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.

Man vs. machine, I’m betting on you Paul!

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, 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.

That’s good, bearings are easy to replace as long as you can get them

[processhead]

Pivodog Yes, they were available and inexpensive.

processhead great find.

processhead Let us know the progress!

[processhead]

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

[processhead]

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??

[processhead]

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.

[johnsbrewhouse]

processhead Yes, it’s the front bearing in the Alternator in most GM products. It’s a 203FF generally. Back in time we used to replace bearings and brushes in alternator and rebuild them before they sold rebuilt units.

processhead I notice there are bearing supply stores in Omaha.
The one we have here you can take a bearing in and they will identify and match it usually in stock
Motor info would also help

[lkrfletcher]

processhead awesome

There 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.

[calldoctoday]

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?

[processhead]

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.
