Fit a centesimal comparator "DG1" with long stem into bar T26A;
when the bar rests on two size- blocks "GB" of 57 mm, reset the
comparator.
Preset the comparator to approx. 2 mm and reset.
Lay bar T26A on gauged nut T26C and take the size "A" at about
57 mm corresponding to the maximum diameter of arms centring.
Calculate size "B" which will be the first useful value for calculating
the size of the shims (14) that are to be inserted under the thrust
block of the internal bearing (9).
Check the nominal size (X) marked on the pinion and add or
subtract the indicated variation (Y) so as to obtain size "Z".
e.g.: Z= 118 + 0.1 = 118.1
Z= 118 ± 0.2 = 117.8
Calculate size "C" which represents the second value for
calculating the size of the shims "S" that are to be placed under
the thrust block of the internal bearing (9).
Calculate the difference between sizes "B" and "C" so as to obtain
the size "S" of the shim (14) that will go under the thrust block of the
internal bearing (9).
