Removing the Hydraulic Tank (continued)
3. Remove the brake handle from the machine to allow removal of the hydraulic
tank; refer to Parking Brake Assembly (page 6–15) .
4. Drain the hydraulic fluid from the hydraulic tank.
5. Clean the hydraulic hose ends and fittings on the hydraulic tank to prevent
contaminants from entering into the hydraulic system.
6. For assembly purposes, label all the hydraulic hoses and fittings. Remove
the hydraulic hoses from the fittings on the hydraulic tank and drain the
hoses into a suitable container.
7. Install clean caps or plugs on the hydraulic hoses and fittings to prevent
system contamination.
8. Remove the 2 washer-head screws and tank support that retain the hydraulic
tank to the frame.
9. Remove the hydraulic tank toward the front of the machine.
10. Inspect the foam strips under the hydraulic tank.
Note: Replace the strips if they are damaged.
11. Remove the fittings from the hydraulic tank as shown in Figure 54 . Discard
and replace the O-rings.
Inspecting the Hydraulic Tank
1. Clean the hydraulic tank and suction strainer with solvent.
2. Inspect the hydraulic tank for leaks, cracks, or other damage.
Installing the Hydraulic Tank
1. If the suction strainer was removed from the hydraulic tank, install a new,
lubricated O-ring on the strainer. Thread the strainer into the tank and torque
the strainer to
82 to 90 N∙m (60 to 66 ft-lb) .
2. Install the fittings that were removed with new lubricated O-rings to the
hydraulic tank ( Figure 54 ). Refer to Installing the Hydraulic Fittings (SAE
Straight Thread O-Ring Fitting into the Component Port) (page 4–7) . Tighten
the fittings to 90 to 94 N∙m (66 to 70 ft-lb)
3. Install the hydraulic tank to the machine and secure the tank to the frame
with the tank support and 2 washer-head screws.
4. Remove the caps or plugs that were installed to the hydraulic hoses and
fittings during the removal process.
5. Use the labels that you attached during tank removal to correctly connect
the hydraulic hoses to the fittings on the hydraulic tank; refer to Installing the
Hydraulic Hose and Tube (O-Ring Face Seal Fitting) (page 4–5) .
6. Install the brake handle to the machine; refer to Parking Brake Assembly
(page 6–15) . Ensure that the operation of the parking brake sensor is correct
after you install the brake handle.
7. Fill the hydraulic tank with the correct quantity of new hydraulic fluid.
8. Install the operator seat and seat base; refer to Installing the Operator Seat
(page 6–36) .
9. Operate the machine. Check the hydraulic-fluid level and adjust if necessary.
10. Check the hydraulic components for leaks. Tighten any loose connections.
