STEERING FLOW METER TEE TEST PROCEDURES - CONTINUED
0306 00
SYSTEM TEST - CONTINUED
NOTE
System base flow rate will be the same as the low pressure flow reading of the hydraulic implement pump.
4.
Steer Right Flow Rate (Leakage Rate).
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 1. Correct steer right flow rate is 51 gpm.
Steer Left Flow Rate (Leakage Rate).
5.
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.
f.
Refer to Table 1. Correct steer left flow rate is 51 gpm.
System Oil Temperature (Finish).
6.
a.
Open the manual load valve on the flow meter fully.
b.
Start engine. Turn the steering wheel right and hold.
c.
Record oil temperature. Refer to Table 1. System oil temperature should be 145-155F (63-68C).
COMPARISON OF TESTS
1.
Test reading is higher or lower than maximum pres-
sure relief valve setting (Test 1) and the percent flow
(PARTIALLY HIDDEN)
loss (Tests 4 and 5) is different by 15 to 50 percent.
Check the relief valve. Refer to Steering Control Valve
oil pressure, or is damaged or defective, service or replace.
