Oil Cooler Installation (Fig. 88)

1.Make sure both hydraulic openings to the oil cooler are clean. Remove plugs from the cooler openings.

2.Reinstall O–rings and 90o hydraulic fittings to the oil cooler. Torque fittings from 36 to 40 ft–lb (5.0 to 5.5 kg–m).

3.Secure oil cooler to cooler mount (25) with rubber clamps (35), socket head screws (27), and T–nuts (34).

4.Position cooler mount (25) and oil cooler (30) to the frame. Secure upper front portion of the mount to the frame with both cap screws (42) and lock nuts (23).

5.Secure lower portion of the cooler mount (25) to the frame with three self tapping screws (26).

NOTE: Apply antiseize lubricant or to the threads of cap screws prior to installation.

6.Make sure grommets (19) are installed into cooler mount (25). Secure hydraulic tank (40) to the to the mount with three cap screws (21) and flat washers (20). Torque cap screws from 30 to 60 in–lb (35 to 69 kg–cm).

7.Remove wire securing hydraulic tank (40) to the frame.

CAUTION

One person should operate the chain fall or hoist while the other person guides the engine into the frame.

8. Reinstall engine and hydrostat as follows:

IMPORTANT: When repositioning the engine and hydrostat to the frame, make sure not the damage the cooling fan, wires, hoses, and cables.

A.Use jack or chain fall to position the front engine mounts and engine support to the frame.

B.Secure engine mount to the frame with four cap screws and flat washers (Fig. 48).

C.Secure front engine mounts to the frame with cap screws, flat washers, and lock nuts (Fig. 90).

D.Remove jack or chain fall from the engine base.

9.Remove caps or plugs on disconnected hydraulic hose (28) and tube (37).

10.Make sure hydraulic fittings (36) on the oil cooler (30) are clean. Connect hydraulic tube (37) and hose

(28) to the cooler.

11.Connect air hose to the air cleaner. Remove lower shroud to the cooler mount. Connect control rod to the pump lever (Fig. 89).

12.Install left fender and seat (see Left Fender (Seat Base) Installation in Chapter 6 – Wheels, Brakes, and Miscellaneous). Install left and right side panels to the machine.

13.Fill hydraulic tank (40) with hydraulic fluid (see Check Hydraulic System Fluid).

14.Charge hydraulic system (see Charge Hydraulic System).

Hydraulic Tank Removal (Fig. 88)

1.Disconnect oil cooler (40) and cooler mount (25)

from the frame (see Oil Cooler Removal). Do not re- move 90o hydraulic fittings (36) from the cooler.

2.Drain hydraulic tank (40) by removing drain plug

(39). Allow hydraulic fluid to drain into a suitable contain- er. Install plug back to tank.

3.Remove both hydraulic hose (28) and tube (37) from both 90o hydraulic fittings (36) on the tank.

4.Remove wire securing hydraulic tank to the frame. Remove tank from the frame.

Hydraulic Tank Inspection (Fig. 88)

1.Clean hydraulic tank (40) and filler screen (4) with solvent.

2.Inspect hydraulic tank (40) for leaks, cracks, or oth- er damage.

3.Replace hydraulic hose (37) or tube (37) if worn or leaking.

Hydraulic Tank Installation (Fig. 88)

1.Position hydraulic tank (40) to the frame. Secure tank to the frame with a flexible wire.

2.Secure hydraulic hose (28) and tube (37) to both 90o hydraulic fittings (36) on the tank.

3.Connect oil cooler (40) and cooler mount (25)to the frame and hydraulic tank (40) (see Oil Cooler Installa- tion).

4.Start machine. Run engine at lowest idle speed for 3 to 5 minutes to circulate hydraulic fluid and remove any air trapped in the system. Stop machine and recheck hy- draulic tank level.
