Transfer Assembly Inspection
- Set a dial indicator (A) on the companion flange (B).
- Measure the transfer gear backlash.
Standard: 0.06-0.16 mm (0.02-0.06 in.)
- Secure the transfer housing (A) in a bench vise (B) with soft jaws. To prevent damage to the transfer housing, always use soft jaws or equivalent materials between the transfer housing and the vise.
- Rotate the companion flange several times to seat the tapered roller bearings.
- Measure the starting torque at the companion flange (C) using a torque wrench (D).
Standard: 2.16-3.57 N.m (22.0-36.4 kgf.cm, 19.1-31.6 lbf.in.)
- Remove the transfer assembly from the vise.
- Remove the transfer holder (A) from the transfer housing (B), then remove the O-ring (C) from the transfer holder.
- Apply Prussian Blue to both sides of the transfer drive gear teeth lightly and evenly.
- Install the transfer holder, and tighten the bolts. Do not install the O-ring on the transfer holder.
- Rotate the companion flange in both directions until the transfer gears rotate one full turn in both directions.
- Remove the transfer holder, and check the transfer drive gear tooth contact pattern. The pattern should be centered on the gear teeth as shown.
- If the measurements are out of standard of the tooth contact pattern are incorrect, disassemble the transfer assembly and repair it.
