Cleaning
8) Clean all parts (Do not use aggressive solvents).

Warning: even one small debris can void freewheel engagement.
Warning: carefully check hubshell Splines (see below).
Hubshell Splines Check - IMPORTANT!
Clean and degrease perfectly hubshell internal splines, all of them.
Once hub-shell internal is perfectly clean check well with eye magnifier all the 24 splines, see
image.
Every spline corners (clockwise corners) should be well square and flat.
In case your hub has 24 used splines and you are not sure about it contact
us info@extralite.com providing clear close-up photo.
Potential risk
When riding HyperHubs with dirt inside the hard particles of sand can badly
grind the hubshell splines. Shortly the sand wears the hub-shell splines till the
"floating ring" will not move freely anymore. This easily causes an
uncomplete freewheel engagement and damages permanently the
newly installed freewheel parts. In this case replacing "floating ring" and/or
"Freewheel body" does not solve. The expensive hub-shell should be
replaced (or eventually sent back for re-sharpening).
