5. Use the shaft wrench to loosen the upper
and lower adjustable shafts, as shown in
Figure 41. DO NOT loosen them too much
or the clamp nut will fall out and you will have
to remove the gear bracket to reconnect the
adjustable shaft to the clamp nut.
6. Loosen the cap screw on the gear bracket
with the 5mm allen wrench as shown in
Figure 42.
7. Pivot the gear bracket away from the drive
gear as shown in
Figure 43.
8. Slide the gears on the upper adjustable shaft
to the top of the gear bracket, and hand tight-
en the shaft to keep it from meshing with the
gears on the lower shaft.
9. Remove the 35T and 90T gears (those in the
forward position on each adjustable shaft).
10. Place the 50T gear on the upper adjustable
shaft and place the 66T gear on the lower
adjustable shaft.
Note—when placing the
gear on the lower adjustable shaft, slide it up
or down to make it mesh with the gear on the
pivot shaft.
11. Place the special lock washers on each
adjustable shaft to ensure the gears are
completely in place.
12. Thread the hex nuts back onto the shafts,
and hold the shaft in place with the shaft
wrench as you tighten the hex nut.
13. Loosen the upper shaft to allow the gears to
slide down the gear bracket and mesh with
the middle set of gears.
14. Pivot the gear bracket toward the drive gear
so all the intended gears are in mesh.
