I will mic the race/hub fit prior to install. My thought was the torqued in place steel brake drum and spoke flange were not allowing open heat growth of the alloy hub and might allow distorted growth.
The 09195 race on the non speedo side came out rather easily, no heat, simple tap out.
The 09195 race on speedo gear side was tough removal, all the way, heat , hammering.
I was expecting the alloy spacers to be tough removal, but not the case.
I will check the fit and use 641 as needed.
641 is not stocked in my area, having to mail order, going move to other project issues.
