(2) Install the pump (fig. 24) by inserting the six hex head bolts and lockwashers that fasten the body to the
crankcase. Apply sealing compound to all gaskets and replace gaskets if they appear badly worn or
damaged.
(3) Install the five short lengths of hose (1), elbow (20), radiator-to-pump connection (25), and radiator inlet pipe
(3), by tightening the screws in the appropriate clamps (2). Before making connections, coat mating
surfaces with sealing compound.
(4) Close the drain cock (15) and fill the radiator with coolant.
87. Replacing the Fan Guard
a. Removal. Unscrew the self-tapping screws (29) that fasten the fan guard (30) to the radiator shroud. Remove the
hex nuts (16) and lockwashers (17) that secure the fan guard rods (18) to the fan guard support (21) and lift off the
assembled guard and rods. If necessary, remove the upper hex nuts (16) and lockwashers (17) and disassemble the rods
from the fan guard.
b. To install the fan guard, reverse the procedures in a above.
88. Radiator and Fan
a. Removal.
(1) Open the radiator drain cock (15) and drain the coolant into a clean receptacle for possible re-use.
(2) Remove the radiator shutter assembly (par. 84a).
(3) Remove enough of the compressor housing (par. 128) so that the radiator is exposed for removal.
(4) Disconnect the coolant hoses from the radiator inlet and outlet connections (par. 86).
(5) Remove the fan guard (par. 87a).
(6) Remove the cotter pins (8), castellated nuts (9), plain washers (10), and hex head bolts (12) that fasten the
lower radiator mounting angles to the compressor frame.
(7) Lift the radiator (7) from the frame, being careful not to lose the four rebound units (11) that serve as
vibration dampeners between radiator and frame.
(8) Remove the fan belt (par. 85a). Remove four hex nuts (23) and lockwashers (24) to dismount the fan (22).
b. Installation.
(1) Place the fan (22) on the crankshaft pulley and attach with four hex nuts (23) and lockwashers (24). Install
the fan belt (par. 85b and c).
