Power Divider
Install Power Divider on Differential Carrier
(with carrier removed from axle housing)
The following instructions pertain to installation of power di-
vider on differential carrier with carrier removed from axle
housing.
1. If output shaft side gear bearing cup was removed,
press bearing cup in carrier. Use a press and appro-
priate sleeve or use a brass drift and a mallet. Tap
bearing cup into its bore making certain cup is evenly
and firmly seated.
2. Lubricate o-rings, then install output shaft assembly
in carrier.
3. Insert axial spring and thrust button in the end of the
output shaft.
Note: Early model axles may not be equipped with axial spring
and thrust button. If your axle was not equipped with
these parts, go to step 4.
4. Install inter-axle differential assembly on output shaft
side gear (with nuts facing away from output shaft
side gear).
5. Apply silicone gasket compound on carrier mating
surface.
Note: Gasket compound will set in 20 minutes. Install power
divider before compound sets or reapply.
6. Attach chain hoist to input yoke and install power di-
vider assembly. During installation, rotate input shaft
to engage input shaft splines with inter-axle differen-
tial. After installation, rotate input shaft again. Output
shaft should turn when input shaft is rotated if as-
sembly is correct.
