Removal
Units prior to serial no. 314000001 use a separate hy-
draulic oil cooler. The hydraulic oil cooler on later units
is combined with the radiator assembly. It is not neces-
sary to drain the hydraulic system when removing the
radiator on early units prior to serial no. 314000001.
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch.
2. Open and remove engine hood from the machine.
CAUTION
Do not open radiator cap or drain coolant if the
radiator or engine is hot. Pressurized, hot cool-
ant can escape and cause burns. Ethylene- gly-
col antifreeze is poisonous. Dispose of coolant
properly, or store it in a properly labeled contain-
er away from children and pets.
3. Place a suitable container under the radiator to col-
lect the coolant. Open drain- cock valve, and completely
drain the radiator.
4. Remove glow plug relay from the radiator assembly.
Position relay away from the radiator.
5. Place a suitable container under the hydraulic filter
to collect the hydraulic fluid. The container should have
a 6 gal. (23 Ltr.) minimum capacity. Disconnect the hy-
draulic hose below the filter head or remove the hydraul-
ic filter element and drain the hydraulic system (Fig. 9).
6. Disconnect following hoses from the radiator or radi-
ator/oil cooler assembly:
A. Upper radiator hose to the water pump.
B. Lower radiator hose to the engine block.
C. Coolant hose to the expansion tank.
D. Air hose to the air cleaner.
7. For units serial no. 314000001 & up, disconnect the
following hoses from the oil cooler section of the radiat-
or/oil cooler assembly:
A. Hydraulic tube from top of hydraulic fluid cooler.
