■
Norseman and Sta-Lok Fittings
Subtract 17" (432 mm) from your overall pin-to-pin length and
cut
the wire at that point.
When the headstay is shortened 17" (432 mm) the turnbuckle will be one half to two
thirds open, allowing adjustment of the headstay length.
If necessary you may shorten your headstay up to 19" (483 mm), but shortening a
wire more than 17" (432 mm) will limit headstay adjustment.
If the length of the turnbuckle being removed is over 19" (483 mm) a toggle must be
used to compensate. Be sure to change the headstay length measurement to reflect
the use of this toggle.
Use only Norseman or Sta-Lok fittings provided by Harken to insure that the length
and threads are correct.
Length Check:
Check your length by opening the terminal, removing the "cone", and
placing the fitting on the wire. The distance from the center of the eye at the top of the
wire to the end of the stud should be equal to the headstay length less 12

Rod Fittings
Subtract 18" (457 mm) from your overall pin-to-pin length and
cut
the rod at that point.
If the cut point is on the upper part of your turnbuckle, but below the
actual rod, tap the turnbuckle up the rod to free the coldhead from
the turnbuckle and cut the rod at the correct point.
When the headstay is shortened 18" (457 mm) the turnbuckle will be
one half to two thirds open, allowing adjustment of the headstay length.
If necessary you may shorten your headstay up to 20" (508 mm), but
shortening a rod more than 18" (457 mm) will limit headstay adjustment.
If the length of the turnbuckle being removed is over 20" (508 mm) a toggle must be used
to compensate. Change the headstay length measurement to relfect the use of this toggle.
Use only rod fittings provided by Harken to insure the length and threads are correct.
Length Check: Check your length by placing the rod fitting alongside the rod with the
nosepiece in its proper position. The distance from the center of the eye at the top
of the headstay to the end of the stud should be equal to the headstay length less
