[ ] 9. Using caution not to cross the parallel cable pair, attach the longer end of the outboard
cable to either inboard termination slot of the right pinion as shown in Figure 20. Wind
that cable end onto the pinion 1/2 turn.
[ ] 10. Next, attach the other end of the outboard cable onto the remaining inboard termination
slot of the right pinion. It is important that the cables NEVER cross during their track
through the circuit. Check that the outer-most single cable of the pair, as it rides on the
pulley, remains the outer-most cable even on the pinion and that the innermost single
cable on the pulley remains the innermost cable. This will insure proper cable path
transitioning from the pulley to the pinion.

[ ] 11. Slowly wind the pair of cables onto the pinion with a tight pitch, placing a finger over
the cable against the pinion so that slack does not develop as you wind it on. Note that
during the first wrap of the cable pair, the cables must be jogged over to skip six of the
scalloped grooves (refer to Figure 20). After the cable pair spans the first six grooves
on the pinion, you should continue winding it onto the pinion with a normal tight pitch
that corresponds to the machined grooves.
When all of the cable is wound on the pinion, temporarily secure the cables to the
pinion with a piece of masking tape to maintain organization in the cable pair and tape
the pulley-pinion to the differential supports to prevent inadvertent rotation.
[ ] 12. Attach the longer end of the inboard cable pair to either outboard termination slot of the
left pinion (at the end nearest vertical support). You may require the aid of needle-nose
pliers or tweezers to help install the brass lugs in these difficult-to-reach terminations.
Wind the longer cable end onto the pinion ½ turn.
