2. Run the engine at test rpm.
3, Slowly close the manual load valve to get 1000
psi pressure.
4. Write down the flow rate (gpm).
Test 38: System Oil Temperature
1, Open the manual load valve fully.
2. Run the engine at any rpm with the system
pressures at 0 to 100 psi.
3. Move the steering wheel to the RIGHT TURN
position.
4. Write down the oil temperature.
WARNING: All pressure in the lines must be
released or injury to
personnel
and
damage
to
equipment can result while loosening the lines to install
or remove the plate assemblies.
Find the leakage rates for the right and left cylinders.
Use the test information from System Test, Pump Test
and Blocked Cylinder Tests. Example: Find the leakage
rate for the steering cylinders.
Test 27: flow rate of pump and control valve.
Test 35: flow rate of pump, control valve and left
side cylinder.
Test 4: flow rate of pump, control valve and both
cylinders.
The system components tested in Tests 27 and 35
are the same except for the left side cylinder. Then the
difference in flow rates must be the leakage in the left
side cylinder (take the test information for Test 35 away
from the test information for Test 27).
The system components tested in Tests 35 and 4
are the same except for the right side cylinder. Then the
difference in flow rates must be the leakage in the right
side cylinder (take the test’ information for Test 4 away
from the test information for Test 35). Make a
comparison of the test values with the values on Chart C.
Troubleshooting
PROBLEM: Leakage is in right steering cylinder.
PROBABLE REASON:
A. Piston seals are worn.
B. Loose piston nut.
C. Damage in cylinder assembly.
RECOMMENDATION FOR ACTION:
Disassemble and make repairs to the right steering
cylinder.
PROBLEM: Leakage is in left steering cylinder.
PROBABLE REASON:
A. Piston seals are worn.
B. Loose piston nut.
C. Damage in cylinder assembly.
RECOMMENDATION FOR ACTION:
Disassemble and make repairs to the left steering
cylinder.
