112. Hose Reel Air Hoses (fig. 10)
a. Removal. Release the hose reel lock pins so that the reels can revolve freely. Disconnect the free ends of the
hoses from the couplings at the rear of the side tool boxes and unwind the hoses from the hose reels. Then loosen the
two hose clamps and disconnect the hoses from the hose reel service valve couplings and slip the hoses from the slots in
the hose reels.
b. Cleaning and Inspection. Do not clean hoses with cleaning solvent or other petroleum products. Wash with
warm, soapy water; then rinse with clear water and blow dry with compressed air. Examine the hoses carefully for cracks
or breaks and for signs of deterioration. If hoses or their couplings are damaged, they must be replaced.
c. Installation. Slip the end of each hose through the slot in the hose reel and connect it to the service valve hose
couplings. Hoses must unwind over the tops of the hose reels and toward the rear of the truck. Wind the hoses onto the
hose reels and connect the end of each hose to the stationary coupling mounted at the rear of the side tool boxes. Lock
the hose reels with the lock pins.
113. Hose Reel and Service Valve
a. Removal (fig. 50).
(1) Remove the hose from the hose reel (par. 112a).
(2) Unscrew the service valve (1) from the end of the slip fittings (7) and disassemble the hose coupling (18)
from the valve.
(3) Remove the lock ring (4) from the groove around the reel shaft hub, and slide off the reel.
b. Disassembly (fig. 50).
(1) Remove the two self-tapping screws (11) and lockwashers (10) and lift the lock pin assembly (9) from the
hose reel (8). If the lock pin assembly is to be disassembled, support it solidly while driving out the taper
pins (13 and 16). Then slip the collar (12), spring (14) and support (15) from the lock pin (17).
(2) Remove the four fillister head screws (2) and lockwashers (3) that fasten the retainer fitting (5) inside the
reel shaft hub, and remove the retainer fitting, slip fitting (7) and packing (6).
c. Cleaning and Inspection. Wipe the hose reels and lock pin parts with a cloth dampened with cleaning solvent.
