2584766 - 4450A10 front wheel geometry - check using optical equipment - includes front wheel tow-in adjustment if necessary

    Op. 7055B54 PROTECTION/GUARD UNDER ENGINE - R.R.The front wheel geometry should be checked after having subjected the components which affect the wheel geometry to the following checks:tyre inflation pressure;the eccentricity and the orthogonality of the wheel rims should not exceed 3 mm;wheel bearings end float;clearance between steering knuckle and track control arm ball joint;steering rod ball joint clearance.Toe-in check:Carry out the preliminary checks on the vehicle and remove any loads transported.Position the vehicle (in running order) on the lift with test equipment.Check that the toe-in (1a-1b) is within the recommended limits.The toe-in values refer to a vehicle in standard 0 and standard A.Standard 0 = unladen vehicle including spare wheel, tools, accessories and fluids (with 5 litres of fuel).Standard A = unladen vehicle including spare wheel, tools, accessories and suppiles (full fuel tank).

.
If the toe-in is not within the recommended limits, adjust it following the instructions given below.
Toe-in adjustment:Straighten the steering wheel and lock it in position using a suitable tool.Loosen the bands securing the boots to the steering rods.Loosen the nuts securing the adjustable steering rods.Tighten or loosen the steering box rods until the toe-in value is correct, keeping the front wheels aligned.

Tighten the bands for the boots on the steering rods.Remove the steering lock.Remove the vehicle from the lift with the test equipment.
Caster check:The front wheel caster cannot be adjusted. If the value measured is not within the recommended limits, check the suspension track control arm and the bodyshell.
Carry out the preliminary checks on the vehicle and remove any loads transported.Position the vehicle (in running order) on the lift with test equipment.Check that the front wheel caster is within the recommended limits.The camber figures refer to a vehicle in standard 0 and standard A.Standard 0 = unladen vehicle including spare wheel, tools, accessories and fluids (with 5 litres of fuel).Standard A = unladen vehicle including spare wheel, tools, accessories and suppiles (full fuel tank).
