crown race seat & inner face of crown race should not be lubricated
fit should be tighter
two options for tighter fit:
a) Loctite type compound as mentioned previously
b) dimpling vertical face of seat with centrepunch as mentioned previously
each dimple creates a tiny parapet which increases the effective diameter of the seat
the nice thing about the Hatta headsets from Specialized is the presence of the O-ring seal to keep dirt out of the bearing; a feature especially helpful on a mountain machine
Tange Levin is an excellent value in a cup & cone headset but lacks this seal
