[ ] 6. Install the U-bend of the 2286mm cable into outboard termination loop slot such that
the longer end rides on the outboard edge of the 2
nd
-stage pulley. Gently push the cable
as far as possible into the slot. Place a piece of tape over the loop to prevent it from
dislodging during cabling. Repeat for the inboard loop such that the longer end rides on
the inboard edge of the 2
nd
-stage pulley.
[ ] 7. Starting with the 2032mm inboard cable (now doubled-over making a cable “pair”),
wrap the pair around the input pulley with a left-handed pitch passing twice underneath
it, as shown in Figure 18, such that the two cable ends hang over the left 2
nd
-stage
pinion. Tape the cable in place to prevent movement of the cable and loss of tension.

nd
-Stage Pulley
[ ] 8. Also with a left-handed pitch, wrap the outboard cable pair approximately ½ of a wrap
underneath the input pulley as shown in Figure 19 such that the two cable ends hang
over the right 2
nd
-stage pinion. This cable pair should pass between the two wraps of
the inboard cable pair. Tape the cable in place to prevent movement of the cable and
loss of tension.
