ANCHOR WINDLASS FREE WHEELING OPERATION
1.
Perform the Anchor Windlass Pre-Operation procedure in this work package.
! CAUTION
When operating the anchor windlass in the free wheeling mode, the windlass must be carefully
observed and controlled to ensure that the windlass speed does not cause the chain to "jump the
cat" causing damage to the anchor windlass.
NOTE
With the dog clutch disengaged and the brake released, the wildcat will free wheel, allowing the
anchor to free-fall. Manipulating the brake slows or stops the anchor as desired.
2.
Set both anchor windlass brakes (figure 1, item 4) by turning the anchor windlass brake handwheels (figure 1, item 5)
fully clockwise.
3.
Disengage the dog clutch (figure 1, item 6) by performing the following steps:
a.
Remove the dog clutch tool from the frame-mounted bracket.
b.
Loosen both wing nuts (figure 1, item 7) on the face of shifter ring (figure 1, item 8).
! CAUTION
Maneuvering the main shaft may be necessary (with the brake set) to engage the dogs with the
clutch jaws on the wildcat. Attempting to engage dogs and clutch jaws when not properly aligned
could damage the windlass.
c.
Verify that the anchor windlass brake (figure 1, item 4) is set by rotating the anchor windlass brake handwheel
(figure 1, item 5) fully clockwise.
d.
Verify that the pelican hooks (figure 1, item 1) are secured to the anchor chain (figure 1, item 2) and that the pelican
hook turnbuckles (figure 1, item 3) are tight.
e.
Set the two-speed control lever (figure 2, item 1) to LOW SPEED.
f.
Operate the RAISE-LOWER control (figure 2, item 2) until the slots in the dog clutch (figure 1, item 6) are aligned
with the slots in the shifter ring (figure 1, item 8).
g.
Insert the dog clutch tool in the nearest slot that is aligned with the dog clutch (figure 1, item 6) and the shifter ring
(figure 1, item 8).
NOTE
A 50-degree movement of the clutch shifter ring is required to fully engage or disengage the dog
clutch.
h.
Pull the dog clutch tool aft to disengage the dog clutch (figure 1, item 6).
i.
Tighten both wing nuts (figure 1, item 7) on the face of the shifter ring (figure 1, item 8).
4.
Remove the pelican hook (figure 1, item 1) from the anchor chain (figure 1, item 2) by loosening the pelican hook
turnbuckles (figure 1, item 3).
