Assembly of Differential Case
DIFFERENTIAL CASE ASSEMBLY
1. ASSEMBLE DIFFERENTIAL CASE
a. Install the correct thrust washers and side gears. Referring to the images, select thrust washers which will ensure that 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.)
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 gear toward the 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 case and hole in the pinion shaft.
f. Stake the differential case.
2. 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 remove the ring gear from 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. Install the 6 set bolts. Tighten each set bolt uniformly, a little at a time in succession. Torque the bolts.
Torque: 124 N.m (1,260 kgf.cm, 91 ft.lbf)
3. INSTALL SIDE BEARING
a. Install the speedometer drive gear to the RH side.
b. Using SST and a press, install new side bearings to the both sides of the case.
SST 09350-32014 (09351-32090,09351-32120)
4. INSPECT DIFFERENTIAL SIDE BEARING PRELOAD
a. Install the differential case assembly to the transaxle case.
b. Install the transmission case.
c. Install and torque the case bolts.
Torque: 29 N.m (300 kgf.cm, 22 ft.lbf)
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 0.5 - 1.0 N.m (5 - 10 kgf.cm, 4.3 - 8.7 in.lbf)
If the preload is not within the specification, remove the transmission case side outer race of the side bearing with SST.
Select another shim.
HINT: The preload will change by about 0.3 - 0.4 N.m (3 - 4 kgf.cm, 2.6 - 3.5 in.lbf) with each 0.05 mm change in shim thickness.
