Once shoulder bolts are removed, the halves will separate and, if not properly supported, the halves could fall.

WARNING

The rope tensioning spring is under considerable tension; use caution when unhooking to avoid injury.

(4)Remove the split plastic shroud (Item 2) 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 (Paragraph 4-7) after assembling.
