4. Measure the height W between transfer case and taper roller bearing on the transfer driven gear.
5. Measure the depth X.
NOTE: Measure with bearing cone and thrust washer removed.
6. Calculate the space t using the following equation: t = X - W + 0.2 to 0.3 mm (0.008 to 0.012 inch)
7. Select the nearest washer in the following table:
Standard clearance between thrust washer and taper roller bearing: 0.2 - 0.3mm (0.008 - 0.012 inch)
NOTE: Be sure to keep the clearance within specifications.
8. Fit the thrust washers on transfer drive shaft.
9. Install the bearing cone into extension case.
10. Measure the depth S between transfer case and center differential.
ST 398643600 GAUGE
11. Measure the depth T between extension case and transfer drive gear.
ST 398643600 GAUGE
12. Calculate the space U using the following equation: U = S + T - 30 mm (1.18 inch) [Thickness of ST]
13. Select the suitable washer in the following table:
Standard clearance: 0.15-0.35 mm (0.0059-0.0138 inch)
14. Fit the thrust washer on center differential.
15. Apply proper amount of liquid gasket to the transfer case mating surface.
