Oil Cooler Removal (Fig. 88)
1. Before removing any parts from the hydraulic sys-
tem, park machine on a level surface, set brake, lower
attachment, and stop engine.
CAUTION
Operate all hydraulic controls to relieve system
pressure and avoid injury from pressurized hy-
draulic oil. Controls must be operated with the
ignition switch in OFF. Remove key from the igni-
tion switch.
2. Pivot seat up. Remove left and right side panels
from the machine. Remove left fender and seat (see Left
Fender (Seat Base) Removal in Chapter 6 – Wheels,
Brakes, and Miscellaneous).
3. Disconnect air hose from the air cleaner. Remove
lower shroud from the cooler mount. Disconnect control
rod from the pump lever (Fig. 89).
4. Clean around hydraulic fittings (36) on the oil cooler
(30). Disconnect hydraulic tube (37) and hose (28) from
the cooler. Allow fluid to drain into a suitable container.
5. Put caps or plugs on disconnected hydraulic hose
and tube to prevent contamination.
