FORWARD LEFT MANIFOLD FUNCTIONALITY TESTING

CAUTION

Testing should be performed in a clean environment and protective dust covers or caps

should be installed on all openings to prevent contamination. Dirt can damage parts and

cause malfunctions.

NOTE

Prior to installing the primary manifold in vehicle, the following functionality tests should

be performed.

NOTE

Steps a through c apply to Figure 4--3.

Testing of hydraulic circuit port 9 (top of manifold) connected to two port 9’s on either side of the

manifold.

1. Connect --6 pressure hose with 37

flare fitting to port 9 (top of manifold).

2. Pressurize the port 9 hose to 1000 psig (6894.757 kilopascal) and a flow of approximately 5

GPM (18927.06 CPM) and verify flow is exiting from the other two port 9 fittings on the sides of

the manifold, and that there is no fluid flowing from any other manifold ports.

3. De--pressurize hose and disconnect from port 9.

Testing hydraulic circuit port 3L (side of manifold) to port 3L on the opposite side of the manifold.

1. Connect --8 pressure hose with 37

flare fitting to port 3L on either side of the manifold.

2. Pressurize the port 3L hose to 1000 psig (6894.757 kilopascal) and a flow of approximately 5

GPM (18927.06 CPM) and verify flow is exiting from the port 3L fitting on the other side of the

manifold and there is no other fluid flowing from any other manifold ports.

3. De--pressurize hose and disconnect from port 3L.
