ADJUSTMENT BEFORE REASSEMBLY



DIFFERENTIAL SIDE BEARING PRELOAD ADJUSTMENT


1.Set the differential assembly to the transmission case.

2.Push and fit the tapered roller bearing outer race by hand.

3.To fit the tapered roller bearing outer race, rotate the differential assembly by hand about 10 times with the special tool Preload socket (MB992038).

4.Put the transmission case on the surface table and use a height gauge to measure the dimension "a1," which is from the mating surface of the transmission case to the end surface of the tapered roller bearing outer race.

5.Put the straight edge on the mating surface of the transmission case and measure the dimension "b1" with a vernier caliper.
6.Select the shim whose dimension is the difference between "b1" and "a1."
7.Install the differential assembly to the transmission case. Tighten the transmission case bolts to the specified torque (29 ± 5 N·m).

8.Using special tool Preload socket (MB992038), measure the rotational starting torque of differential case. When it is not within the standard range, reselect the shim.
Standard value: 1.00 - 2.49 N·m

OUTPUT SHAFT No.2 BEARING PRELOAD ADJUSTMENT


1.Set the output shaft No.2 assembly and differential assembly to the transmission case.

2.Push and fit the tapered roller bearing outer race by hand.

3.To fit the tapered roller bearing outer race, rotate the output shaft No.2 assembly by hand about 10 times with the special tool Preload socket (MB992038).

4.Put the transmission case on the surface table and measure the dimension "a2," which is from the mating surface of the transmission case to the end surface of the bearing outer race, with a height gauge.

5.Put the straight edge on the mating surface of the transmission case and measure the dimension "b2" with a vernier caliper.
6.Select the shim whose dimension is the difference between "b2" and "a2."
7.Install the output shaft No.2 assembly and differential assembly to the transmission case. Tighten the transmission case bolts to the specified torque of 29 ± 5 N·m.

8.Using special tool Preload socket (MB992038), measure the rotational starting torque on the differential shaft. From this rotational starting torque, subtract the value measured in the adjustment of the bearing preload on the differential side. When this is not within the standard range, reselect the shim.
Standard value: 4.14 - 5.87 N·m
