SST 09316-60010 (09316-00010, 09316-00020)
11. INSTALL REAR BEARING

12. INSTALL OIL SLINGER AND NEW OIL SEAL
(a) Install the oil slinger facing as shown.
(b) Using SST, drive in a new oil seal as shown.
SST 09214-76011

Oil seal drive in depth: 1.0 mm (0.039 in.)

(c) Coat the lip of the oil seal with MP grease.

13. INSTALL COMPANION FLANGE

(a) Using SST, install the companion flange on the drive pinion.
SST 09557-22022 (09557-22050)
(b) Place the plate washer on the companion flange.

(c) Apply a light coat of gear oil on the threads of a new companion flange nut.
(d) Using SST to hold the flange, torque the nut.
SST 09330-00021
Torque: 2,000 kg.cm. (145 ft.lb., 196 N.m.)

14. CHECK DRIVE PINION PRELOAD
Using a torque meter, measure the preload of the backlash between the drive pinion and ring gear.

Preload (as starting):
New bearing: 10 - 16 kg.cm. (8.7 - 13.9 in.lb., 0.9 - 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 specification, replace the bearing spacer.
^ If the preload is less than specification, retighten the nut 130 kg.cm. (9 ft.lb., 13 N.m) a little 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 pinion nut to reduce the preload.

Maximum torque: 3,500 kg.cm. (253 ft.lb., 343 N.m.)

If everything is normal, coat the threads with gear oil, then repeat the above operation.

15. STAKE DRIVE PINION NUT

16. CONNECT FRONT PROPELLER SHAFT
(a) Align the matchmarks on the flanges and connect the flanges with four bolts, spring washers and nuts.
(b) Torque the bolts and nuts.
Torque: 750 kg.cm. (54 ft.lb., 74 N.m.)

17. CHECK DIFFERENTIAL OIL LEVEL
Fill with hypoil gear oil if necessary.

Oil type: Hypoid gear oil API GL-5

Recommended oil viscosity:
Above -18°C (0°F): SAE 90
Below -18°C (0°F): SAE BOW or 80W-90

Capacity: 2.8 liters (2.9 US qts, 2.4 Imp. qts)
