Adjustment of Differential Case

NOTICE: This article was copied from the AT section (A140E) as directed by the OE service manual. Images may differ from the S51 transaxle, but the procedures are correct.


INSTALL AND ADJUSTMENT OF DRIVE PINION ASSEMBLY





1. INSTALL NEW 0-RING ONTO BEARING CAGE





2. INSTALL DRIVE PINION SHAFT INTO CASE
Slightly tap the cage into the case until the groove with the bore can be seen.

HINT: Drive in the bearing cage until the surface of the bearing cage passes through the groove with the bore.

3. INSTALL SNAP RING INTO CASE





(a) Using SST, install the snap ring into the groove.
SST 09350-32014 (09351-32050)





(b) Slightly tap the drive pinion to fit the snap ring into the groove.





4. INSTALL OIL SLINGER
Install the oil slinger, facing the lip outward.





5. INSTALL OUTER RACE
Using SST, drive the outer race into the case.
SST 09350-32014 (09351-32100, 09351-32140)





6. INSTALL NEW SPACER
- Always use new spacer.
- Install the spacer with the small end first.

7. INSTALL COUNTER DRIVEN GEAR ONTO SHAFT





(a) Place a bar at the drive pinion side and position the outer end of the bar against a vise or such.





(b) Using SST, drive in gear onto the shaft until the nut can be installed on the threads of the shaft.
SST 09350-32014 (09351-32140)

NOTICE: Be careful not to cause an impact to the transmission case.

8. ADJUST DRIVE PINION PRELOAD
(a) Coat the threads and surface of the nut with MP grease.





(b) Using SST to hold the gear, tighten the nut.
SST 09330-00021, 09350-32014 (09351-32031)

Torque: 1,750 kg-cm (127 ft-lb, 172 N-m)

(c) Turn the gear counterclockwise and clockwise several times.





(d) Using a torque meter, measure the preload of the drive pinion.

Preload (at starting):
New bearing: 10 - 16 kg-cm (8.7 - 13.9 in-lb, 1.0 - 1.6 N-m)
Reused bearing 5 - 8 kg-cm (4.3 - 6.9 in.-lb, 0.5 - 0.8 N-m)

^ If the preload is greater than specified, replace the bearing spacer.
^ If the preload is less than specified, retighten the nut 130 kg-cm (9 ft-lb, 13 N-m) at a time until the specified preload is reached.

If the maximum torque is exceeded while retightening the nut, replace the bearing spacer and repeat the preload procedure. Do not back off the nut to reduce the preload.

Maximum torque: 2,950 kg-cm (213 ft-lb, 289 N-m)

(e) If the preload is adjusted within specification, make a note of it.
