Figure 2-9. Winch and controls.
c. Brake Lever. The brake lever (2, fig. 2-9) is connected to the winch through a flexible push pull cable. Pushing the lever toward
the winch sets the brakes and holds the cable drum. A ratchet and pawl on the lever hold it in the applied position until released by
the operator. To release the brake, lever is pulled toward the operator.
d. Shift Lever.
CAUTION
Each time the shift lever is moved from one position to another, the speed lever (1, fig. 2-9) must be
released to stop the winch motor. Failure to stop the winch motor, prior to shifting the winch from one
position to another, may result in damage to the winch gears.
This shift lever (3, fig. 2-9) controls the rotation of the cable drum. The lever has three positions:
(1) When the lever is in vertical position, the winch is in neutral.
(2) Pushing the lever towards the winch, reels in the cable.
(3) The lever is pulled toward the operator for paying out the cable.
e. Free Spooling Control. The winch is provided with a free spooling feature that allows the cable drum to free spool. Pulling out on
the free spooling control (4, fig. 2-9) disengages a gear type clutch and allows the cable drum to free spool. The winch brake lever
must be released and the shift lever must be in neutral to accomplish free spooling. Pushing in on the control engages the clutch for
winching in loads or paying out line with power.
2-26. Hull Drain Plugs and Valves
WARNING
All drain valves must be closed before entering water. There are two 3/ 4-inch drain plugs and 11 drain
valves (fig. 2- 10) located at different points in the bilge area. The valves provide a means of draining
water from the bilge areas while the LARC is on land. The valves are operated by handwheels
connected to the valves by flexible shafts. The handwheels are located underneath the main deck in
the vicinity of the scuttle and hatch covers. All are easily reached with the exception of the one used to
drain the aft center bilge between the propeller tunnels. To operate this valve, one must crawl into the
starboard aft scuttle and cross amidship.
