6. Make certain dowel pins are installed in carrier, then
install power divider assembly.
TIP: During installation, rotate input shaft to engage
input shaft splines with inter-axle differential. After
assembly output shaft should turn when input shaft
is rotated, and output shaft should turn independent-
ly from the input shaft.
TIP: The use of two guide pins in the carrier mating
surface will help align the PDU cover and aid in instal-
lation. Guide pins may be made from 9/16"-12 UNC
bolts approximately four inches long with the heads
removed.

socket head capscrew to 115-125 lbs. ft. (155-169
N•m).

vider assembled to differential carrier, check end play

play is within specifications, complete assembly pro-
cedures as follows:
