To check the pressure setting for the steering system:1. Remove plug (1) and install a 0 to 4000 psi pressure gauge.
Steering Control Valve
(1) Plug.2. Install anti-pivot link (2) so the machine can not turn. If the anti-pivot link can not be installed, the pressure setting can be checked by an adjustment of the striker (stud assembly) that is not correct. This lets the front and rear frame stops come in contact.
Anti-Pivot Link Installed
(2) Anti-pivot link.3. Start the engine and operate it at high idle.4. Turn the steering wheel until the relief valve opens. Note the indication on the gauge. The correct relief pressure is 17 240 520 kPa (2500 75 psi).If the pressure is not correct:a. Remove plug (4) from steering control valve.
Steering Control Valve
(3) Shims. (4) Plug.b. Add shims (3) to increase the pressure setting and remove shims if a decrease is necessary. Steering Slip Check
To check the steering wheel slip:1. Put the machine on a dry hard surface. Raise the bucket and release the brakes.2. With the engine at low idle, turn the steering wheel slowly through one revolution so that there is a minimum of articulation. Do this in both directions to get the feel of the steering action.3. Do this test three more times in each direction. Make a note of the time required for each of the revolutions of the steering wheel.4. Add the three times for each direction. If these totals are 60 seconds or more, the slip is acceptable.5. If the totals are less than 60 seconds, remove the spool from the main control valve. Turn the spool around in its bore (turn end for end). To do this the spring, retainer, and shims must be installed on the opposite end of the spool. On some machines this will correct the problem of manufacturing tolerances and the slip will then be acceptable.Pivot Pin Bearing Adjustment
Upper And Lower Pivot Pins
(1) Cover assembly. (2) Bolts. (3) Bearing cap. (4) Shims. (5) Bearing cap. (6) Bearing cap. (7) Shims. (8) Bearing cap. (9) Bolts. (10) Plate. (11) Shims. The original thickness of shims (4) or (7) can be used again if the bearings were the only parts replaced. If any of the caps (3), (5), (6) or (8) are replaced, the bearing adjustment must be checked.Upper Pin Adjustment

Install three bolts (12) to hold lower cap (5) in place. Keep an equal space between each of the bolts. Install the lower cap without the seal. This will give the clearance necessary for the tooling.3. Install the lower bearing cup. Make sure that the cup comes in contact with lower cap (5).
