feetupfun Posted February 25, 2018 Report Share Posted February 25, 2018 Here is one type of M49 rear hub. I just measured the liner of this one as 144mm OD. Nominal ID is 140mm. I am planning plan to machine this one out to either no grooves or a maximum of 142mm ID with some grooves remaining. There is another type of M49 rear hub fitted to early build M49s that I will post up a photo of later if you think it is helpful. This earlier hub has a liner with the same nominal ID (140mm) but has a much bigger OD (147mm) 1 Quote Link to comment Share on other sites More sharing options...
