Default Re: Staton crankshift kit with Honda GXH50 motor comparison to Subura motor setup.

The sealed bearing carriers for the crank axle are still a problem, it appears Staton is still only cutting the threads to half the required depth and therefore the bearing carriers will not thread into the bottom bracket housing. Previous build and builds by others have had this same problem, Staton needs to re-program his CNC machine for deeper cuts on these threads.

So I had to lathe re-cut these threads an additional .016" on the diameter to make them fit to the bottom bracket, which is no easy chore when having to pick up existing threads especially ones with a left hand twist.

Photos show bearing carrier threads that are too shallow before being re-cut, re-cut on the lathe, and carrier threads after the re-cut that now fit the bottom bracket correctly;
