3. Thoroughly clean junction of hydraulic lines and re-
lief valve manifold fittings.
4. Label all hydraulic lines for assembly purposes.
5. Disconnect hydraulic lines from manifold fittings.
Install caps or plugs in hoses, tube and manifold fittings
to prevent contamination and leakage of hydraulic oil.
6. Remove two (2) cap screws and flange nuts that se-
cure manifold to engine mount plate.
7. Remove relief valve manifold from machine.
8. If necessary, remove hydraulic fittings from manifold.
Discard removed O--rings.
9. If necessary, remove relief valve from manifold with
a deep well socket (Fig. 14). Note location of O--rings
and backup rings on valve. Remove and discard re-
moved seal kit.
Installation
1. If relief valve was removed from manifold, install re-
lief valve (Fig. 14):
A. Lubricate new O-rings and backup rings of seal
kit with clean hydraulic oil and install on cartridge.
The O-rings and backup rings must be arranged
properly on the cartridge valve for proper operation
and sealing.
IMPORTANT: Use care when installing the relief
valve. Slight bending or distortion of the stem
tube can cause binding and malfunction. Make
sure that deep well socket fully engages the
valve base.
B. Lubricate cartridge threads with clean hydraulic
oil. Thread cartridge valve carefully into correct man-
ifold port. The valve should go in easily without bind-
ing.
C. Torque cartridge valve using a deep well socket
to 25 ft- -lb (34 N- -m).
2. If fittings were removed from manifold, lubricate and
place new O--rings onto fittings (Fig. 10). Install and
tighten fittings into manifold ports (see Hydraulic Fitting
Installation in the General Information section of
Chapter 3 -- Hydraulic System).
3. Position relief valve manifold to engine mount plate
and secure with two (2) cap screws and flange nuts.

4. Remove caps and plugs from hoses, tube and mani-
fold fittings. Connect hydraulic lines to manifold (see Hy-
draulic Hose and Tube Installation in the General
Information section of Chapter 3 -- Hydraulic System).
5. Check oil level in the hydraulic tank and add correct
oil if necessary.
