Installation (Fig. 67)
1. If fittings were removed from manifold:
A. Lubricate new o--rings with clean hydraulic oil.
Install lubricated o--rings on fittings.
B. Install fittings into manifoldopenings using marks
made during the removal process to properly orien-
tate fittings.
C. Refer to Figure 68 for straight fitting installation
torque. For information on tightening procedures for
adjustable fittings, see Hydraulic Fitting Installation
in the General Information section of this chapter.
2. Refer to Figure 68 for check valve, shuttle valve and
plug installation torque.
3. Position flush manifold to the frame and secure with
two (2) cap screws and flange nuts.
4. Remove caps and plugs from fittings and hoses.
Properly connect hydraulic lines to manifold (see Hy-
