Wheel, Balancing With Fine Balancing Machine (Finish Balancer)
Tension the wheel on balancing machine
Be careful not to scratch off the glued- on wheel trim on these rims.
The surface of the wheel trim is very sensitive.
The rim will have be replaced if the wheel trim is damaged.
The wheel trim cannot be replaced.
Working with a Fine Balancing Machine requires instruction from the manufacturer of the balancer.
When balancing, place the wheels of the driven axle on the turntable sensors. On a FWD vehicle, the front wheels must be on the sensors. On AWD vehicles, all four wheels must be on the sensors.
If it is determined when balancing on the vehicle the residual imbalance is more than 20 grams, the wheel should be rotated on the wheel hub.
-- Mark the point at which the imbalance is indicated.
-- Afterwards, unbolt the wheel and rotate its position on the wheel hub so that the marked positions point downward.
The wheel hub must not turn during this procedure.
-- First, tighten the lowest wheel bolt hand-tight to approximately 30 Nm.
-- Tighten the remaining wheel bolts diagonally to approximately 30 Nm. This process centers the wheel properly on the wheel hub.
-- Check again whether the imbalance is less than 20 grams using the fine balancing machine.
The imbalance should be smaller than 20 grams, before changing balance weight.
-- Loosen the wheel bolts again, if necessary.
-- Rotate the wheel relative to the wheel hub once more by one or two wheel bolt holes.
-- Tighten the wheels according to the method described above.
Only if the imbalance is less than 20 grams should the imbalance be reduced by changing the balance weight.
-- Balance the wheels until the imbalance is below 5 grams.
-- Tighten the wheel bolts to the specified tightening specification if not already done.
Always tighten the wheel bolt to the tightening specification and using the torque wrench.
