NOTE. If the ring nuts (1) are removed, spread them with Loctite
242.
Tighten ring nuts on the crown side until clearance between pinion
and crown is zero, then lock the crown; go back 1/4v1/2 turn.
Pre-set the bearings by means of the ring nut situated on the
opposite side of the crown, so as to increase pinion torque up to
140v210 Ncm.
CAUTION! If bearings are not new, check the static torque; if
bearings are new, check the continuous torque.
Introduce a comparator with rotary key "A" through the top plug
hole (10). Position the comparator on the centre of one of the teeth
of the crown (12), pre-set it to 1mm and reset it.
Manually move the crown (12) in both directions in order to check
the existing backlash between the pinion and the crown.
Adjust the backlash between the pinion and the crown by
unloosing one of the ring nuts (1) and tightening the opposite to
compensate.
Normal backlash: see table.
