– Measure "C" with a set of shims.

– Fit shims of a thickness corresponding to the measured play. Zero play and preload with a tolerance of 0 ± 0,05 mm. If possible, adjust towards the maximum end of this tolerance. For example, if the play measured is 0,82 mm 0,82 – 0,05 = 0,77 0,82 + 0,05 = 0,87 In this example, the thickness of the shims to be installed should be between 0,77 and 0,87 mm (and as close to 0,87 mm as possible).
