Removal (Fig. 126)
1. Park machine on a level surface, lower cutting
decks, stop engine, engage parking brake and remove
key from the ignition switch.
2. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
3. To prevent contamination of hydraulic system during
hydraulic reservoir removal, thoroughly clean e xterior of
reservoir.
4. To allow draining of hydraulic reservoir, disconnect
the hydraulic hose (item 23) from the fitting in the bottom
of the reservoir. Drain reservoir into a suitable container.
5. Disconnect remaining hydraulic hoses from reser-
voir. Label the hydraulic hoses to show their correct
position on the reservoir for assembly purposes.
6. Remove hydraulic reservoir using Figure 126 as a
guide.
7. If necessary, remove fittings from reservoir and dis-
card O--rings.
Inspection
1. Clean hydraulic reservoir and suction strainer with
solvent.
2. Inspect reservoir for leaks, cracks or other damage.
Installation (Fig. 126)
1. If fittings were removed from reservoir, lubricate and
place new O--rings onto fittings. Install fittings into reser-
voir openings. If reservoir strainer (item 7) was removed
from reservoir, torque strainer from 35 to 47 ft--lb (48 to
63 N--m).
2. Install reservoir using Figure 126 as a guide.
IMPORTANT: When tightening hoses to reservoir
fittings, hold fitting with wrench to prevent over--
tightening of fitting and potential reservoir damage.
3. Connect hydraulic hoses to reservoir fittings (see
Hydraulic Hose and Tube Installation in the General In-
formation section of this chapter).
4. Fill reservoir with hydraulic fluid to proper level.
