6. Remove locknuts (46), lockwashers (47), washers (48)
and rubber mountings (49) securing brace rods (51) to
assembly.
7. Remove locknuts (50) and lockwashers (47) securing
brace rods to the radiator assembly. Remove brace rods
(51).
8. Ensure fuel lines connected to fuel cooler mounted
at front of radiator assembly are identified for ease of
installation and with suitable containers available to
catch leakage, disconnect fuel lines. Fit blanking caps
to open lines and ports.
9. Ensure hydraulic lines connected to hydraulic oil
cooler mounted at front of radiator assembly are
identified for ease of installation and with suitable
containers available to catch leakage, disconnect
hydraulic lines. Fit blanking caps to open lines and
ports.
10. Ensure hydraulic lines connected to fan drive motor
(12, Fig. 2) mounted at rear of radiator assembly are
identified for ease of installation and with suitable
containers available to catch leakage, disconnect
hydraulic lines. Fit blanking caps to open lines and
ports.
11. Disconnect deaeration line (30) from elbow (29) in
radiator assembly and deaeration line (28) from elbow
(27) in coolant inlet pipe (25). Identify lines for ease of
installation and cap open lines and elbows.
12. Disconnect all clips and clamps securing fuel
cooler lines, hydraulic lines and deaeration lines
attached to radiator assembly and coolant inlet pipe
(25). Move all lines away from radiator assembly to
prevent fouling on removal of radiator assembly.
13. Slacken clamps (23) and remove coolant inlet pipe
(25), hoses (24) and clamps (23) from radiator
assembly and engine thermostat housing.
14. Slacken clamps (23) and remove coolant outlet
pipe (26), hoses (24) and clamps (23) from bottom of
radiator assembly and engine water pump inlet.
15. Slacken clamps (5, Fig. 3) securing cooler hoses
(6, Fig. 3) to air inlet pipe (4, Fig. 3) and remove air
inlet pipe from charge cooler assembly (2, Fig. 3) and
engine turbocharger.
16. Slacken clamps (5, Fig. 3) securing hose (6, Fig. 3)
and elbow (7, Fig. 3) to air outlet pipe (3, Fig. 3) and
remove air outlet pipe from charge cooler assembly (2,
Fig. 3) and engine inlet manifold.
17. Install two eye bolts in lifting bosses on top of
radiator assembly. Using suitable lifting equipment
support radiator assembly.
18. Remove bolts (7), snubbing washers (8) and
locknuts (9) securing radiator assembly to mounting
brackets at the front of the frame.
19. Remove radiator assembly from the vehicle to a
clean area for disassembly. Support radiator standing
upright to allow access to front and rear of radiator.
