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.

CAUTION

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

STX-SERIES — MAINTENANCE

(Table 4) indicates proper steering pressure. Check with engine at Full Speed.

Table 4. Steering Pressure

Checked With Engine at Full Speed

Cool Oil

200-250 PSI

Hot Oil

180-200 PSI

Run the engine at full RPM. The steering system's factory setting is as shown in Table 4, 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 27).

3.Loosen 1-1/16" jam nut on charge relief valve (Item A, Figure 28).

4.Use a 1/2" socket to adjust the small hex nut within the larger hex jam nut (Item B, Figure 28).

5.Adjust to proper steering pressure specifications shown in Table 4.

6.Retighten jam nut, remove gauge, and reinstall grill guard.
