Question about Hobart A200 Stand Mixer

Hobart A200 noises

I'd really appreciate some input regarding an older A200 (#794389) that I have.  It is making a periodic noise that seems to coincide with the occasional clutch slip?  I assume it is the clutch slipping as the planetary motion speeds up momentarily before settling back down to normal speed.  All 3 speeds of the transmission function and the attachments are not hitting the bowl.  The machine has sat idle for quite some time so I was wondering if there is anything I can do (grease?) to refurbish it a little.  Here's a quick video of it kneading a small piece of dough.  I wasn't able to catch the 'slip' or change in speeds but these are the noises that I'm hearing.  With the exception of the noise and occasional speed hickup, it is kneading fine.
Many thanks!

Hi, here is my opinion: 1) your planetary, or attachment hub is making the noise as it goes around, and there is grease in the gear ring that keeps it lubricated, it may be as simple as removing the planetary grease ring ( the chrome ring), and taking loose the bolt and lowering off the hub and cleaning the old grease, and installing new, reassemble in reverse. You may also have bad bearings in the shaft portion of the planetary ( the shaft your attachments go onto) allowing the shaft to "wobble" a little bit causing a slight misalignment as the smaller gear goes around while mixing. How far you want to go is up to you.
For your other problem, I have seen the brass clutch bearings stick on the main shaft in the transmission, causing the planetary to momentarily speed up, or to maintain a wrong speed ( 2nd or 3rd) when set to first, but that would require full disassembly of the transmission. Best left to someone who has done it before, but if your inclined, go for it, but get a part breakdown first, or take pics as you go. Hope at least some of that helps, and thank you.

Hobart n -50 where do i put grease in, machine makes a grinding noise

If your N-50 is making a grinding noise there is a strong (almost certain) possibility that the cause is more than just needing more grease.

The sources of the noise are from the transmission case (front portion of the motor housing) and/or the planetary (where the blade attaches).

A search online should turn up the N-50 Service Manual.

With luck, it may be that the two adjustments specified in the Service Manual will do the trick

Three things come to mind regarding the noise:

1) If simply greasing the planetary does not do the trick, then

2) There are two adjustments to the transmission detailed in the Service Manual. And if that is not the cure

3) The transmission housing will need to be removed to find the source of the grinding. This is where the grease is truly encountered.

Rattling noise after changing the planetary gear

The housing has to be worn if the bearing has play. Try a little tape around the bearing, or some thin brass shim stock. Of course epoxy may be a solution, if applied around the i.d. of the bearing seat. A little shortning on the bearing will keep it from sticking to the epoxy.

Kitchenaid Artesian makes a slight thumping noise when grinding meat

Something is out of balance, the front or rear bearing sounds like the culprit. the rear bearing is a relatively easy fix from the rear of the machine the front bearing is a little harder and will require a full tear down,

There is a sometimes problem that can fix a bearing problem that is actually not a bearing problem but a loose nut problem. At the rear of the mixer after you have removed the rear end cover get down to eye level with the rear of the mixer look to the right and left of the copper and black plastic speed switch plate and you will see a 3/8 nut on each side of the rearing housing, these sometimes get over tightened or come loose, you need a nut driver to operate them. tighten them up and turn on the mixer if there is a noticeable change in the pitch or sound of the mixer or the knocking gets worse turn them back the other way and listen again, if the knocking goes away then it was the nuts, it is only a sometimes fix, but it can be the problem,
if it is not the bearings i would generally start my fix by going to the gears first, The worm gear can be going and that will also take a tear down to fix but easy to do, you will need a new gasket, grease, a new worm gear and plenty of paper towels, it's messy. how long has it been thumping? how old is the machine? the worm gear fix has several really good you tube vids for this, just type in broken kitchenaid and you will get several, please let us know if this helps

Mixer making a grinding noise when turned on

It sounds like it is the worm follower gear, it is the most common gear to wear out as it takes the most pressure but it could also be one of the three bearings that are in there also, or it could be the worm gear, you will just have to open it up to look for wear. there are several really good videos on you tube that will show you how. it really is an easy fix if you are a good handy person, hope that helps

Hobart A200 Noise

After viewing and listening to your video, my first guess would be bad bearing(s). The sound varies with the speed of the agitator, so the noise is at the speed of the transmission shaft or planetary area. These mixers use very common standard bearings. As such, they are available very reasonably from sources OTHER than Hobart. You will need to take the transmission apart in order to find and solve the problem. Study the parts manual in detail. It seems complicated, but once you understand it, it is logical. I highly recommend that you get a really good understanding of how it works and goes together before you start taking it apart though.

Sparking at brushes

This isn't abnormal although cleaning the armature with fine emery or sandpaper can help.BTW, new brushes will always need a period of run-in before their contact with the armature has reached its best.

The problem is in your lift handle cams, you need to take the pedistal apart and clean and grease all the cams. I take them apart and wire brush them and use white lithium grease to keep them from freezing up.
