21.
HYDRAULIC FLUID TEMPERATURE IS TOO HIGH (CONT).
Step 3. Inspect hydraulic fluid cooler.
If hydraulic fluid cooler is damaged or leaking, clean/replace hydraulic fluid cooler (para 4-
139).
If hydraulic fluid cooler is not damaged or leaking, fault not corrected. Notify supervisor.
22.
ALL HYDRAULIC CYLINDERS DO NOT OPERATE.
Step 1. Inspect pressure and return hoses to hydraulic valve bank assembly.
If hoses are crimped, damaged or leaking, replace hose(s) (para 4-136).
If hoses are not crimped, damaged or leaking go to step 2.
WARNING
Hydraulic fluid is very slippery and can cause falls. To avoid injury, wipe up
spilled fluid with rag.
Step 2. Check input pressure at valve bank assembly.
If input pressure is below 1700 to 1800 psi (11721 - 12410 kPa), go to fault symptom #3.
If input pressure is 1700 to 1800 psi (11721 - 12410 kPa), replace/repair valve bank assembly
(para 4-134/5-49).
23.
ONE HYDRAULIC CYLINDER DOES NOT OPERATE.
Step 1. Check control valve for the inoperative cylinder, on the control valve assembly (para 4-134).
If control valve is inoperative, replace/repair hydraulic manifold (para 4-133).
If control valve is not inoperative, go to step 2.
