Inspection

NOTE: To prevent damage to the transfer housing, always use soft jaws or equivalent materials between the transfer housing and a vise.

Transfer Gear Backlash Measurement





1. Set a dial indicator (A) on the companion flange (B).
2. Measure the transfer gear backlash.
STANDARD: 0.06 - 0.16 mm (0.02 - 0.06 inch)

Total Starting Torque Measurement
3. Rotate the companion flange several time to seat the tapered roller bearings.





4. Measure the starting torque at the companion flange (A) using a torque wrench (B).

Transfer Gear (Hypoid Gear) Tooth Contact Inspection





5. Remove the transfer cover (A) from the transfer housing (B), and remove the O-ring (C) from the transfer cover.
6. Remove the transfer drive gear/shaft assembly (D), 25 mm thrust shim (E), and tapered roller bearing (F).
7. Apply Prussian Blue to both sides of the transfer drive gear teeth lightly and evenly.
8. Install the tapered roller bearing, 25 mm thrust shim, and transfer drive gear/shaft assembly in the transfer housing.
9. Install the transfer cover, and tighten the bolts. Do not install the O-ring on the transfer cover.
10. Rotate the companion flange in both directions until the transfer gear rotates one full turn in both directions.





11. Remove the transfer cover and transfer drive gear/shaft assembly, and check the transfer drive gear tooth contact pattern. The pattern should be centered on the gear teeth as shown.
12. If the measurements are out of standard or the tooth pattern are not correct, disassemble the transfer assembly and repair it.
