hold the rope in the proper groove. Side pulling
and excessive load swing will severely damage
the rope guide and must be avoided.
WARNING
Side pulling and excessive load swing
will severely damage the rope and rope
guide. Failure of these components may
result in injury.

parts list in Section IX.
(1) Remove socket head cap screws and lock
washers (Items 8 and 9). Take off mounting
clip (Item 7).

Once shoulder bolts are removed, the
halves will separate and, if not properly
supported, the halves could fall.
(3) Carefully unhook the rope tensioning spring
(Item 3), which is under tension.
WARNING
The rope tensioning spring is under
considerable tension; use caution when
unhooking to avoid injury.

from the drum. When reassembling the
rope guide be sure the plastic shroud (Item
2) fits snugly in the rope guide body
groove.
(5) Thoroughly clean and inspect all
components.
(6) Follow steps in reverse to reassemble. Be
sure to re-grease the rope guide with MPG
