BLOCKED CYLINDER TEST (ALL CYLINDERS BLOCKED) - CONTINUED
3.
Steer Left Flow Rate (Leakage).
a.
Turn the steering wheel left and hold.
b.
Open the manual load valve on the flow meter fully.
c.
Start engine and run at 1,900 RPM.
d.
Slowly adjust the manual load valve on the flow meter to a pressure of 1,000 psi (6,895 kPa).
e.
Record flow rate. Refer to Table 2. Correct steer left flow rate is 52 gpm.
4.
System Oil Temperature.
a.
Turn the steering wheel right and hold.
b.
Open the manual load valve on the flow meter fully.
c.
Start engine and run at 1,900 RPM.
NOTE
Before recording test data, make sure the system pressure is at least 100 psi (689 kPa).
d.
Record oil temperature. Refer to Table 2. System oil temperature should be 145-155F (63-68C).
COMPARISON OF TESTS
1.
Steer right flow rate (Test 8) and steer left flow rate (Test 9) indicate leakage in one or more cylinders.
a.
Check the steering cylinder.
(1)
If the steering cylinder or steering cylinders are leaking, go to Test 12.
2.
Steer right flow rate (Test 8) and steer left flow rate (Test 9) indicate leakage in valves.
a.
Check the relief valve.
(1)
If the relief valve opens at a low oil pressure, or is damaged or defective, service or replace. Refer to Steer-
ing Control Valve Maintenance (WP 0312 00).
