8. Loosen the jam nuts that hold the bottom end of the
cable to the cable bracket on the chain case. This
can be done using a pair of 1/2" wrenches.
See Figure 2.15.
9. Thread the bottom nut all the way off of the cable
housing.
10. Unhook the spring from the idler pulley arm, and
draw the cable through the slot in the cable bracket to
remove it.
11. Assembly notes:
11a. Install the cable by reversing the removal pro-
cess.
11b. The lock washer fits between the bottom nut on
the clutch control cable and the cable bracket.
11c. Visually check the operation of the cable and
idler pulley before installing the belt cover:
• The arm should relax far enough to allow about 1/
2" slack in the cable when the clutch control bale is
released.
• The idler pulley should draw up enough to tension
the belt when the clutch control bale is pulled up
against the handlebar.
• The spring at the bottom end of the cable should
be slightly extended, with visible gaps between the
coils.
• It should not require uncomfortable force to hold
the clutch control bale in the engaged position.
• Route the clutch control cable through the center
notch in the shift cover so that it does not chafe
against the input pulley
12. After final assembly, run the tiller and test its opera-
tion in a safe area. Run-test and adjust the clutch
control cable as described in the Clutch Cable
Adjustment section of this chapter.
