Transfer Assembly
Reassembly
Note these items during reassembly:. 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 start-Ing rorque.
. Coat all parts with MTF during reassembly.. Replace the tapered roller bearing and the bearingouter 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 thrust shim.
Perform this procedure if the transler driven gear
shaft or the tapered roller bearing on the transferdriven gear shaft is replaced.
Preassemble the parts to check and adjust transfergear backlash and transfer gear tooth contact.
Disassemble the parts, then assemble the transferdriven gear shaft and its related parts.
4. Measure and adjust the staning torque of the trans-fer driven gear shaft tapered roller bearing.
5. Assemble the transfer shaft and jts related parts.
6. Measure and adjust the total starting torque.
35 mm Thrust Shim Seleqtion
1. Select the 35 mm thrust shim if the transfer drivengear shaft or the tapered roller bearing on the trans-fer driven gear shaft is replaced.
Calculate the thickness of the 35 mm thrust shimusing the formula below.

19. lf the transfer gear tooth contact is incorrect, adjust
the transfer gear tooth contact with a 35 mm or 25
mm thrust shim.
NOTE:
. To select a 35 mm thrust shim, refer to page '13-
. Do not use more than one 35 mm shim to adjust
the transfer gear tooth contact.
. To select the 25 mm thrust shim, refer to page
13-55.
a Do not use more than one 25 mm shim 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 drive
gear. Because this movement causes the transfer
gear backlash to change, move the transfer drive
gear away from the transfer driven gear shaft to
adjust the transfer gear backlash as iollows;
. Increase the thickness of the 25 mm thrust
shim.
. Reduce the thickness of the 68 mm thrust
shim bv the amount of increased thickness of
the 25 mm thrust shim.
Heol Contact
Use a thinner 35 mm thrust shim to move the
transfer driven gear shaft away from the transfer
drive gear. Because this 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
sh im.
a Increase the thickness of the 68 mm thrust
shim by the amount of reduced thickness of
the 25 mm thrust shim.
Flank Contact
Use a thinner thrust shim to move the transfer
drive gear toward the transfer driven gear shaft.
Flank contact must be adtusted within the limits
of the transfer gear backlash. lf the backlash
exceeds the limits, adjust as described under
Heel Contact.
Face Contsct
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 transjer gear backlash. lf the back-
lash exceeds the limits, adjust as described
under Toe Contact.
