(2) Connect the air line (18) to the tube connector (3) in the air cylinder, and open the shutoff cock (29).
84. Shutter Assembly
a. Removal.
(1) Remove the air cylinder (21) from the shutter as instructed in paragraph 83a.
(2) Remove the six hex head bolts (24) and hex nuts (25) that fasten the shutter assembly (19) and bond straps
to the front hood end support. Remove the packing (26).
b. Installation.
(1) Fasten the new shutter assembly (19) and two bond straps to the front hood end support with the six hex
head bolts (24) and hex nuts (25). Be sure the packing (26) is seated between the mounting flange on the
shutter assembly and the radiator.
(2) Install the air cylinder as instructed in paragraph 83e.
(3) Check to see that the shutters and shutters-to-cylinder linkage move freely and easily.
85. Replacing the Fan Belt
a. Loosen the hex nuts on the through-bolt that attaches the generator to its mounting bracket, and tilt the generator
toward the engine until the fan belt can be removed from the generator pulley. Lift the belt over the fan.
b. Install the new belt around the crankshaft pulley and generator pulley.
c. Pivot the generator away from the engine on the through bolt. The tension of the fan belt must be such that
pressure of the thumb at a point midway between the two pulleys will deflect the belt approximately 3/4 to 1 inch. When
the generator has been pivoted enough to meet this requirement, tighten the through bolt hex nuts securely.
86. Water Pump Removal and Installation
a. Removal.
(1) Open the drain cock (15, fig. 28) and drain the coolant into a clean receptacle for possible re-use.
(2) The radiator inlet pipe (3), radiator-to-pump connection (25), elbow (20), or any one of the five short lengths
of hose (1) can be removed by loosening the screws in the appropriate hose clamps. (2).
