On my Hetzer it is the KCM's that are fixed and I let the shaft float in 
the KCM's and just put a split pin at each end to stop the sprockets from 
falling off.
I have noticed that when being driven the split pins are quite often 
rotating [ in the same direction luckily !!! ] so maybe it should not be fixed.
