ZF16S221 output shaft steel pad

This is the precision hardened steel thrust/adjustment shim for the output/mainshaft of ZF 16S221 16-speed heavy-duty ECOSPLIT4 manual truck transmissions. It is installed on the output shaft assembly, used to set axial clearance, adjust preload, absorb axial thrust, reduce vibration and control bearing and gear runout. It ensures correct shaft positioning, prevents axial movement, abnormal noise, bearing damage and premature gear wear, widely used on European heavy long-haul tractors fitted with ZF 16S221 16-speed gearboxes. It includes various thickness specifications for differential preload and end-play adjustment during overhaul.
