DIFFERENTIAL CARRIER ASSEMBLY - CONTINUED

Adjust Input Bearing End Play.

NOTE

If original input shaft forward bearing was installed with original shim pack (Assemble Input Shaft and

Bearings, k, (5), tighten yoke nut enough to eliminate any play between the yoke and bearings; then proceed

to step (5).

(1)

With the forward input bearing in place and the bearing cover (34) assembled finger-tight on the helical

gear cover (17) with no shim pack, measure the gap between the bearing cover and helical gear cover

using a feeler gage.

(2)

Add approximately 0.005 inch (0.127 mm) to measurement figure of gap. Add this amount of shims under

the bearing cover (34).

NOTE

Use a minimum of three shims under bearing cover with the thinnest shims on outer sides.

(3)

Remove the input yoke (15) if assembled and bearing cover (34) and install the initial amount of shims.

Reassemble the cover, washers (36) and capscrews (32). Torque capscrews to 35-50 lb-ft (47-68 Nm).

(4)

Assemble the input yoke (15) and nut (16) over the input shaft (33). Tighten the yoke nut enough to elimi-

nate any play between the yoke and the bearing.

(5)

Check the bearing end play using a dial indicator mounted against the nose of the input shaft (33). Use a

dial indicator with a magnetic base or c clamp arrangement mounted on the helical gear cover (17).

(6)

Holding the input yoke (15), push in the input bearing while turning the yoke side to side to seat the bear-

ing. Set the indicator to zero.

(7)

Next, pull the yoke (15) outward, again turning it side to side and take note of reading on the dial indicator.

(8)

Final end play must be between 0.003-0.007 inch (0.076-0.178 mm). If not, adjust by either adding or

removing shims from under the bearing cover (28) and repeat above procedures.
