ANSI and National  Standard Bushings
Head Liners
   
Type HL
All liner bushings have honed or ground I.D.'s.  Liners
with I.D.'s up to 1" are concentric within .0003" T.I.R  to
the O.D.  Larger I.D. sizes are held to .0005" T.I.R.   All
unground  bushings  are left as  machined on the O.D.
with concentricity of approximately .006" T.I.R.
