Fit the standard and the VBC 235 versions

Assembly instruction:

File a flat spot as show on the axle.  The grub screw should set here.  According the version of DGD011 you've, there is the chance to use a dual grub screw.  If so, it's highly suggested to use both grub screw for a better fixing.  Do not over tight the M4 thread. Especially on Gear Diff, there is no need to over torque it.  Over torque might lead to thread loosing.
