Reassembly

1. ASSEMBLE DIFFERENTIAL CASE

(a) Install the correct thrust washers and side gears.

Refer to the table below, select thrust washers which wilf ensure thai the backlash is within the specification. Try to select washers of the same size for both sides. Standard backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 in.)

Thickness mm (in.)

(b) Install the thrust washers and side gears in the differential case.

(c) install the pinion shaft.

(b) Install the thrust washers and side gears in the differential case.

(c) install the pinion shaft.

(d) Using a dial indicator, check the side gear backlash. Measure the side gear backlash while holding one pinion toward the differential case.

Standard backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 in.) If the backlash is not within the specification, install a thrust washer of different thickness.

(e) Using a pin punch and hammer, drive in the straight pin through the differential case and hole in the pinion shaft.

(f) Using a chisel and hammer, caulk the pin holes around the circumference of the differential case.

2. Ring gear side:

INSTALL TAPERED ROLLER BEARING

Using SST and a press, install the tapered roller bearing.

SST 09350-32014 (09351-32120, 09351-32140) NOTICE:

When replacing the tapered roller bearing outer race, replace the tapered roller bearing along with it.

HINT:

Set SST to the bearing inner race securely.

3. Vehicle speed sensor drive gear side: INSTALL TAPERED ROLLER BEARING

(a) Place the vehicle speed sensor drive gear in position to stop it turning, and install the vehicle speed sensor drive gear. NOTICE:

Be sure to install the vehicle speed sensor drive gear in the correct direction, as shown In the Illustration.

(b) Using SST and a press, install a new side bearing. SST 09318-60011 (09316-00011), 09350-32014 (09351-32120)

NOTICE:

When replacing the tapered roller bearing outer race, replace the tapered roller bearing along with it.

HINT:

Set SST to the bearing inner race securely.

4. INSTALL RING GEAR ON DIFFERENTIAL CASE

(a) Clean the contact surface of the differential case.

(b) Heat the ring gear in boiling water.

(c) Carefully take the ring gear out of the water.

(d) After the moisture on the ring gear has completely evaporated, quickly install the ring gear to the differential case.

HINT:

Align the matchmarks on the differential case and contact the ring gear.

(e) Temporarily install the 8 set bolts. CAUTION:

The ring gear set bolts should not be tightened until the ring gear has cooled sufficiently.

(f) After the ring gear has cooled sufficiently, torque the ring gear set bolts uniformly at a time.

5. INSPECT DIFFERENTIAL TAPERED ROLLER BEARING PRELOAD NOTICE:

Perform this only when replacing the tapered roller bearing and outer race of the differential case.

(a) install the differential case assembly to the transaxle case.

(b) Install the transmission case to the transaxle case with the 16 bolts.

(c) Using SST and a torque wrench, turn the differentia! case assembly right and left 2 or 3 times to allow the bearings to settle.

(d) Using SST and a torque wrench, measure the preload. SST 09564-32011

Preload (at starting): New bearing

0.8 - 1.6 N-m (8 - 16 kgf-cm, 6.9 - 13.9 in.lbf) Reused bearing

If the preload is not within the specification, remove the transmission case side outer race of the tapered roller bearing with SST (See page MX-46). Select an appropriate shim. HINT:

The preload will change by about 0.3 ~ 0.4 N-m (3-4 Kgf-cm, 2.6-3.5 in.-lbf) corresponding to a change of 0.05 mm (0.0020 in.) in shim thickness.
