Transfer Assembly
Reassembly
NOTE:
. While reassembling the transfer assembly:. Check and adjust the transfer gear tooth contact.. Measure and adjust the transfer gear backlash.. Check and adjust the tapered roller bearing stan-
ing torque.
. Coat all pans with ATF during reassembly.. Replace the tapered roller bearing and the bearing
outer race as a set if either part is replaced.. Replace the transfer drive gear and the transfer dri-ven gear shaft as a set if either part is replaced.
Outline of Assembly
1.Select the 35 mm thrusi shim.
Psrtorm this procedute if the transter driven g€ar
shaft or the tapered roller bearing on the transfer
driven gear shaft is replaced.
Prea$emble the parts to check and adiust transtelgear backlash and transfer gear tooth contact.
Disassemble the parts, then assemble the translerdriven gsar shaft and its related pans.

4. Measure and adjust the starting torque oI the
transfer driven gear shaft tapered roller bearing.
5. Assemble the transfer shaft and its related parts.
6. Measure and adiust the total starting torque.
35 mm Thrust Shim Selection

fer driven gear shaft is replaced.
Calculate the thickness of the 35 mm thrust shimusing the formula below.

the transfer gear rotates one full turn in both direc-
tions.
Check the transfer gear tooth contact pattern.

19. lf the transfer gear tooth contact is incorrect, adjust
the transfer gear tooth contact with a 35 mm or 25
mm th rust shim.
NOTE:
. To select a 35 mm thrust shim, refer to page 14,240.
. Do not use more than two 35 mm shims to
adjust the transfer gear tooth contact.. To select the 25 mm thrust shim, refer to page
14-243.
. Do not use more than two 25 mm shims to
adjust the transfer gear tooth contact.
Toe Contact
Use a thicker 35 mm thrust shim to move the
transfer driven gear shaft toward the transfer drivegear. Because this movement causes the transfergear backlash to change, move the transfer drivegear away from the transfer driven gear shaft to
adjust the transfer gear backlash as follows:. Increase the thickness of the 25 mm thrust
shrm.
. Reduce the thickness of the 68 mm thrust
shim by the amount of increased thickness of
the 25 mm thrust shim.
Heel Contact
Use a thinner 35 mm thrust shim to move the
transfer driven gear shaft away from the transfer
drive gear. Because thjs movement causes the
transfer gear backlash to change, move the trans-
fer drive gear toward the transfer driven gear shaft
to adjust the transfer gear backlash as follows:. Reduce the thickness of the 25 mm thrust
shim.
. Increase the thickness of the 68 mm thrust
shim by the amount of reduced thickness ofthe 25 mm thrust shim.
Flank Contaqt
Use a thinner thrust shim to move the transfer
drive gear toward the transfer driven gear shaft.Flank contact must be adjusted within the limits
of the transfer gear backlash. lf the backlash
exceeds the limits, adjust as described underHeel Contact.
Face Contaqt
Use a thicker thrust shim to move the transfer
drive gear away from the transfer driven gear
shaft. Face contact must be adjusted within the
limits of the transfer gear backlash. lf the back-
lash exceeds the limits, adjust as described
under Toe Contact.
