SINGLE CYLINDER HEAD/BARREL THROUGH STUD 6 5/8" (ST/ST)

WE STOCK THREE DIFFERENT LENGTHS OF THROUGH STUDS.  THE THREADS ARE IDENTICAL ON ALL THREE STUDS AND THE FIRST LENGTH QUOTED IS APPROXIMATELY THE LENGTH LEFT PROTRUDING FROM THE CRANKCASE ONCE THE STUD IS FITTED.  

19840        5 3/8", OVERALL LENGTH IS 6 5/16"
19841        5 3/4", OVERALL LENGTH IS 6 5/8"
18638        6 5/16", OVERALL LENGTH IS 7 3/16"

DUE TO THE CHANGES INTRODUCED OVER THE YEARS AND THE INTERCHANGEABILITY OF PARTS WE HAVE SOME CONFUSION OVER THE PART NUMBERS AND WHICH SLEEVE NUT FITS WHICH BIKE.

PLEASE NOTE: USE THE PART NUMBERS AS A REFERENCE ONLY AND RELY ON THE DIMENSIONS GIVEN.  ALL ARE THE SAME 3/8" X 26TPI THREAD.
