Servo Balance

On all models, raise front wheel off ground. Connect pressure gauge between steering pump and steering gear. See Fig 1 . Ensure reservoir is full. Place 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 others, remove by compressing sides slightly. On all models, place 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.
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, the steering gear must be rebuilt or replaced.

NOTE: All other steering gear adjustments are covered under overhaul procedures.
