I tried adding a bit of light oil to get these vintage KKT pedals spinning a little better but it didn’t quite free one of the two up to satisfaction. I figured the cone was adjusted a smidge tight so I removed them both for service.

After disassembly it was clear. There was adequate lube in both but the last person in here had inadvertently assembled one with the bearing count imbalanced.
12 on one end and 10 on the other. It spun with just a little grinding feeling in my hand but undetectable when riding. Cones and cups looked undamaged so after a proper cleaning and new grease, they went back together.

I really hate rebuilding these loose bearing closed cage pedals. There’s so little space to get your fingers in there to set the balls and thread everything together with appropriate cone lash.
Good to go now.
