Honda Fit: A/T Differential Carrier Bearing Preload Inspection (A/T)

Special Tools Required

• Driver Handle, 15 x 135L 07749-0010000
• Bearing Driver Attachment, 72 x 75 mm 07746-0010600
• Preload Inspection Tool 07HAJ-PK40201

NOTE: If the transmission housing, torque converter housing, differential carrier, tapered roller bearing, bearing outer race, or thrust shim were replaced, the bearing preload must be adjusted.

1. Remove the bearing outer race (A), the 76.2 mm spacer (B), and the 76 mm thrust shim (C) from the transmission housing (D) by heating the housing to about 212 °F (100 °C) with a heat gun (E). Do not heat the housing more than 212 °F (100 °C).

   

   NOTE: Let the transmission housing cool to room temperature before adjusting the bearing preload.

2. Replace the tapered roller bearing when the outer race is to be replaced.

3. Do not use a shim on the torque converter housing side.

4. Install the 76 mm thrust shim (A) in the transmission housing (B). If you replace the 76 mm thrust shim with a new one, use the same thickness shim as the old one.

1. Install the 76.2 mm spacer (C) and the bearing outer race (D) in the transmission housing.

6. Drive the outer race securely in the housing using the driver handle and the bearing driver attachment (72 x 75 mm), so there is no clearance between the outer race, the spacer, the shim, and the housing.

7. Install the differential assembly (A) in the torque converter housing (B), and install the gasket (C) and the three dowel pins (D) on the housing.

8. Install the transmission housing (E), and install the transmission housing mounting bolts. Tighten the 19 bolts   to 44 N·m (4.5 kgf·m, 33 lbf·ft) in at least two steps in a crisscross pattern.

9. Rotate the differential assembly in both directions to seat the bearings.

10. Measure the starting torque of the differential assembly with the special tool, a torque wrench (A), and a socket (B). Measure the staring torque at normal room temperature in both directions.

    Standard
    New Bearing:
    2.7-3.9 N·m (28-40 kgf·cm, 24-35 lbf·in)
    Reused Bearing:
    2.5-3.6 N·m (25-37 kgf·cm, 22-32 lbf·in)



11. If the starting torque is out of the standard, remove the thrust shim and measure its thickness.




12. Select a new thrust shim. To increase the starting torque, increase thickness of the thrust shim. To decrease the starting torque, decrease the thickness of the thrust shim.

    Changing the shim to the next size will increase or decrease the starting torque about 0.5-0.6 N·m (5-6 kgf·cm, 5-5 lbf·in)
