processhead We’ll keep our fingers crossed. Those bearings & shaft can probably make quite a racket when they go or are not maintained.
There are bearings on the main knife shaft. They look like a pain to replace. I am hoping I don’t have to tear into the gear box to replace those.
processhead let’s hope that just the outer bearings do the trick. Otherwise, not too bad, but still a pain. The good thing is you can still work on something like this, so there is always hope, unlike a whole lot of other things these days. Still keeping my fingers crossed for you.

Well, a minor setback. The chopper was a little noisier than it should be while it was running.
I pulled the drive belt off the motor so the motor was the only rotating part of the chopper. The motor was kind of loud so I pulled the bearings out and they were pretty well roached.
The grease was dried up and the bearings were really rough when rotated by hand.
So new ones are on the way. I will put them in the motor and run it again and see if that is the only noise source.

Well, that sucks! Do the windings and brushes all look good?

It is a split phase induction motor, so no brushes and no rotor winding, just stator windings.
The rest of the motor looks good, and the start capacitor checks out good.
So I am not anticipating any other motor issues.

Pivodog Yes, they were available and inexpensive.

processhead great find! Please let me know if you ever find a grinder attachement for mine? I’ll pay?
Funny you should mention that.

PM headed your way. -

processhead Let us know the progress!

Bearings are supposed to arrive today, and I will be putting the motor back together as soon as the mail box door closes.

Wrong bearings arrived today. Operator error on my part. Stupid little part number and fuzzy eyesight.
Got an order in for the right ones.

processhead B203 0r 8203? Looks like B203 to me and my old eyes. That’s a pretty common bearing if it’s a B203.

I’m with you. B203 or 8203.
So which was it Paul?? -
The original bearing measures OD 40 mm x ID 17mm x Width 12 mm
The owners manual for the chopper has a parts list and a diagram. It shows that the motor bearing have an OEM part number of ND Z99503 and a Hobart part number of BB-5-30. When I looked up the dimensions for OEM bearing, they match the original bearings that are in the motor, OD 40 mm x ID 17mm x Width 12 mm.I was able to find and ordered the Z99503 bearing which were used in a lot of General Motors /Delco applications.
My research shows that B203 is a one-way clutch bearing.
8203 is a type of thrust bearing.
So neither of these appear to be viable crosses unless I am missing something.Paul

The one we have here you can take a bearing in and they will identify and match it usually in stock

I found this Hobart 18 inch buffalo chopper today at an estate sale in a nearby town.
It came with all the important accessories including a #12 grinder and a “pelican” vegetable shredder, which I will probably try to find a new home for.
Chopper blades were in good shape and the grinder came with a 3/16 inch plate and a brand new Zico grinder knife.The drive unit looks like it had been sitting unused for a long time. When I plugged it in at the guys garage it just hummed. After getting it home and looking it over, I plugged it in to a dedicated 20 amp outlet in my shop. It started right up and ran as it should. The amp draw while it was running was under the name plate rating, so that’s a good sign.
Looks like all it will need is a good cleaning and I look forward to trying out the bowl chopper.I also bought a small Enterprise cast iron stuffer which you can see in the background of the top photo. A project for another day.

Motor info would also helpThere are supply houses here, and I called a couple of them earlier. In hindsight, bringing them in would have probably narrowed down the search fairly quickly with the resources they have at hand.
I feel pretty confident I have the correct ones located now and they should be here by the end of the week.

processhead I understand & wonder myself how I am able to continue looking at buildings. The number stamped on the bearing looks like 8203 to me, but possible B203 or 820B. Is there anywhere locally that you can take them too vs the online thing?

Making some progress today. I have the new bearing in the motor and the motor runs nice and quiet now like it should.
Next up I need to address a bad seal in the gearbox that runs the bowl. The oil level was low when I got the machine and there was evidence underneath that oil was getting past the seal on the input drive shaft to the gear box.
Seal should be here Monday. While I have it torn apart, it will get a couple of bearings. I need to turn a bushing that goes on the sheave clutch. Still under $60 total in parts so I consider that a win.
I am impressed by the build quality of these Hobart machines. All the subassemblies are constructed with heavy duty milled and machined parts.
They were designed to log thousands of hours, then be rebuilt and do it all over again.

Farking cool! I wish you lived in my neighborhood, I’d be over all the time watching you fix stuff. You know your mech!

Looks like your making some good progress.
