In-Vehicle Adjustments & Repairs
VALVE SPOOL CENTERING CHECK
The ``out-of-car'' procedure for valve centering check is the same as for the ``in-car'' except the torque and simultaneous pressure reading must be
made at the right and left stops instead of either side of center.
1.
Install a 2000 psi pressure gauge in pressure line between pump outlet port and steering gear inlet port. Make sure that valve on gauge in is fully
open position.
2.
Check fluid level in reservoir and replenish as required.
3.
Start engine and cycle steering wheel from stop-to-stop to bring steering lubricant up to normal operating temperature. Stop engine and recheck
reservoir. Add fluid as necessary.
4.
With engine running at a fast idle speed (1000 RPM) and steering wheel centered, attach an inch-pound torque wrench to steering wheel retaining
nut. Apply sufficient torque to wrench in each direction (either side of center) to get a gauge reading of 250 psi.
5.
The torque reading should be the same in both directions. If the difference between readings exceed 4 inch lbs., the shaft and control assemblies
must be replaced.
