151. Now
that we have an acceptable pattern we can start our final
assembly. |
|
152. We will remove our
carrier bearing saddle bolts and apply Loctite and reinstall
them. |
|
|
|
153. Then torque the differential
bearing cap bolts to 77 ft lbs. |
|
154. We will now remove
our pinion flange bolt. |
|
|
|
155. Using our puller we
will remove the pinion flange. |
|
156. Here we have removed
the pinion flange again. |
|
|
|
157. We once again remove
our oil slinger washer. |
|
158. We will remove the
forward pinion bearing again also. |
|
|
|
159. Now we install our
new crush sleeve. |
|
160. Reinstall the forward
pinion bearing. |
|
|
|
161. Reinstall the oil slinger
washer. |
|
162. Now lightly press them
in. |
|
|
|
163. Next we will install
our new pinion oil seal. We will coat the outside edge
with RTV prior to installing. |
|
164. Now we place the seal
in place and gently drive the seal into place by tapping
around the edge with a soft block punch. Careful not to
damage the seal. |
|
|
|
165. Then when fully seated
wipe the excess RTV from the seals edge. |
|
166. We can now reinstall
our pinion flange. |
|
|
|
167. Then we will install
a new pinion nut. |
|
168. This time we only tighten
the pinion nut snug. We will not be concerned about removing
the front to back movement in the bearings this time.
Just get it tight for now. |
|
|
|
The
following two steps (Photos 169 and 170) are important
when using the new crush sleeve. We will use our wrecking
bar setup to hold the pinion from turning. Once again
we will turn the pinion nut in 1/8th turns and re-check
our running torque with our torque wrench; spinning thru
one revolution between checks again. But the difference
this time is we will need much more force to get our running
torque correct. We will need to crush the new crush sleeve
this time and we must be very attentive to our torque.
And NEVER back the pinion nut off. If you do, the crush
sleeve will need to be replaced.
So go slow and re-check your torque often as you go. It
will sneak up and rise quickly once the sleeve starts
to crush. The torque required can be in excess of 200
ft lbs to do this. But remember we are not concerned with
the torque we put on the nut. We want to obtain our running
torque. |
|
|
|
169. Turning the pinion
nut in 1/8th turns and re-checking our running torque
with our torque wrench. |
|
170. Going slow and re-checking
the torque often as we go. |
|
|
|
171. After we get our running
torque on our pinion we will want to do a final recheck
of our gear mesh pattern... |
|
172. ... it should not have
changed. |
|
|
|
173. Our pattern remained
acceptable with little to no change.
|
|
174. This just tells us
we had it right.
Success! |
|
|
|
175. Next we will push our
axles back into place...
|
|
176. ...and push our U washers
back into place on the axles. |
|
|
|
177. The axles and U washers
go in very easy. |
|
178. During assembly, our
differential clutch spring got slightly moved, which prevented
the axles from fully seating when pulled on. |
|
|
|
179. Simply lightly tap
the differential clutch spring into place so that the
U washers slide between the openings. |
|
180. Pull again, if the
axles do not show in the differential pinion shaft hole
as they did above then they are fully seated. |
