11) Screw the retainer assembly into left case from
the bottom with ST2. Fit the ST3 on transmission
main shaft. Shift the gear into 4th or 5th and turn
the shaft several times. Screw in the retainer while
turning ST3 until a slight resistance is felt on ST2.
This is the contact point of hypoid gear and drive
pinion shaft. Repeat the above sequence several
times to ensure the contact point.

12) Remove the weight and screw in the retainer
without O-ring on upper side and stop at the point
where slight resistance is felt.
NOTE:
At this point, the backlash between hypoid gear
and drive pinion shaft is zero.

13) Fit the lock plate. Loosen the retainer on the
lower side by 1-1/2 notches of lock plate and turn in
the retainer on upper side by the same amount in
order to obtain the backlash.
NOTE:
The notch on the lock plate moves by 1/2 notch if
the plate is turned upside down.
14) Turn in the retainer on the upper side addition-
ally by 1 notch in order to apply preload on taper
roller bearing.
15) Tighten temporarily both the upper and lower
lock plates and mark both holder and lock plate for
later readjustment.
