5-9c single reeved above, proceed with rereeving following
steps below:
(1) Pass other end of rope thru bottom opening of hoist,
between floating limit rod and motor, and attach rope to cast
dead end anchor fitting. A slot is located at top of fitting to
accept cable. Reinstall bolt and lockwasher in end of anchor
fitting to lock rope compression fitting in place.

place bottom block sheave in loop. Lower sheave into bottom
block and insert sheave pin. Replace key plates and bolts

twisted. Should the two parts of rope tend to wind around
each other, remove cable from anchor slot and untwist cable.
Reattach the cable anchor.
(4) Lubricate cable per paragraph 4-3.
(5) Remove key plates or snap rings from upper block
sheave(s) and slide out upper block sheave pins, releasing
upper block sheaves. Remove wire rope from sheaves.
