FRONT CORNER (LEFT OR RIGHT) DOES NOT RAISE IN SPRUNG OR UNSPRUNG MODE - Continued
Is transducer T-5 (right) and T-6 (left) hydraulic pressure greater than 2,500 psi (17,238 kPa)?
YES - Go to Step (3)
NO - Replace No. 1 actuator (TM 5-2350-262-20).
Determine if there is excessive internal leakage from No. 1 actuator by checking if front corner will raise in both
SPRUNG and UNSPRUNG mode.
Have suitable container ready to catch oil.
Disconnect NO 1 SPNSN UNIT-2 hose (Figure 2, Item 4) from elbow (Figure 2, Item 3) at port 2
(Figure 2, Item 2)on No. 1 actuator (Figure 2, Item 1).
Cap elbow (Figure 2, Item 3) and plug hose (Figure 2, Item 4).
No. 1 Right Actuator Depicted.
Have assistant start engine and move SPRUNG/UNSPRUNG lever to SPRUNG. Observe that corner of
