Transfer Assembly Inspection

Transfer Assembly Inspection

Transfer Gear Backlash Measurement on Vehicle

1. Raise the vehicle on a lift, and make sure it is supported securely.

2. Move the shift lever to N.

3. Make a reference mark (A) across the No. 1 propeller shaft (B) and the transfer companion flange (C).






4. Separate the No.1 propeller shaft from the transfer companion flange.

5. Set a dial indicator (A) on the transfer companion flange (B); position the dial indicator tip (C) on the direct extension of the bolt hole center (D).





6. Measure the transfer gear backlash.





- If the backlash is out of the standard, replace the transfer assembly.

- If the backlash is within the standard, and the inspection is complete, go to step 7.

7. Install the No. 1 propeller shaft (A) to the transfer companion flange (B) by aligning the reference mark (C).






Total Starting Torque Measurement

NOTE: To prevent damaging the transfer housing, always use wood blocks or equivalent materials between the transfer housing and the bench vise.

1. Remove the transfer assembly Transfer Assembly Removal.

2. Secure the transfer housing (A) in a bench vise (B) with soft jaws.





3. Rotate the transfer companion flange several times to seat the tapered roller bearings.

4. Measure the total starting torque at the companion flange (C) using a torque wrench (D) and a socket (E).





- If the total starting torque is out of the standard, replace the transfer assembly.

- If the total starting torque is within the standard, go to step 5.

5. Install the transfer assembly Transfer Assembly Installation.

Fluid Leak Check

1. Check for fluid leaks between the mating surfaces of the transfer assembly and the transmission.

- If there is a leak, remove the transfer cover, then replace the transfer cover oil seal and the O-ring Transfer Cover Oil Seal Replacement.

2. Check for fluid leaks between the transfer companion flange and the transfer oil seal.

- If there is a leak, replace the transfer oil seal and O-ring Transfer Oil Seal Replacement. Do not replace the oil seal with the transfer assembly on the transmission.
