So 86 from the frame number seems to be the build year which seems to be right when he moved into his shop at the time.
I tried loosening the bolts on the rear wheel for fitting and instead of the bolts turning the seals loosened and unscrewed the hub covers instead. There’s a space for a hex key on the inside of the hub cover screw but a 4mm is too small and a 5 too big.. turns out because it was US made they’re using imperial measurements so need to get myself some new hex keys. Got in touch with profile racing and this seems to have been an issue with their early track hubs. This is what I got back from them.
“So I believe you need a 3/16" allen key.
That design did prove to be difficult to remove the cones. Later on
this did change to a push on cones like how the BMX hubs work.”
Got a mate with a set of imperials so going to see him when he’s back from work tonight to get this sorted for now and get some ordered for myself. At least got to see in and confirm it was sealed bearings, still spinning really nicely.
