Pinion – crown coupling
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 pinionʼs 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 crownʼs 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 crownʼs 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 pinionʼs 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
2
toothing is correct.
