Measure and Adjust Input Shaft End-Play
Note: After power divider overhaul and installation on carrier,
check and adjust input shaft end-play.
The correct end-play when new parts are used in overhaul is
0.003" to 0.007", with reused parts the maximum is 0.014".
1. Remove input shaft nut. Remove input bearing cover
cap screws. Remove bearing cover (and shim pack if
installed).
2. Reinstall bearing cover without shims. Hold in posi-
tion with hand pressure and measure clearance
between power divider cover and bearing cover,
using a feeler gauge.
3. The bearing cover clearance measured in Step 2 plus
0.005" will equal shim pack thickness required for
desired end-play (rebuild with new parts). Add
0.015" to shim pack for rebuild with used parts.
4. Install shim pack and bearing cover. Install cap
screws. Torque screws to 114–140 lb-ft. (155–190
N•m). Make sure shims are flat with no kinks or
bends.
5. Install yoke using installation tool and nut. Tighten
nut snugly. Tap end of input shaft lightly to seat bear-
ings.
6. Check input shaft end-play with dial indicator posi-
tioned at yoke end of input shaft. Move input shaft
axially and measure end-play. If end-play is correct,
seal shim pack with Dana approved RTV compound
to prevent lube leakage. Then torque input shaft nut.
7. If end-play is incorrect, change shim pack size as fol-
lows:
Add shims to increase end-play.
Disassemble shim to decreased end-play.
