(1) Three spacers will change the steering times at high idle by approximately 0.06 second.
(2) Three spacers will change the steering times at high idle by approximately 0.2 second.Adjustment Procedure
Steering Time Adjustment
Remove the end cover from steering control valve (1).
Add flow balance shims (3) 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.
The 8B-3115 Shim are 0.25 mm (0.01 inch) thick. Two 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 (3) must be added to decrease the difference between the times.The addition of four shims will decrease the right turn time by approximately 0.2 second and increase the left turn time by approximately 0.2 second. The addition of four shims will make the right and left turn time approximately the same.Cylinder Flow Adjustment
Both steering times (right and left) must be 3.8 0.2 seconds. If not, cylinder flow shims (2) must be added or removed.
Remove the end cover from steering control valve (1).
Add shims (2) to decrease both steering times. If an increase in the steering times is required, remove shims. The 8M-8211 Spacer are 0.25 mm (0.01 inch). Three shims will change the steering times at high idle by approximately 0.06 second.The 7M-8538 Spacer are 0.91 mm (0.0358 inch). Three shims will change the steering times at high idle by approximately 0.2 second.
Install the end cover on the steering control valve.
