TRANSFER CASE (TOD) 5D2-51
25. Install the pin on the tang end of the helical cam into thehole in the front case. Position the torsion spring tangs so that they are pointing toward the top side of the transfer case and just touching the high-low shift fork. CAUTIONDo not bend the helical cam during installation to the front case because of possible damage to the pin at the tangend of the motor shaft.
26. Install the shift rail through the high-low shift fork and make sure that the reverse gear shift rail is seated in the frontcase bore.
27. Install upper and lower speed sensors into the cover. Feed the coil wire through the upper speed sensor wire shield.
2 8. Install upper tone wheel, speedometer gear and rear output seal. Use Output Shaft Seal Replacer and Driver orequivalent to install seal.
29. Coat the mating surface of the front case with a bead of Black Non-Acid Cure Silicone Rubber or equivalent.
30. The following procedure must be followed prior to installing the rear case onto the front case half:
a. Align the output shaft with the rear case output shaft bore.
b. Align the helical cam with the rear case motor bore. If difficulty is encountered with seating the rear case, tap
the rear output shaft with a sharp blow using a rubber
mallet in a direction away from the triangular shaft whilepushing down on the rear case.
Tightening Torque 25 - 37 Nm
31. Install the bolts retaining the case halves and tighten.

32. Install shift shaft oil seal if it is not installed.
33. Using pliers equipped with soft jaws, rotate the triangularshaft so it is aligned with the triangular slot in the transfer
case shift motor. If triangular shaft will not rotate, rotate the rear output shaft.
34. Slightly loosen the two nuts that attach the slotted support bracket to the end of the motor house.
35. Apply Black Non-Acid Cure Silicone Rubber or equivalent to motor housing base and install on transfer case.
36. Install the transfer case shift motor and three bolts along with speed sensor wire harness bracket and tighten. NoticeThe wire harness must be routed as shown to provide clearance and to prevent the wire harness from grounding
the damper.
37. Holding the slotted support bracket tight against the motor housing end, secure the bracket to the transfer case,
tightening the bolt with lockwasher to 8-11 Nm (72-96 lb-in).
38. Retighten the two nuts that attach the slotted support bracket to the end of the motor.
39. Install the clutch coil wire terminal and sensor wires.
