New Moto Guzzi Door Mats Available Now
Good luck with 123 so far.They stock the 28 ball double row angular contact bearings used on the 5 speed input/output shafts in the SKF Explorer series.
Could you link to those, please? I searched every way I could think of and didn't find them on 123. Edit: I found these: https://www.123bearing.com/bearing-3205-SKF.php but they're not C3.

Have you installed those? I installed an NTN 3025A in a transmission - when the case was warm (for installation) it spun fine, when everything was at ambient temperature, the bearing was very tight. Guzzi calls for C3 clearance bearings and that experience seems to bear out that they're necessary.
Shouldn't tighten up in a cold vs warm case (unless shafts are end shimmed incorrectly) . Double row bearing is anchored to shaft and case at one end. Other end of shaft is floating free so it can move laterally as temperatures change. Double row bearings were a gauge fit in the housing at room temperature.
Well, it did. No shaft in it, just the bearing in the rear cover. Cover warm - bearing spun freely, cover at room temp. - bearing tight. Pulled it out and put a C3 clearance bearing in - spun freely hot or cold. <shrug>

When I was selling bearings (along with other things) the Explorer range was supposed to be their top of the range line.
