Inspection
Inspect Primary Gearing
Before reusing a primary gear set, inspect teeth for signs of ex-
cessive wear. Check tooth contact pattern for evidence of in-
correct adjustment.
Check Input Shaft End-play (Forward Axle)
Note: Before disassembling the power divider, measure and
record input shaft end-play.
See illustration for steps 1-3.
1.
Position dial indicator at yoke end of input shaft.
2.
Push in on input shaft and zero the dial indicator.
3.
Using a pry bar, move input shaft axially and mea-
sure/record end-play.
Adjustment
Correct end-play for a new assembly is .003" to .007". The
maximum end-play for a used assembly is no more than .014".
If end-play is incorrect, determine shim pack changes as fol-
lows:
Check Output Shaft End-play
(Forward Axle)
See illustration for steps 1-3.
1.
Position dial indicator at yoke end of output shaft.
2.
Push in on output shaft and zero the dial indicator.
3.
Using a pry bar, move input shaft axially and mea-
sure/record end-play.
Adjustment
Correct end-play for a new assembly is .001" to .005". The
maximum end-play for a used assembly is no more than .005".
If end-play is incorrect, contact Dana.
