Checking Steering Pressure
Steering pressure is also checked at either of the high pressure
diagnostic couplers under the right grill guard. Check steering
pressure at either coupler with a 300-600 PSI gauge.
Run the engine at full RPM. The steering system's factory setting
is as shown in Table 5, however some operators may prefer a
more responsive steering (higher pressure required) and some
operators may prefer a "softer feel" (lower pressure required).
DO NOT depress the FOOT PEDAL with the 300-600 PSI
gauge installed or the gauge will be ruined.
(Table 5) indicates proper steering pressure. Check with engine
at Full Speed.
Steering Pressure Adjustment
Remember, DO NOT depress the foot pedal with the 300-600
PSI gauge installed. Immediate damage to the gauge will occur.

1. Remove right grill guard.
2. Install 300 or 600 PSI gauge (Figure 42).
3. Loosen 1-1/16" jam nut on charge relief valve (Item A,
Figure 43).
4. Use a 1/2" socket to adjust the small hex nut within the
larger hex jam nut (Item B, Figure 43).
5. Adjust to proper steering pressure specifications shown in
