1. Relay assembly
2. Main hydraulic manifold
5. Remove the relay mounting plate from the dash frame without disconnecting
any of the relays from the wire harness. Move the relay assembly to one side.
6. Thoroughly clean the main hydraulic manifold and plug at the G3 port.
7. Remove the plug from the G3 port of the main manifold and install a size 6
SAE-ORB (9/16–18) diagnostic connector and cap (Toro part nos. 59–7410
and 354–79).
8. Connect a 34,475 kPa (5000 PSI) pressure gauge with hydraulic hose
attached to test fitting in port G3 port of main manifold.
9. Start engine and idle at low speed. Check for hydraulic leakage at test
connection and correct any issues before proceeding with test.
10. Increase engine speed to 2300 RPM.
Hold steering wheel at full lock only long enough to get a system
pressure reading. Holding the steering wheel against the stop for an
extended period may damage steering components.
11. Turn steering wheel all the way in one direction (turning to the right shown)
and momentarily hold the steering wheel against resistance.
Gauge reading should be approximately: 21,373 kPa (3100 PSI)
12. Release steering wheel, stop engine and record test results.
13. If steering relief pressure reading is incorrect:
