle the volume, the motor cannot and will not last very long if stressed mixing dough frequently.

Clicking noises. Mixer doesn't have enough power to mix.

You have a drive gear that runs off the motor gear. That gear has a problem. It has either broke away from the weld or you have a pin or key sheared.

It sounds like you need to change the brushes. You can look up your parts manual online here and then buy them online. Should be under $10.
