0306 00
BLOCKED CYLINDER TEST (RIGHT SIDE CYLINDER BLOCKED)
WARNING
Before installing blocking plate, install a safety link. Move the steering wheel to the right and then to the left
several times to release any pressure in the steering cylinder lines. Failure to follow this procedure may
cause injury. If you are injured, seek medical attention immediately.
Install blocking plate assembly in the rod end of the right steering cylinder.
1.
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 system oil temperature. Refer to Table 2. System oil temperature should be 145-155F (63-68C).
2.
Steer Right Flow Rate (Leakage).
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.
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 right flow rate is 51-52 gpm.
3.
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, ensure system pressure is at least 100 psi (689 kPa).
d.
Record system oil temperature. Refer to Table 2. System oil temperature should be 145-155F (63-68C).
COMPARISON OF TESTS
