Pre-Adjustment Testing
- On all models, connect a pressure gauge between steering pump and steering gear. See Fig 1
. Ensure reservoir is full. Place pressure gauge so it can be seen from driving position.

- On 700 series vehicles, remove steering wheel impact guard by lifting lower edge and pulling out. On all other models, remove by compressing sides slightly. On all models, install a torque wrench on steering wheel nut.
- With engine at idle and using a torque wrench, turn steering wheel slowly to the right. Read torque when pressure reaches 171 psi (12 kg/cm2
) on cam gear-type, 285 psi (20 kg/cm2
) for ZF-type steering gear assembly.
- Turn wheel to left. Torque should be 31-40 INCH lbs. (3.5-4.5 N.m) as gear approaches specified pressure. Difference between both sides must not exceed 9 INCH lbs. (1 N.m) on cam gear-type. Difference must not exceed 4.4 INCH lbs. (.5 N.m) on ZF steering gear.
- If difference exceeds specifications on 700 series vehicles, the steering gear must be rebuilt or a new one installed. If proper specifications cannot be obtained on cam gear-type pumps, see CAM GEAR-TYPE ADJUSTMENT
in this article.
