Reassembly:
Carefully check the components before reassembly.
Follow the disassembly instructions in reverse order,
remembering the following:
• Fit the crown “R”, checking that the selection values
for coupling the pinion “Q” and the crown “R” match;
Refit the cover, making sure that the part with the writing
(lower) is facing the oil drain plug.
To check the pinion and crown coupling, grease the pinion
toothing, drive side, with red lead grease.
Using an armed extractor “A” and a suitable shim “B” keep
the hub-crown unit slightly forced towards the cover; turn
the pinion “C” by hand in the sense-of-travel, using the
tool to keep the crown still.
Remove the extractor, disassemble the cover and check
the contact area on the pinion toothing.

ONTACT IMPRESSION CHECK
• If the contat is correct, the pinion toothing impression
will be as illustrated in figure “1” (the pinion is viewed
from the drive shaft side)
• If the contact is like illustration “2”, the crown is too
near the pinion’s rotating axis: loosen the crown by
increasing the thickness of the shim “P”, previous page,
between the box and the cover;
• If the contact is like illustration “3”, the pinion is too
near to the crown’s rotation axis: move the pinion farther
by reducing the thickness of the shim between the
bearing and the pinion;
• If the contact is like illustration “4”, the pinion is too far
from the crown’s rotation axis: bring the pinion closer
by increasing the thickness of the shim, between
bearing and pinion;
• If the contact is like illustration “5”, the crown is too far
from the pinion’s rotation axis: bring the crown closer
by reducing the thickness of the spacer “P”, previous
page, between the housing and the cover;
• The backlash must be within 0.10÷0.15 mm, if the
coupling between the pinion toothing and the crown
toothing is correct.
