TIP: It is helpful to apply a piece of tape to prevent the lug from slipping out of the termination until the circuits are pre-tensioned.
Wind on this cable a 1/2 turn by rotating the pulley/pinion.

Without crossing the cables, attach the remaining brass lug of this cable to the
remaining 2
nd
-stage termination, located 180 degrees from the first termination. This
cable end should be inboard of the cable end terminated in the previous step. Again, it
might be useful to apply a piece of tape to prevent the lug from slipping out of the
termination.

Slowly wind the cable pair into the pinion grooves, by simultaneously rotating the
pulley/pinions and folding the elbow flat against the inner link. When all of the cable is
wound on, temporarily secure the right pulley/pinion with a piece of masking tape to
prevent your work from unwinding.

Locate the two brass lugs of the left cable. Make sure that the cables do not cross
anywhere along their path. Adjust the two ends coming from the elbow unevenly so
that the outboard cable end is approximately 35mm longer than the inboard cable.
Temporarily tape the cable pair to the pulley surface to keep it tight around the boss.

The next step is to install the left 2
nd
-stage cable into its respective pinion. Without
crossing the cables, take the brass lug of the longer cable and attach it to one of the two
2
nd
-stage pinion terminations located on the sidewall of the 1
st
-stage pulley.

Using your fingers to apply a generous amount of force, rotate the left 1
st
-stage pulley
relative to the right pulley
while holding the right pulley from rotating. The relative
rotation of the left and right pulley/pinions will wind the left cable into the pinion and
take up any slack in the 2
nd
-stage. Once all the cable slack has been taken up,
temporarily place a piece of tape across the 1
st
-stage pulley surface to prevent any
further counter-rotation of the halves.
[ ] 12.
Check the 2
nd
-stage cables to make sure that no cables have crossed.
