22 SECTION 27 - REAR AXLE
The procedure to determine value X occurs in the
following manner:
Z install the largest shim (for instance 2.286 mm);
Z position the gear assy;
Z screw and tighten screw at 554÷626 Nm;
Z by means of a dial gauge, find out the axle back-
lash (for instance 0.562 mm);
Z subtract endfloat from shim already fitted, for ex-
ample 2.286 - 0.562 mm = 1.724 mm.
The “Resultant value” is obtained.
Z starting from the “Resultant value”, refer to the ta-
ble for the correct shim to replace the 2.286 one.
IMPORTANT: increasing shim thickness will reduce
preload. Decreasing shim thickness will increase
preload.
Z fit selected shim and re-tighten retained screw to
correct torque and allow lock plate to locate.
