STEERING PRESSURE TEST
1. On the manifold block, install a 5,000 psi pressure
gauge into quick disconnect test port 1 (Figure 31).
2. Start the engine and run at full throttle.
3. Turn the steering wheel to the left or right (maximum)
and hold. Read the steering relief pressure. The relief
pressure reading for the steering test port 1 will be 700
psi. Again, under normal operating conditions, pressure
for the steering port will be between 200-400 psi.
4. If maximum pressure cannot be reached, plug the
steering cylinder pressure hoses and retest. If pressure
is correct, the steering cylinder is leaking. DO NOT
ACTIVATE THE VIBRATION FUNCTION WHILE
PERFORMING THIS TEST!

NOTICE
Vibration relief pressure is hard to read accurately using
this test. It may be necessary to disconnect the pressure
line to the vibration drive motor. Plug this line and retest,
pressure will be exact relief pressure.
DO NOT
perform
this test for a long period of time — damage could occur.

STEERING RELIEF VALVE PRESSURE ADJUSTMENT
To adjust the relief valve steering pressure perform the
following:
1. Insert an 8 mm allen wrench into steering relief port 4
(Figure 36) on the manifold block.

2. On the manifold, connect at 5,000 psi pressure gauge
into quick disconnect test port 1.
3. Start the engine and run at full throttle.
4. Turn the steering wheel to the left or right (maximum)
and hold. Read the steering relief pressure. The relief
pressure reading for the steering test port 1 will should
be 700 psi.
5. If the steering relief pressure is not 700 psi, using the
allen wrench adjust the pressure at port 4 until the
pressure gauge reads 500 psi.
