Working on a Lightning and I have 2 motors. Ordered part number 68-3300, clutch nut from an eBay
seller that sells lots of British bike parts.
It doesn't fit either of my transmission main shafts. Seems to small.
Ordered another, same part from a Britbike forum sponsor, it is identical and doesn't fit.
Every reference says this should be 9/16" 20 tpi
(except the Greg Marsh fastener database which says 68-3300 is 13/16" 20 tpi)
Should I look for a 13/16" 20 tpi nut? Can't be that
I'm tempted to buy a 5/8" 20 tpi from British Tool and Fastener to see if it fits.
Anyone know what might be going on.
