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.
