TEE TEST PROCEDURE FOR STEERING SYSTEM (CONT)
(Sheet 21 of 24)
Turn to right.
Run at any rpm with system pressure at 0 to
100 psi (70.3 kgs/sq. meter).
Find the leakage rate of the cylinders and the
leakage rate of the control valves. Use the test
information from the System Tests, Pump Test
and Blocked Cylinder Tests.
Example: Find the leakage rates in the RIGHT
Test 8: flow rate of the pump only.
Test 20: flow rate of pump and control valve.
Test 4: flow rate of pump, control valve and
The system components tested in Tests 8 and
20 are the same except for the control valve.
Then the difference in flow rates must be the
leakage in the control valve. (Subtract the in-
formation for Test 20 from the test information
for Test 8.
