TRANSMISSION REPAIR (Continued)
(p) Install the proper pinion guide pins, larger
diameters first, into the pinion pin bores. Push
the guide pins through the carrier until the
loading pins drop out.
(q) Position the carrier assembly on the press
fixture, using the proper pin remover and
installed adapter (if required).
NOTE
Pin
installers
are
shaped
to
avoid
interference with bosses on the carrier
assemblies. They must be installed in the
ram so the cutaway portion of the installer
will clear the bosses when the pinion pin
(286) is pressed in.
(r)
Select the proper pin installer, and install it into
the press fixture ram.
Do not put pressure on the carrier. Distortion of
the carrier will damage it.
(s)
Place a pinion pin (286) on the pilot end of the
pin guide located below the press fixture am.
Press the pinion pin into the carrier until the
installer contacts the carrier.
(t) Install the remaining pinion pins (286).
(u) Remove the carrier assembly from the press
fixture. Install swaging tool holder into the
opening of the press fixture bed. Install a swaging
tool into the holder. Install another swaging tool
into the press fixture ram. Lubricate both ends of
the pinion pins with oil-soluble grease (Appendix
D, Item 21).
(v)
Position the carrier assembly, rear end upward
(except the center carrier) on the press fixture.
Use the proper support block to level the carrier
while the lower swaging tool is supporting the
lower end of the one pinion pin.
NOTE
Swaging pressure varies with the size of the pinion
pins (approximately two tons for front carriers; three
tons for center and rear carriers). While applying
pressure, rotate the pinions and feel for reduction
of end play. The pinions must rotate freely and have
0.008-0.031 inch (0.20-0.79 mm) minimum end play
after swaging the pins.
