(4) Install the assembly in the case, tap lightly with
a soft mallet if necessary. Place the deflector over
vent opening and install four pump body bolts, re-
move pilot studs and install the remaining bolts. Snug
the bolts down evenly, then tighten to 150 inch-pounds
torque. (The A-904-G and A-904-LA do not
use
a de-
flector
over the vent opening.)
Governor and Support
(1) Position the support and governor body as-
sembly on the output shaft. Align the assembly so the
governor valve shaft hole in the governor body aligns
with the hole in the output shaft, then slide the as-
sembly into place. Install the snap ring behind the
governor body (Fig.
54).
Tighten the body to support
bolts to 100 inch-pounds torque. Bend the ends of the
lock straps against the bolt heads.
(2) Place the governor valve on the valve shaft, in-
sert
the assembly into the body and through the gov-
ernor weights. Install the valve shaft retaining snap
ring.
Extension Housing-A-904-G
and A-904-LA
(1) Using a new gasket, carefully slide the exten-
sion housing into place. Install the retaining bolts and
washers, tighten bolts to 25 foot-pounds torque.
(2) Install the transmission output shaft flange. In-
stall washer with its three projections toward the
flange and the nut with its convoluted surface con-
tacting the washer. Hold the flange with Tool C-3281,
and tighten nut to 175 foot-pounds torque. Torque
reading must be taken as the nut passes over the
hump.
IMPORTANT: Inspect the drive train end play as
described on Page
79.
Correct if necessary.
Output Shaft Bearing and Extension
Housing-A-727-A
and
B
(1)
Install a snap ring in the innermost groove on
the output shaft. Install the bearing on the shaft with
its outer race ring groove toward the front (Fig.
53).
Press or tap the bearing tight against the front snap
ring, then install the rear snap ring.
(2) Unwind and slide the yoke seal stop ring into
place on the shaft. Install the seal with lips of seal to-
ward the rear.
(3) Place a new extension housing gasket on the
transmission case. Position the output shaft bearing
retaining snap ring in the extension housing. Spread
the snap ring as far as possible (Fig. 52), then care-
fully tap the extension housing into place.
Make sure
the snap ring
i s
fully seated in the bearing groove.
(4)
Install the gasket, plate and two screws on the
bottom of the extension housing mounting pad.
(5) Install and tighten extension housing bolts to 24
foot-pounds torque.
IMPORTANT: Measure the drive train end play as
described on Page
79.
Correct if necessary.
Valve Body Assembly and Accumulator
Piston
(1) Clean mating surfaces and inspect for burrs on
both the transmission case and the valve body steel
plate.
(2) Install the accumulator piston in the transmis-
sion case and place the piston spring on the accumu-
lator piston.
(3) Carefully position the valve body assembly in
the transmission case, install the retaining bolts and
tighten finger tight. With the neutral starting switch
installed, place the manual valve in the neutral posi-
tion. Shift the valve body if necessary to center the
neutral finger over the neutral switch plunger. Snug
the bolts down evenly, then tighten to 100 inch-
pounds torque.
(4) Connect the control cable adapter to the man-
ual lever and install the retaining E-clip.
(5) Install the seal, flat washer and throttle lever
on the throttle shaft. Tighten the clamp bolt.
(6)
Adjust the kickdown, and low-reverse bands, as
described on Page 59.
(7) Install the oil pan, using a new gasket. Tighten
the pan bolts to 150 inch-pounds torque.
