Oil Cooler
Removal (Figs. 113 and 114)
1. Parkmachineonalevelsurface, lower cutting deck
(or implement), stop engine, engage parking brake and
remove key from the ignition switch.
2. Raise hood and secure it in the raised position.
CAUTION
The radiator and oil cooler may be hot. To avoid
possible burns, allow the engine and cooling
systems to cool before workin g on th e oil cooler.
3. Thoroughly clean hydraulic hose ends and oil cooler
fittings to prevent hydraulic system contamination. La-
bel hydraulic hoses for assembly purposes.
4. Remove hydraulic hoses from oil cooler. Install clean
plugs in hose openings to prevent contamination. Re-
move and discard O- rings from oil cooler fittings.
5. Rotate clamp and tilt oil cooler from radiator frame.
Slide left side of oil cooler from radiator frame by aligning
roll pin in cooler mount with slot in radiator frame. Then,
remove right side of coolerfromradiatorframe.
Inspection
1. Back flush o il cooler with cleaning solvent. Make
sure all solvent is drained from the cooler.
CAUTION
Use eye protection such as goggles when using
compressed air to dry oil cooler.
2. Dry inside of oil cooler using compressed air in the
opposite direction of the oil flow.
3. Install clean plugs on oil cooler ports. Thoroughly
clean exterior of cooler.
4. The oil cooler should be free of corrosion, cracked
tubes or excessive pitting of tubes.
Installation (Figs. 113 and 114)
1. Install right side mount o f oil cooler through hole in
radiator frame. Then, slide left side cooler mount into ra-
diator frame by aligning roll pin and slotted hole in radia-
tor frame. Tilt cooler to radiator frame and secure with
clamp.
2. Lubricate and place new O- rings in oil cooler ports.
Remove plugs from hydraulic hoses. Connect hydraulic
hoses to oil cooler using labels placed during removal
(see Hydraulic Hose and Tube Installation in the Gener-
al Information section of this chapter).
3. Make sure hydraulic tank is full. Add correct oil if nec-
essary.
4. Lower and latch hood.
