Checking Steering Pressure

Steering pressure is also checked at either one of the pressure diagnostic couplers (Figure 48) under the right grill guard. Check steering pressure at either coupler with a 300-600 PSI gauge.

WARNING

DO NOT depress the FOOT PEDAL with the 300-600 PSI gauge installed or the gauge will be ruined.

Figure 48. Steering Pressure Gauge

Run the engine at full RPM. The steering system's factory settings are shown in Table 9, however some operators may prefer a more responsive steering (higher pressure required) and some operators may prefer a "softer feel" (lower pressure required).

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 49).

3.Loosen 1-1/16" jam nut on charge relief valve.
