Steering Gear: Adjustments
Rotary Valve Centering Inspection
1. Install a 2000 psi pressure gauge in pressure line between pump outlet port and steering gear inlet port. Make sure valve on gauge is in 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. Torque reading should be the same in both directions. If difference between readings exceeds 6 in lb, remove steering gear from vehicle and
replace shaft and control assembly. The "out-of-vehicle" procedure for centering check is the same as for the "in-vehicle" except torque and
simultaneous pressure reading must be made at right and left stops instead of either side of center.
