4. Disconnectoneofthehydraulictubesfromtheteefit-
ting on bottom of reservoir to allow draining of 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 112 as a
guide.
7. If hydraulic fittings are to be removed from reservoir,

place newO--r ings ontofittings. Installfittings intoreser-
voir openings using marks made during the removal
process to properly orientate fittings. Torque fittings to
values identified in Figure 112.
2. Install reservoir using Figure 112 as a guide.
