20) Support transmission with a garage jack.
CAUTION:
Before moving engine away from transmission,
check to be sure no work has been overlooked.
Doing this is very important in order to facili-
tate re-installation and because transmission
lowers under its own weight.

17) Place the transmission with case left side fac-
ing downward and put ST1 on bearing cup.
18) Screw retainer assembly into left case from
the bottom with ST2. Fit ST3 on the transmission
main shaft. Shift 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.

20) Fit lock plate. Loosen the retainer on the lower
side by 1-1/2 notches of lock plate and turn in the
retainer on the 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.
21) Turn in the retainer on the upper side addition-
ally by 1 notch in order to apply preload on taper
roller bearing.
22) Tighten temporarily both the upper and lower
lock plates and mark both holder and lock plate for
later readjustment.
