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 the engine and idle at low speed. Check for hydraulic leakage at test
connection and correct any issues before proceeding with test.
10. Select A L mode and increase engine speed to 2300 RPM.
UTO OW
Hold paddle switch at full raise position only long enough to get a
system pressure reading. Holding the paddle switch at full raise
position for an extended period may damage lift circuit components.
11. Raise the hitch cylinders all the way up and momentarily hold the paddle
switch in the raise position.
Gauge reading should be approximately: 22,063 kPa (3200 PSI)
Note: Machine fault C153C may appear during testing as there will be no
hitch movement while lift valve (SP1) is energized.
