Adjust the axial play "E" by means of shim as per the calculation example.
Example calculation:

Dimension "a" 49, 9 mm

Dimension "b" 49, 0 mm

Difference 0, 9 mm

Axial play "E" -0, 4 MM

Shim 0, 5 mm
Install the corresponding shim.
Shims are available in thicknesses of 0.2 to 0.5 mm. The graduation is 0.1 mm.
