3.
Re-check the pattern and adjust as required to achieve the desired full contact, equal pattern.

When full contact is achieved, final torque the three locking bolts to 370 Nm.
Table 3.1 Gear Mesh Pattern
Engagement Pattern
Description
Remedy
Proper Tooth Contact
Pattern is visibly equal on both
top and bottom.
Full contact is achieved. Final torque the
three locking bolts to 370 Nm.
Top Too Tight
Pattern is visibly equal only
at the top.
Turn levelling screw 'B' clockwise to tip the
top of the pinion gear away from the ring gear
(Loosen and re-tighten locking bolt as
required).
Top Too Loose
Pattern is visibly equal only
at the bottom
Turn levelling screw 'C' clockwise to tip the
top of the pinion gear towards the ring gear
(Loosen and re-tighten locking bolt as
required).
Tipped Left
Pattern shows only top left
tooth and lower right tooth
Turn levelling screw 'A' clockwise to tip the
top of the pinion to the right (Loosen and re-
tighten locking bolt as required).
Tipped Right
Pattern shows only top right
tooth and lower left tooth
Turn levelling screw 'A' counter-clockwise to
tip the top of the pinion to the left. Again, it is
best to adjust by lifting up, so if the gear must
tip to the left, back off the levelling screw and
overcompensate to the left, making the final
adjustment to the right by lifting. (Loosen and
re-tighten locking bolt as required).
Over adjusting can cause the pinion to collide with the adapter plate. Take care to maintain adequate
spacing between the top of the pinion and the bottom of the adapter plate.
