1. Install the transfer clutch assembly to the extension case with the transfer driven gear shims and thrust bearings removed.

2. Install the thrust bearing.

NOTE:

3. Using the ST, measure the height “A” from the ST end face to the thrust bearing catch surface of the transfer clutch assembly.

4. Using the ST, measure the height “B” from the transmission case mating surface to the end of ST.

5. Obtain the thickness of transfer driven gear shim using the following formula to select one to three transfer driven gear shims.

T (mm) = A − B − (0.05 — 0.25)

[T (in) = A − B − (0.002 — 0.01)]

T: Transfer driven gear shim thickness

A: Height from the ST end face to the transfer clutch assembly thrust bearing catch surface

B: Height from the mating surface of the transmission case to the end of the ST

0.05 — 0.25 mm (0.002 — 0.01 in): Clearance
