Radiator and Oil Cooler Installation
1. Install the seal bulb (item 1, Fig. 8A–4), seal bulb
moulding (2), and foam baffles (4) as required.
2. Position the oil cooler (5) within the radiator assembly
baffle (3).
3. Install the six 1/4-20 x 1-1/2" hex-head capscrews
(38, Fig. 8A–4), 1 /4" lockwashers (37), 1/4" flat wide
washers (36) and well nuts (35) securing the radiator
baffle assembly (3) to the oil cooler (5). Torque to 9
lb/ft (12 Nm).
4. At the bottom of the hydraulic system oil cooler
(Fig. 8A–6), install a new flat-faced O-ring seal in the
90° elbow and secure the elbow fitting to the cooler.
Use a back-up wrench and torque the elbow fitting to
155-165 lb/ft (210-224 Nm).
5. Secure the 3/4" I.D. x 28" hose (Fig. 8A–6) to the oil
cooler.
6. Carefully place the radiator into position at the oil
cooler. As required, place two foam baffles (item 4,
Fig. 8A–4) between the radiator and the oil cooler.
7. At the sides of the radiator, install the 3/8 x 1-1/2 x
5/16-18 hex-socket head shoulder bolts (item 12,
Fig. 8A–4), spacers (10), 3/8" rebound washers (7),
radiator mount bushings (9), radiator mount rings (6),
and 5/16-18 hex-lock elastic nuts (8) securing the
radiator at its side mounting tabs to the radiator
brackets (11 and 34).
8. Working from beneath the radiator, install two 3/8-16
hex-lock elastic nuts (14), 3/8" rebound washers (7)
and rubber mounts (17) secured to the welded studs
on the bottom of the radiator. Torque to 31 lb/ft
(42 Nm).
9. Working below the radiator, install two 5/16-18 x 3/4"
Grade 5 hex-head capscrews (31), 5/16"
lockwashers (30) and 5/16" narrow flat washers (29)
securing the radiator at the lower mounting tabs to
the radiator shroud (18). Torque to 18 lb/ft (24 Nm).
10. Working above the radiator, install two 5/16-18 x 3/4"
Grade 5 hex-head capscrews (31), 5/16"
lockwashers (30) and 5/16" narrow flat washers (29)
securing the radiator at the upper mounting tabs to
the radiator shroud (18). The radiator shroud
contains 5/16" weld nuts that retain the capscrews.
Torque to 18 lb/ft (24 Nm).
11. Uncap and connect the transmission inlet and outlet
hoses (Fig. 8A–5).
12. Install the fan (item 3, Fig. 8A–1) on the water pump
pulley on the front of the engine. Secure with four
hex-head capscrews (not shown) and lockwashers
(not shown). Install the fan belt.
13. Install clamps (19 and 24, Fig. 8A–4) on the radiator
input (upper) hose (25). Work the hose onto both the
engine and then the radiator. Tighten the clamps.
14. Install clamps (19 and 24) on the radiator return
(lower) hose (26). Work the hose onto both the
engine and then the radiator. Tighten the clamps.
Fill the cooling system. Run the engine to operating tem-
perature. Visually check for leaks with the engine run-
ning. Check the coolant level in the overflow bottle and
fill, or drain, as necessary.
8A.6 PERKINS ENGINE
ELECTRICAL SYSTEM
Refer to Section 10 Electrical System for information cov-
ering the Perkins engine electrical system, including the
starter, alternator and primary wiring.
8A.7 PERKINS ENGINE FUEL SYSTEM
The Perkins engine fuel system includes a fuel tank (item
36, Fig. 8A–7), fuel level sender (21) and dash panel
gauge, fuel strainer (8), fuel lift pump, fuel filter (14), and
fuel supply and return lines.
The threaded fuel filler (29) has a keyed fuel cap (31) and
permits entry of diesel fuel into the tank. The fuel level
sender (21) and dash panel gauge are described in Sec-
tion 10 Electrical System. A fuel supply hose (9) carries
fuel from the tank to the engine lift pump and then under
pressure to the fuel filter (14). Filtered fuel is directed to
the fuel injection pump and to the individual fuel injectors.
Surplus fuel at the fuel injector pump is returned to the
tank via the fuel return hose (15).
