Just disassemble and take to a facility like KAMAN where they can match up the bearings.
With those caps it is a Deere and old. We had one always liked those grease caps.Partscstalog.deere.com
This will give you parts drawings and parts numbers. You might be able to figure out what you have from there.
Are you sure it’s JD running gear?
Most bearings will have a part number stamped into them. That’s not a Deere part number, it’s a bearing part number that should cross reference to other bearing manufacturers.
Working on my phone and didn’t open the pics up larger. Looks to be JD!👍With those caps it is a Deere and old. We had one always liked those grease caps.
I have a whole stack of them and I believe all pre 1980. Most of equipment I don't remember. Came from a box I cleaned out of the desk in the milkhouse. Equipment brochures from 70's, 80's, 90's. Seed catalogs from same time period. Cigar box full of equipment quotes and other information that looking back is now very interesting. Dad purchased a first year JD6400 and came across the extended warranty certificate JD sent. Went from 2 years/2000hrs to 3 years/3000 hrs. I know ours had issues.Imagine...writing something on a piece of paper. How antiquated. 🤣 🤣
