remove these nuts to allow for the proper fit

connectors and try again.
4. Make sure the locking yoke and the rod con-

the pivoting rod connecter.
5. Position the locking yoke back inline with the
setscrew holes on the draw tube assembly,
then secure the setscrews and the jam nuts
as shown in Figure 10.

locking yoke into the holes on both sides of
the bearing housing. Make sure the
setscrews are completely and evenly
engaged into the holes, without being tight.

side, but still pivot freely. Tighten the jam
nuts.
