Hi folks,

I hope this is in the right place. It’s a repair issue, but for vintage parts.

I recently acquired an interesting pair of hubs. They’re sealed bearing Sunshine hubs. The rear is a hi-lo hub with a large flange on the freewheel side and a smaller one opposite. The front is a medium flange with a 50mm spoke hole circle. They spin stiffly, but are not gritty or notchy. I’m assuming that they are re-buildable, but am wondering if I could use a syringe needle to get some Phil’s Tenacious Oil into the bearings and onto the edge of the seal. Also does anyone have experience replacing these type of bearings? The bearings are labeled: NTN Japan 629 LB or L8. I haven’t researched their availability yet in hopes someone has some info on these hubs.

Any info would be greatly appreciated.

Thanks and regards,

Van
