NOTICE:
Clearance is not allowed between the bearing
and transaxle housing.
6. ADJUST DIFFERENTIAL SIDE BEARING PRELOAD
(a) Install the differential assembly to the transaxle
case.
(b) Clean the matching surfaces of the transaxle case
and transaxle housing.
(c) Install the transaxle housing to the transaxle case
and tighten them with the 16 bolts
Torque: 22 N*m (224 kgf*cm, 16 ft.*lbf) for bolt A
29 N*m (296 kgf*cm, 21 ft.*lbf) for bolts
B and C
HINT:
Each bolt length is indicated below.
Bolt length:
50 mm (1.969 in.) for bolt A
50 m (1.969 in.) for bolt B
42 mm (1.654 in.) for bolt C
NOTICE:
Usually, bolt A is non-reusable bolt. In this case,
however, it can be used after cleaning it.
