ReferenceFor the correct procedure to check the steering time, refer to System Operation, Testing and Adjusting, "Steering Time - Check" for the machine that is being serviced.

Steering Time Adjustment
- Remove end cover (4) from steering control valve (1) .
- Add flow balance shims (2) in order to decrease the right turn time (steer faster) and increase the left turn time (steer slower). If the flow balance shims are removed, the result is opposite.
- Flow balance shims (2) are available in two thicknesses. The 5J-4776 Shims are 0.127 mm (0.0050 inch) thick. Two 5J-4776 Shims will change the steering time at high idle by approximately 0.5 second. The 4J-8224 Shims are 0.254 mm (0.010 inch) thick. Two 4J-8224 Shims will change the steering time at high idle by approximately 0.1 second.
- Install the end cover on the steering control valve.
Example: A check of the steering times shows that the right turn time is 0.4 second more than the left turn time. Flow balance shims (2) must be added to decrease the difference between the times.
The 4J-8224 Shims are 0.254 mm (0.010 inch) thick. Adding four 4J-8224 Shims will decrease the right turn time by approximately 0.2 second and increase the left turn time by approximately 0.2 second. The extra 4J-8224 Shims will make the right and left turn time approximately the same.
Cylinder Flow Adjustment
Ensure that both steering times (right and left) are 3.8 ± 0.2 seconds. If necessary, cylinder flow shims (3) can be added or removed.
- Remove the end cover from steering control valve (1) .
- Add shims (3) to decrease both steering times. If an increase in the steering times is required, remove shims.
One 4J-6806 Shims will change the steering times at high idle by approximately 0.1 second.
- Install the end cover on the steering control valve.
