STEP
2.
Perform No. 1 actuator oil flow and hydraulic pressure test.
NOTE
Have suitable container ready to catch oil.
a.
Stop engine; relieve hydraulic pressure.
b.
Disconnect No. 1 SPNSN UNIT- #9 hose (Figure 2, Item 2) at elbow (Figure 2, Item 6) on port 9
(Figure 2, Item 7) of No. 1 actuator (Figure 2, Item 4).
c.
Cap elbow (Figure 2, Item 6).
d.
Connect tee (Figure 2, Item 1), globe valve (Figure 2, Item 8), and pressure measuring device
(Figure 2, Item 3) to end of No. 1 SPNSN UNIT-#9 hose (Figure 2, Item 2).
e.
Connect a drain hose (Figure 2, Item 5) to open end of globe valve (Figure 2, Item 8).

g.
Observe for flow of oil.
CONDITION/INDICATION
Does oil flow freely?
DECISION
YES - Go to Step (3).
NO - Go to Step (10).
STEP
3.
Close globe valve and check hydraulic pressure.
Close globe valve (Figure 2, Item 8) and measure pressure on pressure measuring device
(Figure 2, Item 3).
CONDITION/INDICATION
Is hydraulic pressure greater than 2,500 psi (17,238 kPa)?
DECISION
YES - Go to Step (4).
NO - Go to Step (10).
STEP
4.
Check for blockage at port 9.
CONDITION/INDICATION
Is port 9 blocked?
