3. Place a suitable container under the center of the ra-
diator to allow coolant draining. Remove pipe plug (item
12 in Fig. 8) (hex socket head) from bottom of the radia-
tor and completely drain the radiator.
4. Disconnect upper and lower radiator hoses from the
radiator. Also, disconnect overflow bottle hose from the
vent tube near the radiator cap.
5. Thoroughly clean hydraulic hose ends and oil cooler
fittings to prevent hydraulic system contamination. La-
bel hydraulic lines for assembly purposes.
6. Remove hydraulic lines from oil cooler fittings. Install
clean plugs in hose and tube openings to prevent con-
tamination. Remove and discard O--rings from oil cooler
fittings.
7. Remove four (4) screws that secure fan shroud to
frame. Carefully position fan shroud away from radiator
taking care to not damage fan.
8. Remove two (2) flange head screws (item 10) and
flange nuts (item 11) that secure the radiator support to
the frame. Lift support from radiator.
9. Carefully lift radiator and oil cooler assembly from
the machine.
10.Plug radiator, oil cooler and all hose openings to pre-
vent contamination.
11. Inspect bulb seals on radiator and oil cooler assem-
bly and replace them if damaged or hardened. Also,
make sure that three (3) isolator mounts (item 5) are in
good condition.
12.Separate radiator and oil cooler if necessary (Fig. 8).
Installation (Fig. 7)
1. If radiator and oil cooler were disassembled, position
oil cooler to radiator and secure with removed fasteners
(Fig. 8).
2. Check that gap between radiator and oil cooler is
less than 0.090" (2.3 mm). If gap is more than 0.090" (2.3
mm), fill gap with silicone sealer to ensure effective seal-
ing.
3. Remove all plugs placed in radiator, oil cooler and
hose openings during the removal procedure.
4. Carefully position radiator and oil cooler assembly to
the machine. Make sure that lower pins engage isolator
mounts (item 5).

5. Position the radiator support to the top of the radiator
and oil cooler assembly. Make sure that radiator pin en-
gages isolator mount in support. Secure support with
two (2) flange head screws (item 10) and flange nuts
(item 11).
6. Carefully position fan shroud to radiator taking care
to not damage fan. Secure fan shroud to the frame with
four (4) screws.
7. Make sure that equal clearance exists at all points
between fan shroud and fan. Clearance should be from
0.250" to 0.330" (6.4 to 8.3 mm).
8. Connect radiator hoses to the radiator and overflow
bottle hose to the vent tube near the radiator cap. Se-
cure hoses with hose clamps. Make sure that hose
clamp on lower radiator hose does not contact alternator
belt.
9. Install new O--rings to oil cooler fittings. Connect hy-
draulic lines to oil cooler (see Hydraulic Hose and Tube
Installation in the General Information section of Chap-
ter 4 -- Hydraulic System).
10.Apply thread sealant to threads of radiator plug (item
12 in Fig. 8). Install plug into radiator opening.
11. Check that no gaps exist between radiator, radiator
frame and machine frame. If necessary, seal gaps with
silicone caulk.
12.Fill radiator with coolant. Make sure that overflow
bottle coolant level is correct.
13.Check hydraulic oil level and adjust if necessary.
14.Close and latch hood.
