Case 310D lower track rollers

[campcrawler]

I'm looking for the bearings kit for the 310D ( 4 rollers). The two bearings I can read have part number: 5207W (FAFNIA); and 207K (FAFNIA MADE IN USA). I need the double row ball bearings, seal, spacer bearing, and shield.
The shaft has the grease cert on the end.

I will have to do some checking, when I bought my 310F several years ago the previous owner threw in a box of bearings & seals for the rollers they were NOS Case parts, I never used any of them as I got a deal on a complete used undercarraige for my machine. I did lookup the Case numbers and the parts are the same between the two series. If I can find the parts I'll check what I have and how many and we can go from there, I will part with them.

Are the bearings FAFNIR?

Are the bearings FAFNIR?

Yes, they are FAFNIR. I wrote FAFNIA in the original post because I was unclear of the lettering. Thank you.
5207W C1 (FAFNIR); and 207K (FAFNIR). I need the angular double row ball bearings, seal, spacer bearing, and shield.
The shaft has the grease cert on the end.
I found some online (Lily and Universal Parts) that appear to be the same size but am not sure of the quality. I'd like to replace all of these parts, including Oil seal, Spacers, and Shields.

If it helps, I am using part numbers from the Case Parts Catalog No. A679
On the Battery Box is a plate with Serial number 3914017, but on the engine block near the starter is the number 301401. My rollers look exactly like the one in the A679 manual with the grease zerk on the end of the shaft

Fafnir is part of Timken now. Google FAFNIR 5207W C1 and FAFNIR 207K, if result is correct bearing seems to be lots of seller choices.

According to the Case parts site A679 parts manual is correct for 310D. If the 9 in your serial nr is a zero instead appears to be a 1963. Case engine nrs are not overall machine chronological, just avail as the same engine may have a part(s) change down the line.

Thank you for this information. It's been difficult to locate the actual year and model (310D, or G, or other).

I stock a complete lower roller for 195. if that helps

I'll vouch for Don L. ([email protected]). I've bought parts from him in the past. He also has a large salvage yard in the MN tundra. You'll get what he states it is for a decent price. Not only that he drinks dark beer, can't beat that.

drinks dark beer, can't beat that.

Warm or cold?

I did find that box of parts, but there is not much there. 4 seals #D29138, 2 seals # D31322, and 1 of the #32056 the shaft with the zerk. and a couple bearings but they are used. The rest of the stuff was just random things thrown in. If you have any interest let me know.

You can buy new rollers for just about the same price as rebuilding them. Google R36470. I see some for $210. They are face sealed so you'll never have to grease them. Only trouble is, the diameter may not match up perfectly with the old rollers, so I bought a complete set. Otherwise they will fit.

Thank you for looking. I found the parts I needed at various sites. I am looking for a track master link with pins. Any laying around?
