Step 2. Check input pressure at hydraulic motor.
If pressure to motor is 4500 to 5000 psi (31026 - 34474 kPa), go to step 3.
If pressure to motor is not 4500 to 5000 psi (31026 - 34474 kPa), go to fault symptom #2.
Step 3. Check return hose from hydraulic motor to hydraulic tank.
If hose is crimped, damaged, or leaking, replace hose (para 4-136).
If hoses are not crimped, damaged, or leaking, go to step 4.
Step 4. Check return pressure from hydraulic motor.
If return pressure is not 4500 to 5000 psi (31026 - 34474 kPa), replace and repair hydraulic
motor (para 5-48).
If return pressure is 4500 to 5000 (31026 - 34474 kPa), go to step 5.
Step 5. Inspect return filter in hydraulic tank.
If filter is clogged, clean or replace filter (para 4-144).
If filter is not clogged, fault not corrected. Notify supervisor.

HYDRAULIC VARIABLE-SPEED PUMP DOES NOT OPERATE.
Step 1. Inspect transmission cable.
If cable is broken, bent, or crushed, replace transmission cable (para 4-94).
If cable is free from damage, go to step 2.
Step 2. Inspect transmission control lever and linkage.
If linkage does not operate correctly, replace transmission control lever and linkage (para 4-
93).
If linkage operates correctly, go to step 3.
Step 3. Inspect feed and return hoses from hydraulic tank to hydraulic variable-speed pump.
If hoses are crimped, damaged, or leaking, replace hoses (para 4-136).
If hoses are not crimped, damaged, or leaking, go to step 4.
